(See enclosed warranty card for details.) Please read this installation guide carefully for proper use of your Cadence power amplifier. Should you need technical assistance during or after your installation please call our technical-line M - Th between 9:30 am and 5:00 PM EST at (732) 370-5400. Read this entire guide fully before attempting your installation. WARNING: BE AWARE! Use of this amplifier at extreme high volumes for extended periods of time may cause hearing loss and or hearing damage. During periods of prolonged high volume levels it is recommended that you use ear safety devices. Playing Cadence amplifiers at high volume levels while driving will impair your ability to hear necessary traffic sounds. While driving always keep your sound volume at reasonable levels. We at Cadence want you listening for many years to come. When installing the amplifier, secure it tightly. An unmounted amplifier in your car can cause serious injury to passengers and damage to your vehicle if it is set in motion by an abrupt driving maneuver or short stop. INTRODUCTION Page 3 2 FEATURES 34 3 GOLD PLATED TERMINALS: All the terminals on the amplifier are solid brass and gold plated for high conductivity and minimum impedance loss. The power and ground terminals are extra large and capable of accepting 4-8 gauge wire. The speaker terminals can accept 14-16 gauge wire. When wiring the amplifier, be sure to strip just enough wire that fits into the terminal so that bare wires do not touch each other, or the amplifier chassis and cause a short circuit. We recommend using Cadence brand lug and spade connectors for optimum signal transfer. MUTE CIRCUIT: The ZRS Smart Series amplifiers feature an anti-thump, mute and delay circuit. This eliminates irritating speaker damaging turn-on and turn-off transients normally experienced with less expensive amplifiers. BASS DRIVE EQUALIZATION CIRCUITRY: A narrow “Q” shelving equalization circuit is included in the amplifiers. The equalization system is preset at 45Hz. The boost control allows you to add up to 18dB of Bass Drive effect. Utilize the Bass Drive to tailor your bass response to your systems needs. Please keep in mind that by adding Bass Drive you are adding stress on your speakers. Make sure your speakers can handle the extra power output! It would be foolish to add 18dB of gain to low excursion 8” and 10” Sub woofers or mid ranges and tweeters. It’s a sure way to blow your speakers. The Bass Drive was designed for High Power sub woofers. “ADR”: ACTIVE DYNAMIC REGULATION Cadence ZRS Smart Series amplifiers feature our proprietary ADR, Active Dynamic Regulated power supplies. 100% HexFET devices are utilized in the power supply for high speed (100KHz) switching frequencies. The power supplies are capable of supplying the main amplifier with a considerable amount of reserve voltage for peak “high demand” situations. The ADR circuit provides full bandwidth power for authoritative bass response, high current output into low impedance loads and increased headroom. The ADR is supplied with power via a high speed, high temperature capacitance bank and 100% pure copper rails on the PCB enabling fast transient response to musical demands. “ARVA”: AUTOMATIC RAIL VOLTAGE ADJUSTMENT CIRCUITRY Cadence ZRS Smart Series amplifiers feature “ARVA” circuitry in their power supply. This circuit constantly monitors the output stage and under high current demands will adjust the power supply rail voltages so that enough power is available for peak situations. The “ARVA” also improves the damping factor of the amplifier when playing low impedance mono loads. Cadence United Series amplifiers have tighter sounding bass reproduction thanks to this unique circuitry. SUPER CLASS AB AUDIO STAGE PERFORMANCE: The audio output section of the ZRS Smart Series amplifiers feature Japanese studio grade, high current Bi-Polar audio transistors. Unlike other manufacturers who use a host of different type of transistors, not originally designed for audio output, i.e.: power supply transistors, motor control transistors to produce the audio signal, (You can only imagine what they sound like.) Cadence uses only true audio transistors in the audio section of these amplifiers. These transistors were designed and engineered to produce music. That’s why Cadence amplifiers clearly sound better. They are cleaner with lower distortion, higher current capable and more reliable. We challenge you to test listen a Cadence amplifier and hear the difference yourself. SUPER CLASS D FULL RANGE: The D250.2 and D350.2 utilize our cutting edge full range class D technology. These amps feature sound that is crystal clear and ultra smooth without the distortion or harshness typical of full range class D designs. CLIP LIMITER (MONOBLOCK AMPS ONLY): When activated this feature stops your amp from going into clipping mode thus limiting the amount distortion. This is achieved by compressing the signal coming into the amp. For SPL applications turn limiter off. For SQL applications leave the limiter on. BASS FOCUS: The ZRS Smart series amplifiers feature our exclusive BASS FOCUS circuitry which works as a variable Q control. By supplying up to 7dB of boost, you can compensate for drivers in to small an enclosure so a 10” woofer can sound like a 12” woofer and a 12” can sound like a 15” woofer. Small dash and door speakers will also benefit increasing their power handling capabilities.

INDICATES NO DISTORTION DETECTED, ALL SYSTEMS NORMAL + 14.7V DISTORTION FREE 23°C CADENCE D100.4 SMART TECH MONITORING CIRCUITRY: ZRS Smart Series amplifiers feature our exclusive Smart Tech monitoring circuit. The system computer monitors amplifier temperature, input voltage, channel distortion with clipping, input overload, and speaker short circuit. This information is displayed on the top mounted easy to read LCD screen notifying the user of the amplifiers status at all times. Page 4 6 BATTERY VOLTAGE: Cadence ZRS Smart Series amplifiers are rated and regulated to 13.8 volts and below. Increasing voltage to 14.4 volts will increase the power output of the amplifier in the same proportion. Maximum input voltage is 16 volts while the minimum voltage is 12 volts. *** DO NOT EXCEED 16 INPUT VOLTAGE. *** PROTECTION CIRCUITRY: Cadence amplifiers incorporate many outstanding protection circuits to help protect the amplifier from being damaged during operating conditions. Thermal Protection: When the amplifier reaches an unsafe operating temperature of 80 degrees Celsius the amplifier will turn off. Once the amplifier cools down, simply reset the amplifier by its Remote connection, (turn the amplifier off and then on again once you have given the amplifier a chance to cool down) and the amp will once again begin to play. If you live in a hot climate we suggest installing additional cooling fans in your trunk to exhaust the hot air which can build up in the trunk this will help keep the ambient temperature in the trunk as low as possible so that your amps work flawlessly and without any musical interruption. Speaker Short Circuit Protection: Should your speakers short circuit due to voice coil burn out, or should the amplifier sense an impedance too low to handle the LCD display will indicate a diagnostic condition. Turn off your system, disconnect one speaker at a time and try to determine which speaker might be faulty. Correct the condition and restart the amplifier. You must reset the amplifier by turning it OFF and then ON again by the Remote power connection after correcting a diagnostic condition. (Turn your radio off and then on again.) Clipping or total shutdown may also be a result of a bad ground connection or loose ground. If you find that your speakers and speaker wires are not shorted, please check your ground connection. Input Overload Protection: This circuit will either shutdown the amplifier completely or make the amplifier spurt on and off indicating that it is in a diagnostic condition. Turn the system off and reduce the gain on the amplifier or volume from your head unit, this should result in a corrected condition. DC Offset Protection: Should any DC voltage try to enter the amplifier via the speaker terminals it will cause the amplifier to shut down and not operate until this condition is remedied. This circuit will also protect damaging high DC voltages from reaching your speakers should your amplifier ever malfunction. INSTALLATION BASICS: Before you begin with your installation, disconnect the NEGATIVE (-) terminal from your car’s battery. This safety precaution will avoid possible short circuits while wiring your amplifier. Cadence amplifiers operate on 12-volt negative ground systems only. It is recommend that you layout your sound system design on paper first. This will help you during the installation so that you will have a wiring flow chart and not miss-wire any of your components. Mount the amplifier in the trunk or hatch area of your vehicle. Never install an amplifier in the engine compartment or on the firewall. Please be sure to leave breathing room around the amplifier heat sink so that it can dissipate the heat it produces efficiently. The amplifier can be installed either horizontally or vertically. When mounting the amplifier on the trunk floor, be sure to watch for your gas tank, gas lines and electrical lines. Do not drill or mount any screws where they might penetrate the gas tank of your car. REMOTE TURN ON CONNECTION: The remote turn on connection is located on the barrier strip next to the power and ground connections. This connection is responsible for turning the amplifier on and off with the rest of the system. A smaller gauge wire can be used to make this connection to your radio’s power antenna lead. Should your system not have any turn on leads, you can wire the remote terminal to an accessory lead, which turns on, with your cars ignition. your sound source to the inputs of the amplifier. We suggest the use of high quality shielded RCA patch cords to help reduce and eliminate unwanted electrical noise to your system. Be sure to run the RCA cables on the opposite side of the vehicle that you used to carry the power and ground leads of the amplifier. USING THE BUILT-IN LOW PASS ELECTRONIC CROSSOVER All the ZRS Smart Series amplifiers feature 12dB per octave fully adjustable low-pass and high pass electronic crossovers. For Low Pass sub woofer systems, set the CROSSOVER MODE switch to LOW PASS. For 2 channel amps the knob marked LPF will control the low pass frequencies depending on the model anywhere from 45Hz to 250Hz. The D250.2, D350.2, and D100.4 feature a frequency multiplier button (10X) allowing you to reach frequencies ranging from 150Hz to 4.5KHz. A frequent error made is setting the low pass frequency too low, especially when using vented sub woofer enclosures. We recommend that for most installations you do not set the frequency knob lower than 80 - 100Hz (the 12 o’clock position). When using D250.2, D350.2, and D100.4 amplifiers for component speakers or co- axials, you will want to set the CROSSOVER MODE switch to HIGH PASS. The HPF control knob adjusts the high pass frequencies between 10Hz and 300Hz. These amplifiers also feature a frequency multiplier feature (15x) allowing you to reach frequencies ranging from 150Hz to 4.5Khz. Do not attach tweeters directly to the amplifier, (even in the high pass mode) without a secondary passive crossover to protect them. 300Hz high pass is not a frequency high enough for tweeters. SUBSONIC FILTERING For sub woofer installations with a passive LP crossover, you can set the amplifier’s CROSSOVER MODE selector to HIGH PASS while setting the HPF knob to 30Hz, this will act as SUBSONIC FILTER for all signals below 30Hz. This is especially useful for vented enclosures where the port tuning frequency falls below the sub woofer tuning frequency to protect against sub woofer unloading. POWER/GROUND WIRING: The ZRS Smart Series amplifiers are supplied with built-in fuses, never replace the fuse that the amp came with, with one of a larger value. We suggest you construct a Red wiring harness with 2 additional fuses. One fuse should be located near the car battery. This fuse near the battery offers protection against damage from short circuits to the car chassis between the battery and the amplifier. A second fuse closer to the amplifier offers additional safety to the amplifier itself. This fused red power wire should be attached to the amplifier power terminal marked 12V+. The wire harness should be made of red primary cable of at least 8 gauge for the D250.2 and at least 4 gauge for all other larger models. The harness should terminate in a large ring terminal for connection directly to the positive terminal of the car battery. Use a spade plug to attach the wire, which connects to the amplifier location marked 12V+. A second black color wire of equal gauge should be used as a ground connection to a welded chassis member. When connecting the ground wire make sure that there is no paint or other insulator blocking a good ground connection. When installing multiple amplifiers, mount them in close proximity so that they can all share the same ground point. Attach the black ground wire to the amplifier screw terminal marked Ground. We recommend that you use the Cadence AMPKIT4 or AMPKIT8 amplifier installation kits, which contains all the cabling and accessories necessary for a good, reliable installation. Over the years we have received amplifiers back to our service department with melted power/ground terminals. The cause of this is a bad ground connection. When there is a lack of good ground, heat builds up at the weakest point which happens to be the contact screw of the amplifier terminal. Over time the heat generated will begin to melt the terminal. It is a good practice to feel the power and ground wires with your hands, near their amplifier connection after having played the amp for a while. If the wires feel hot to the touch you probably have a bad or loose connection. If you are sure of your connections and the wires still feel hot to the touch, you should upgrade the gauge of wire to next heaviest gauge. SETTING THE CONTROLS: AUDIO PREAMP INPUT The ZRS Smart Series amplifiers feature RCA pre amp inputs. Run RCA cables from INSTALLATION 5 Page 5 SPEAKER 1 Ω MINIMUM REM POWER 7 8 ADJUSTING THE SYSTEM Once the system is operational, the first thing to do, is set all crossover points to approximate settings. In the case of the basic sub woofer system Low Pass filter crossover at 100 Hz or so. Set the Bass Boost equalizer controls to 0 dB ( Flat Switch Position.) Now you should set the amplifiers Input Sensitivity adjustment. The knob accessible on the side of the amplifier marked INPUT GAIN adjusts the input sensitivity from 150mV to 8 Volts. To adjust the input sensitivity, turn the control using a small flat head screwdriver fully counter clock wise to the minimum position. Do not apply any pressure while turning as this might break the control unit. Adjust your radio volume level to maximum volume. Now turn the level control on the amplifier clockwise towards the Maximum marking until audible distortion occurs. When you begin to hear any distortion in the sound, back down one notch and your amp is set. It is helpful to have a second person to help you set the gain. When setting up a multi-amp system, set each amplifier’s gain separately. Start off with the bass amplifier, then adjust the highs amplifier’s level control to match. Once you are satisfied with the level control settings, use any equalizer controls to adjust the system tonal level for personal preference. Keep in mind that after equalizing, you may have to go back and reset the amplifiers level controls. *** The level control of any car amplifier should not be mistaken for a volume control. It is a sophisticated device designed to match the output level of your source unit to the input level of the amplifier. Do not adjust the amplifier gain to maximum unless your input level requires it. If your unit has been professionally installed please do not change the gain settings set by the installer, he is the professional! Your system can also be extremely sensitive to noise when the LEVEL is set to maximum and does not match your input signal. The gain adjustments need to be made only once when first setting up the system. USING THE ELECTRONIC CROSSOVER - 4 CHANNEL MODEL (D100.4) The four channel model features separate crossovers for channels 1-2 and 3-4. All the ZRS Smart Series amplifiers feature 12dB per octave fully adjustable low- pass and high pass electronic crossovers. FOUR CHANNEL AMPLIFIER CONFIGURATIONS: 1. All four channels High Pass for internal component speakers in doors and rear decks. 2. Channels 1 and 2 High Pass for front component speakers, while channels 3 and 4 are wired to sub woofers. 3.Bridge channels 1 and 2 for single high power subwoofer channel. Bridge channels 3 and 4 for second high power subwoofer channel. For Low Pass systems, set the CROSSOVER MODE switch to LOW PASS. Now the knob marked FREQUENCY will control the low pass frequencies from 40Hz to 150Hz. A frequent mistake made is setting the low pass frequency too low, especially when using vented sub woofer enclosures. We recommend that for most installations you do not set the frequency knob lower than 100Hz (the 12 o’clock position). When using the amplifiers for component speakers or coaxial, you will want to set the CROSSOVER MODE switch to HIGH PASS. The FREQUENCY control knob adjusts the high pass frequencies between 50Hz and 500Hz. Do not attach tweeters directly to the amplifier even in the high pass mode without a secondary passive crossover to protect them. 500Hz high pass is not a frequency high enough for tweeters. PASSIVE SUBSONIC FILTERING For sub woofer installations with a passive LP crossover, you can set the amplifier’s CROSSOVER MODE selector to HIGH PASS while setting the FREQUENCY KNOB to 40Hz, this will act as SUBSONIC FILTER for all signals below 40Hz. This is especially useful for vented enclosures where the port tuning frequency falls below the sub woofer tuning frequency to protect against sub woofer unloading. MOUNTING THE AMPLIFIERS: Choose a convenient mounting location with unobstructed airflow. The ZRS Smart amplifiers feature four mounting tabs located near the amplifiers four corners. Using the supplied screws and grommets, gently mount the amplifier into position. *** Do not over tighten the screws.*** The ZRS Smart Series amplifiers are supplied with built-in fuses, never replace the fuse that the amp came with, with one of a larger value. We suggest you construct a Red wiring harness with 2 additional fuses. One fuse should be located near the car battery. This fuse near the battery offers protection against damage from short circuits to the car chassis between the battery and the amplifier. A second fuse closer to the amplifier offers additional safety to the amplifier itself. This fused red power wire should be attached to the amplifier power terminal marked 12V+. The wire harness should be made of red primary cable of at least 4 gauge for all ZRS Smart Series amplifiers. The harness should terminate in a large ring terminal for connection directly to the positive terminal of the car battery. Use a spade plug to attach the wire, which connects to the amplifier location marked 12V+. A second black color wire of equal gauge should be used as a ground connection to a welded chassis member. When connecting the ground wire make sure that there is no paint or other insulator blocking a good ground connection. When installing multiple amplifiers, mount them in close proximity so that they can all share the same ground point. Attach the black ground wire to the amplifier screw terminal marked Ground. We recommend that you use the Cadence AMPKIT4 or AMPKIT8 amplifier installation kits, which contains all the cabling and accessories necessary for a good, reliable installation. INSTALLATION MOUNTING AND WIRING BATTERY FUSE GROUND REMOTE TURN ON Terminal of head unit Page 6 9 10 If your head unit has only one pair of Left and Right RCA out put jacks, plug them in to RCA input Jacks 1 and 2 of the amplifier and set the Input model switch to the 2CH position. The amplifier preamp circuit will automatically route the signals to channels 3 and 4 thereby preserving your Left and Right Balance control but with no Fade control Front to Rear. The D100.4 features a unique CLONE FUNCTION to assist in setting up a 2-channel bridged system with perfect gain and crossover tracking between the speakers. Typically when setting up a system you would need to set up channels 1 - 2 and then channels 3 - 4 crossovers and gains separately not guaranteeing perfect balance or frequency cutoffs. By using the CLONE FUNCTION you can control channels 1 -2 from the processed signals of channels 3 - 4 thereby guaranteeing that all 4 channels are getting identical voltages and have their crossover settings identical at identical frequencies.

Then attach radio output Rear Left and Rear Right to Channels 3 and 4. Set the Input Mode Switch to 4Ch position. The pre amp circuitry will not mix any signals thereby preserving full Left to Right Balance and Front to Rear fader control. Should your head unit have an additional subwoofer RCA output, that typically needs to be attached to a separate subwoofer amplifier. When configuring a 4 channel amplifier to a 3 channel system, you can use an RCA Y adaptor to send the subwoofer preamp signal to channels 3 and 4 and bridge those channels to the subwoofer. Use Y adaptors to mix channels 1 and 3 and input them into RCA Channel 1, then mix channels 2 and 4 and input them into RCA channel 2. The result will be preserved Left and Right balance with constant subwoofer output.

Though each amp is 1 ohm stable, when bridging amplifiers, you must bridge them to a 2 ohm load. Input the head unit signal into the MASTER amplifier and set the Bridged Mode switch to Master. Use the supplied DATA CABLE to send the fully processed signal from the MASTER amplifier to the secondary SLAVE amplifier and set the Bridged Mode switch to Slave. Do not input any RCA signals into the Slave amplifier. All crossover controls, Bass Drive, frequency settings, and subsonic filter settings will be controlled by the Master Amplifier including input gain levels. There is no need to gain match the two amplifiers, it will occur automatically. The remote dash bass control should be plugged in to the Master amplifier and it will control both amplifiers. Make sure to use the supplied DATA CABLE for linking of the amplifiers and not the dash board bass remote cable or any other phone jack cable. If you misplace your cable, contact Cadence or your local dealer to procure a new one. This same input/control system can be utilized when daisy chaining two amplifiers to two independent 1 ohm woofers as long as you don’t bridge the two amplifiers outputs together.

Double power will occur at 2-ohms. When bridging two D800M OR D1600M amplifiers together, the final impedance load of the bridged amplifiers should be no lower than 4-ohms. Double power will occur at 4-ohms. Master amplifiers positive (+) speaker terminal should be wired to the positive terminal of the subwoofer. Slave amplifiers positive (+) speaker terminal should be wired to negative terminal of the subwoofer. Now connect a heavy gauge wire (12 Gauge) between the negative (-) terminal of the Master amplifier and the Negative (-) terminal of the Slave amplifier. Please see diagram on previous page for a detailed drawing. When daisy chaining two amplifiers for independent woofers, wire up the the woofers as you would typically wire them when installing individual systems, even down to 1-ohm. By using the MASTER/SLAVE input configuration you gain the advantage of having one amplifiers’ preamp section control both amplifiers, eliminating the need to gain match and crossover match your system between amplifiers.
