In fact we are so sure of the quality we backup every Flash Series amplier with our exclusive two-year warranty which exemplies our commitment to excellence in car audio musical reproduction. (See enclosed warranty card for details.)

Please read this installation guide carefully for proper use of your Cadence power amplier. Should you need technical assistance during or after your installation please call our technical-line 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 amplier 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 ampliers at high volume levels while driving will impair your ability to hear necessary trac 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 amplier, secure it tightly. An unmounted amplier 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.

FEATURES

GOLD PLATED TERMINALS:

All the terminals on the amplier 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 amplier, be sure to strip just enough wire that ts into the terminal so that bare wires do not touch each other, or the amplier chassis and cause a short circuit. We recommend using Cadence brand lug and spade connectors for optimum signal transfer.

POWER AND PROTECTION CIRCUITRY:

Flash Series ampliers feature our unique IC controlled protection circuitry. This sophisticated circuit constantly monitors the heat sink internal temperature and various voltages, adjusting the amp automatically and protecting it from dangerous conditions. The 2 LED’s located on the side of the amplier provide indication of the amplier status, the Power LED will light when the amplier is receiving proper power, ground and remote voltages and the IC monitoring sequence indicates the amp is functional. In case the amplier encounters a diagnostic condition as listed below, the second LED will light indicating a Diagnostic condition. When a diagnostic condition is sensed the amplier will then turn into a self preservation mode and if the cause of the diagnostic condition is not corrected will eventually shut down. There are certain critical diagnostic conditions which will turn the amplier o immediately.

1. Speaker short circuit.

2. Input Overload.

3. Thermal overload.

4. Reverse Polarity.

To reset the amplier, you must rst diagnose what caused the problem, correct the fault and restart the system. See the Trouble Shooting page for further details.

MUTE CIRCUIT:

The Flash Series ampliers feature an anti-thump, mute and delay circuit. This eliminates irritating speaker damaging turn-on and turn-o transients normally experienced with less expensive ampliers.

BASS DRIVE EQUALIZATION CIRCUITRY:

A narrow “Q” shelving equalization circuit is included in the ampliers. The equalization system is preset at 45Hz. The boost control allows you to add up to 12dB of Bass Drive eect. 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 12dB 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 Flash Series ampliers 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 amplier 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.

SUPER CLASS AB AUDIO STAGE PERFORMANCE

The audio output section of the Flash Series ampliers feature Japanese studio grade, high current Bi-Polar audio transistors. Unlike other manufacturers who use a host of dierent 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 ampliers. These transistors were designed and engineered to produce music. That’s why Cadence ampliers clearly sound better. They are cleaner with lower distortion, higher current capable and more reliable. We challenge you to test listen a Cadence amplier and hear the dierence yourself.

FEATURES

“ARVA” - AUTOMATIC RAIL VOLTAGE ADJUSTMENT CIRCUITRY:

Cadence Flash 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 Flash Series amplifiers have tighter sounding bass reproduction thanks to this unique circuitry.

BATTERY VOLTAGE:

Cadence Flash 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

14.4 volts while the minimum voltage is 12 volts.

*** DO NOT EXCEED 14.4 INPUT VOLTAGE. ***

Though capable of high power reproduction, Cadence Flash Series amplifiers are not competition style amplifiers! They were designed for audiophile sound reproduction.

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 awlessly 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 Protection LED will light, indicating 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 nd that your speakers and speaker wires are not shorted, please check your ground connection.

Input Overload Protection: This circuit will either shutdown the amplier completely or make the amplier spurt on and o indicating that it is in a diagnostic condition. Turn the system o and reduce the gain on the amplier or volume from your head unit, this should result in a corrected condition.

DC Oset Protection: Should any DC voltage try to enter the amplier via the speaker terminals it will cause the amplier 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 amplier 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 amplier. Cadence ampliers operate on 12-volt negative ground systems only.

It is recommend that you layout your sound system design on paper rst. This will help you during the installation so that you will have a wiring ow chart and not miss-wire any of your components.

Mount the amplier in the trunk or hatch area of your vehicle. Never install an amplier in the engine compartment or on the rewall. Please be sure to leave breathing room around the amplier heat sink so that it can dissipate the heat it produces eciently. The amplier can be installed either horizontally or vertically.

When mounting the amplier on the trunk oor, be sure to watch for your gas tank, gas lines and elec trical lines. Do not drill or mount any screws where they might penetrate the gas tank of your car.

INSTALLATION BASICS

SETTING THE CONTROLS:

AUDIO PREAMP INPUT

The Flash Series ampliers feature RCA pre amp inputs. Run RCA cables from your sound source to the inputs of the amplier. 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 amplier.

USING THE BUILT-IN LOW PASS ELECTRONIC CROSSOVER

All the Flash Series ampliers 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. Now the knob marked FREQUENCY will control the low pass frequencies from 30Hz to 250Hz. 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 the ampliers for component speakers or co-axials, you will want to set the CROSSOVER MODE switch to HIGH PASS. The FREQUENCY control knob adjusts the high pass frequencies between 30Hz and 300Hz. Do not attach tweeters directly to the amplier, (even in the high pass mode) without a secondary passive crossover to protect them. 250Hz 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 amplier’s CROSSOVER MODE selector to HIGH PASS while setting the FREQUENCY 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.

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 amplier on and o 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.

POWER/GROUND WIRING:

The Flash Series ampliers 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 oers protection against damage from short circuits to the car chassis between the battery and the amplier. A second fuse closer to the amplier oers additional safety to the amplier itself. This fused red power wire should be attached to the amplier power terminal marked 12V+.

The wire harness should be made of red primary cable of at least 8 gauge for the F200-2 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 amplier 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 ampliers, mount them in close proximity so that they can all share the same ground point. Attach the black ground wire to the amplier screw terminal marked Ground.

We recommend that you use the Cadence AMPKIT4 or AMPKIT8 amplier installation kits, which contains all the cabling and accessories necessary for a good, reliable installation.

Over the years we have received ampliers 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 amplier 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 amplier 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.

INSTALLATION BASICS

ADJUSTING THE SYSTEM

Once the system is operational, the rst thing to do, is set all crossover points to approximate settings. In the case of the basic sub woofer system Low Pass lter crossover at 100 Hz or so. Set the Bass Boost equalizer controls to 0 dB ( Flat Switch Position.)

Now you should set the ampliers Input Sensitivity adjustment. The knob accessible on the side of the amplier marked INPUT GAIN adjusts the input sensitivity from 150mV to 5Volts.

To adjust the input sensitivity, turn the control using a small at 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 amplier 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 amplier’s gain separately. Start o with the bass amplier, then adjust the highs amplier’s level control to match.

Once you are satised 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 ampliers level controls.

*** The level control of any car amplier 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 amplier. Do not adjust the amplier 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 rst setting up the system.

USING THE ELECTRONIC CROSSOVER - 4 CHANNEL MODEL

The four channel models feature separate crossovers for channels 1-2 and 3-4. All the Flash Series ampliers feature 12dB per octave fully adjustable low-pass and high pass electronic crossovers. Mono Block bass amps feature 24dB 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 sub woofer channel. Bridge channels

3 and 4 for second high power sub woofer 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 30Hz to 250Hz. 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 ampliers for component speakers or coaxial, you will want to set the CROSSOVER MODE switch to HIGHt PASS. The FREQUENCY control knob adjusts the high pass frequencies between 30Hz and 250Hz. Do not attach tweeters directly to the amplier even in the high pass mode without a secondar y passive crossover to protect them. 250Hz high pass is not a frequency high enough for tweeters.

SUBSONIC FILTERING

MOUNTING AND WIRING

MOUNTING THE AMPLIFIERS:

Choose a convenient mounting location with unobstructed airow.

The Flash ampliers feature four mounting tabs located at the ampliers four corners. Using the supplied screws and grommets, gently mount the amplier in to position.

*** Do not over tighten the screws.***

OEM RADIO INTEGRATION WITH AUTOSTART

This newest series of Flash ampliers features our newest circuitry innovation. Say for example you are trying to integrate the Cadence Flash amplier in to a system with an OEM radio which does not have RCA output jacks or a remote turn on wire for the amplier, until now you would have had to congure a complicated relay system to turn on the amplier and use en external high-low converter to send the signal in to the amplier.

But now all you need to do is to wire your speakers to the included High Level Input harness and plug the harness in to the amplier. When you turn on your OEM head unit, the amplier will receive the music signal and automatically turn on the amplier. When you turn o the head unit, the amplier will automatically turn o after a 60 second built-in delay.

Do not use RCA and High Level Input at the same time.

Do not keep the speakers hooked up to the High Level Input once you are using them as the ampliers signal input.

The ideal ground point for the High Level Input harness is the radio ground, if thats not possible to reach any good chassis ground point will do.

Hook up Left and Right Speakers normally as per diagram using high pass lter capacitors. Wire one subwoofer to the bridged channel utilizing a low pass lter inductor. You must use this capacitor and inductor system when using 4 ohm speakers and woofers.

You can eliminate the need for the capacitors and inductor if you use 4 ohm speakers for the Left and Right Channel and an 8 ohm woofer for the bridged channel.

2 CHANNEL AMP BRIDGED MONO

When bridging Cadence two channel ampliers, the lowest impedance for the bridged channel is 4 ohms. Set the crossover switch to Low Pass and Crossover Frequency Setting to 100 Hz as a beginning point for tuning your system. Dial in as much Bass Drive as necessary keeping in mind that too much Bass Drive can add unnecessary distortion to your system.

Utilize the Remote Subwoofer Level control for bass control from the comfort of your vehicles interior. You must use the cable that was supplied with the amplier for the remote control. Use of standard phone cables can short out the amplier.

If you misplace your cable, please contact us at 800.477.2328 to procure a replacement or contact your local Cadence dealer.

Should your head unit have an additional subwoofer RCA output, that typically needs to be attached to a separate subwoofer amplier.

When conguring a 4 channel amplier 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 in to RCA Channel 1, then mix channels 2 and 4 and input them in to RCA Channel 2. The result will be preserved Left and Right balance with constant subwoofer output.

Two F1200-1D can be ridged together for double the power output into a 2-ohm load. Though each amp is 1 ohm stable, when bridging ampliers, you must bridge them to a 2 ohm load.

Input the head unit signal into the MASTER amplier and set the Bridged Mode switch to Master. Use the supplied DATA CABLE to send the fully processed signal from the MASTER amplier to the secondary SLAVE amplier and set the Bridged Mode switch to Slave. Do not input any high level or RCA signals into the Slave amplier.

All crossover controls, Bass Drive, frequency settings, and subsonic lter settings will be controlled by the Master Amplier including input gain levels. There is no need to gain match the two ampliers, it will occur automatically. The remote dash bass control should be plugged in to the Master amplier and it will control both ampliers.

Make sure to use the supplied DATA CABLE for linking of the ampliers 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 ampliers to two independent 1 ohm woofers as long as you don’t bridge the two ampliers outputs together.

Once again, when bridging two ampliers together, the nal impedance load of the bridged ampliers should be no lower than 2-ohms. Double power will occur at 2-ohms.

Master ampliers positive (+) speaker terminal should be wired to the positive terminal of the subwoofer. Slave ampliers 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 amplier and the Negative (-) terminal of the Slave amplier.

Please see diagram for a detailed drawing.

When daisy chaining two ampliers 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 conguration you gain the advantage of having one ampliers’ preamp section control both ampliers, eliminating the need to gain match and crossover match your system between ampliers.

Please note that the minimum impedance load for single Cadence Flash Ampliers is 2 ohm stereo and 4 ohm mono bridged.

Lower impedance loads will cause overheating and may damage the ampliers.

Do not mix dierent impedance speakers in series and / or parallel combinations, as unequal power sharing and acoustic outputs will result.

Due to constant product improvements, these specifications are subject to change without notice.

Though we tried our best to insure that this manual is free and clear of errors please don’t hold us responsible for printing errors.
