Thank you for purchasing this Cadence United Series amplier. Over the years, the technology used to create audio

ampliers has grown by leaps and bounds. We have tens of thousands of satised customers still using our rst generation

Ultra Drive ampliers which are more than 16 years old. Our competition is satised with just continuing to build the same

units year after year without thought for improvement, but not Cadence. We consider it our mission to use our expertise in

developing the latest technologies and to bring you the absolute best sounding, most powerful ampliers on the market and

of course at a reasonable price. We are very proud to introduce this fth generation of ampliers, the United Series featuring

C-FORCE technology, “ARVA” and “ADR” circuitry. You will be amazed at the quality and power that these new amps oer.

You will “Boom-Harder!” with United Series ampliers.

We have spared no expense in designing these ampliers, creating the most rugged, reliable, powerful and best performing

ampliers. In fact we are so sure of the quality we backup every United 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.

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:

United 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 United 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 18dB 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 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 United 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 United 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.
