BATTERY VOLTAGE:

Xenith Series amplifiers 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 top side of the amplifier provide indication of the amplifier status, the Power LED will

light when the amplifier is receiving proper power, ground and remote voltages and the IC monitoring sequence indicates the amp is functional. In case the amplifier encounters a

diagnostic condition as listed below, the second LED will light indicating a Diagnostic condition. When a diagnostic condition is sensed the amplifier will then turn in to 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 amplifier off immediately.

1. Speaker short circuit. / 2. Input Overload. / 3. Thermal overload. / 4. Reverse Polarity.

To reset the amplifier, you must first diagnose what caused the problem, correct the fault and restart the system. See the Trouble Shooting page for further details.

The Xenith 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.

All Xenith mono block amplifiers feature a narrow "Q" shelving equalization circuit. The equalization system is preset at 45Hz. The boost control allows you to +6dB or +12dB of Bass EQ

effect. Utilize the Bass EQ to tailor your bass response to your systems needs. Please keep in mind that by adding Bass EQ 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 EQ was designed for High Power sub woofers.

Cadence Xenith 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.

The audio output section of the Xenith Series amplifiers feature Japanese studio grade, high current Bi-Polar audio

transistors. Unlike other manufacturers who use a host of different type transistors, not originally designed for audio output, i.e.: power supply transistors, motor control transistors to

produce the audio signal, (you can only begin to imagine what they sound like.) Cadence uses only true audio transistors in the audio section of their 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.

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

WIRELESS PCB DESIGN

DO NOT EXCEED 14.4 INPUT VOLTAGE.

Cadence Xenith amps, feature black pcb designs with a clear solder mask. All circuitry has been designed on to the PCB and all high current traces are provided through heavy duty bus

bars or secondary pc boards. You wont find any wires looping around a Xenith amp typical of cheap amplifier designs. By engineering all circuitry directly to the PCB we are able to

produce a more powerful amp, that is more efficient and has lower distortion rates.
