We have spared no expense in designing these amplifiers, creating the most rugged,
reliable, powerful and best performing amplifiers. In fact we are so sure of the quality we
backup every ZRS Series amplifier with our exclusive two-year warranty which exemplifies
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 amplifier.
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 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.

We suggest you construct a Red wiring harness with 2 additional fuse. 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 primary cable of at least 4 gauge. 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 amplifier installation kits, which contain 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.

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.

The ZRS Series amplifiers feature RCA preamp inputs. Run RCA cables from 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.

To avoid electrical noise from being injected in to your sound systems 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.

BRIDGING AMPLIFIERS - HOW TO SET SWITCHES, INPUTS AND REMOTE CONTROL.

When bridging two amplifiers together all pre amp signals including crossover, phase control, bass equalizer, input gain, subsonic filter, bass focus are controlled by the Master amplifier.
The entire pre amp section of the Slave amplifier is bypassed. This is done so all you have to do is to set the Master amplifier and the Slave amplifier will match the Master exactly. There is no
need for any manual matching to occur. This ensures perfect alignment of your system. One Bass Control knob, plugged in to the Master amplifier will also control both amplifiers, thereby
simplifying your installation as well.

You can use the RCA Pre amp Output of the Master Amplifier to feed secondary Full Range Multi-Channel amplifiers for a Mult-Amp system.

Set Master Amplifier to “MASTER”

Set Salve amplifier to “SLAVE 2”

Set Phase Shift on both amps to same position.

Set all crossover setting, bass equalizer, subsonic filter, bass focus on MASTER amp to desired settings.

Use the “Bridging Cable” which was supplied with amplifier to connect MASTER OUT of amplifier #1 (Master) to SLAVE IN of amplifiers #2 (SLAVE). Do not substitute any other cable, if you
need a longer cable or lost your cable, please contact Cadence.

Connect a heavy duty speaker wire between the NEGATIVE terminals of both amplifiers.

Connect your woofers NEGATIVE TERMINAL to MASTER amplifiers speaker POSITIVE TERMINAL and your woofers POSITIVE TERMINAL to SLAVE amplifier POSITIVE TERMINAL.
