ZRS C3 CONTROLS
BAND PASS CONFIGURATION
The ZRS C3 can be configured for channels 1 and 2 in a bandpass mode and channels 3 and 4 in their band pass mode within their own
separate frequency range. By setting both the HPF (High Pass Filter) to the ON position and the LPF (Low Pass Filter) to the ON position you
can now adjust the top and bottom end frequency cut-off of all channels. See diagrams below for specific button/switch settings.
All ZRS Type C amplifiers
feature advanced input
gain control from 0.2 volts
to 8 volts so they can
operate efficiently and at
full power from any head
unit pre amp signal.

CROSSOVER
FREQUENCY MULTIPLIER
The ZRS C3 features in both
channels 1-2 and 3-4 fully
adjustable crossovers. We split
the ranges from 15Hz to 400Hz
for the High Pass and then added
a 10 times (X) Frequency
Multiplier switch that changes
the frequency range to 150Hz-
4KHz for channels 1 and 2. The
Low Pass can be changed from
40Hz-400HZ to 400Hz - 4KHz
range. This is especially useful for
band pass configurations.
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.
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 200mV to 8Volts.
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.
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.
If your unit has been professionally installed please do not change the gain settings set by the installer, he is the professional!

The ZRS C3, features heavy duty bolt down terminals,
the power and ground terminals accept 0 - 2 gauge wire
while the speaker terminals can accept 8 gauge wire.

Bandpass frequencies of all
channels can now be
adjusted from15Hz to 4KHz
dependant on how the
frequency multiplier is set.
FOUR CHANNEL
RCA INPUT
The ZRS C3,four channel RCA inputs which allows you
to have 4 channel balanced and faded signal from your
head unit. If your head unit has only 1 pair of RCA
outputs, you must use a “Y” adaptor to split the signal to
all four input channels.
When using the Remote
Subwoofer Control in a
multi amp system the
bass remote of the Master
amp will control all amps
in the system. Use only
cable supplied with the
remote for connection.
