ZRS C1 CONTROLS

MASTER/SLAVE CONFIGURATION.

Whether you are daisy chaining or bridging two ZRS C1 amplifiers, our exclusive MASTER/SLAVE configuration insures the simplest installation possibilities. By

following the guidelines set up. While other brands have you gain matching, crossover matching and phase matching their amps in multi-amp installations, the Cadence

ZRS C1 system allows you to control ALL pre amp functions from the master amp including gains, crossovers and even the dashboard remote bass control. This system

allows you to install any number of amps in a bridged mode to double power to 2 ohm or in daisy chain mode for multi-woofer systems.

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 300mV to 7Volts.

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 C1 features our exclusive

BASS FOCUS circuitry which works

as a variable Q control at the

Subsonic Filter setting. By supplying

up to 7dB of boost you can

compensate for drivers in too small

enclosures so a 10” woofer can

sound like a 12” woofer and a 12”

woofer can sound like a 15” woofer. In

a vented enclosure set the Bass

Focus to the port tuning frequency

and you can add 7dB of increased

bass rumble.

ADJUSTABLE SUBSONIC

WITH BASS FOCUS

The crossover of the ZRS C1

features a steep 24dB per octave

slope Butterworth low pass

crossover ensuring that only the

lowest frequencies are reproduced

by the amplifier.

The amplifier also includes a Bass

Equalizer with a center frequency of

45Hz which can be adjusted for up

to 12dB of additional gain at that

frequency.

The super heavy-duty heat sink guarantees

that your amplifier will stay cool no matter

expense, cut no corners in designing,

engineering and building the ZRS C1. Each

amp is carefully assembled by a group of

highly skilled technicians and then tested

and burned in for a full 24 hours before being

released for delivery to you.
