ZRS C4 CONTROLS

4-Channel Band Pass Configuration.

The ZRS C4 features a unique band pass system where by channels 1 and 2 can be configured to a band pass system while separately setting channels 3 and 4 to their own band pass frequencies. This band pass system is especially useful when installing multiple midrange and tweeter speakers. Please see below for detailed instructions.

Set Channels 1 and 2 Crossover Switch to BPF (Band Pass Filter) and adjust the HPF (High Pass Filter) knob to the frequency you wish to choose to block low frequency signals. In the drawing below we set the knob to approximately 30Hz. Set the LPF (Low Pass Filter) to the frequency you wish to choose to block high frequency signals, we chose 300Hz. Now channels 1 and 2 will only play signals between 30Hz and 300Hz.

Set Channels 3 and 4 Crossover Switch to BPF (Band Pass Filter) and adjust the HPF (High Pass Filter) knob to the frequency you wish to choose to block low frequency signals. In the drawing below we set the knob to approximately 30Hz. Set the LPF (Low Pass Filter) to the frequency you wish to choose to block high frequency signals, we chose 300Hz. Now channels 1 and 2 will only play signals between 30Hz and 300Hz.

The Band Pass Setting is especially useful when setting up component speakers where you want to activly block low frequencies from reaching your midrange speakers and tweeters and for multiple midrange speaker installations. When using a 3-way amplifier system installation, the ZRS C4 is the perfect midrange/midbass power amplifier.

Channels 1 and 2 electronic crossover features sophisticated 12dBHigh Pass filter circuitry. The 12dB filter ensures a more gradual cutoff necessary for front speaker stages and tweeters where frequency overlap is critical for high quality sound reproduction,

Channels 3 and 4 electronic crossover features sophisticated Linkwitz-Riley 24dB Low Pass filter circuitry. The 24dB filter ensures a steep cutoff of high frequencies and assists the amplification circuitry emphasize its power output in the set frequency range thereby increasing the audio spectrums headroom.

The ZRS C4 features heavy duty bolt down terminals, the power and ground terminals accept 4 gauge wire while the speaker terminals can accept 10 gauge wire.

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.

If your unit has been professionally installed please do not change the gain settings set by the installer, he is the professional!

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.
