CPA

GRAPHIC EQUALIZER

  • GRAPHIC EQUALIZER

    The source for your music has become portable in todays world. The storage of music is now dominated by mobile phones and small portable media devices and with the CPA preamplifier, it can integrate those devices into your audio system. The CPA offers a flexible auxiliary input that makes adding those devices into your car audio system seamless. Many times the input level of the main source unit (CD player, stereo tuner, factory radio, etc...) is higher than the level of portable media devices. The CPA has a variable input adjustment for the auxiliary source so the output level can be perfectly matched to the main source units level. The CPA comes with a multitude of features and is not limited to just adding another source to the vehicle. It is a pre-amplifier and line driver providing you with a stronger signal with master volume control. The CPA features a fully adjustable 7 band equalizer and variable low-pass crossover with subwoofer level control so you can make the necessary adjustments to how you want your music to sound.

    1. Power Connections-These connections are for input power, chassis ground, and remote turn-on. Use a minimum of 18 gauge wire for power and ground connections. The power wire should be fused with a 1 amp fuse.
    2. RCA Front & Rear Outputs- These RCA output jacks provide a full range signal to your amplifier.
    3. RCA Inputs- These RCA input jacks allow for a normal left and right channel signal input from the source unit.
    4. RCA Sub Outputs- These RCA output jacks provide a LP signal to your bass amplifier.
    5. AUX Input Gain Adjustment- This control matches the input level of your cpa with the output level of the source unit connected to the Aux input. When properly adjusted both sources (AUX and MAIN) should play at the same volume level. The adjustments are individual with one for the left channel and one for the right channel.
    6. LPF Frequency Adjustment- This controls the cutoff frequency of the LPF on the "SUB OUT" channels. The filter is variable from 50Hz to 150Hz.
    7. Volume Control- This raises and lowers the volume on all the cpa's outputs simultaneously.
    8. Subwoofer Level Adjustment- This raises and lowers the level of just the "SUB OUT" channels.
    9. Fader Adjustment- This allows you to adjust the level between the "Front" and "Rear" channels.
    10. Illumination Selector- Changes illumination around controls to red or blue.
    11. AUX Input Switch- This switch is used to select the input of the cpa. When the button is pressed in the "AUX" input is selected. In normal position the main input is active.
    12. qualizer levels Adjustment- There are seven different frequencies or bands that can be adjusted. Each band has an available adjustment of +/-10dB.

    INSTALLATION PRECAUTIONS

    1. Always mount the unit in a fashion so that it can be easily accessible for making adjustments.
    2. Avoid mounting the unit to subwoofer enclosures or high vibration areas.
    3. Do not cover the unit with carpet or any other material.
    4. Do not mount the unit in the engine compartment or anywhere that it will be subject to high temperatures, (ie, direct sunlight or heater) moisture, dust or dirt.
    5. Use rubber or plastic grommets to protect wires when routing them through metal.
    6. Always keep signal wires away from high current power wires.
    7. The ground connection should always be the first connection made.

    WIRING INSTRUCTIONS

    Ground Connection (GND)
    The main ground connection should be made between the Gnd terminal on the unit and a metal part of the vehicle close to the mounting location. This wire needs to be as short as possible to minimize the possibility of induced noise. You should use 18 gauge wire or larger for the ground connection. The metal point on the vehicle where the ground connection is made needs to have all paint removed and be scuffed down to the bare metal. The ground wire should have a ring terminal soldered to it and be bolted directly to the vehicle with the use of a star washer. Do not ground the unit near existing (factory) ground points. These areas generally have multiple devices grounded to them and can cause induced noise.

    Power Connection (+12V)
    The main power connection should be made at the battery. This will ensure that the unit receives the best possible connection to minimize noise. There must be an inline fuse (1 amp) placed in series with the unit. The fuse should be within 18" of the battery. You should use 18 gauge wire or larger for the power connection. The power wire should have a ring terminal soldered to it and be bolted to the vehicles battery. Do not install the fuse in the holder until all the systems connections have been made.

    Remote In (REM)
    This Caché unit is turned on by applying +12 VDC to the remote turn-on terminal. This terminal should be connected to the remote lead from the car stereo. This remote lead from the source unit will trigger a +12V output only when the car stereo is turned on. If the source unit does not provide a remote turn on you can use the accessory terminal in the cars fuse block. This will however turn the unit on and off with the key, regardless of whether the source unit is on or off.
