Operation and Function

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.

Input Gain Adjustment- This control matches the input level of your

coe8 with the output level of your source unit.

Power Indicator- This LED indicates when the coe8 is powered on.

Maximum Indicator- This LED indicates when the signal is at its

maximum level before distortion occurs. When the input "Gain"

adjustment is set correctly and the source unit is at its maximum

volume this LED should flicker intermittently.

Summing Indicators

- These LED's indicate when a channel is being

summed with the main channel.

RCA Outputs- These RCA output jacks provide a full range signal to

your amplifier. Channel 4 has one additional feature. When there is

no signal present on Channel 4, Channel 3's input will automatically

be sent out Channel 4.

AUX Input- This RCA input jack allows you to connect an additional

source to the coe8 such as an Ipod.

Remote Control- This port is for the dual function Caché remote

control (Included). The first function is source selection. Pushing

the control knob in will toggle the coe8's input between the AUX and

Main channels. The second function allows the user to control the

level of Channel 4's output up to the maximum adjustment level set

on the coe8. This control does not add any additional gain, it only

attenuates the level at which the coe8 was set.

High Level Inputs- Each terminal block allows for a high level left and

right channel signal to be input from the source unit. All four inputs

are full range inputs.

Installation Guidelines

INSTALLATION PRECAUTIONS

• Always mount the unit in a fashion so that it can be easily accessible for making

adjustments.

• Avoid mounting the unit to subwoofer enclosures or high vibration areas.

• Do not cover the unit with carpet or any other material.

• 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.

•Use rubber or plastic grommets to protect wires when routing them through metal.

•Always keep signal wires away from high current power wires.

•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 ground

ed 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 bat

tery. 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

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.

Remote Out

This Caché unit is equipped with a signal sensing circuit that can detect a signal on

its input and provide a +12V output signal to turn on an aftermarket amplifier. Connect

this to the remote terminal on an aftermarket amplifier.

Internal Jumper Options

Isolation Jumpers- This jumper provides three different ground isolation

options for the input of the coe8. The three input options include GND,

Isolation, and 200ohms. Make sure the coe6 is turned off before making

your selection.

Blending Jumpers- These jumpers are used to select either a Direct

(separate) or a Blended (summed) output. In the direct position the signal

on an individual channels input will come out the same channels output. In

the blended position the signals on two or more channels can be combined

with Channel 1 to provide one full range output. All of the channels that have

been selected to have their inputs blended will be combined and output onto

Channel 1. Each of the remaining channels being blended (2, 3, & 4) will

have the same signal on their channels output as what is on their input (not

a full range output like Channel 1).
