One of the difficulties in adding aftermarket amplifiers and speakers to an OEM system is having enough input channel flexibility to integrate properly with that systems output capabilities. With 4 pairs of independent channel inputs the coe8 provides nearly limitless install versatility.

The coe8 features an auxiliary input function that allows you to select between the main source unit or a second source such as an iPod or other portable device. The remote level control doubles as the switch for the auxiliary input.

The coe8 has a unique signal sense feature that detects signal on the input and turns the unit on without the need of a 12-volt trigger at the remote in (turn on) connection. Whether you are using the remote in or the signal sense function the coe8 has a remote out feature that will turn on your amplifiers or other devices.

All of the channels of the coe8 can be blended or summed to the main channel (channel 1) so even if you only have one pair of stereo inputs you can still use all four channels of output. The coe8 will accept direct input as well so each output channel receives its input signal from the corresponding channel input.

Line-Out Converter Specifications

Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
