Example-2: Factory Radio & AUX
Note: For systems with a main speaker level source and an auxiliary source, select system Type-2 at the multi-function
remote. This provides master volume control for AUX input as well as independent CH3/4 level adjustment for both
sources. In this 5-channel system example, note that the link4’s CH1/2 output needs to be split with y-adapters for the
amplifier’s front/rear channels (unless it has an input select switch) in order to reserve CH3/4 for sub level control.
Adjust for any desired gain difference between front and rear at the amplifier.
Example-4: Fixed High Level & AUX
Note: For factory amplified systems where the only clean signal without DSP effects such as speed dependent EQ,
limiters, crossovers, etc. is a fixed high level (e.g. volume control via CAN bus), select system Type-4 at the multi-function
remote. This enables all remote functions and sets knob priority to master volume control for both Main and AUX inputs.
Independent CH3/4 level mode is also selectable for each source. In this system example, the factory amplifier is
completely bypassed and all speakers are connected to the aftermarket amplifier.

Note: For stand-alone systems where only the AUX input is used, select system Type-3 at the multi-function remote.
This disables the remote’s source select function and sets knob priority to master volume control for AUX input.
Portable devices such as smartphones or MP3 players typically have an output voltage of 1Vrms or less, so it is
recommended to maximize the device’s unclipped output level. Adjust AUX gain accordingly and use the remote for the
system’s master volume.
