Example-2: Factory Amp + AUX (6-in/4-out or 6-in/6-out)
Notes:
Ÿ For systems with a main speaker level source that will serve as the master volume control, and an auxiliary source is
connected to the link6’s AUX input jack, select system Type-2 at the multi-function remote. This provides AUX volume
control as well as independent CH5/6 level adjustment for both main and AUX sources.
Ÿ As a typical factory amplified system example, a front 2-way signal needs to be summed to full-range for an
aftermarket component set with passive crossovers. However, there are several options for what to do for the rear and
subwoofer channels, depending upon frequency content and whether preserving front/rear fading is important:
¡ In this example the factory front door signal content is fine for components but its bass rolls off too high for a sub,
whereas the rear channel has enough bass content. Therefore CH5/6’s input select switch can be set to direct or
sum, depending on whether CH5/6’s signal is only used for bass or also routed to CH1/2 outputs as rear full-range.
¡ To preserve fader and prevent remote sub level adjustments from affecting rear speaker output, set CH5/6 input
select to direct, then select “5/6” at the CH1/2 output select switch to copy CH5/6’s internal signal and route to the
to CH1/2 RCA outputs for connection to the amp as full-range rear channels.

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 and use the remote for the system’s master volume.
