Signal Bus

The Signal Bus switch allows you to combine multiple input

signals to a single channel output. It is typically used when

connecting to a factory system that has dedicated speaker

outputs for the highs, mids and lows. You can use the Sum/Bus

function to sum those signals together to create a full range

output. Or, if the factory source only has front and rear full range output,

the Signal Bus can be set to route (bus) the audio signal from Channel 2 to

Channel 3 for that must-have subwoofer channel.

Below are some diagrams of typical scenarios of how you can setup your LC7i PRO

FRONT

REAR

SUB

In this example all three Signal Bus switches are set to the default setting of

Sep. (separate). There is no combining or routing of signals. What goes into

the Channel Input comes out the corresponding Channel Output.

FRONT

REAR

Add a sub channel to a 4 channel system by setting Channels 2 and 3 to Sum/Bus.

This will route the signal on Channel 2 to Channel 3.

HIGH

SUB

MID

LOW

To sum highs, mids, and lows to get a glorious full range signal, set all channels

to Sum/Bus. (Looks confusing on paper, but trust us, it will sound great)
