AUDIO OUTPUTS
Configurations
You can configure the MS-8’s eight outputs in a variety of ways, depending on the speakers that are
installed in your vehicle. You can configure the MS-8 for a system with one-way (full-range), two-way or
three-way front speakers, a one-way or two-way center speaker, side speakers, rear speakers and one
or two subwoofers. Remember, however, that the total number of available channels is eight, so any
combination of front, center, side, rear and subwoofer channels cannot total more than eight. For example,
if you are allocating six channels for a pair of tri-amped, three-way front speakers, there will be only two
remaining channels, which will not accommodate a pair of rear speakers and a subwoofer.
If your system will include more than eight channels, use additional separate amplifiers (connected to the
MS-8’s line outputs) for the additional channels. For example, if you want to build a 7.1-channel system
that includes bi-amped or tri-amped front speakers, use the MS-8 to generate the 7.1-channel outputs
(seven full-range and one subwoofer). Connect the MS-8’s front line outputs to the inputs of an additional
crossover (or amplifier containing an additional crossover) that will provide the separate channels required
to drive the front midbass, midrange and/or tweeters separately.
Use the Configuration Chart below to record which of your system’s speakers you have connected
to which of the MS-8’s outputs. Keeping this record will simplify channel assignment during the setup
procedure. See Main Menu
, on page 35.
