Connecting an aftermarket head unit
If you’re using the MS-8 with an aftermarket head unit that has RCA-type outputs, connect the head unit’s
front left and front right outputs to the MS-8’s line inputs 1 and 2 only. Do NOT connect any other head-unit
output signals to the MS-8’s line inputs 3 – 8. During the calibration/setup process, the MS-8 will “normalize”
the input signals and derive as many output signals as your speaker system requires.
IMPORTANT: Do not connect the head unit directly to any ampliers, including a subwoofer amplier. The
MS-8’s signal processing takes nearly 8ms, so any signals connected directly to a head-unit will be ahead
of the signals leaving the MS-8 by about 8ms. This difference will cause them to be out of sync with the
signals that pass through the MS-8. The MS-8 must generate all the signals that are sent to all of the
system’s speakers!
