Pre-Out
When configuring the M80 as a 7.1 or 5.1 surround system, connect the Pre-Out S/W (Subwoofer) jack to the LFE or line level input
on a powered subwoofer as shown in
Diagram 7
on
Page 24
and described on
Page 25
. (Required for 5.1 or 7.1 configuration.)
Connect the remaining Pre-Out jacks on the M80 Rear Panel to an external amplifier for high output audio in large rooms or when
using speaker systems that require additional power. (Option)
7.1 System
1.
Using a 7.1 audio patch cable (eight RCA-RCA plugs; or 4 identical stereo RCA-RCA patch cables) with gold ends, connect
the PRE-OUT jacks on the M80 to the appropriate line level audio INs on the external amplifier(s). (A proper 7.1 Cable will
have color coded RCA plugs that match the color coding on the PRE-OUT jacks.)
2.
Do not connect the S/W Out on the M80 to the amplifier unless the amp is going to power the subwoofer.
3.
Confirm proper connection of audio channels from the M80 to the amplifier(s). Improper connections will have an ad-
verse effect on surround sound performance.
4.
Connect the external amplifier(s) to speakers as appropriate.
5.1 System
1.
Using a 5.1 audio patch cable (six RCA-RCA plugs; or 3 identical stereo RCA-RCA patch cables) with gold ends, connect the
PRE-OUT jacks on the M80 to the appropriate line level audio INs on the external amplifier(s), and do not connect the BSR
(Surround Back Right) and BSL (Surround Back Left) Out jacks on the M80 to the amplifier. (A proper 5.1 Cable will have
color coded RCA plugs that match the color coding on the PRE-OUT jacks.)
2.
Do not connect the S/W Out on the M80 to the amplifier unless the amp is going to power the subwoofer.
3.
Confirm proper connection of audio channels. Improper connections will have an adverse effect on surround sound per-
formance.
4.
Connect the external amplifier(s) to speakers as appropriate.
