AUDIO CONNECTIONS
The M8 has three audio inputs: Line IN, BUS IN and AUX IN. The
assignment of these inputs provides a wide range of design
exibility for almost any multiroom or multizone audio ap-
plication.
Note: All examples are stereo unless otherwise noted.
Line IN (Diagram 10)
Eight, line level audio inputs allow direct channel connection
of up to eight mono sources or four stereo sources. They are
best used for stereo amplication of zone outputs from a mul-
tizone controller or for amplication of a stereo source that
is to be fed to a dedicated pair of speakers. Also see: System
Applications/Multizone Mixed Use
1. Using a stereo RCA patch cable with gold ends, connect
the L & R line level audio OUT of an audio source to a
channel pair (1/2, 3/4, 5/6, 7/8) of Line INs on the M8. Odd
number channels (1, 3, 5, 7) are left, even number chan-
nels (2, 4, 6, 8) are right.
2. Set the Bridged switch for the channels used in Step 1 to
OFF.
3. Set the Channel Input switches for the channels used in
Step 1 to LINE.
4. Connect the speakers for this source to the Speaker termi-
nals with the same numbers as the channels used in Step
1. Use the Normal Mode conguration as described in
section: Normal Mode Speaker Connections.
Note: Use of a volume control is optional depending upon
system design (multiroom vs multizone).
5. Repeat Steps 1-4 for all other audio sources using Line IN
connections.
BUS IN/BUS LOOP (Diagram 11)
BUS IN is ideal for distributing mono or stereo si
gnals to mul-
tiple output channels. BUS IN can feed up to eight mono or
four stereo outputs. Line level audio connected to BUS L IN will
feed to any channel set to BUS L and line level audio connec
t-
ed to BUS R IN will feed to any channel set to BUS R. The BUS IN
signal will also output as a xed line level audio signal via the
BUS LOOP, which can then be connected to up to four addi-
tional M8 BUS IN’s for up to twenty rooms of amplied audio.
