CONNECTIONS & SETUP
AUX IN (Stereo)
1. Using a stereo RCA patch cable with gold ends, connect
the L & R line level audio OUT of an audio source to the
AUX IN Left and Right inputs on the M8.
2. Set the Channel Input switches for the channels that are
to output the stereo source connected to AUX IN to AUX
L and AUX R. Set the switches for stereo channel pair (1/2,
3/4, 5/6, 7/8) as AUX L (1, 3, 5, 7) and AUX R (2, 4, 6, 8).
3. Set the Bridged switches for the channels used in Step 2
to OFF.
4. Connect the speakers that are to play the source con-
nected to AUX IN to the Speaker terminals with the same
numbers as
the channels used in Step 2. Use the Normal
Mode conguration as described in section: Normal
Mode Speaker Connections.
Note: A volume control will typically be required for indi-
vidual room volume in th
is application.
BRIDGED MODE CONNECTIONS (Diagram 13)
When high power output is required for a particular source,
two adjacent channels (1/2, 3/4, 5/6, 7/8) can be ‘bridged’ to
create a single high power channel. Two bridged channel pair
can then be used for stereo high power output. Also see: Sys-

Diagram 13 M8 Bridged Mode Audio Input Connections
For example of bridged channel source connections, Channels 5-8 (same as those used in the bridged speaker connection dia-
grams) will be used to connect a stereo device to two bridged channel pair.
1. Using a stereo RCA patch cable with gold ends, connect the L & R line level audio OUT of an audio source to the odd number
(1, 3, 5, 7) Line INs on the M8. Use channels 1, 5 for left, use channels 3, 7 for right. In Diagram 13, Channel 5 is left, Channel 7
is right.
2. Set the Bridged switches for the channels used in Step 1 (5/6, 7/8) to ON.
3. Set the Channel Input switches for the channels used in Step 1 (Channels
5/6, 7/8) to LINE.
4. Connect the speakers for this source to the bridged channel Speaker terminals with the same numbers as the channels used
in Step 1 (5/6, 7/8). Use the Bridged M
ode conguration as described in section: Bridged Mode Speaker Connections.
Note: Volume control is optional depending upon system design.
5. Repeat Steps 1-4 to connect another source in bridged high power mode.
CAUTION! Regardless of conguration follow the connection instructions for normal and bridged power carefully. Failure to do so
can cause severe damage to the M8 and speakers. The Procient Warranty does not cover this type of damage.
