CONNECTIONS & SETUP
LEVEL CONTROL
The Level Controls on the M8 allow adjusting the audio level of
each channel. The adjustments can be made as mono channels,
normal stereo pair or bridged pair.
The Level Controls can be used to balance overall system levels
so audio is consistent from room to room. This can help compen-
sate for dierences in acoustics for dierent rooms, given how
each room is nished (hard vs soft surfaces) or speaker eciency
if dierent models or speaker types are used in dierent rooms.
The Level Controls are also aective for setting a maximum out-
put level for a given room or speaker. This will help prevent the
amp from clipping and also protect the speakers from damage
by being driven to improper levels.
The L
evel Controls can also be used to balance stereo audio
when the speakers placement is less than ideal. See section:
Speaker Placement for additional information.
Level Control
Before setting Level Controls be sur
e all connections are correct
and have been conrmed prior to powering up the system.
1. With the system OFF, set the M8 Level Controls to the center
detente (click) position.
If using individual room volume controls, turn the volume
controls all the way up, (clockwise/right).
Turn the master volume, (receiver, zone controller, etc) all
the way down.
2. Turn the system ON and play a source (CD, Tuner, etc.)
3. To adjust M8 Level Controls, turn the knobs counterclock-
wise (left) to reduce level. Turn the knobs clockwise (right) to
increase level.

gram 19, (Normal Mode), Channel 1 is left, Channel 2 is right. For stereo applications in Bridged Mode, adjustments are made
using the odd numbered channels of the bridged pair. In Diagram 20, (Bridged Mode), Channel 5 is left, Channel 7 is right.
4. Slowly raise the master volume on the receiver or zone controller until audio is playing through the M8 at a moderate level.
Conrm audio output from all connected speakers.
5. Alternately using the master volume control on the receiver or zone controller and M8 Level Controls, in small steps, continue
to raise the master volume and make adjustments to the M8 Level Controls to set a maximum output level for a given speak-
er/pair. Check each speaker/pair as master volume is raised to monitor output level and distortion. Be careful not to damage
the M8 or speakers.
Note: Once max level has been set the actual listening level will be reduced when adjusting the individual room volume con-
trols.
6. Reduce individual volume control levels to normal listening levels.
7. Leave the master volume control on the receiver or zone controller set to the level used while setting the Level Controls.
