A stereo source connected to BUS IN Left & Right will be fed to any M8 channel pair (1/2, 3/4, 5/6, 7/8) with the Channel Input switches set to BUS L and BUS R. A mono source connected to either the BUS L or BUS R IN can be fed to any channel by setting the Channel Input switch to BUS L or BUS R. - Page 8 13. 12V DC CONTROL OUT - (One 3.5mm mini jack) Connect to the 12V DC Control Input on a device that is to be synced to M8 ON/OFF status. When the M8 turns ON, (Manual, Auto ON or Trigger) the 12V DC Control Out will output 12 V DC that can be used to activate a DC voltage controlled device.

Closed spaces such as equipment cabinets and racks can get hot with the heat generated by microprocessors and motors in vari- ous devices. Providing proper ventilation for good air flow will help keep the temperature down and protect not only the M8 but all system components and help preserve their longevity. -

INSTALLATION Video Display Front Front Left Right A=B=C Ideal Listening Zone Diagram 4 Speaker Placement SPEAKER PLACEMENT Use the following recommendations when determining speaker placement. Determine The Ideal Listening Zone The area where the user will most likely be sitting when listening to the speakers is the Ideal Listening Zone. Placement of Stereo Speakers The distance between the left and right speakers should as closely equal the distance from one speaker to the listener as pos- sible. -
Page 11: Wire Requirements
Connecting the M8 for multiroom audio requires that two pair of speaker wire be run from the M8 location to each volume control in home runs (each run direct from the M8 to each volume control). One additional pair of speaker wires will then be run from each volume control to each of the speakers that will be controlled by that volume control. -
Page 12: Speaker Connections
CAUTION! Regardless of configuration follow the connection instructions for normal and bridged power carefully. Failure to Volume do so can cause severe damage to the M8 and speakers.

Bus Loop The M8 BUS LOOP is a fixed line level audio output that can be used in a number of different ways. In the example shown, the BUS LOOP is being fed back to the M40 Receiver Main IN. The M40 features a pre-out/main in connection for various purposes. In this case, that connection will be used to insert the M8 into the source audio signal path. - Page 22 VCS60 VCS60 VCS60 Volume Volume Volume Volume Control Control Control Control Pro cient C645 Ceiling Speakers Pro cient C645 Ceiling Speakers Pro cient C645 Ceiling Speakers Pro cient C645 Ceiling Speakers Diagram 22 M8 Home Theater Plus Second Zone System...
