Operation
Normally, there is no operator intervention required
to use the DM-6 except to initially set the volume
and to manually go to bypass during certain types
of failures. The DM-6 is running under the com-
mand of the digital processor, and changes between
digital mode and optical stereo are initiated by the
digital processor. If the digital processor no longer
sees a valid digital signal or timecode, then it will
tell the DM-6 to go to Optical mode. If the digital
processor or DM-6 fails but does NOT automati-
cally go into optical mode, then the operator needs
to push the optical button on the DM-6 front panel.
If this still does not correct the problem, then the
operator must throw the toggle switch on the DM-6
front panel to the bypass position. This will force
the DM-6 into optical mode regardless of what the
lighted pushbuttons are telling you.
Installation
Locate the DM-6 close to the stereo processor and
the digital processor. There are 3 cable sets which
may be ordered with the DM6. One cable set is for
connecting the DTS digital system to the DM6, and
the other 2 are for the Dolby DA20.These cables
are about 30 inches long, so keep this in mind when
selecting a location. Also install any additional
power amps if needed at this time (e.g., for split
surrounds). The existing rack wiring harness may
have to be extended or re-wired to accomodate the
locations of the processors and to make new con-
nections for any new amps. Install the power sup-
ply in the bottom of the rack and bring the power
supply wiring harness up to the top left terminals
The input card has two sets of input level controls for each
of two digital sources. This allows you to match the levels
between the players

on the DM-6. Please note that the Plus Voltage lead
is red, the Minus Voltage lead is yellow, and the
Ground lead is black. Do not connect the leads in-
correctly as damage could result !
Disconnect the outputs from the stereo processor
which go to the power amp inputs. These leads to
the power amps will now connect to the output ter-
minals of the DM-6. Add any new leads as needed
for additional power amps.
Make a new wiring harness which will connect the
outputs of the stereo processor to the OPTICAL IN-
PUTS on the top left terminal strip on the rear of the
DM-6. Please observe standard wiring practice, i.e.,
use 2 con shield cable and ground the
shield at one end only.
