The first model of the DM-6 had on DB25 connector wired for the DTS
system.
The first production run of the DM6 has one DB25
connector on the rear panel. This may be used for
either the DTS or DA20 connection (with the ap-
propriate cable) although the labeling on the front
panel pushbuttons indicates this input as the DTS.
The other digital input is labeled DIG on the front
panel pushbuttons. If both DTS and DA20 proces-
sors are being used on the same DM6, the the DA20
will have to be wired to the input terminal strip on
the DM6 while the DTS will plug into the DB25.
The second production run has an additional DB25
socket on the back of the p[roduct so that plugging
in both the DTS and the DA20 simultaneously will
be possible without having to wire directly to the
terminal strips.
The current models have two DB25 connectors. One is wired for
the DTS system and the other is for the Dolby DA20.
The DTS system is active when the front panel DTS button is lit. The
Dolby DA20 is active when the DIGITAL light is lit. TRhe OPTICAL
button may be pressed to return to the backup optical soundtrack
when necessary.
Additional digital inputs are provided for other systems. The signals
are connected to the individual terminals of the barrier strip. The
DB25 for the DA20 is wired in parallel with the input terminal strips.
Now wire the digital processor outputs and control
lines to the appropriate inputs on the rear of the
DM-6. If you are using the DTS System and have
ordered the DTS to DM-6 cable from SMART, it is
only necessary to plug the cable in, and all con-
nections are made for you. This cable, DM6-DTS,
has a DB50 plug on one end which plugs into the
mating connector on the DTS. The other end has a
DB25 plug which plugs into the DB25 receptacle
on the rear of the DM-6.
If you are wiring a Dolby DA20, connections will
be made to either the DIGITAL INPUTS terminals
on the bottom right terminal strip or to the DB25
connector on the rear of the DM-6. The 2 DA20
cable sets are configured as follows:
