DCM Speakers DCM TF625 User Manual

DCM In-Wall Loudspeakers are designed to work within any interior decorating
scheme. They can be installed in virtually any location where flush mounting is
possible. To maximize their sound performance however certain guidelines
should be followed.  For the best stereo reproduction the two loudspeakers
should be placed an equal distance from your listening position and separated so
that the angle between them, at the listening position, is between 40 and 60
degrees. For best stereo imaging, we recommend that the units be placed so that
the tweeters are as close as possible to the ear level of a seated listener. For
normal installation, follow steps 1 through 6.

If installing as part of new construction, the included hole provider may be used
for an easy, accurate installation. The hole provider is pre-assembled with 24”
straps for mounting to studs and has a convenient speaker wire holder for pre-
wiring. Once the walls are finished (drywall, paint, etc.) the mounting holes can be
cut-out using the hole provider as a template for saws with guide bearings or sim-
ilar blades or drill bits. Follow steps 4 through 6 to complete installation.

The IR knockout is located next to the voice control on the loudspeaker baffle. It
is designed to be used with standard infra-red receivers with 1/2” diameter shafts.
The knockout can easily be removed using a standard screwdriver. Place the
screwdriver head on the back side of the knockout, then tap on the screwdriver
with the palm of your hand, The knockout will break away at the perforation. The
IR receiver can then be threaded through the knockout hole.

Once the loudspeakers are placed in the listening room, the TF625 can be adjust-
ed to compensate for speaker placement. The TF625 is designed to produce the
smoothest frequency response on axis. If the speaker is mounted off axis (hori-
zontal or vertical), the tweeter can be pivoted towards the listening position to
restore high frequency performance. The voice control can then be adjusted to
optimize vocal reproduction that may have been affected by mounting location.
The voice control is continuously variable and can be fine tuned to boost or cut
vocal energy as desired.
