The speaker level controls operate at
all times. If desired, you may adjust
these controls during program material
to fine-tune the balance.
9. Mute: Mutes all output from the
DTT2500 Digital. Press the button once
to mute. Press a second time to restore
audio output.
The CMSS, Dolby Surround, Audio
Mode and Speaker Test buttons are
operable during mute.
Then make sure the speakers are
positioned so that the test sound can
be clearly heard.
Finally, adjust the front panel level
controls for the center, subwoofer and
rear speakers. Adjust each control so
its speaker achieves a balanced
output level with the left and right
satellites (which provide a fixed
“reference” output level).
All Decoder Amplifier functions
except for the level controls are
disabled while the test sound is
running.

Making Connections
Consult the Wiring Diagram on
the next page before making any
connections.
Speaker Connections. Insert one
satellite’s plug into the correspond-
ing Speaker Output on the Decoder
Amplifier. Repeat this process for
the remaining satellites and
subwoofer. If substituting a
powered subwoofer, connect it to
the SUBWOOFER LINE OUT.
Signal Connections.
Dolby Digital. Connect the Dolby
Digital/SPDIF output of your
signal source to the Decoder
Amplifier’s Dolby Digital input
using the cable with the RCA
plugs at each end.
Conventional Digital and Analog
Audio. For Sound Blaster Live!
sound cards with a digital interface
connection card: Connect its
Digital DIN output to the Digital
DIN input with the supplied
Digital DIN cable (the one with the
red plugs at each end). It is not
necessay to to connect a cable to the
Line In and Rear In input in this
instance. Refer to Connection to
Sound Blaster Live! via Digital
DIN for detail of connection. For
all other sound cards: Use tandem
audio signal cable. Connect the
green stereo miniplugs to the Line
Out minijack output of your sound
card and to the Line In minijack
output of the Decoder Amplifier.
Connect the black stereo miniplugs
to the Rear Out minijack output of
your sound card (if present) and to
the Rear In minijack input of the
Decoder Amplifier.)
Power Supply Adapter Connec-
tions. Confirm the power switch is
in the “OFF” position. Insert the
power supply’s AC plug into an
appropriate receptacle. Insert the
small DC connector into the “15V
DC IN” receptacle on the back of
the Decoder Amplifier.
Hook and Loop Fasteners: When
mounting speakers with hook and
loop fasteners, make sure that all
surfaces are clean and free of dirt
and grease. Hard, flat, unpainted
surfaces work best with hook and
loop fasteners (see Diagram Q).
Attach the fastener to the speaker
first, remove the backing and adhere
to the chosen surface.
The Decoder Amplifier can be placed on
the desktop, a shelf or any site that makes
the controls convenient.
The Power Adapter cord must be
able to reach from the Decoder Amplifier
back panel to your AC power receptacle.
Place the Decoder Amplifier on a hard,
flat surface.
There are ventilation slots on the bottom
and top of the Decoder Amplifier’s
enclosure. Don’t block the ventilation slots
by placing material on top of or below the
Decoder Amplifier.
