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.
For Sound Blaster Live! sound
cards with a digital I/O 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 necessary 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 (next page) for
more information about this
connection.
For all other sound cards: Use the
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 first to a

speaker.  Then remove the
remaining 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 (see Diagram R).

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.
