POWER CONNECTORS
/
LED
P
0 WER INDICATOR
Your amplifier (except D60) is equipped with an LED (+i
:
),
which glows when
power is applied to the amplifier. Since power should be disconnected
dunng
installation, these LED should be dark until you are finrsned. The LED
will
go out if
either the power-lrne fuse or the internal fuse is blown.
INPUT LEVEL ADJUSTMENT
Left- and right-channel input fevels are adjusted by
con?rols
(HO) and
(#12),
re-
spectively. These controls can be turned with a
sm-11
‘I-’
Qi
IJal-head
screwdriver. Begin
by turning both level controls to
mM-num
(full
counterclcckwise).
Turn the system
on, and set the volume control on your tuner/deck a! its mid-pair& Advance the
amplifier input level
controfs
until you have reached a comfortable listening level
and both channels are in balance.
NOTE: With many tuner/decks, the radio output level is significantly different than
the tape output level. Check both sources, and set
leve!s
using the lesser of the
outputs (usually the tape).
PROTECTION CIRCUITS
Your amplifier is protected against both overheating and short circuits.
If your amplifier shuts down, turn off the system, wait for a few minutes, and turn
the system on again. If the amplifier does not come on again:
Check
the loudspeaker wires for
shorts
using
an
ohmmeter or continu-
ity checker.
*Check
the LED indicator. If it is out, check the fuse in the power line;
if that fuse is blown, replace it with another fuse of identical type and
value and try again.
*If the power line fuse is not blown, check the internal fuse. If blown,
replace with the identical type and value. If the fuse blows again, call
your Soundstream Dealer for service.
If the
amplifier continually shuts down because of overheating, the unit may have
inadequate ventilation. (See Location andMounting
section
on Page 3).
BRIDGING THE AMP TO MONO
The D-200,0100,
D60.
Class-A-50 and Class-A-40 amplifiers can be bridged to
deliver high
power into a single channel. (Refer to the Specifications listing at the
end of this manual for power ratings.)
Bridging requires a simple internal adjustment. Consult your authorized
Sound-
stream dealer if you wish to bridge your amplifier.
