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-Qi11IJal‘I--’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.
