SUBJECT

peared in the July issue of STAR*TECH Journal, we recommend the following procedure. By
the way, the song Thunder Rolls by Garth Brooks suggested by Bill in his article is a good choice .

1. Make sure that the phono-
graph and extension speakers
are connected to the proper
speaker taps.
2. On the amplifier, set all
seven RIGHT CHANNEL and
all seven LEFT CHANNEL
graphic equalizer controls
fully counter-clockwise.
3. Set the volume control fully
clockwise (maximum volume)
and make a selection.
4. While the music is playing,
if
the
OVERLOAD
INDICATORS(S) stay OFF to
occasionally flicker in a ran-
dom manner the load is accept-
able.
If
the
OVERLOAD
INDICATOR(S) are always lit
or flicker continuously, the
amplifier is overloaded and
you must perform Step 5.
5. Do this step only if the
OVERLOAD INDICATOR(S)
came on as described in the
previous step. Find the source
of the overload (shorted
speaker wires, too many
speakers connected, or
speaker power taps too high).
After you fix the short, discon-
nect a few speakers, or lower
the speaker power tap selec-
tion; repeat Step 4.
