3. When the volume of the amplifier or receiver is
gradually raised, a buzz will be heard from the
speakers. This is pink noise. Set the volume at an
acceptable listening level. At this point, if the level
indicated by the spectrum analyzer is too high, turn
the METER LEVEL knob down bit by bit, and adjust
until all displayed levels are a little above the
center.
Compensating for deficiencies in the Listening
Environment
1. Set the control knobs and switches to the following
positions:
OUTPUT LEVEL control
—
Maximum (10)
EQUALIZER conirols
—
Center (0)
SUBSONIC FILTER switch
—
OFF
EQUALIZER MODE switch
—
DEFEAT
Meter select switches
—
LEFT, RIGHT ON
PINK NOISE switch
—

TAPE monitor switch
—
OFF
2. Press the left EQUALIZER MODE switch to ON.
3. Turn the LEFT meter select switch off. (Equalizing
adjustment is carried out channel by channel with
a final overall adjustment.)
. Start playback through the RIGHT channel. The
spectrum analyzer will indicate the response of
that channel.
. Operate the GRAPHIC EQUALIZER controls for
the RIGHT channel, adjusting them until the
spectrum analyzer display is flat.
. Turn the RIGHT meter select switch off and the
LEFT switch on.
Operate the GRAPHIC EQUALIZER controls for
the LEFT channel,-adjusting them until the
spectrum analyzer display is flat.
. Turn the Meter select switches for both channels
on.
. Start playback through both channels
simultaneously, and recheck and readjust the
spectrum analyzer. This completes the overall
sound enhancement procedure.
