68. SIGNAL GENERATOR / PINK NOISE
Press to select either pink noise (1KHz/ PINK switch pressed
in) or a 1kHz sine wave tone (1KHz/ PINK switch up position)
as the test source. Start with the OSC/NOISE trim control fully
turned down. The generator ON switch is pressed to activate
operation. The yellow indicator LED lights to warn that the
generator is enabled.
The generator signal is routed to any source selected on the
switch bank above the TALK ON switch. Use the signal to test
the loudspeaker system and line up connected equipment.
Pink noise is useful for quickly testing the full range frequency
operation and phasing/polarity of loudspeakers. The 1kHz tone
is best suited to lining up equipment with its steady reading on
the meters.
