1.4 Change both input sensitivity switches
to the 100 mV position.
1.5 The output should be 1 Volt rms,
(+20 dB
± 2 dB).
2. Music Channel Response Tests
2.1 Return both input sensitivity switches
to the 1 Volt position.
2.2 Apply a 1 Volt rms, 1 kHz signal to
both A and B inputs.
2.3 Reference a dB meter to the left or
right output, and perform the tests listed in
the 102 System Controller Frequency
Response table below.

3. Channel Separation Test
3.1 Apply a 5 Volt rms, 1 kHz signal to the
channel A and B inputs.
3.2 Reference a dB meter to the channel
A output.
3.3 Remove the applied signal from
channel A.
3.4 The output should be > 50 dB down at
channel A.
3.5 Sweep the signal generator from
80 Hz to 13 kHz at 1 Volt rms.

3.6 The output should be > 50 dB down
at channel A.
3.7 Return the signal to channel A.
3.8 Repeat steps 3.2 thru 3.7 for
channel B.
4. Maximum Output Test
4.1 Apply an 8 Volt rms, 1 kHz signal to
the channel A and B inputs.
4.2 The output should be 8 Volts rms
for both channels. (0 dB ± 2 dB)
5. Distortion Test
5.1 Apply a 1 Volt rms, 1 kHz signal to
the channel A and B inputs.
5.2 The distortion should be < .1% at both
the channel A and B outputs.
5.3 Reduce the input signal to .5 Volt rms
and sweep the generator from 80 Hz to
12 kHz, measuring the distortion at
various frequencies.
5.3 The distortion should be < .1 % at
both the channel A and B outputs.
6. Mute Test
6.1 Set the Voice Input Switch to the MIC
position.
6.2 Apply a 1 Volt rms, 1 kHz signal to the
channel A and B inputs.
6.3 Reference a dB meter to the channel
A or B output.
6.4 Take another signal line from the
generator, or any other line level output
signal, and quickly add and remove the
signal to the positive (+) input terminal of
the voice channel.
