TEST PROCEDURES
2.11 Apply an in-phase, 50 mV, 1 kHz signal
to the left and right music audio inputs at J6.
2.12 Measure the small signal distortion
level at the center channel speaker output
at J13 pins 1 and 2. It should be < 0.5%
THD+N.
2.13 Apply an in-phase, 600 mV, 1 kHz
signal to the left and right music audio
inputs at J6.
2.14 Measure the large signal distortion
level at the center channel speaker output
at J13 pins 1 and 2. It should be < 0.2%
THD+N.
2.15 Apply an in-phase, 1.8 Vrms, 1 kHz
signal to the left and right music audio
inputs at J6.
2.16 Measure the compressor signal distor-
tion level at the center channel speaker
output at J13 pins 1 and 2. It should be
< 2.0% THD+N.
3. Surround Channel Audio Tests
3.1 Set up the amplifier under test as out-
lined in the test setup.
3.2 Apply a L= -R, 100 mV, 1 kHz signal to
the left and right music audio inputs at J6.
You can do this by inverting the phase of the
right channel input signal from the signal
generator.
3.3 Reference a dB meter to the input level.
3.4 Measure the output level at the left and
right surround channel speaker outputs at
J14. It should be +34.5 dB + 1.5 dB.
3.5 Apply a L= -R, 100 mV, 200 Hz signal to
the left and right music audio inputs at J6.
3.6 Reference a dB meter to the input level.
3.7 Measure the output level at the left and
right surround channel speaker outputs at
J14. It should be +36.9 dB + 1.5 dB.
3.8 Apply a L= -R, 100 mV, 12 kHz signal to
the left and right music audio inputs at J6.
3.9 Reference a dB meter to the input level.
3.10 Measure the output level at the left and
right surround channel speaker outputs at
J14. It should be +39.2 dB + 1.5 dB.
3.11 Apply a L= -R, 50 mV, 1 kHz signal to
the left and right music audio inputs at J6.
3.12 Measure the small signal distortion
level at the left and right surround channel
speaker outputs at J14. It should be
< 0.5% THD+N.
3.13 Apply a L= -R, 600 mV, 1 kHz signal to
the left and right music audio inputs at J6.
3.14 Measure the large signal distortion
level at the left and right surround channel
speaker output at J14. It should be < 0.2%
THD+N.
3.15 Apply a L= -R, 1.8 Vrms, 1 kHz signal
to the left and right music audio inputs at J6.
3.16 Measure the compressor signal distor-
tion level at the left and right surround chan-
nel speaker output at J14. It should be
< 2.0% THD+N.
4. Bass Channel Audio Tests
4.1 Set up the amplifier under test as out-
lined in the test setup.
4.2 Apply an in-phase, 100 mV, 100 Hz
signal to the left and right music audio inputs
at J6.
4.3 Reference a dB meter to the input level.
