TEST PROCEDURES
9. Center Channel Frequency Response
9.1 Apply a 2.5kHz, 50mVrms signal to the
left and right inputs (in phase).
9.2 Reference a dB meter to the center
channel output.
9.3 Measure the center channel output
according to the following table.
FREQUENCY RESPONSE
7. Bass Channel
7.1 Apply a 100Hz, 30mVrms signal to the
left and right inputs (in phase).
7.2 Reference a dB meter to the bass
channel output. Measure the bass channel
output according to the following table.
Frequency Output Tolerence
20Hz -17.0dB ± 3.0dB
35Hz +6.9dB ± 2.0dB

10. Surround Channel Frequency
Response
10.1 Apply a 2.5kHz, 50mVrms signal to
the left and right inputs (out of phase).
10.2 Reference a dB meter to the surround
channel output.
10.3 Measure the surround channel output
according to the following table.
8. Left, Right Channel Frequency Re-
sponse
8.1
Apply a 2.5kHz, 100mVrms signal to
the left or right channel only.
8.2 Reference a dB meter to the output of
the same channel as the applied signal in
8.1.
8.3 Measure the left or right channel output
according to the following table.
Note: Perform this test for both channels.
