1. Page Input To Page Output Gain
1.1 Apply a 5 Vrms, 1KHz signal to the
Page Input.
1.2 Measure the Page Output. Should be
4.22 Vrms (+ .78 Vrms/ - .67 Vrms).
2. Page Input To Line Outputs Gain
2.1 Apply a 5 Vrms, 1KHz signal to the
Page Input.
2.2 Measure the left and right Line Output.
Should be 4.22 Vrms (+1.09 Vrms/ -.87
Vrms).
3. Music Input A to Line Outputs Gain
3.1 Apply a 500mV rms, 1KHz signal to the
Music A left and right input.
3.2 Measure the left and right Line outputs.
Should be 4.47 Vrms (+.84 Vrms/ - .71
Vrms).
Note: Repeat this test for Music Input B.
To select Music Input B, short the remote
select input.
4. Music Input A to Speaker Outputs Gain
4.1 Apply a 10 mVrms, 2KHz signal to the
left and right Music A input.
4.2 Measure the Speaker output. Should be
290 mVrms (+54mVrms/ - 46mVrms).
5. Frequency Response
5.1 Apply a 10 mVrms, 2KHz signal to the
left and right Music A Input.
5.2 Reference a dB meter to the Speaker
output and set level to 0 dBr.
5.3 Change the signal to 12.5 KHz.
5.4 Measure the left and right Speaker
output. Should be 5.1 dBr (
