Results = 7.0 Hz, 7.0 Hz, 7.0 Hz, 7.0 Hz
(7) Channel Balance
Record simulated 1000 Hz ½ reference level data for each channel 1,2,3 and 4 and
verify amplitude all within 3 dB.
Record simulated 1000 Hz 1/10 reference level data for each channel 1,2,3 and 4
and verify amplitude all within 3 dB.
Example report message(s):
08:04:52 PASSED Channel Bal 1000 Hz 0.5 ref (All within 3 dB except HQC)
Results = HQ1 5.2 /HQ2 5.3 /HQ3 5.1 /HQC 5.1 /SQV1 5.0 /SQV2 5.4 /SQV3
5.4 /SQC −56.6 dBV
08:05:40 PASSED Channel Bal 1000 Hz 0.1 ref (All within 3 dB except HQC)
Results = HQ1 −8.3 /HQ2 −8.2 /HQ3 −8.4 /HQC −9.4 /SQV1 −8.0 /SQV2 −8.1
/SQV3 −8.1 /SQC −293.8 dBV
(8) Frequency Response
