Option 40
XLR connectors must be wired
to current AES recommenda-

NOTE. Before performing the level accuracy procedure, Verify the sine-wave
generator level at 120 Hz by measuring with an accurate AC voltmeter such as a
HP 3458A Digital Voltmeter. You may also use an AC voltage calibrator such as
a Fluke 5700A for this measurement. Verify that the sine-wave generator can
meet the amplitude accuracy specifications listed in Table B-1.
