typically is where you want to set your 0VU reference, or average operating level of all
following equipment.
The Gain indicators in the individual channel status readout are used to show when the
channel is in a test tone mode with a blinking bar. When the test tone is activated, it is
not possible to adjust the input gain on the channel being tested. Also, the MicLim™ and
26dB PAD functions are defeated.
Starting and Stopping the Test Tone
1. Put the 1788A in Local Control.
2. Hold down either the -20dBfs or 0dBfs button at the same time as you press the
CHANNEL SELECT button(s) of the channel or channels you wish to test.
When the test tone is activated the two test tone buttons will start flashing.
To deactivate the test tone, press either one of the two test tone buttons
again.
