3.2.6 Test Tone Buttons

These buttons serve the same purpose as those on a 1788A. You can put up a -20dB or 0dB tone on any channel of the unit that is selected.

Putting Up a Test Tone

While holding down either the -20dB or 0dB Tone button, press any Channel Select button. The chosen tone level will be sent from that channel’s audio outputs (analog and digital). You can’t group-select tones, but you can sequentially press Channel Selects to run up more channels while holding down the Tone button.

To defeat the tone, press either Tone button again. The tone(s) will instantly (but clicklessly) revert back to the mic inputs.

Secondary Functions

The Tone buttons also serve to provide secondary (hidden) functions like display brightness control, display of the firmware version, and Clip/Limit light holdover time. Table 3-3 shows the secondary functions.
