TONE / RTB Section<br />
SIG PRES<br />
Sets the level at which the Meterbridge Signal Present leds come on for<br />
Channels and 8T's.<br />
It has a range of -35dBu (signal present) to +26dBu (overload).<br />
It has a centre detent which is calibrated to +4dB via a factory-set trim<br />
pot.<br />
RTB<br />
Sets the level for Return Talkback to the M2 speakers.<br />
OSC LEVEL<br />
This has a 3-state operation which can be cycled by pressing the control.<br />
The function is indicated by leds to the left of the knob.<br />
In it's default state (both leds off), it sets the level of TONE, with a range<br />
of -∞ to +16dB.<br />
+4dBu is set roughly at the 12 o'clock mark.<br />
The buttons underneath select the destination of the oscillator or pink<br />
noise to CH, 8T, 2T/MIX and/or LS.<br />
▶ On the 1st press, the CAL led will light.<br />
Instead of the tone level being set by the knob, it is now set via the Trim<br />
Pot on the left of the CAL led.<br />
The trim pot has the same range as the knob, and is factory set to +4dBu.<br />
▶ On the 2nd press, the PNK led will light and pink noise will be<br />
generated instead of sine-wave tone.<br />
The level of the pink noise is set via the Trim Pot to the left of the led, and<br />
is factory set to +4dBu.<br />
▶ The 3rd press turns both of these functions off (both leds off) and the<br />
tone generator returns to it's default state.<br />
NB:<br />
In it's default state, the 2T/MIX button will only send tone to MIX.<br />
If you wish to send tone to the 2T as well, this must be configured in the<br />
Settings screen, by ticking the Osc to 2T option.<br />
CH<br />
Sends tone to the Direct Outputs of all channels.<br />
8T<br />
Sends tone to the 8T Outputs.<br />
