Note on microphone and gain input gain:
The VXpocket 440 has three input gains: 0dB, +30 dB, and +48 dB. 0 dB is the
line gain, +30 dB and + 48 dB are the microphone gains.
For a gain of 0 dB, a +10 dBu maximum input signal gives 0dBfs (digital full
scale).
For a gain of +30 dB, a – 20 dBu maximum signal gives 0dBfs (digital full scale).
For a gain of +48 dB, a – 38 dBu maximum signal gives 0dBfs (digital full scale).
Let N be the nominal input level, and H the input headroom.
N and H values must be set so that: N + H
≤
maximum input level.
The following must be done to switch the input to microphone gain:
* N + H = - 38,
* if the fader Analog In

Analog In is set to a gain higher or equal to 0 dB, the micro gain is
+48 dB.

Analog In balance fader should not be used in microphone gain mode, as
this would modify the microphone gain value.
