192 I/O Guide26

When you have properly aligned the incoming

peak signal levels to match the calibration refer-

ence level, both Automatch indicator arrows

will light: the up arrow red and the down arrow

blue.

Above the fader is a peak volume indicator. This

indicator will show the dB level above and be-

low your chosen headroom value. If the peak in-

dicator is showing –19.1, you are –1.1 dB below

a headroom value of –18 dB. If the display is

showing –16.5, you are +1.5

dB above your

headroom value of –

18 dB.

Calibration Mode.

Calibrating a System with Both

192 I/O and 96 I/O Audio

Interfaces

The “A” trim on the192 I/O is factory preset

with 18 dB of headroom in its +4 dB line level

operating mode. The 96 I/O, however, is fixed at

14 dB of headroom and its inputs are not adjust-

able.

When setting up a 96 I/O (particularly in sys-

tems using a combination of the 192 I/O and

96 I/Os), it may make sense to calibrate all I/Os

for –14 dB headroom. This helps ensure that re-

corded audio files have the same relative levels

regardless of which interface is used for record-

ing.
