Monitoring PPMs
Set audio levels so that audio peaks average at the nominal 0vu point indicated below on the PPM
meters. This represents a program level of +4 dBu leaving the codec. Audio peaks can safely reach
+22 dBu without clipping, providing 18dBu of headroom from the nominal 0vu point. Note: the audio
metering reference scale is automatically adjusted by default when a Merlin codec connects to a
Commander G3 codec. The G3 metering scale is between -11dBu and +18dBu.
Mono and Stereo PPM Metering
When connected with a mono program the codec will display a mix of inputs 1 and 2 on
PPM1
.
PPM 3
displays the level of return audio.
When connecting with a stereo program, the codec displays audio on
PPM1
and
2
for inputs 1
and 2 and
PPM 3
and
4
for the return audio.
