Controlling Delay (Latency) During Monitoring
Mbox 2 and Pro Tools LE use your computer for
all audio processing, playback, and recording.
This causes a small amount of audio delay, or la-
tency.
Latency is most obvious when monitoring dur-
ing recording. You may hear this as a slight de-
lay between when you produce the sound and
when you hear the sound through the speakers
or headphones.
Mbox 2 gives you the ability to monitor your
analog input signals while recording, without
hearing any latency. This zero-latency analog
monitoring is controlled by the Mbox 2 front
panel Mix control, which you can use to blend
and adjust the ratio between the Mbox 2 analog
input and Pro Tools playback.
To use zero latency monitoring while recording:
1 Launch Pro Tools and set up a session.
2 Do one of the following:
• Mute the track you are recording on. This
prevents you from hearing the delayed sig-
nal coming back from Pro Tools through
the Mbox 2.
– or –
• Use the Mix control on the front of the
Mbox 2 to blend the playback tracks with
the analog tracks that you are recording.
