The playback signal should be displayed on the Software Return and Mixer Master’s meters.
5 Use the Software Return and Input faders to balance between the input and playback signals.
6 If you’ve found a good balance but the Mixer Master’s Over LEDs light, reduce the Mixer Master fader.
Pro Tools IO Control Low Latency Mixing
A bit of background information concerning latency and computer-based digital recording setups will help you better understand
these functions.
When recording with most computer-based digital audio applications, the delay between the input and output of the recording sys-
tem often disturbs the timing of the musicians performing. This delay, known as latency, means that the musician hears the notes
played a few milliseconds after having actually played them. As anyone who has spoken on a phone call with echo knows, rela-
tively short delays can confuse the timing of any conversation, spoken or musical.
