It is possible the performer may prefer to hear a monitor mix of voice and instruments adjusted 

to their particular taste. Focusrite Control lets you define a custom monitor mix for the artist and 

this mix may include the current input signals as well as previously recorded DAW tracks. You can 

easily route a musician’s stereo monitor mix to Outputs 3 and 4, and it will then be available at the  

Clarett 2Pre USB’s headphone socket. If you need to send the monitor mix to more than one musician, 

you can use the rear panel line outputs to send the mix to a headphone amplifier.

When sourcing monitor mixes from input signals in this way, ensure the DAW channels you are 

recording are muted, otherwise the musicians will hear themselves “twice”, with one signal audibly 

delayed as an echo.

Please refer to the Focusrite Control User Guide for more details on setting up monitor mixes.

A note about latency
You will probably have heard the term “latency” used in connection with digital audio systems. In the 

DAW recording application described above, latency is the time it takes for your input signals to pass 

through your computer and audio software, and back to you.

While not an issue for most recording situations, latency can be a problem for a performer who 

wishes to record while monitoring their input signals. This might be the case if you need to increase 

your buffer size, which could be needed when you record overdubs on a large project using many 

DAW tracks, software instruments and FX plug-ins.

Common symptoms of a buffer setting that is too low could be glitching audio (clicks and pops), or a 

particularly high CPU load within your DAW (most DAWs have CPU readouts). If you experience this 

on a  Mac, you can raise the buffer size from the DAW application itself; on a Windows PC you will 

need to change this from the 

ASIO ControlPanel

 which can usually be accessed from your DAW 

Setup Preferences

*.

The Clarett 2Pre, in conjunction with 

Focusrite Control

, allows “low latency monitoring”, which 

overcomes this problem. You can route your input signals directly to the Clarett 2Pre’s headphone 

and line outputs. This enables the musicians to hear themselves with ultra-low latency – i.e., 

effectively in “real time” – along with computer playback. The input signals to the computer are not 

affected in any way by this setting. However, note that any effects being added to the live instruments 

by software plug-ins will not be heard in the headphones in this case, although the FX will still be 

present on the recording.
