Mon Out (Monitor Output)
These outputs support balanced TRS, or unbal-
anced TS, 1/4-inch connections. To monitor 
your mix, these outputs can be connected to a 
mixing board, directly to a monitoring system 
such as a stereo power amp, or another stereo 
destination.
The Mon Out Left and Right play the audio that 
is routed to analog outputs 1 and 2 from within 
Pro Tools, respectively. These analog outputs 
feature 24-bit digital-to-analog converters.
Input 1 and Input 2
Each analog source input channel (Input 1 and 
Input 2) provides Mic, DI (“Direct Inject”), and 
Line (TRS) ports. These balanced/unbalanced 
analog audio inputs support a broad range of in-
put levels, as follows:
• Mic (microphone) for XLR inputs
• Line (TRS) for line level signals on TRS or TS 
inputs
• DI for other 1/4-inch TRS or TS connec-
tions
On the front panel, the input signal is adjusted 
by the Gain control for each channel and the 
source (Mic/Line, or DI) is chosen using the 
Source selectors. 
Source 2 is at the far left (when looking at the 
back panel), and Source 1 is to its right. The back 
panel inputs for Source 1 and Source 2 are lo-
cated such that they are directly in line with 
their associated input controls on the front 
panel. This lets you locate input jacks more eas-
ily when viewing from the front of the unit. 
Though the XLR connectors support instru-
ment and microphone level inputs, when-
ever a TRS cable is plugged in to the 
Line(TRS) port, the XLR port on that chan-
nel is ignored.
