Main & Subs Mix, USB Out, 2-Track Return, and more!
54. USB Out Switch 
    [ProFX16v2, ProFX22v2, ProFX30v2]
This switch allows flexibility on the recordable 
signals. The default switch configuration (disengaged) 
allows the main L/R mix to be recorded for convenient 
stereo mixes of the show. Engaging the switch routes 
subgroups 1-2 over the USB connection to your favorite 
DAW software for an alternate 2-track recording.
55. 2-Track Return Tape / USB Switch 
    [ProFX16v2, ProFX22v2, ProFX30v2]
This determines if the 2-track return gets its  
signal from the RCA “tape” inputs (switch disengaged) 
or USB (switch engaged).
56. 2-Track Return Level 
    [ProFX16v2, ProFX22v2, ProFX30v2]
This knob controls the overall level to the mains of 
the tape (RCA) or USB, depending on the position of 
the 2-track return tape/USB switch. This knob's level 
ranges from off, through unity (center detent position), 
on up to 15 dB of extra gain (fully clockwise).
57. Tape Level 
  
[ProFX8v2, 
ProFX12v2]
This knob controls the input level of signals  
entering the tape inputs. It is conveniently located  
close to the break switch so all channels may be  
quickly muted while bringing up the background  
music while the band is taking a break.
58. Break Switch and LED
This important “take-a-break” switch quickly mutes 
all the microphones and line-level inputs to the main 
outs, cr outs and phones when the band is between sets. 
This will prevent protestors or rogue karaoke singers 
from storming the stage at the interval. 
The monitor send and FX send are not affected.  
If there is no sound coming out of the system, be sure  
to check this switch first.
It is possible to play the stereo RCA tape inputs in  
the main stereo mix or play audio coming in from the 
computer via the USB inputs. For example, a soothing 
CD may be played while the band is off stage.
The adjacent break LED [ProFX16v2, 
ProFX22v2 and ProFX30v2] will illuminate  
as a reminder that the channels are muted.
52. USB Input Level 
 [ProFX8v2, ProFX12v2]
This control adjusts the signal level of the two  
channels coming in from the computer, via the  
USB port, relative to the mix of the other channels. 
Adjust it carefully to achieve the desired mix with  
the other channels.
The USB input from audio software could  
be individual instrument tracks, a mix of tracks,  
or processed tracks.
53. USB Thru 
 [ProFX8v2, ProFX12v2]
In addition to a mix of the other channels, the USB 
output to the computer may contain any input from 
the computer if this switch is down. (This switch only 
affects the output to the computer, not the headphones 
or main mix.)
• 
If disengaged (out), the USB output to the 
computer will just be the main mix. This is a 
good position for overdubbing, as any playback 
from the computer may be played through the 
main speakers and headphones, while playing 
along with a guitar and recording only the   
guitar via USB. This is also good for live    
recording as a safeguard against feedback. 
Here, the USB level knob should also be down. 
• 
If pressed in, the USB output to the computer 
will be the main mix, including any audio 
coming in from the computer. This is a good 
position to record live performances where 
playback of audio from the computer is also 
part of the performance.
