It is important to note that any changes made to the DSP Mixer will only affect what is audible from the mixer’s  
outputs—the DSP Mixer does not affect the signals that are sent to the audio application for recording   For example, 
if you are recording a vocalist and he/she tells you to turn up the vocal track so they can hear themselves better, you 
can increase the vocalist’s microphone channel in the DSP Mixer   This will make the vocal part louder in the vocalist’s 
headphones, but it will still be recorded into the audio application at the volume determined by the front panel Gain 
Adjustment Knob (4)  
The DSP Mixer is set up like a standard mixing console: There are 18 input channels, each with its own volume fader, pan 
and aux send knobs, solo ( 
 ), and mute (   ) buttons, as well as a master output section with its own pair of faders, 
and mute buttons   
A pair of channels can be linked together by clicking the link icon (   ) 
between the two channels   Linking channels allows you to adjust mute, solo, 
aux, and fader settings simultaneously by modifying parameters on either one 
of the linked channels 
The DSP mixer features multi-segment meters to show input channel levels 
(directly above each channel) and main mixer output levels (at the top right of the mixer)   The peak hold indication time as 
well as pre/post fader metering operation can be set from the Settings tab of the Control Panel   Finally, the clip indicators 
can be reset by clicking on the meter itself 
The signal source for each of the DSP Mixer’s 18 input channels can be selected from 52 possible signal streams  
(26 input streams and 26 software return streams)  Click the downward arrow (   ) and make a selection from the  
drop-down menu that appears   If an exclamation point ( 
 ) is displayed in place of a downward arrow, the currently 
selected stream is disabled because of S/MUX operation or by user preference  Grayed out and italicized drop-down 
selections are also disabled and will not stream audio 
if selected   To resolve this issue, select another input 
source that is not deactivated, reduce the sample rate 
of the interface, or increase the number of active input 
ports or software returns if possible (the reduction of 
input ports and software returns is covered in detail in 
the “Why are channels disabled?” text box on the next 
page 
As stated earlier, setting or adjusting the DSP Mixer 
will not affect the signal that is recorded into the audio 
application   For example, you’ll still be able to record 
a channel while its corresponding DSP Mixer channel 
is muted   You won’t hear the part through the DSP 
mixer as it is being recorded, but it will still record into 
your audio application and play back properly 
    
Useful Tips and Shortcuts:
• The input channel numbers (listed along the bottom 
of the mixer) can be renamed by clicking on them.  For 
example, if a bass guitar is routed to input channel 8, you 
can click the “8” at the bottom and rename the channel to 
“Bass.”  Note that changing a channel name only affects 
the labeling in the DSP Mixer and does not affect the 
way that input appears in your computer’s audio software.
• By alt-clicking (option-click for Mac users) the mute, 
solo, or link buttons, you can quickly mute, solo, or link 
all of the DSP Mixer’s 18 input channels at once.  This is 
also a handy feature in situations where you have muted/
soloed/linked multiple channels and need to quickly 
unmute/unsolo/unlink them.   Note that the mute buttons 
for the input channels (just above the faders) and the 
mute buttons for the aux sends (on the right side of the 
mixer) operate independently of each other.
• A fader or aux send knob can be set to unity gain by 
either double-clicking or alt-clicking it (option-click for 
Mac users).
NOTE:  Linking two channels will 
not have any effect on their pan 
or channel input selection.  These 
settings are always made on a 
per-channel basis.
