 f IN GAIN
Sets and displays the MIC / LINE input level. 
Both inputs share the same gain settings and are 
not meant to be used simultaneously; switching 
from a Mic to a Line level signal will likely require 
resetting IN GAIN. To set input level automatically, 
use the AUTO MIC-GAIN function by holding 
the Input Gain button and following the prompts. 
When any digital input is selected (USB or SPDIF) 
the IN GAIN does not control the digital input 
level. Use your transmitting device to adjust level.
 f PHANTOM
Turns 48V phantom power on and off for use 
with condenser microphones. 
 f AUX LEVEL
Set the input level of for the Aux input.
 f OUTPUT
The congures the outputs to be STEREO (de-
fault), MONO or DUAL MONO. The STEREO 
option outputs discrete Left and Right audio 
material when connected to a stereo monitor or 
PA system. 
In MONO mode, the Left output is the summed 
mono mix of VoiceLive Rack including effects. The 
Right output is dry with only Tone applied to the 
MIC or LINE input signal. This is useful when a live 
sound engineer wants to control the balance of 
wet/dry mix at the mix position. In this case, set 
LEAD MUTE to ON.
In DUAL MONO mode, the effected vocal 
comes from the left output and effected guitar is 
produced from the right output. This allows you 
to have a sound tech control the level balance 
between wet vocal (vocal with harmonies and 
effects) and wet guitar. 
 f DIGITAL IN
Selects between SPDIF and USB physical inputs 
as the input and also species where the incom-
ing digital signal is routed. By default the routing 
is USB: STEREO, where the digital input is routed 
to the same path as the AUX input, but is not 
passed on to the digital output. 
When set to USB: VOX L / INST R, or S/PDIF: 
VOX L / INST R the digital input replaces the 
analog MIC/LINE and GUITAR inputs and the 
MIC and GUITAR IN connections are disabled.
Sample rate is synchronized automatically to the 
incoming digital audio stream. There is no sample 
rate adjustment in VoiceLive Rack. When process-
ing an analog input such as the MIC and sending 
to VoiceLive Rack’s digital out, sending a short bit 
of audio from your recording application to either 
Digital input will set the sample rate. 
When DIGITAL IN is set to USB (or SPDIF): 
STEREO, harmonies will follow the stereo audio 
coming from the selected digital input on presets 
where NATURALPLAY is set to AUX INPUT.
While the VoiceLive Rack is connected via USB 
to your computer, other applications such as your 
browser may not make sound through your regu-
lar sound card. In this case, disconnect VoiceLive 
Rack’s USB cable.
 f DIGITAL OUT
Congures the digital output between the stereo 
mix of VoiceLive Rack (FULL MIX), and separated, 
dry outputs used for recording (VOCAL & GUI-
TAR). 
 f LEAD MUTE
Turns the lead voice off in all presets. This is useful 
in the live sound engineer setting described above
