Quick Reference: UltraLite-mk3 Hybrid Front Panel
1. This XLR/TRS combo jack accepts either a mic cable or a 
cable with a quarter-inch plug. It is equipped with 
approximately +60 dB of boost for the mic (XLR) input 
and +32 dB of boost for the instrument (TRS) input. 
Separate settings are maintained for the XLR and TRS 
inputs for saving with presets. The XLR (mic) input can 
also be supplied with 20 dB pad and 48V phantom 
power.
2. These two Precision Digital Trim™ rotary encoders 
provide +60 dB and +32 dB of boost, respectively, for 
the mic (XLR) and instrument (TRS) inputs on the front 
and rear panel. Adjustment can be made in approxi-
mately 1 dB increments. Both have preamps, so you can 
plug in just about anything: a microphone, a guitar or 
even a synth. For +4 dB signals, use the rear panel TRS 
inputs. Use the trim knob and input level meter in the 
LCD to calibrate the input signal level. For the Mic (XLR) 
input, Push the TRIM encoder to toggle a 20 dB pad; push 
and hold to toggle 48V phantom power.
3. Turn the VOL knob to control the headphone volume. The 
LCD provides visual feedback for the headphone volume 
setting as you turn the knob. Push the knob once to view 
the current volume setting in the LCD display; push it 
again to control the UltraLite-mk3’s MASTER VOLUME 
setting. From the factory, MASTER VOLUME controls the 
(TRS) MAIN OUTS 1-2 on the rear panel, but MASTER 
VOLUME can be programmed to control any combination 
of outputs. See “The Monitor Group” on page 84 for 
details.
4. When power is off, push the VOL knob to power on the 
UltraLite-mk3; press and hold to turn it off. When 
connected to the computer via FireWire, the 
UltraLite-mk3 is powered by its FireWire connection to 
the computer. When connected via USB, it must be 
powered with the included DC power adapter.
5. The multi-purpose backlit LCD provides metering for all 
of the UltraLite-mk3’s inputs and outputs. It also gives 
you access to the UltraLite-mk3’s built-in mixer and 
other settings. There are eight independent stereo mix 
busses. Each mixes all inputs (or any subset you wish) to 
a stereo output of your choice. The four knobs to the right 
of the LCD correspond directly to the four labeled 
sections of the LCD. Push the PARAMETER knob repeat-
edly to cycle through the three main LCD display modes: 
METER, CUEMIX and SETUP. 
METER mode provides level meters for each input and 
output. The labels above and below the LCD refer to all of 
the UltraLite-mk3’s inputs and outputs (both analog and 
digital). 
CUEMIX mode lets you program the UltraLite-mk3’s on-
board CueMix FX mixer. Use the CHANNEL knob to 
choose the input, output or mix you wish to edit. Push it 
to switch among inputs, outputs and busses, then turn it 
to choose the desired channel or bus. Use the PAGE, 
PARAM and VALUE knobs to access the settings for the 
chosen channel. 
SETUP mode lets you access general settings. Use the 
PARAMETER knob to browse settings, and use the VALUE 
knob to adjust them.
6. This is a standard quarter-inch stereo headphone jack. 
From the factory, its output matches the main outs on 
the rear panel. But it can be programmed to mirror any 
other output pair (digital or analog). It can even be 
programmed to serve as its own independent output. 
Use the volume knob above to control its level.
7. Push the TRIM rotary encoder to toggle the 20 dB pad 
independently for each mic input. Hold it in momen-
tarily to toggle 48V phantom power independently for 
each mic input.
