ABOUT THE ULTRALITE-MK3 HYBRID
12
The LCD also provides activity metering for all 
UltraLite-mk3 inputs and outputs.
16-BIT AND 24-BIT RECORDING
The UltraLite-mk3 system handles all data with a 
24-bit signal path, regardless of the I/O format. You 
can record and play back 16-bit or 24-bit audio files 
at any supported sample rate via any of the 
UltraLite-mk3’s analog or digital inputs and 
outputs. 24-bit audio files can be recorded with any 
compatible host application that supports 24-bit 
recording.
CUEMIX FX 32-BIT FLOATING POINT 
MIXING AND EFFECTS
All UltraLite-mk3 inputs and outputs can be 
routed to the on-board CueMix FX 16-bus (8 
stereo) digital mixer driven by hardware-based 
DSP with 32-bit floating point precision. The 
mixer allows you to apply no-latency effects 
processing to inputs, outputs or busses directly in 
the UltraLite-mk3 hardware, independent of the 
computer. Effects can even be applied when the 
UltraLite-mk3 is operating stand-alone (without a 
computer) as a complete portable mixer. Input 
signals to the computer can be recorded wet, dry, 
or dry with a wet monitor mix (for musicians 
during recording, for example).
Effects include reverb, parametric EQ and 
compression/limiting. The UltraLite-mk3’s Classic 
Reverb™ provides five different room types, three 
frequency bands with adjustable crossover points, 
shelf filtering and reverb lengths up to 60-seconds. 
Two forms of compression are supplied: a standard 
compressor with conventional threshold/ratio/
attack/release/gain controls and the Leveler™, an 
accurate model of the legendary LA-2A optical 
compressor, which provides vintage, musical 
automatic gain control.
CueMix FX also provides 7-band parametric EQ 
modeled after British analog console EQs, 
featuring 4 filter styles (gain/Q profiles) to 
effectively cover a wide range of audio material. 
Low-pass and high-pass filters are also supplied 
with slopes that range from 6 to 36 dB. The EQ 
employs extremely high precision 64-bit floating 
point processing.
The UltraLite-mk3’s flexible effects architecture 
allows you to apply EQ and compression on every 
input and output (a total of 24 channels), with 
enough DSP resources for at least one band of 
parametric EQ and compression on every channel 
at 48 kHz. However, DSP resources are allocated 
dynamically and a DSP meter in the CueMix FX 
software (included) allows you to keep tabs on the 
UltraLite-mk3’s processing resources. Each input, 
output and mix bus provides a send to the Classic 
Reverb processor, which then feeds reverb returns 
to mix busses and outputs, with a selectable split 
point between them to prevent send/return 
feedback loops.
HOST AUDIO SOFTWARE
The UltraLite-mk3 system ships with standard 
Windows drivers that allow you to record, edit, 
play back and mix your UltraLite-mk3 projects 
using your favorite Windows audio software.
