MIXER EFFECTS
The EQ, compressor, gate and reverb processor in
the UltraLite-mk5 are available when operating
the unit at 1x and 2x samples rates. At 4x sample
rates (176.4 or 192 kHz), the following effects are
disabled:
■
All input effects
■
Reverb
However, all mix bus EQ’s (including Phones)
remain enabled during 4x operation.
DSP-driven mixing and effects
The UltraLite-mk5 effects are driven by a
powerful DSP that delivers 32-bit precision and
plenty of bandwidth for no-latency processing.
Effects can be applied when operating as an audio
interface or as a stand-alone mixer without a
computer.
Advantages over host-based mixing and
processing
The hardware mixer in the UltraLite-mk5
provides several advantages over mixing and
processing in your host audio software:
■
No buffer latency. The DSP-mixer provides the
same near-zero latency throughput performance
as a conventional digital mixer. Effects processing
doesn’t impact your computer’s CPU.
■
DSP mixing and routing can be maintained
independently of individual software applications
or projects.
■
DSP-driven mixing can function without the
computer, allowing the UltraLite-mk5 to operate
as a portable, stand-alone mixer with effects.
Accessing mixer effects
To access the EQ, compressor or gate for a
channel, click its thumbnail at the top of the
channel strip (item #1, 2 or 3 on page 38).
FOUR-BAND PARAMETRIC EQ
Analog input channels (items 1 and 2 on page 37)
provide four bands of center-frequency
parametric EQ filtering as shown on page 39. The
High and Low bands include shelf filtering
options. Master faders provide three bands of
parametric EQ.
Enabling EQ bands
Each band has an enable/disable button (item #6
on page 39), allowing you to enable as few or as
many bands as needed.
EQ filter controls
The EQ filters have three controls (item #8 on
page 39):
Click a value to edit it numerically. Or drag its
corresponding control handle in the graph above.
Controls for each EQ band are color-coded.
EQ filter characteristics
EQ is one of the most widely used processing tools
and can be applied to many different situations,
from minor corrective tasks to creative tone
sculpting. The four-band EQ has been designed to
be flexible enough to cover a broad range of
applications. By adjusting Gain and Bandwidth
together, you can emulate the smooth and musical
character of classic analog EQ circuits.
Filter types
The Low and High bands offer a shelf option that
is similar to those found in most conventional
parametric EQs. The Low band also provides an
additional low-cut filter option to filter out low
frequencies below the frequency setting.
Control unit range
Frequency Hertz 20 to 20,000
Gain dB -20.00 to +20.00
Bandwidth Octaves 0.01 to 3.00
