does not affect the quarter-inch input of the
combo jack, which supports line level signals up to
+20 dBu.
Combo jack summary
Use these guidelines for 48V phantom power, pad
and gain settings on the two combo input jacks:
TRS quarter-inch line inputs/outputs
Quarter-inch line inputs and outputs are balanced
(TRS) connectors that can also accept an
unbalanced plug. The outputs are DC-coupled, so
they can be used for CV control output.
☛
Quarter-inch line outputs are not
cross-coupled. Therefore, when connecting them
to an unbalanced input, use a TRS plug with the
ring disconnected. Not floating the negative
terminal will short it to the sleeve ground and
cause distortion.
Various settings for the line inputs and outputs,
such as gain, trim, phase invert, etc. can be
accessed in the CueMix 5 app. See “Input tab” on
page 34 and “Output tab” on page 35.
Main outs
Like all I/O on the UltraLite-mk5, the main
outputs operate as an independent pair (they don’t
share signal with any other output pair). In a
standard studio configuration, the main outs are
intended for a pair of primary studio monitors,
but they can be used as regular outputs for any
purpose. With adjustable Precision Digital Trim™,
they support a wide range of industry-standard
reference levels. Main out volume is controlled by
the MAIN VOL knob on the front panel: turn it to
view volume knob overlay in the display, then
push the knob until you see
Main Trim
and turn it
to adjust the master volume output.
Analog I/O calibration
All analog inputs and outputs can be calibrated to
support a variety of standards, including
EBU-R68, SMPTE RP-155, +4dBu, -10dBv,
2vRMS and 1vRMS.
The line inputs are equipped with +1 to +20 dB of
digital gain, adjustable in 1 dB steps.
The line outputs, main outs and headphone outs
are equipped with a range of digital trim from 0 to
-100 dB, adjustable in 1 dB steps.
Trim and gain controls can be accessed in the
CueMix 5 app. See “Input tab” on page 34 and
Pre/Post Fx switch for line inputs
Each analog input provides EQ and compression.
The mic/line/inst inputs include gating. These
effects can be applied to the input as needed (items
