4. Hooking up Audio and
MIDI to the US-428
4.1 Hooking up audio
To monitor output from your computer,
connect the analog outputs of the US-
428 to your mixer, amplifier or powered
monitors. Output volume is controlled by
the LINE OUT level pot. If you’ve got a
digital mixer, external D/A converter, or
other device with S/PDIF input, you may
prefer to monitor via the US-428’s
S/PDIF output.
To record audio from the US-428 into
your computer, simply connect a device
to the appropriate input. Microphones
should be plugged into the INPUT A or
B XLR inputs.
Note that the US-428 does not supply
phantom power, so if you’re using
condenser mics, you’ll need an external
preamp or power supply. You can
connect line-level sources (e.g.,
keyboards and sound modules) into one
of the four LINE INPUTS (A through D).
If you wish to plug in a guitar, bass,
or other high-impedance source, simply
use input C or D, and move the sliding
switch next to the input connector to the
“Guitar” position. Finally, digital sources
(e.g., CD players, DAT’s etc) may be
connected to the S/PDIF INPUT.
The inputs of channels A and B are
available as either balanced XLR mic-
level inputs or balanced TRS (1/4”) line-
level inputs. While both sets of inputs
are capable of functioning
simultaneously, in actual practice this is
not recommended, as the signal level of
the inputs will be summed and very
likely interfere with each other.
Inputs C and D are switchable between
the unbalanced 1/4” analog inputs C
and D and the
S/PDIF digital input. The input source is
selected by pressing the INPUT C+D
switch.
Input level for analog sources is
regulated by the TRIM level pots
(diagram), located directly above the
