(EN) Step 2: Controls
(1) SOURCE 1 and SOURCE 2/USB
buttons control which input
sources are active. When a source
is active, the LED ring around the
button lights up.
(2) MONO button collapses the left-
right stereo image down to mono.
(3) DIM button reduces the listening
volume by about 15 dB. Use
this function to switch quickly
between loud and quiet volume
levels when mixing. You can also
use this function when plugging
in, removing or switching between
headphones to protect your
hearing from loud clicks, pops
or damaging volume dierences
between two sets of headphones
with diering impedance values.
(4) VOLUME control adjusts the
overall volume level for all
speaker outputs.
WARNING! Make sure all volume
and level controls are turned fully
counterclockwise before powering
on the unit.
WARNING! Excessive, sustained
volume levels can cause
hearing damage.
(5) CROSSFEED control blends the left
and right headphone channels to
simulate the characteristic stereo
panorama produced by monitor
speakers in an open acoustic space.
In an open room, the sound from
each monitor speaker enters both
ears and gives the brain additional
timing information about the
sound, which then aects the
listener’s perception of the stereo
eld. In contrast, headphones
feed each ear a starkly separated
stereo channel, with no crossover
to the opposite ear. This lack of
crossover can cause mixes to sound
very dierent on headphones,
as well as being a more fatiguing
listening experience. By using
the CROSSFEED function, you can
more closely simulate the stereo
sound of monitors while mixing on
headphones, which means
your headphone mixes will
more closely match the mixes
you produce on monitors, and
you will experience less ear
fatigue from long sessions
wearing headphones.
(6) PHONES knobs control the
volume level for each of the two
headphone outputs.
(7) MONITOR buttons activate and
deactivate the A, B and C speaker
groups connected to the related
MONITOR OUT XLR jacks. By using
these buttons, you can compare
mixes on dierent sets of stereo
speakers (groups A and B), or you
can activate a single fullrange
speaker for an additional option
to monitor in mono (group C,
which has only a single output).
The group C output can also
be used to connect a separate
subwoofer to check the extreme
low frequencies in your mix. When
a particular MONITOR group is
active, the LED ring around the
related button will light up.
(8) CROSSFEED ON button activates
the CROSSFEED function. When
CROSSFEED is active the LED ring
around the button will light up.
(9) PHONES 1 and PHONES 2 outputs
accept headphone connections
over ¼" TRS stereo connectors.
Each output has a dedicated
knob for individual volume
control. Whenever you change
headphones, press the DIM button
to protect your hearing from
clicks, pops or unexpected volume
dierences between headphones
with diering impedance ratings.
(10) POWER LED lights up when the
unit is powered on.
(11) USB type B connection allows
you to stream audio into the
MONITOR2USB directly from
your computer. The USB
connection is activated by the
SOURCE 2/USB button. When
the USB connection is in use,
the INPUT 2 analog connections
will still be active, and the audio
from both connections will be
summed together. In this summed
USB/INPUT 2 signal, the relative
signal levels will need to be
matched by using the level
controls on the source equipment.
NOTE! The USB audio interface
is class-compliant, so no special
software drivers are required,
and low latency ASIO* drivers can
also be used (such as ASIO4ALL).
However, depending on host
software used, the default USB
input may be set in software as a
mono microphone with excessive
software gain available, the
user may need to recongure
USB input as a stereo source
and reduce software gain to an
appropriate level.
*ASIO is a trademark and
software of Steinberg Media
Technologies GmbH.
(12) +4 dBu / -10 dBV button allows
you to change the level sensitivity
of the INPUT 2 group of XLR jacks.
The +4 dBu setting matches
the line-level standard for pro
audio gear, while the -10 dBV
setting matches the sensitivity
standard for consumer audio
(e.g., CD/DVD players). By properly
matching the input sensitivity,
you can more easily match levels
between the two groups of stereo
inputs, and therefore avoid large
volume dierences at
the outputs.
(13) INPUT 2 accepts balanced
audio signals from devices using
XLR cables. To activate INPUT 2,
press the SOURCE 2/USB button
on the front panel. The sensitivity
for these inputs can be changed to
match pro audio gear
(+4 dBu) or consumer electronics
(-10 dBV) by using the +4 dBu
/ -10 dBV button. The INPUT 2
analog connections remain active
when the USB audio connection
is being used, and the audio from
both connections will be summed
together. In this summed USB/
INPUT 2 signal, the relative signal
levels will need to be matched
by using the level controls on the
source equipment.
