LEVEL SETTING:
When recording to digital recorders, the recorder’s meter should
not go into overload. This is because, unlike analog recordings,
it takes only slightly excessive levels to create unpleasant digital
distortion.
When recording to analog, the VU meters of the recording
machine should reach approx. +3 dB with low-frequency signals
(e.g. kick drum). Due to their inertia, VU meters tend to display
too low a signal level at frequencies above 1 kHz. You should
only drive instruments such as a Hi-Hat as far as -10 dB.
Snare drums should be driven to approx. 0 dB.
+
The peak meters of your EURORACK display level
almost independent of frequency. A recording level
of 0 dB is recommended for all types of signal.
MODE
The MODE switch determines whether the channels’ SOLO
switch operates as PFL (Pre Fader Listen) or as solo (Solo In
Place).
LEVEL SET (PFL)
To activate the PFL function, press the MODE switch. The PFL
function should, as a rule, be used for level setting (TRIM). The
signal is sourced pre-fader and assigned to the mono PFL bus. In
“PFL” mode, only the left side of the peak meter is in operation. A
PFL’d channel should be driven to the 0 dB mark of the VU meter.
NORMAL (SOLO)
When the MODE switch is not depressed, the stereo solo bus
is active. Solo is actually short for “Solo In Place”. This is the
customary method for listening to an individual signal or to a
group of signals. As soon as a solo switch is pressed, all channels
not solo selected are muted in th e monitor path (control room
and phones). A channel’s position in the stereo image is
maintained. The solo bus carries the output signals of the channel
pan controls, the aux sends and the stereo line inputs. On the
UB2442FX-PRO all aux returns, and on the UB1832FX-PRO only
aux return 2 can be routed to the solo bus. The solo bus is, as a
rule, taken post-fader.
+
The PAN control in the channel strip offers a
constant power characteristic. This means that the
signal is always at a constant level, irrespective of
position in the stereo panorama. If the PAN control
is moved fully left or right, the level in that channel
increases by 4 dB. This ensures that, when set at
the center of the stereo image, the audio signal
does not appear louder. For this reason, with the
solo function activated (Solo in Place), audio signals
from channels with PAN controls that have not been
moved fully left or right are displayed at a lower
volume than in the PFL function.
As a rule, solo signals are monitored via the control room
outputs and headphones jack and are displayed by the level
meters. If a solo switch is pressed, the signals from the tape
input, the subgroups and the main mix are cut from these outputs
and the level meter.
MAIN SOLO
The MAIN SOLO LED lights up as soon as a channel or aux
send solo switch is pressed. The MODE switch must be set to
“Solo”.
PFL
The PFL LED indicates that the peak meter is set to PFL mode.

PHONES jack
You can connect headphones to this 1/4" stereo jack
(UB2442FX-PRO: 2 phones jacks). The signal routed to the
PHONES connection is the same as that routed to the control
room output.
2.3.11 Subgroups and main mix fader
You use the high-precision quality faders to control the output
level of the subgroups and the main mix.
LEFT/RIGHT switch
The switches located above the subgroup faders assign the
subgroup signal either to the left or right side of the main bus.
Similarly, it can be routed to both sides or none at all. In the latter
case, the submix is present only at the corresponding subgroup
outputs.

The graphic stereo equalizer allows you to tailor the sound to
the room acoustics.
EQUALIZER
Use this switch to activate the graphic equalizer.
MAIN MIX/MONITOR
This toggles the graphic equalizer between the main mix and the
monitor mix. With the switch up (not depressed), the equalizer is
active in stereo on the main mix, and inactive on the monitor mix.
When the switch is depressed the equalizer is active in mono
on the monitor mix, and inactive on the main mix.
FBQ FEEDBACK DETECTION
The switch turns on the FBQ Feedback Detection
System. It uses the LEDs in the frequency band
faders to indicate the critical frequencies. On a
per-need basis, lower the frequency range in
