While phantom power is switched on, do not connect or
disconnect microphones on the mixer (or the stagebox/wallbox).
Connect any micro-phones before switching on phantom power.
Additionally, monitor/PA speakers should be muted before you activate
the phantom power supply. After switching on, wait approx. one
minute before adjusting the input gain so that the system has time
to stabilize.

LEVEL SETTING:
When recording to digital recorders, the recorder’s meter should not go into
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
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.

MODE

The MODE switch determines whether the channels’ SOLO switch operates as PFL
(Pre Fader Listen) or as solo (Solo In Place).
PFL (LEVEL SET)
To activate the PFL function, press the MODE switch. The PFL function should, as a
To activate the PFL function, press the MODE switch. The PFL function should, as a
rule, be used for level setting (GAIN). 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.
SOLO (NORMAL)
When the MODE switch is not depressed, the stereo solo bus is active. Solo is
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.

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.
