PFL (LEVEL SET)
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
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 the 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 QX2442USB all aux returns, and on the QX1832USB
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 (LEVEL SET)
The PFL (LEVEL SET) LED indicates that the peak meter is set to PFL mode.

PHONES jack
You can connect headphones to this ¼" stereo jack (QX2442USB: 2 phones jacks).
The signal routed to the PHONES connection is the same as that routed to the
control room output.
2.3.12 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.
