Stereo channels

2.2.1 Channel inputs
X2222USB X2442USB
Fig. 2.5: The various stereo channel inputs
Each stereo channel has two balanced line level inputs on jacks for left and
right channels. Channels 9/10 and 11/12 on the X2442USB feature an additional
XLR microphone jack with phantom power. If only the left jack (marked "L")
is used, the channel operates in mono. The stereo channels are designed to
handle typical line level signals, and, depending on model, have a level switch
(+4 dBu or -10 dBV) and/or a line GAIN control. Both jack inputs will also accept
unbalanced connectors.
LOW CUT and MIC GAIN
These two control elements operate on the XLR connectors of the X2442USB,
and are used to filter out frequencies below 75 Hz (LOW CUT) and to adjust
microphone levels (MIC GAIN).
LINE GAIN
Use this control to adjust the line signal levels on channels 13-16 (X2442USB only).
LEVEL
For level matching, the stereo inputs on the X1622USB, X1832USB and X2222USB
have a LEVEL switch to select between +4 dBu and -10 dBV. At -10 dBV
(homerecording level), the input is more sensitive than at +4 dBu (studio level).
2.2.2 Equalizer stereo channels
The stereo channels contain a stereo EQ section. The cut-off frequencies of
the high and low bands are 12 kHz and 80 Hz respectively, while the center
frequencies of the high-mid and low-mid bands are 3 kHz and 500 Hz
respectively. The HIGH and LOW controls have the same characteristics as the
EQ in the mono channels. Both mid range bands are of the peak filter type.
A stereo EQ is superior to two mono EQs on a stereo signal as two separate
EQs will usually result in a discrepancy between left and right channels.

2.2.3
In principle, the aux sends of the stereo channels function the same way as those
of the mono channels. As the aux sends are mono, the send from a stereo channel
is first summed to mono before it reaches the aux bus.
2.2.4
Fig. 2.6:
BAL
The BAL(ANCE) control has a similar function to the PAN control in the
mono channels.
The balance control determines the levels of the left and right input signals
relative to each other before both signals are routed to the left/right main mix
bus (or odd/even subgroup).
The remaining control elements in the stereo channels perform the same
functions as their counterparts in the mono channels (MUTE switch,
MUTE and CLIP LEDs, SOLO switch, SUB and MAIN switches and channel fader).

2.3
Where it was useful to trace the signal flow from top to bottom in order to gain
an understanding of the channel strips, we now look at the mixing console from
left to right. The signals are, so to speak, collected from the same point on each
of the channel strips and then routed to the main section all together.
2.3.1
Turning up the AUX 1 control in a channel routes the signal to the aux send bus 1.
◊
AUX SEND 1, 2 and 4
The AUX SEND 1 control governs the master send level of the mix created by
the individual channel AUX 1 sends.
Likewise, the AUX SEND 2 contol is the master control for the aux 2 bus,
and AUX SEND 4 controls the AUX 4 bus.

MON control, aux sends 1, 2 and 3 (FX)
As the X1832USB is equipped with an additional monitor path, its first
aux control in the channel strips is named MON. The console also has
a dedicated master fader (MON SEND) for this aux path.
