Tb Level; Stereo Returns; 2Tk Level; 2Tk Replaces Mix Output - SoundCraft LX7-2 Technical Manual

8 - TB LEVEL

A balanced input is provided for a Talkback microphone. The signal may be routed
selectively to Aux 1/2 or 3/4 (which might typically be used for performers’ foldback) or
Mix L/R by pressing the appropriate switches. The signal level is adjusted by the TB LEVEL
control.

9 - STEREO RETURNS

Two balanced Stereo Returns are available for the outputs of effects units and are mixed
directly to the Mix L/R busses at a level set by the RET-1 or RET-2 controls. If a mono
source is used, plugging into the Left jack only automatically feeds to the signal to both
Left and Right.

10 - 2TK LEVEL

The rotary control sets the level of the 2 Track Tape input, which is routed to the headphones,
monitor outputs and meters, or directly to the Mix outputs by pressing the adjacent switch
(12). These unbalanced inputs, on RCA phono connectors, are ideal to connect the
playback of a tape machine for monitoring.

11 - 2TK REPLACES MIX OUTPUT!

This switch does what it says! When pressed the Mix output is switched to the 2 Track
input and is an ideal way of feeding pre-show music to the main outputs in live applications
without using up valuable input channels. For example, with the switch pressed and a CD
connected and playing pre-show music, the engineer can be setting up channel levels,
adjusting EQ, talking back to performers and monitoring any part of the mix (including
final Mix) without affecting the sound to the audience. Releasing the switch instantly
swaps the Mix Outputs back to the mixer and cuts off the CD.
CAUTION: Pressing this switch cuts off the
normal Mix L/R signal and it should therefore NOT
be used during live performance or recording
12 - MONITOR SOURCE SELECT
These switches allow a choice of 2TK, C (mono), Mix or Groups as the source for the
Phones, Monitor outputs and meters, and may be selected individually or as a combination.
NOTE: If NO switches are pressed, there will be NO signal on the meters or monitors!
13 - MONITOR + PHONES
This control sets the output level to the MONITOR LEFT & RIGHT outputs. If Headphones
are plugged into the PHONES jack the Monitor outputs are cut off, and the knob then sets
the headphone listening level. When the PHONES are unplugged the Monitor output is
restored. The source for the Monitor and Phones is selected by the five switches (13)
above the control.
When any PFL or AFL switch is pressed the source for the Monitor outputs and Headphones
is switched to the mono PFL/AFL signal without interrupting the other outputs from the
mixer, to allow individual signals to be monitored. The original monitor source is restored
when the PFL/AFL switches are released.
14 - PFL/AFL
The PFL/AFL LED illuminates to show that a PFL/AFL is active and is the source for the
monitors and meters. The LED will normally be OFF
