External Meter socket
This can be used to feed the main Program PGM L & R signals to external metering equipment. These are line level
analogue signals, the level at 0VU will be 0dBu.
+/- 15V power is also available to power meter circuits, current draw should be kept under 100mA or so.

Configuration Switches
The tiny slide switches accessible on the rear panel are for configuring the XB-14’s channel ON switches. In the up position,
the channel ON switch will act as a normal ON/OFF switch affecting the channel signal accordingly. If the slide switch is moved
down to the “ON” position, then the corresponding channel’s ON switch will be disabled (made so that it is jammed ON).
The green LEDs in the switch will then permanently illuminate. UNLESS….
Unless you are using the Stereo channel ON switches for transport Start/Cue and would like the channel mute circuit disabled
but the switch illumination still to follow the switch position. In this case use the last switch in the row to disable the mute
circuit on all 4 stereo channels, but make the illumination follow the switch position.
If you want, you can disable the Stereo channel mute circuit on an individual channel basis using the Stereo Inputs 1,2,3 & 4
slide switches individually. This will make the channel permanently on and the switch illumination also permanently on.
This may seem like a fussy complication, but could be useful if you want to revert to basic operation, where only the faders
control the signal going out on air, disabling the ON switches so the operator cannot turn off the channel accidentally, but still
want the switch illumination on certain stereo channels to follow the Start/Cue on the CD player or deck.
