12 Balanced input + loop thru XLR's
These XLR-3 female and male connector are
paralleled and are the input & loop thru for a
balanced signal (mic. or line level).
13 Mono left / stereo input jack
This 1/4" jack connector is the input of the left
signal of a stereo signal when a mono jack is used
(input 14 is the right input), or the left and right
signals when a stereo jack is used (input 14 is not
used). It accepts signals of line or speaker level.
14 Mono right / mono input jack
When no signal is connected to the left jack input
(13), the mono signal on this input is sent to the left
and right cans of the headphone. When there is
also a mono signal connected to the left jack input
(13) the signal on this input is sent only to the right
input (input 13 is the left input). It accepts signals of
line or speaker level.
15 Stereo loop thru connector
This jack connector is always configured as a
stereo loop thru for the signals connected to the
unbalanced inputs 13 and/or 14.
When a stereo signal is connected to input 13 this
connector provides a stereo link. When mono left
and mono right signals are connected to inputs 13
and 14, this connector outputs those signals as a
stereo signal (left=tip, right=ring). When a mono
signal is connected to input 14, this connector
outputs the mono signal (on tip and ring). This
connector is especially useful for connecting
multiple headphone amplifiers to one source.
