Chapter 2 Installation Section 8
The XL mic input and XL pre output are the primary connections
to the MP 5.0. The XL microphone input (1) is designed to receive
a signal from any low impedance balanced microphone. The
preamp output (2) is a line level output and is switchable from
"Transformer-Balanced" or "Active-Balanced" output.
The Insert Send (3) and Insert Return (4) jacks provides line
level interstage access to connect a limiter or equalizer. Any
device interfaced to these jacks will be processed after the main
preamp gain stage and before the high pass filter section. The
processed signal is available at the main XL output, the left and
right mix outputs and the left/right output terminals on the mix link
connector.
The active-balanced TRS insert jacks serve a secondary function
on the MP 5.0. The Insert Send may be used as an additional
balanced Pre Out-B (3) and the Insert Return may be used as an
auxiliary Line In (4).
The active-balanced TRS left and right Mix Outputs (5) provide a
low impedance source for connection to the input of any balanced
line input.
The output circuits of the MP 5.0 were designed for balanced lines
and should only be connected to balanced inputs. If that is not
possible and it is necessary to connect to an unbalanced input, care
must be taken not to connect the low (-) terminal to ground.
If the low (-) terminal of these outputs are connected to ground, the
result will be a high level of audio distortion.
