FLIP – This reverses the mic/line selection on individual channels.
ø
(Phase) – This reverses the phase of the selected channel input.
48V – When selected provides phantom power to the associated microphone.
HIGH-Z – Increase the input impedance of the microphone input from 1.2K! to 8K!.
This allows the connection of line level outputs to the mic input if required, and
provides an alternative input impedance for some dynamic microphones.
MIC or LINE inputs are automatically selected by the STATUS switches on the SL952
Master Facilities Module. In RECORD or REPLAY status, all inputs switch to MIC. In
MIX, all inputs switch to LINE. The FLIP button reverses the input selection on
individual channels. The MASTER INPUT FLIP button on the SL952 panel reverses
the input selection on all channels.

Channel Input Section

The channel input can receive any one of three inputs:
LINE – Selects a Line level input from patch row D via the
LINE trim pot (+20dB to -20dB). The pot is indented at unity
gain. A green LED indicates Line Input selection.
MIC – selects a Microphone input from Patch row B via the
MIC trim control.. This is continuously variable from +15db to
+75dB of gain, with a 20dB pad switch shifting the gain range
to -5dB to +55dB. A red LED indicates Mic Input selection.
SUB GP – When this button is pressed, the above selections are
overridden and the input of the channel is taken from that
module's multitrack bus mix amp. This allows modules 1-48 to
be used to as audio subgroups.
