EXT 1 INPUT
These stereo unbalanced RCA phonos provides an external input that would typically be
used to monitor the on-air or post-processor output to ensure it is correct.
LED Meter Display
The LED Meters give a visual representation of the audio routed to the presenter
headphones including CUE/PFL and SPLIT CUE/PFL signals. They can be configured to
display either PPM or VU. The PPM meters have a 1-7 scale and are configured such that a 1
kHz signal, at 0dBu at the PGM output, will indicate a meter reading of 4. Each mark on the
PPM scale indicates a 4 dB change in signal level. The VU meter operates between -20 and
+3 volume units and follows the standard definition for a VU meter. A red LED indicates
which scale is currently selected. To change scale, ensure all faders are closed, press and hold
the PGM button and then press the EXT 1 button.

PGM, REC & EXT 1 Buttons
These buttons select the source for the monitoring section of the S0. The selected source
will be routed to the monitor output and the presenter and guest headphones. These
buttons do not affect the signals on the Main Program and Record outputs. The PGM button
illuminates green, the REC button illuminates red and the EXT 1 button illuminates amber
when selected. One button is selected at all times.
