j
VoiceLift level adjustment encoder — This allows the user to adjust the level of the
VoiceLift (microphone) input level through 43 positions per rotation in 1 dB steps. The
VoiceLift Microphone Receiver input range is from ‑18 dB to +24 dB, default is ‑3 dB.
k
VoiceLift level adjustment LEDs — These three LEDs indicate the active audio level
(peak, normal and signal).
l
Page Sensor Sensitivity adjustment encoder — This allows the user to adjust the
paging sensor sensitivity level for the optional PPS 35 Priority Page Sensor or PPS
25, Priority Sensor Kit.
m
Page Sensor indication LED — This LED lights yellow during Paging System
broadcasts.
Front panel operation
NOTE: See the “
” on page 8 (figure 6) for the location of
input buttons, adjustment encoders, LEDs, and configuration port.
•
To change inputs, toggle the input button, 1 through 4 (video and audio), or 5
(line‑level stereo audio only).
•
To adjust audio input levels, rotate the Input adjustment encoder through 43 positions
in 1 dB steps (‑18 to +24 dB, default 0).
•
To adjust VoiceLift microphone levels, rotate the MIC adjustment encoder through
43 positions in 1dB steps (‑18 to +24 dB, default ‑3 dB).
NOTES:
•
Front panel LEDs indicate input and mic levels
(see image at right).
•
On initial switcher power‑up
the volume level is automatically adjusted to 80%
PEAK
NORMAL
SIGNAL
Signal threshold;
raise input gain.
Level has been
properly adjusted.
Level set too high,
lower input gain.
•
To adjust paging sensitivity, rotate the Paging encoder clockwise to increase and
counter‑clockwise to decrease sensitivity.
Configuration
The PVS 405D switcher can be controlled by a MediaLink Controller (MLC) or by an
RS‑232 device acting through the MLC. Alternatively, the switcher can be set up and
controlled via a host computer or other device (such as a control system) attached to the
front panel USB connector, or to the rear panel RS‑232 remote port of the switcher.
The control device (host) can use either the Extron Simple Instruction Set (SIS)
commands, the Global Configurator (GC) program for Windows, or the Product
Configuration Software (PCS), available at
.
Firmware updates can be made via the front panel USB port via Firmware Loader or PCS.
NOTE: See the
“SIS Communication and Control”
for a full list of the relevant SIS commands..
