Front Panel
The user interface for AirCleaner consists of an illuminated front-panel LCD menu
display with two rotary knobs, providing simple and fast system setup. Each of the
two rotary knobs features an integrated push button for selecting menu items and
confirming parameter changes. The only other control mechanism on the front panel
is the
BYPASS
button.
Figure 4-15. AirCleaner Front Panel User Interface
BYPASS Button
This button is used in case AirCleaner needs to be eliminated from the audio/video
signal pathway for trouble-shooting purposes; or in case AirCleaner becomes faulty
while on the air.
When pressed and illuminated, the
BYPASS
button activates the internal bypass
relays. To activate the push-button, swing open (from bottom) the clear plastic cover
that protects the switch; then push the button.
Figure 4-16. Bypass Button on AirCleaner Front Panel
All audio/video inputs and outputs are equipped with bypass relays that are also
automatically activated in the event of complete power supply failure (in the case of
AirCleaner systems fitted with redundant power supplies, this would mean both
power supplies have failed). When the bypass relays are active, the
PGM IN
audio/
video is routed directly to
PGM OUT
with no delay in the pathway. The menu
parameters will not be active at this time and the
STEREO ANALOG AUDIO OUTPUT
jack will not be active.
NOTE
Disabling BYPASS will return AirCleaner to “Normal” operations,
and results in a rewrite of the audio/video delay buffers inside
AirCleaner, to activate the delays as defined by the delay
parameters. During this period, a very brief “glitch” will occur on
the audio/video outputs; the video freezes and audio mutes.
