INTRODUCTION
This manual covers installation and operation the RN-410 family of audio video switchers. Most of the operat-
ing principals are identical on all models. The unique characteristics such as connectors and pinouts are de-
tailed on the application drawings.
RN-410 FRONT PANEL OPERATION
SOURCE SELECTION
The source video and audio input are selected by pressing one of the 4 source buttons located on the left side
of the front panel. A single lamp will be illuminated to indicate the selection. Note that the audio source input
may be separately confi gured to a source different from that of the video input via the RS-232 interface.
This is referred to as audio breakaway.
The audio breakaway feature, when confi gured, will result in the lamp of the current video source input selected
being lit continuously and the audio breakaway source will blink intermittently at a rate of once per second.
Pressing a source select button will return both audio and video to the selected source and terminate the audio
breakaway feature.
AUDIO LEVEL ADJUSTMENT
The audio output level may be adjusted via the up and down buttons located on the right side of the front panel.
The audio range may be adjusted in 1 dB increments from a fl oor of –45 dB to +5 dB by either pressing and
holding the Vol Up or Down button or by discrete button presses. Each discrete press adjusts audio in 1dB
steps. When continuously pressing a volume up or down button, the audio output level will be ramped in 1
dB increments, traversing the entire range from –45 to +5 dB in approximately 6 seconds. The 5 audio output
lamps are illuminated accordingly to refl ect 6 ranges (including all OFF).
Audio mute may be toggled on and off by pressing the Audio Mute button to the immediate left of the audio
output level lamps. The user may adjust the audio output volume down while remaining in mute state.
However, if the user presses the volume up button while muted then the audio will be unmuted and the audio
output level will be adjusted accordingly.
AUDIO TRIM ADJUSTMENTS
The audio trim may also be adjusted for each of the 4 audio sources via the front panel. This is done by fi rst
pressing and holding the desired audio source input button (thus switching both video and audio to that source)
and then simultaneously pressing the volume up or down buttons to adjust the trim for the selected source. Note
that the lamps will not be illuminated to refl ect the adjusted trim and will remain illuminated to refl ect the audio
output level as may have been adjusted as above. The audio trim may be ramped up or down by holding both
the audio source button and the respective trim direction button and will traverse the –5 dB to +15 dB range in
approximately 2-3 seconds. Or the user can adjust in discrete 1 dB increments by discrete volume up or down
presses. When the audio source button is released, the audio trim adjustment is terminated.
AUDIO CARD ABSENT
The RN-410 is also available in confi gurations without an audio card. These RN-410 models have video
capabilities only. However, the RN-410 chassis still contains the Volume lamps and buttons as well as the
