There are two menu items used to set the volume of the analog audio
outputs. When either the Left level or Right level menu items are selected,
the right LCD panel will display an audio level adjustment screen. The active
adjustment will be highlighted while the other adjustment will be shown in
dark text. Rotate the control knob or press the and buttons to change
the current audio level. Turning the control knob while pressing it in allows
making quicker adjustments in larger steps.
The audio level range is from +10.0 dBu down to –30.0 dBu. The lowest
setting is Mute
, which effectively disables the analog audio channel. The
adjustments are done in steps of 0.1 dBu (decibels unloaded).
Caution: These
menu items are live controls. Any changes to the audio
levels will immediately affect the analog audio outputs.
Left 10.0dBu
Right 0.0dBu
4.4.6.3. Setting the Analog Audio Generation Mode
There are two output modes for the Analog Audio outputs.
Select Steady tones to generate continuous audio tones as defined by the
Left Frequency and Right Frequency controls. These tones will be very pure
with a low total harmonic distortion.
Select Timed toned for event driven tone generation. There are a total of ten
audio events that can be configured to activate at different times for
adjustable durations. These tones can be programmed to go off at a certain
time of the day, or periodically every hour or every minute.
