level of the auxiliary output will be +4 dBu,
assuming that the selected Dante input (re-
ceiver) source observes a –20 dBFS nomi-
nal level. A Dante source signal with a level
of –20 dBFS will always result in a +4 dBu
signal level on the auxiliary output. There is
no specific level indicator or monitor func-
tion associated with the auxiliary output.
This is not a limitation as each of the pos-
sible audio sources (outputs 1-4) can be
independently monitored for level and audio
quality.
Monitor Section
The monitor section provides users with
the ability to listen to and visually observe
the level of the audio signals that are asso-
ciated with the four input channels and the
four output channels. Eight green LEDs
indicate which source or sources are ac-
tively being monitored. Two pushbutton
switches allow users to select the input
source(s) to be monitored. A mode selec-
tion allows either a single audio channel or
a pair of audio channels to be monitored.
A 2-channel (stereo) analog output, located
on the back panel, can be connected to
inputs on amplified speakers or an audio
power amplifier. In addition, a 2-channel
(stereo) headphone output is accessible
on the front panel by way of 3-conductor
(stereo) 3.5 mm and 3-conductor (stereo)
¼-inch output jacks. Separate rotary level
controls allow independent adjustment of
the monitor and headphone output levels.
Two 8-segment LED meters display the
level of the signal or signals selected for
monitoring. The meters, calibrated in dBFS,
display the level of the selected signal(s) as
they exist in the digital domain. The meter’s
two yellow LEDs will only light when sig-
nal levels are in the range that’s typically
considered to be headroom. This could be
thought of as the area above the typical
Dante nominal level of –20 dBFS. Caution
must be observed whenever a meter’s red
LED lights. This would indicate that there
is little or no headroom left and that signal
“clipping” may be taking place.
As previously mentioned, two rotary con-
trols allow independent adjustment of the
monitor and headphone output levels.
These controls are “push-in/push-out” type
which allows its associated knob to be in
its “out” position when adjusting a level
and placed in its “in” position when protec-
tion from an unwanted change is desired.
Note that audio signals do not pass directly
through the level controls. Their position is
recognized by the Model 5330’s processor
which in turn adjusts the signal levels within
