Four Analog Inputs
The Model 5330’s four inputs allow connection to
a range of unbalanced and balanced analog audio
sources. Inputs 1 and 2 have a nominal level of –10 dBu
and are intended for use with unbalanced sources asso-
ciated with personal electronic devices such as phones,
tablet and notebook computers. For easy access a
3.5 mm 3-conductor (stereo) jack is provided on the
front panel. A rotary level control, located adjacent to
the input jack, allows adjustment of the input sensitivity
to match a wide range of audio sources. This allows the
audio quality to easily be optimized. Inputs 3 and 4 are
electronically balanced with a nominal level of +4 dBu.
They use two 3-pin female XLR connectors which are
located on the unit’s back panel. They are intended for
connection to professional audio sources such as audio
consoles, wireless microphone receivers, and video
playback equipment.
The four inputs are capacitor-coupled and ESD (static)
protected to provide reliable operation in a variety of
demanding applications. Extensive filtering minimizes
the chance that radio frequency (RF) energy will cause
interference. Low-noise, low-distortion, and wide
dynamic-range circuitry ensures that audio quality is
preserved. Four bi-color signal present/peak LEDs
provide a simple means of observing input activity. The
analog input audio is routed to high-performance ana
-
log-to-digital conversion (ADC) integrated circuits that
support sampling rates of 44.1 and 48 kHz with a bit
depth of up to 24. The audio signals, now in the digital
domain, are connected to the Dante interface where
the data is packetized and prepared for transport over
Ethernet. The Dante Controller software application will
typically be used to assign the Model 5330’s four output
(transmitter) channels to inputs (receiver) channels on
designated Dante equipment.
Five Analog Outputs
The Model 5330 provides five analog line-level outputs,
four main and one auxiliary. The unit’s four Dante input
(receiver) channels serve as the audio sources for the
five outputs. The Dante Controller software applica
-
tion can be used to route (subscribe) Dante sources
(transmitters) to the Model 5330’s four Dante inputs
(receivers). The unit’s four Dante input (receiver) chan

nels are “mapped” one-to-one with the four main output

channels. Four bi-color LEDs provide a signal present/
peak indication of level of the four Dante input (receiver)
channels. The audio source for the auxiliary output is
selected by the user from among the four Dante input
(receiver) channels. Two pushbutton switches and four
LEDs, located on the front panel, allow for simple source
selection.
The Model 5330’s five outputs have a nominal sig
-
nal level of +4 dBu and a maximum output level of
+24 dBu. The outputs are electronically balanced, ca
-
pacitor-coupled, and ESD (static) protected. They are
compatible with virtually all balanced and unbalanced
loads with an impedance of 2 k ohms or greater. High-
quality components, including the important digital-to-
analog converter (DAC) integrated circuits, are used to
provide low-distortion, low-noise, and sonically-excellent
performance. Robust circuitry provides protection from
damage should a moderate DC voltage be accidentally
connected, something especially useful in applic
ations
where powered party-line (PL) or talent-cueing (IFB)
circuits may be present.
Monitoring
A flexible yet easy-to-use monitor section offers the
ability to listen to and visually observe the level of the
four input and four output audio signals. Two pushbutton
switches allow a user to select which audio source or
sources are to be monitored over headphones and/or
loudspeakers. A configuration choice allows monitoring
of either a single audio channel or a pair of audio chan
-
nels. This mode choice can be valuable when monitoring
monaural (single-channel) and stereo (dual-channel)
signals. Two 8-segment LED meters display the level of
the source or sources that are selected for monitoring.
The meters are calibrated in dBFS, directly reflecting
the digital signal levels of the Dante output (transmit
-
ter) and input (receiver) channels.
A 2-channel (stereo) headphone output allows support
for stereo headphone or ear buds. For convenience
both 3.5 mm and ¼-inch 3-conductor (stereo) phone
jacks are provided. In addition, a separate 2-channel
(stereo) monitor output allows interfacing with inputs on
amplified loudspeakers or a power amplifier associated
with monitor loudspeakers. Two rotary controls allow
the levels of the headphone and monitor outputs to be
independently adjusted.
