The Model 5330’s five outputs have a nomi-
nal signal level of +4 dBu and a maximum
output level of +24 dBu. The outputs are
electronically balanced, capacitor-coupled,
and ESD (static) protected. They are com-
patible with virtually all balanced and un-
balanced 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 espe-
cially useful in applications where powered
party-line (PL) or talent-cueing (IFB) circuits
may be present.
Monitoring
A flexible yet easy-to-use monitor sec-
tion offers the ability to listen to and visu-
ally observe the level of the four input and
four output audio signals. Two pushbutton
switches allow a user to select which au-
dio 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 channels. 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 se-
lected for monitoring. The meters are cali-
brated 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 loud-
speakers or a power amplifier associated
with monitor loudspeakers. Two rotary
controls allow the levels of the headphone
and monitor outputs to be independently
adjusted.
Simple Installation
The Model 5330 is housed in a lightweight
aluminum enclosure and mounts in one
space (1U) of a standard 19-inch rack
enclosure. The unit uses standard connec-
tors to allow fast and convenient intercon-
nections. This includes 3-conductor male
and female XLR connectors, 3.5 mm and
¼-inch jacks, and an IEC C14 receptacle
for mains power. The unit connects to
a local area network (LAN) using a stan-
dard RJ45 receptacle and supports
100 Mb/s twisted-pair Ethernet. Four
LEDs on the back panel display the status
of the Ethernet connection and Dante in-
terface. The Model 5330 requires 100-240
volts, 50/60 Hz mains power for operation.
Future Capabilities and
Firmware Updating
The Model 5330 was designed so that
its performance and capabilities can be
enhanced in the future. A USB receptacle,
accessible on the unit’s back panel, al-
lows the application firmware (embedded
software) to be updated using a USB flash
drive. To implement its Dante interface
the Model 5330 uses one of Audinate’s
4-in/4-out Ultimo™ integrated circuit. The
firmware in this integrated circuit can be
updated via the unit’s Ethernet connection,
helping to ensure that its Dante capabilities
remain up to date.
