Analog Inputs
The Model 5330 provides four inputs that
are intended for connection to line-level
analog audio signal sources. Inputs 1 and
2 are accessible on the front panel and are
intended for connection to a 3-conductor
3.5 mm plug that is associated with an
unbalanced 2-channel (stereo) source.
Inputs 3 and 4 utilize 3-pin female XLR
connectors that are located on the back
panel.
Inputs 1 and 2
On the front panel one 3-conductor
(stereo) 3.5 mm jack provides access to
inputs 1 and 2. These inputs are analog,
unbalanced, and have a nominal level of
–10 dBu. They are primarily intended for
interconnection with a stereo audio signal
provided by a personal audio device. A
3-conductor audio patch cord with a 3.5 mm
plug on its end will typically be used to mate
with the Model 5330’s jack. It’s expected that
in many applications the connection made
to the front-panel inputs will be temporary,
varying “day-to-day” as applications change.
As such, although acceptable, permanent
wiring to the 3.5 mm jack associated with
inputs 1 and 2 is not expected to be made.
Inputs 3 and 4
Inputs 3 and 4 are located on the back
panel and utilize two 3-pin female XLR con-
nectors. They are electronically-balanced
(differential), capacitor-coupled, and have
a nominal level of +4 dBu. Prepare 3-pin
male XLR mating connectors such that
pin 2 carries signal high (+), pin 3 carries
signal low (–), and pin 1 is common/shield.
Unbalanced sources can also be success-
fully interfaced with these inputs. With an
unbalanced source begin by connecting
signal high (+) to pin 2 and signal low/shield
(–) to both pins 1 and 3. If this provides a
“clean” signal interconnection then all is
well. However, if this results in hum or noise
on the associated line input, try connecting
signal high (+) to pin 2 and signal low/shield
(–) only to pin 3; leave pin 1 unconnected
(“floating”).

Analog Outputs
The Model 5330 provides seven analog,
electronically-balanced line-level outputs.
They all utilize 3-pin male XLR connectors
which are located on the unit’s back panel.
The seven outputs consist of main outputs
1-4, the auxiliary output, and monitor out-
puts 1 and 2.
