Main Outputs 1-4 and the Auxiliary Output
Main outputs 1-4 and the auxiliary output
are designed for general-purpose use which
could include connecting to analog inputs on
devices such as audio consoles, transmitters
associated with wireless in-ear monitors,
matrix intercom systems, or amplified speak-
ers. The circuitry associated with these
outputs is capacitor-coupled, electronically-
balanced (differential) and has a nominal
level of +4 dBu. The outputs have a source
impedance of 200 ohms and will perform
optimally when driving loads of 2 k (2000)
ohms or greater. The circuitry is capable
of providing a maximum output level of +24
dBu. This 20 dB of audio “headroom” means
that +24 dBu will be present on a line output
when its corresponding Dante input (receiv-
er) channel’s digital audio level is 0 dBFS.
No special precautions are necessary when
using these outputs in applications where
a variety of other specialized signals may
be present. The circuitry is protected from
damage in situations such as the accidental
interconnection with broadcast-type analog
party-line (PL) intercom or powered IFB (tal-
ent cuing) circuits or to microphone inputs
that have P48 phantom power present.
Five 3-pin male XLR connectors, located
on the Model 5330’s back panel, are provid-
ed for interfacing main outputs 1-4 and
the auxiliary output with associated equip-
ment. Prepare 3-pin female XLR mating
connectors such that pin 3 is signal high
(+), pin 2 is signal low (–), and pin 1 is com-
mon/shield. To connect to an unbalanced
load use pin 2 as signal high (+) and pin 1
as low/shield; do not connect anything to
pin 3. Do not connect (short) pins 3 to pins
1 on the mating connectors as this will
stress the output circuitry.
Monitor Outputs 1 and 2
Monitor outputs 1 and 2 are designed for
connection to inputs on audio power ampli-
fiers or amplified speakers. The circuitry is
identical in design and performance to that
used for main outputs 1-4 and the auxiliary
output. The one exception is the nominal
operating level is 0 dBu. Two 3-pin male
XLR connectors, located on the Model
5330’s back panel, are provided for inter-
facing with monitor outputs 1 and 2. Pre-
pare 3-pin female XLR mating connectors
such that pin 3 is signal high (+), pin 2 is
signal low (–), and pin 1 is common/shield.
To connect to an unbalanced load use
pin 2 as signal high (+) and pin 1 as low/
shield; do not connect anything to pin 3.
Do not connect (short) pins 3 to pins 1 on
the mating connectors as this will stress
the output circuitry.
