Program Audio Outputs:
‘Assignable’ outputs utilize XLR con-
nectors, ‘Dedicated’ outputs are RJ45
jacks per StudioHub® spec.
Balanced Analog:
(XLR) Left and Right
outputs adjustable from –15dBu to
+15dBu in 0.1dB steps; 200 source.
AES Digital:
(XLR) Adjustable from
RJ45 –30dBFS to 0dBFS in 0.1dB steps;
44.1kHz sample rate; 110 transform-
er-coupled.
Dante/AES67 Compatible:
(RJ45) Output
at 44.1kHz (Dante-only) or 44.1kHz/
48kHz (Dante /AES67); AoIP utility has
independent IP, Audio Format and
Transmit Flow settings; level adjustable
from –30dBFS to 0dBFS in 0.1dB steps.
Headphone Jack:
(¼” TRS) with adjustable
listening level.
Listening Stream:
Web browser remote-
listening stream employs HE-AACv2
encoding, 44.1kHz or 48kHz sample
rate, bit-rates from 18kbps to 64kbps;
accommodates up to 10 simultaneous
listeners. HTTP/Icecast and raw UDP
streams are available simultaneously.

19kHz stereo pilot sample; adjustable
from 1V
PP
to 6V
PP
in 0.01V steps.
LAN Port:
(RJ45) LAN connection to local network or
Internet provides remote monitoring, con-
trol, listening and full SNMP implementa-
tion; user-programmable network setup
and streaming parameters.
General Purpose Outputs:
(Barrier Strip) Ten
individual open-collector NPN transistor
closures to ground are associated with
alarm functions. Each is programmable
for GPO assignment and logic polarity.
Outputs sink 100mA, 40V
DC
max.
