541 TECHNICAL SPECIFICATIONS
PLEASE NOTE: Specifications tabulated here are ac-
tual, real-world measurements, not optimistic al-
lusions to theoretical ideals. Measurement results
should be repeatable when using the appropriate,
laboratory-grade test equipment.

(SMPTE, 60Hz/7kHz, 4:1).
Stereo Separation: >64dB, 20Hz-15kHz
FM Stereo Crosstalk (Main Sub or Sub Main) :
>67dB, 20Hz-15kHz,.
FM De-emphasis: 75µs / 50µs / None.
INPUTS, OUTPUTS AND PORTS
MPX Output: (BNC) select either MPX or 19kHz
stereo pilot sample; adjustable from 1V
PP
to
6V
PP
in 0.01V steps; ±0.25dB, 10Hz-100kHz.
Program Audio Outputs: May be assigned to the
FM-stereo program or to SCA audio. Unless
otherwise noted, performance parameters re-
flect FM Stereo Performance cited above.
Balanced Analog: (XLR) Left and Right outputs
adjustable from –15dBu to +15dBu in 0.1dB
steps; 200 resistive source.
Program Audio Outputs
(continued)
:
AES Digital: (XLR) Adjustable from –30dBFS to
0dBFS in 0.1dB steps; user-selected 44.1kHz
or 48kHz sample rate; 110 transformer-
coupled.
Dante/AES67 Compatible AoIP Port: (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.
UDP Stream: ADTS or ADTS in MPEG-TS
transport.
HTTP/Icecast ‘Casual’ 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 simultane-
ous listeners. HTTP/Icecast and raw UDP
streams are available simultaneously.
Headphone Jack: (¼” TRS) Menu-adjustable
listening level.
LAN Port: (RJ45) LAN connection to local net-
work or Internet provides remote monitor-
ing, control, listening and full SNMP imple-
mentation; user-programmable network
setup and streaming parameters.
General Purpose Outputs: (Barrier Strip) Six indi-
vidual open-collector NPN transistor closures
to ground are associated with alarm functions.
Each is programmable for GPO assignment and
logic polarity. Outputs sink 100mA, 40Vdc
max.
