dBu (unloaded) notation next to the adjusting sliders on LCD-
touchscreen or Webpage
Setup
menus.
Although seldom seen in modern times, a legacy 600-ohm-
terminating load will drop the actual dBm level 2.5dB below the
figure shown beside the associated slider.
An unbalanced output should be taken from the ‘hot’ or ‘+’ side
of any analog output and ground, leaving the ‘return’ or ‘–’ side
of the output floating. The unbalanced output level will be 6dB
below the figure shown beside the slider.
Analog levels may be set to any figure between –15dBu and
+15dBu, corresponding to 100% (±75kHz) deviation of a mon-
aural FM carrier. The default setting is +4dBu.
AES Digital
Line Output
The
AES DIGITAL OUTPUT
delivers balanced, transformer-
coupled AES3 digital stereo program audio from a source im-
pedance of 110 ohms. This is a 24-bit output at a selectable
sample rate of 44.1kHz or 48kHz.
AES-digital sample rate and levels may be set under LCD-
touchscreen or Webpage Setup menus. Levels may be varied be-
tween –30dBFS and 0dBFS, corresponding to 100% (±75kHz)
carrier deviation. The default setting is –10dBFS.
AoIP Streaming
Port and Levels
The Dante-compliant AoIP (Audio over Internet Protocol) out-
puts appear at the rear-panel RJ45
AoIP PORT
. This port is in-
dependent of the
LAN PORT
network connection and its ‘casual
streaming’ utility.
Dante/AoIP streaming first requires basic Dante setup under
the Webpage or LCD
Dante
menus as detailed on Pageg 42-43.
Output levels are adjusted on the Setup / MPX and Audio Outputs /
Dante Output Webpage, or under the LCD Setup / Dante Outputs
menu. The dB notation beside each slider control corresponds
to the level of program peaks at 100% FM modulation. These
are adjustable between
0dBFS
and
–30dBFS
; the default setting
is
–10dBFS
.
LAN Network
Port
The RJ45
LAN PORT
connects the 541 to a Local Area Network
(LAN) or the Internet. Network setup is under the Webpage or
LCD
Network
menu and detailed later in the appropriate section.
Networking enables remote control, full SNMP functionality,
and the HTTP/UDP Web-browser ‘casual listening’ utility.
GPOs
A removable screw-terminal strip on the rear panel accesses six
GENERAL PURPOSE OUTPUTS
(GPO) terminals, the alarm out-
put ‘tallies.’ GPOs are NPN transistors that saturate to ground
and can sink up to 100mA at up to 40V. Alarm polarity (active
ground or active open) is software-programmable. GPOs may
be assigned to the various reception and program-fault alarms
as detailed on Pages 40-41.
