REAR-PANEL APPOINTMENTS
Antenna Inputs:
Either of the two 50-ohm (N) inputs may be assigned to any station preset.
Digital Line Output:
The AES3 (XLR) 24-bit stereo output may be adjusted between –30dBFS and 0dBFS
,
corresponding to ±75kHz carrier deviation
,
with or without de-emphasis. The output sampling rate may be set to 32kHz
,
44.1kHz or 48kHz.
Analog Line Outputs:
Active balanced (XLR) outputs are adjustable between –20dBu and +18dBu (+15.5dBm)
,
corresponding to ±75kHz carrier deviation
,
with or without de- emphasis. Source impedance is 200 ohms.
Composite/MPX Outputs:
Two unbalanced (BNC) outputs are independently adjustable between 1V p-p and 6V p-p
,
corresponding to ±75kHz carrier deviation. Source impedance is 75 ohms.
USB Port:
Delivers raw RDS data for analysis.
Network Port:
An RJ45 jack accepts TCP/IP network con- nections for remote setup and operation of the AARON 650.
Headphone Jack (Front Panel):
A quarter-inch (TRS) headphone jack mon- itors the off-air program signal. Head- phone volume is a menu item.
FAILOVER AUDIO PROTECTION
Upon loss of the incoming carrier
,
loss of program audio
,
or RDS ‘hijacking
,
’ the off- air program may be replaced either with pre-recorded material on a plug-in SD card or a Web-streamed audio feed.
AUDIO PROCESSING FEATURES
In either the pass-through or MPX regeneration modes
,
up to 3dB of composite clipping may be engaged to better define the FM deviation limit. The 19kHz stereo pilot and the 57kHz RDS subcarrier are stripped
,
filtered and reinserted after the clipper.
THE USER INTERFACE
Front-Panel:
A front-panel graphic display and jog wheel allow easy
,
menu-guided in-situ
,
set- up and operation of the AARON 650. LED “VU” meters display L/R program audio levels.
Software Control:
The IP network port enables complete remote setup and operation of the AARON 650 over a local network or the Internet using any Desktop
,
tablet or mobile browser.
SNMP:
SNMP remote monitoring supported.
