REAR-PANEL APPOINTMENTS

Antenna Inputs:
50-ohm (N)

Digital Line Output:
The AES3 (XLR) stereo output is a 24-bit

48kHz output that may be adjusted between –30dBFS and 0dBFS

corresponding to ±75kHz carrier deviation

with or without de-emphasis.

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:
The unbalanced (BNC) output may be adjusted between 1V p-p and 6V p-p

corresponding to ±75kHz carrier deviation. Source impedance is 75 ohms.

Composite Audio Processing:
Up to 3dB of composite clipping may be applied to the composite/MPX output to better define the FM deviation limit. The 19kHz stereo pilot and the 57kHz RDS subcarrier are stripped

filtered and reinserted after the clipper. This clipping feature does not affect the demodulated L/R program outputs.

Network Port:
An RJ45 jack accepts TCP/IP network connections for remote setup and operation of the AARON 640.

Headphone Jack (Front Panel):
A quarter-inch (TRS) headphone jack mon- itors the off-air program signal. Head- phone volume is a menu item.

THE USER INTERFACE

Front-Panel:
A front-panel graphic display and jog wheel allow easy

menu-guided in-situ setup and operation of the AARON 640. LED “VU” meters display L/R program audio levels.

Software Control:
The IP network port enables complete remote setup and operation of the AARON 640 over a local network or the Internet using any Desktop

tablet or mobile browser.

SNMP:
SNMP remote monitoring supported.
