GENERAL PERFORMANCE Tuning Range: Extended FM band: 65.0MHz–108.0MHz Sensitivity/Noise Performance: Unweighted monaural SNR for AES Digital and L/R Analog line outputs referenced to ±75kHz carrier deviation at specified RF input levels >82dB Digital, >80dB Analog at 60dBμv >78dB Digital, >76dB Analog at 40dBμv >60dB Digital/Analog at 20dBμv >50dB Digital/Analog at 10dBμv >43dB Digital/Analog at 0dBμv Selectivity: Selectable IF bandwidths 311kHz, 287kHz, 254kHz, 236kHz, 217kHz, 200kHz, 184kHz, 168kHz, 151kHz, 133kHz, 114kHz, 97kHz, 84kHz, 72kHz, 64kHz and 56kHz Frequency Response: Composite/MPX Output (pass-through): ±0.5dB, 20Hz–100kHz AES Digital & L/R Analog Line Outputs: >±0.2dB, 20Hz–15kHz Stereo Separation (at 1kHz): Composite/MPX Output: >45dB in pass-through mode; >50dB in MPX-regeneration mode. AES Digital & L/R Analog Line Outputs: >50dB Program Signal Latency (Delay): Composite/MPX Output: <250μs in pass-through mode; <2.4ms in MPX-regeneration mode. AES Digital & L/R Analog Line Outputs: <2.4ms Regional Settings: Tuning Steps: 200kHz, 100kHz or 10kHz De-Emphasis (Line Outputs): 75μs or 50μs Radio Data System: RBDS or RDS 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. MISCELLANEOUS Test Tone Generator: 20Hz – 20kHz; 60dB attenuator. AC Mains Requirements: 90–130VAC or 200–255VAC, 50/60Hz; 5W.
