Just  as  with  the  Digital  Line  Output  discussed  above,

Unbalanced 

Operation 

To connect  the  analog  line  outputs  of  the  AARON 650  to  the 

low-level,  unbalanced  inputs  of  consumer-grade  equipment,  

connect the center conductor of the shielded output lead to Pin 

2  of  the  XLR  connector,  and  the  shield  to  Pin  1.    Leave  Pin  3  

floating (unconnected).   

When  driving  unbalanced  lines  the  actual  output  level  will  be

 

6dB lower

 than the 

Analog Level

 shown in the 

Analog

 

Audio Output

 

menu, as only one side of the bridge-configuration output am-

plifier is driving the line. 

COMPOSITE/MPX OUTPUTS 

There are two independent composite/MPX outputs on the rear 

panel  of  the  AARON  650:  

MPX  OUT  1

 and 

MPX  OUT  2

.  These 

are unbalanced BNC connectors with a resistive source imped-

ance of 75 ohms. 
The levels of the composite/MPX signals may be independently 

adjusted under the 

Setup / MPX Output

 menu.  The level in open-

circuit (unloaded) peak-to-peak volts is indicated in the menu, 

and can be adjusted between 1V p-p and 6V p-p, corresponding 

to ±75kHz deviation of the incoming carrier. 
The composite/MPX signal may optionally be subjected to 

composite  signal  processing  in  both  the  Pass-Through  and  the  

Stereo-Regen modes.  This optional processing of the compo-

site/MPX is discussed on Page 32, and will be loosely referred-

to as ‘audio processing.’  This will differentiate it from the sev-

eral RF signal processing options available under 

Reception Tools 

that may be called into play to improve reception under ad-

verse conditions.   

RDS DATA 

This USB ‘B’ socket provides a ‘raw’ RDS data stream from the 

tuned station.  A simple software routine that will allow further 

analysis and archiving of these data may be downloaded from 

the Inovonics Website. 

NETWORK PORT 

A  standard  RJ-45  network  jack  is  used  to  connect  the  AARON  

650  to  a  Local  Area  Network  (LAN)  or  to  the  Internet.    Full  re-

mote control and off-air monitoring of the receiver is afforded 

via the internal Webpage interface.  Networking setup and Web-

based operation is explained in Sections IV and V.
