The XLR – male connector facilitates a passive loop-through of the AES signal to other apparatus. Hence the 
instrument is fitted with a switch able input termination. If the loop-through output is not being used, the switch 
(positioned between the two connectors) should be in the 110 

Ώ

 position. 

 
Power connector. 
 
Power is supplied through the coaxial low voltage socket. A mating connector should have an outher diameter of 
5.5mm and a hole diameter of 2.1mm. Either a 24V dc or a 18V ac sypply should be used.  
 
 
 
 
 

Remote Control. 

 
Remote control and additional power connection is accessible through the 9pole male D-sub connector on the rear side. 
 
Pin connections: 

Remote control #1 (RC#1)

 

Power input (24V dc or 18V ac)

 

Supply GND 

 

Remote control #3 (RC#3)
