19.1  CHANGING THE INPUT AUDIO IMPEDANCE (

FM

 VERSION) 

 

The analog input impedance may be set to 600Ohm, rather than 10kOhm, by moving the two jumpers JP1 and 

JP2 on the analog input board (see figure below). 

 

 

 

19.2  CHANGING THE INPUT AUDIO IMPEDANCE (

ST 

VERSION) 

 

The analog input impedance may be set to 600Ohm, rather than 10kOhm, by moving the two jumpers J6 and J7 

on the analog input board (see figure below) to the right-hand position.
