How to connect the 7050A subwoofer to my 8030A's / 8130A's?
There is only one way to connect the stereo 7050A (discontinued) subwoofer with a pair of 8030A's, 8130A's or discontinued 8020A's or 1029A's.
: Do not forget to turn “ON” the "BASS ROLL-OFF" dip switch (switch 2) on all main loudspeakers (8030A
’s). This switch actuates an 85 Hz high-pass filter on the main loudspeakers matching them to the main low-pass filtered channels of the 7050A.
