I own a Bang & Olufsen 6000 quadraphonic turntable with MMC 6000 cartridge, both of these items were designed to work with CD4 records.
I have two quadraphonic receivers, one Marantz 4220 and a Sansui QR1500.
When I play records on both these via the B&O using either SQ or QS records everything is fine.
Recently I purchased a CD4 decoder, a JVC 4DD-5 which was brand new old stock, this came with all the low capaticance leads needed for connection.
I have to connect the 4 channel output of the decoder to the 4 channel aux input of the receiver. when playing a CD4 record however, I get severe distortion despite adjusting the settings of the decoder.
It appears that the cartridge is overloading the input on the receiver, does anyone have am possible solution to my problem.
