Thread: TT 8J : Concert v's Pioneer + Bose Conflict.

Hi all, new here so be kind!!

I've been having problems with my Bose amp. This amp has a 'C' at the end of the part number. I've bought a newer one with a 'D' suffix. Now then, the Pioneer I have will turn on the 'C' amp - but not the 'D', whereas the original Concert will switch them both on. Why?

When I split the plug apart and put the green plug to the Pioneer (with additional + & -) and plug the black into the Concert, the Pioneer plays superb....



Now... the adapter (which works with the old amp BTW) has these wires... Black -, Yellow +, Blue (amp +), Pink (tel mute)



And it doesn't have the wires for 'DI SENS', 'CAN/L' and 'CAN/H' as shown below....



....So what do they mean? The Concert is obviously switching the new amp on. How can I get around it?

Please Help!!!

The new amp will probably be switching using CAN rather than the DSP EIN feed... It is a difficult one to get around tho...
