Balanced power amp and subwoofer connection.

Hello.

Can any one tell me how to connect a powered sub to a balanced Pass amp. I understand that there is a issue with ground which means normal connection using a three wire Neutrik Speakon connection cannot be used. I know as I had damaged a Pass amp and a sub some years ago by following the instructions given to me by a the sub manufacturer ( MJ acoustics )telling me to connect the three speokon wires to the speaker posts on the amp. I took their advise as I assumed a sub manufacturer would know!

Pass are very vague and say I should contact the sub maker and the sub maker say I should refer to the amp maker!

Anyone done this and know the safe method? Can an av and hifi amp be connected to one sub designed for Hifi and home cinema amp connections at the same time. Or should this be for one reciever with stereo and hifi capalities?

Thank you

no, it a BK electronics, UK made, sub and XA30.5 power amp.

The MJ one was damaged and disposed of. Their quote for repair was too high and when I declined to have it repaired, they refused to send it back to me unrepaired and threatened legal action claiming I would try to sell it on an auction site as new which of cause is crazy. One call from my legal adviser had the dead unit back in two days. A very nasty company ! The unit was personally disposed of at a recycling centre.

Thanks.

Oddiofyly, would you let me know how the connection can be made using the pre. It has one set of XLR output ( in use in my case) and a set of RCA. Do I connect a single lead from one of the RCA outputs? Would the volume still be controlled? Thanks
