Older receiver, subwoofer out? (1 Viewer)

[BlakeH]

I have an older receiver, it's a Yamaha. I also have a powered subwoofer. It does not have the subwoofer out, but I'm wondering if it might have been labeled something else on older receivers that would still give it's powered ability?

Ugh, forgot to mention that it does support Dolby ProLogic. However, it does NOT support DD, or DTS.

please help.

The only reason current receivers have subwoofer outputs is that the dolby 5.1 has a channel for the subwoofer. Pro Logic has no subwoofer channel, and unless Yamaha added some proprietary decoding, you are (semi) out of luck. It looks like you have to go line or speaker level inputs.

My older sony receiver has a mono out that I use to hook up my subwoofer. If yours doesn't, using left and right preouts and running your other speakers small could be used. If you don't have preouts, use the speaker level inputs on your sub.

Note: using the speaker level connection does not make the sub passive, and draw power from the reciever. The conection is high impedence, and will not affect your receiver.
