SOURCE: i have a yamaha nx sw150 subwoofer that i want to

Parts from all-in-one packages like this aren't inended to be pieced out to other applications. Proprietary connections are a huge clue and disincentive.

A look at other Fixya queries gives this answer:

"I have this sub. The system connector jack needs a 12V DC signal to turn on. If you don't have a suitable Yamaha receiver with this connection, use any 12 V DC adapter with a 1/8 in mono plug (the tip should be positive)."

I imagine the subwoofer could be opened up and whatever circuitry is enabled by the Control signal could simply be jumpered "true" so it is always ON. That would mean the amp would be drawing power at all times, though.

SOURCE: my wharfedale sw150 subwoofer cuts out in normal viewing, any suggestions

If your Wharfedale sub is powered, it gets its input from a subwoofer output on the rear of the Sony. At a certain level, your sub is turned on and sounds just fine until the level decreases during quiet passages of music then it turns off. I believe the theory is that this approach prevents start-up "pops" but in practice it is a poor solution. I have had several subs that have acted this way. I don't know of a way to fix this short of eliminating the level-controlled turn-on circuit

What remote code should I use to control the YSP 2500 from a universal remote control?

Sound bars tend to use unique remotes, probably to prevent undesired interaction with other remotes.

Power Subwoofer doesn't work

Two possibilities:
1. Your source material does not contain bass frequencies.
2. Your SUBWOOFER SET - BASS OUT is set to Front, rather than SWFR (subwoofer). See page 63 of the manual.

Let me know if that helps.
