Hello,
Been reading this forum for months now, and finally got around to posting.
I've recently treated myself to a Peavey PR-15P PA powered speaker, to use as a monitor for my TD-12 and one day something to practise/gig with.
Very impressed, very low-level hiss, and terrific punchy bass, unfortunately due to the neighbours, I can't turn the volume past 2, let alone up to 11!
The problem I've got is that when running the TD-12 though the amp, I'm getting an audible hum. I only get this hum when running the TD-12 in, so it's obviously not a problem with the Active Speaker. This just leaves the TD-12.
The amp is wired up via the master out, left into one input and right into the other input, each input is mixed and fed into the active speaker amp.
I get no hum (from my headphones) if I plug my headphones into the master out. I do get hum if I plug the patch lead into line in (just investigating..).
Measuring the AC voltage between the ground on the speaker and the ground on the TD-12 brings up ~8V, which is not enough to be audible, I believe.
The cables are standard "good quality" mono shielded cables, and I've played around with some others, no change..
I can obviously live with this hum (but why should I?), since the speakers are turned way down, but if I wanted to crank them up, this hum would be quite noticeable!
Any ideas what my next check is?
How do people connect their TD-12 to their active speakers? I've only got one speaker, so I only need one input, but I like the stereo separation in my headphones and rapidly switch between the two. So don't really want to compromise here.
Is running left and right into 2 of the active speakers three inputs correct, or will there be some phasing/distortion problems?
Cheers
Jonathan
