Zumbini-

I know this is an old post, but any chance you could please put up a pic of the silkscreened diagram for mono connection that's on the back of your M-1.5t?

Sounds like you've got them "strapped" in parallel mono. That must sound terrific!

When I posted this I was feeding one channel of each M-1.5t to take advantage of "power steering" (drawing power from the unused channel).

BTW: Those amps have long since been replaced with a pair of M-500t's (refurbed by BillD) with each amp driving one subwoofer in bridged mono.

Thank you very much! Folks ought to call you "Quick Pic Zumbini", you're always ready with a helpful illustration! 8)

I was confused, because you were driving both channels and using the opposite channel's ground(black) terminal. I believe neither of which should be neessary (or have any effect).

Parallel mono has advantages, but also pitfalls! I'm also more inclined to run with just one channel, unless the load tends to low impedance.

I was confused too Phil #-o (about needing to feed both channels).

Using the opposite channel ground was necessary because the "correct" binding post was damaged. No biggie since it's a common ground amp.

Thanks, it all makes sense now! :)

Those binding posts really were a weak point on those models. I never had a problem with the ones on my TFM-45's, so they must have listened to the customers who clamored for an improvement.

I briefly toyed with the idea of running bridged M-1.5t's (series bridged with simple mods), but then I decided to go with PM-1.5a's instead - younger, tougher, slightly more power, lots more features, but still with the Anthracite look I wanted. Still, I'm finding it difficult to give up my remaining M-1.5t, she's so stately with her bold and simple face...

And nice rack! =D>

Now i am a little lost . Do the 1.5 amps not share a common ground? And if they do, why would you not invert one channel input and then feed off both positive outputs with one being ground due to the invert? Or if you are using the ground of one channel and simply using a y adaptor, then that would mean that one channel is inverted at the inputs and outputs? Are these the amps that have issue running polk sda type speakers?

Oh, i missed that. So, then all you have is one channel with a touch more headroom right?

I recapped both of my M-1.5t's a few years ago. Kept one as a spare and gave the other to my son for his system (M-1.5t/CT-7/DTL-200MK2).

I agree with your assessment of the pro version. I'm using 3 PM-1200's in my PA rack (along with a PT2400) and they kick ass.

That's correct Angelo. The owner's manual suggests about 30% more power is available that way, up to the limit of the power supply (1200W)

Thanks Angelo. It's not perfect (yet) but it'll do in a pinch. :lol:

I have considerably more LPs in another rack in the next room.
