Carver Amazing Line Source Speakers

Hi Ozzy,

It’s been a long time since I looked inside my unit, and I didn’t pay much attention to the jumpers when I did so. But based on what the manual says, yes, I would assume it has 8 jumpers. I do recall that the circuit board in mine says HDP-4, as you found also. (Mine has a separate circuit board in addition, which provides the processing for the HDP-5’s touchscreen, its ethernet interface, and perhaps some other functions that are not included in the Premate).

The instructions shows all 6 on the outputs. But, it also shows using 2 on the RCA input section. I have a total of 6 of the jumpers to use.

I’m looking at the latest version of the manual ("Rev 1, applies to DEQX-Cal version 3.02"). Since that manual applies to your Premate as well as to my HDP-5 and to other models, and the same board is used in both of our units, but the Premate provides two stereo pairs of outputs while the HDP-5 provides three, it seems evident that only 4 of the 6 output jumpers shown in the manual are necessary for the Premate. And therefore perhaps only those 4 (plus the two on the inputs) were provided initially.

The jumpers were originally only on the mid and bass outputs. There was none on the high outputs and 2 were used on the RCA input section.

Since the two sets of outputs on your unit are identified on the rear panel as being for mains and subs, I would have thought that the way you originally found the jumpers to have been placed (mid and bass, plus two for the RCA analog inputs) would have been correct.

So as I said in my previous post I’m puzzled. It sounds like the way you found all of the jumpers initially was exactly where I would have expected them to be in the Premate.

almarg,

Thanks but no the high- output needs the jumpers in place. Without them the DEQX unit will output considerable hiss through the balanced outputs. But, perhaps the mid jumpers are not needed with my model.

I sent a email to DEQX on Sunday asking for advise. I hope they answer.

I just noticed that on the rear panel of the Premate the "main" outputs are also identified as L2/R2, and the "sub" outputs as L1/R1. And the jumper block information on page 166 of the manual of course uses L and R designations, rather than bass, mids, and highs.

So when you referred to the jumpers initially being on the mids and bass, are you sure that they were on L1/R1 and L2/R2, as opposed to L3/R3 and L2/R2?

almarg,

Inside my DEQX Premate unit the jumpers are labeled as; R bass, L bass, R mid, L mid, R high, L high.
On the back of the unit the outputs are labeled as you say which also corresponds to the DEQX home screen.
Confusing? So is the manual...

All I can say is with the output jumpers on all 3 output sections the balanced out plays dead quite. Removing the high jumpers introduces very high hiss with the balanced out.

Ozzy, your experience with the Carver amp reminds me of mine with my Carver Cherry 180 amp. I bought it around 9 years ago. I bought a new custom speaker and started to drive it with the Carver. However, the bass sounded weak and the bias meter would go back and forth full sweep like crazy with bass transients. I thought there was something wrong with the amp. I called Bob, and he told me unequivocally it’s not the amp but the speakers. Well, he was right. The speaker designer reversed the mid/bass crossover with the tweeter section. I’ve also called him with other issues and he always came up with an answer to fix it. He’s like no other designer I know.
