REL B3 connecting to Linn Klimax Solo help...

Thanks Al, ill see how I go ;)

Hi Al, my Source has a dedicated plug for ground on its rear. I am using that. Without the use of that, the unit hums. I have also tried using one of the negative speaker wires - that appears to work.

I think the unit may be faulty as I get little to no output on any setting in any connection method.
I also live in Australia where we have 3 prong power plugs

Thanks

Hi Al,

The plug on the rear of the source (Klimax DS) is a dedicated ground that is to chassis. That is what I am using.

I actually think theres more wrong with the unit, I can barely get any output from the unit at any volume, any setting... The cone barely even moves...

This is playing a 20hz tone with REW. The gain is about 45%, push it to 50% and you can hear this awful noise

Hi Al,

I have connected the subs ground to the speaker lead and I get the horrible output noise with no cone movement at 45% gain... The unit under any connection method wont go over 45% gain. I did try 40 and 50 hz with the speaker lead connection. Same issue

The cone barely if at all moves on any setting. Spoke to the distributor who said there should be alot of cone movemen on either high level or low level inputs and that it appears faulty.

Hi Al

How do I do that on my pre, it has no ground plug....

Thanks Al, I understand now

Oh, how can I determine using a multi if its connected to circuit ground?? Ive never used one before.

Al, you're right it appears. I spoke to REL today who said the issue is a grounding one.

They sell a special cable for Class D power supplies (switch mode) to combat this problem.

It would appear, you're right in that the chassis ground is not common with the circuit.

So, back to the earth wire onto a RCA plug, are you sure that the RCA plug MUST be ground to the circuit????

If so, could I chop off a rca plug from a unused rca cable I have and solder this up?

IM going to measure it as you said now and see what occurs.

So I measured it, using a RCA plug outer and a chassis screw the result is 0. Does this mean I can use the earth wire to a chassis screw ?

I tried it anyway. Yes, the cone of the driver moves, but move the gain up above 50% and it makes this horrible noise.....

Assuming I cant use a chassis screw either.

Could I just try and Hold the earth wire onto the outta of an RCA plug to try it and see if that works???

Hi Al Does this help?

Klimax power amps have RCA shield connected to circuit ground which is lightly (~100R) connected to chassis.

The KDS (the source I used with the earth plug on the rear has transformer coupled outputs, so RCA shield is floating.

I still believe the unit is faulty because the gain at 50% shouldnt cause that sound I hear. Im taking it in this morning to get fully checked before I go further.

I think the chassis screw was indeed working and that the gain needed to be pushed more but couldnt because of a fault...

Cheers

At the shop now, we'll see what the story is. New cable is on its way! Ill report back with the results

Thanks for your help Al! :)

Update on this.

The cable is still making its way to me... but the repairer has found the driver is faulty. The magnet had dislodged itself from the unit... Thats what was making the horrible noise.

A replacement driver is funnily enough, in stock..

Soldered a RCA onto the Black wire as per your suggestion Almarg and the driver was replaced. All working nicely now ;) Thanks!!

Hi Guys,

Having another issue after moving house.

Speakon in the unbalanced connector, unit turns on, but no audible thump when its on and no signal via the RCA or Speakon cables...

Very odd. No dials changed in the move, packed and moved very carefully.

Blue power light comes on...

Any ideas?
