I too can vouch for how amazing the OB/servo subs are.

If more manufacturers heard them, I suspect they would incorporate them in their designs, at a variety of price points.

Larry you a absolute right. It was therefore I bught mine, and hade shipped them to Denmark in me and my friend little company. We make ribbon / planer speakers. But we have a problem, the can't play down to 150-200Hz. Therefor we  are testing the GR/Rythmik with external digital X-over. As you say it is the best subs.

Thanks again!  What is connected to what in your system?  This is what I believe is happenning:

-Preamp out from your "main" preamp is connected to the stock input of your servo amp.
-From your servo amp, you have an RCA output (the green and yellow wires) that connect to your other bass amp.
-The on-off switch addition turns the servo amp on and off.
-The actual servo output / input is still connected to the SW-12-16FRs.
-All eq / crossover functionality is contained within the servo amp so that is completely bipassed when using this setup.  You can set whatever crossover you want as well as dial in the eq you want.

Does this sound correct?  Am I missing anything pertinent?

Thanks again!

Hey Jim.

Green     RCA +
yellow    RCA sleeve

The switch is to power on and off the amp.

In my case Brown on
                Orange off
                Black is connected by a resistor to the middle pole. I don't no the         
                value.
I`ts not my job it is a electronic man who have makes it for me. I only make ribbon speakers.

No. My preamp is also the digital X-over with 8 analog outputs and lots of analog and difrent digital inputs , i`ts like DEUX.
The to servo amps (left / right ) are connected to there own pre output channel.
The connection to the servo amp is the seprate RCA (the green and yellow wires). It is the input to the servo amp.

-The on-off switch addition turns the servo amp on and off. Yes
-The actual servo output / input is still connected to the SW-12-16FRs. Yes
-All eq / crossover functionality is contained within the servo amp so that is completely bipassed when using this setup.  You can set whatever crossover you want as well as dial in the eq you want. Thats right, there are no power more to the plateamp pre, or any connection between the servo amp and the pre and all function are bypassed. I don't no what happen with the servo if I make a crossover design very fare from what it is designed to. If you make the X-overpoint at 400Hz. or higher the woofers dosen`t  sound good. Right now my x-over is 300Hz. 96db slope, and I`am not finish the system have to been fine-tuned.

Your preamp is like a DEQX...so, is mine (an MBox 3 Pro) and I handle all eq / crossovers with my computer feeding the MBox.

I don't follow you on the connection scheme.  Can you outline it again (i.e., what plugs into what)?

Thanks again and sorry for being dense.

Is it the connection between preamp and the servo you don't understand, or the connection of wires? There are only one plug in use on the sub amp, and it is socket to the power cable. Non speaker terminal, RCA in and output, swiches are in use. There are no connection between the two sub amps (left and right channel).

Here is my pre.

It might be easiest if you post some pics of the various connections between the components so I can see what is connected to what.

Thanks again,

Jim I dont understand wich components you are tolking about. I had uploaded pics of the sub amp. The connection between the preamp and the sub amp is the same way to connect a normal mono amp. The only difrent here is, the connection is not to the standard input on the sub amp because those terminals are bypassed. Look at the pics and you can see the new connection from pre to sub amp.

Ok, so:

DCN28 -> Rythmik A370-PEQ (via RCA cable)

Rythmik A370-PEQ -> "new" SW-12-16FR amp (via newly made RCA cable using the green and yellow wires)
also
Rythmik A370-PEQ -> servo connection on the SW-12-16FR woofers

All eq'ing performed by DCN28 and the A370-PEQ plate amplifier is effectively bi-passed (except for the servo).

That should be correct based on what you explained, but please verify.

Thanks again,
Jim
