real ring wiring

real ring wiring

2007-01-18 by mudthumpertwine

Hi,
I just received my real ring modulator today, wired it up and
connected it to two outputs on my paia vco then out to an amp and just
got silence.
Now I'm very new to this so I just wanted to make sure that I am
wiring the jacks right.
I have 3 switchcraft type jacks(different that the box ones in ken's
diagram) that have 3 places to connect wires.
The first connects to the shaft where the plug enters so i figured
that is the ground or the equivalent of SL?
The other two connect to parts that are touching but when a plug
enters the one piece(A) is forced away from the other.
I am guessing that (A) is the equivalent of TP?
I've tried all sorts of wiring and the best i can get is that humming
that means something isn't grounded.
Any help would be much appreciated.

Also, my vco sounds weird now without the ring modulator attached.
I figured since this was a passive device, no harm would come from
trying different wiring out. Was this wrong to do?

-Jay

The one that is forced away should be TP (the TIP). The important thing is
it is the contact that stays touching the tip of the plug. The output must
be one of the outer pairs of connections.

If you shorted out the VCO douring your experiments it would not be good.
Also while the ring mod is a passive device, it is also a heavy load -
notably more so than most synth modules. If a synth module is designed
propperly, it will not have any permanent affect, but if a synth module is
poorly designed it is vaguely possible damage could occur, though I've not
heard of it happening with the real ring before.

If it any re-assurance, I often use the RRMod with my Paia 9700 series
VCOs. no problems.

Ok, so the TP wire is going to the tip contact and the SL wire
is going to the shaft or ground contact.
One output from each oscillator is plugged directly into the left
and middle jacks of the RRing.
The jack on the right is plugged directly to an amp.
There's still no sound.
Well if i turn the amp all the way up I can hear the two
original tones very faintly.
The VCO output is very high though.
I barely need the volume up at all on the amp to get
good levels normally.
I must be missing something very basic here.
Is there anything else involved?
thanks,

What you are doing sounds correct.

Check to see that a solder pad on the PCB hasn't lifted and that none of the
tracks have been broken while you were soldering.

Re: real ring wiring

2007-01-20 by mudthumpertwine

The tracks and soldering look good.
I'm not sure but I think there may be a problem with the transformers.

I tried holding the output plug against the soldered pins on the back
of the pcb while two different signals were connected to the
middle and right jacks.

I found that the 14 pins in the middle(8 from diodes and 3 from each
transformer) all produced the signal from the middle input.

The two pins on the right produced the signal connected to the right
jack while the two pins on the left were silent.

So it seems like the signals are unable to pass through the
transformers, hence no multiplying and no output.

Let me know if my logic is backwards.
This is all new to me.

I doubt it. They are all tested here before they leave.

These two pins would be the output.

with a signal at one end and nothing in the middle, see if you get a signal
on the other side of that same transformer. Turn it around and try it the
other way too (i.e. the other transformer).

I tried this and the signal is very faint.
I have to turn the volume of the speakers up
considerably to hear it and it doesn't show
up on my oscilloscope.

Re: real ring wiring

do you have a multimeter? Measure the coils of the transformers and tell me
what you get. Reading between the two pads one one side of the transformer.
Readings between the two outside pads on the 3 pads the other side, and
between the center and each side.

With the ohmmeter set to 20k i got the following..
.25 between the two pads on one side
.21 between the two outside pads of the three
.11 between the adjacent pads of the three
Is this what you are asking for?
I wasn't getting any readings with the voltmeter.

Exactly. If both transformers measured like this, they are both perfectly okay.

Which PAiA VCO are you using? The older ones (pre 9700 series) only put out
about 1/4 Volt peak-to-peak, which is not enough to get past the diodes. You
need a couple of volts output swing to drive a diode ring modulator, or
nothing will come out.

BTW, you can interchange one of the inputs with the output and take the
other input as the output - sounds slightly different but it works.
