rind mod idea

[Kristjan Varnik]

Hello,

I'm still recovering from that though u.s. loss yesterday.

I'm new to electroinics, but I'm trying to design a ring modulator
and have a couple questions.

I have a book based on the 747 op-amp. In the book
are small circuits for a summing amplifier and a differential amplifier.
I was thinking that I could combine these two circuits and mix the
outputs add a couple audio jacks and presto a genuine ring modulator,
none of that one-input ring-mod with an internal oscillator.

Now this seems almost too easy, so please tell me where I going 
wrong...

secondly, I was looking at a modulator system and saw what looked like
a mini-patchbay that was called multiples or multiplier...

could somebody explain what that is(I have a hunch) and 
if it's simple, how to put one together.

thanks in advance,
Kristjan
