200e

Looking at the new 285e I am not sure I know the sonic difference 
between Ring Mod and Balanced Mod...I know what Ring Mod does. Also 
curious of the internal vs external reference functions: when set ot 
Internal does this provide an internal Modulator signal that can itself 
be FM/CV modulated or is this simply the wrong question to be 
asking...thanks.

AFAIK a ring modulator the simple passive circuit with a ring of
diodes and transformers and a balanced modulator is an active circuit
producing the same result at a far better signal to noise ratio often
referred to as a ring modulator as well. The effect is the same in
both cases.

285e has an internal sine modulator that can be replaced with an
externally applied modulator. The internal modulator can be frequency
modulated and controlled by CV.

The reason for the question came from the descriptive text on the 
285e page as follows..."A separate output is dedicated to classic 
ring modulation, a subset of balanced modulation." If they were 
identical this statement would not have much point....I guess, 
maybe....

I had always considered the terms Balanced Modulator and Ring  
Modulator synonyms, myself. I thought that this referred to circuits  
that created sum and difference tones, while suppressing the carrier &  
modulator, as opposed to AM where the carrier is still present.

The 261e AM section goes from AM into ring modulation, so I imagine  
that the 285e circuit does something similar

Yes, there is an internal oscillator (actually two: one for the freq  
shifter and one for the balanced mod section), which can be pitched  
around and FMed.

I'd be interested in the definitive answer to this too.  My guess is that it allows you to vary 
continuously from DC-coupled to AC-coupled modulation, with varies the extent to which 
the carrier frequency is suppressed (i.e. difference between AM and classic 'ring 
modulation' which has only the sidebands).  But this is just a guess!
