Is the ring modulator volume non-zero?

The ring modulator outputs the sum and difference frequencies of all 
of the frequencies in the two oscillators. If the two oscillators are 
tuned to the same pitch, the ring modulator puts out a sound similar 
to a chorused version of an oscillator. 

Could this be it?
