balanced zen line stage

supernet · 12th December 2001, 08:53 PM

What happen, if I solder short wire from -OUT (input stage of circuit) to ground and from -IN (output stage of the circuit) to ground? Will be result the same as with unbalanced Bride of zen?
I am asking this question, because I want to build a balanced DAC in the future, but now I am using unbalanced CD player and power amp.

It will work fine, but there is no particular
need to short the output.

Thank you, mr Pass for advice.

I"ve got very good potentiometer, which is made by Alps and rated at 25 kohm. Should I put it on input or output of the zen balanced circuit?

Probably input. 25K is a bit high for output, since
the output impedance will max out at about 6K ohm
