good idea....ruffrecords said:If your interface is electronically balanced then it may be that you are losing 6dB at the input to the unbalanced EQ. To recover it you could fit a 10K:10K isolating transformer at the EQ input. Then you could simply impedance balance the output without losing any signal level.

Realistic IIRC is a radio shack brand so not even semi-pro. What kind of connectors are on the inputs and outputs?
If two circuit like RCA, it is surely not differential.
FWIW some balanced output drivers sense for (single ended) grounded legs and adjust up the level on the other active leg.
Adding a differential input may be cheaper than adding a transformer, but a transformer is easier (and you can keep it after you replace the EQ).
