Balanced Line Receiver
These days you shouldn't settle on a balanced line receiver without looking at the InGenius 1200 series from THAT Corporation. Its patented topology provides what no other electronic input stage can: true insensitivity to the small impedance imbalances that can render conventional line receivers ineffective in real world situations.
Or check out THAT's 1240 series. You will find not just drop-in replacements for other 0dB and -6dB line receivers, but a -3dB version as well. Do the maths! You'll see that with many applications, -3dB provides additional dynamic range with no head room penalty whatsoever. Now that's some clear thinking...
Unbalanced figure below is typical for 600 ohm differential source impedance mismatch.
