Balanced to unbalanced

Balanced to unbalanced
Balanced signals can be converted to an unbalanced output signal. The BCF and Unbalancer perform this task well. The BCF receives a balanced input signal and converts it to an unbalanced output. It is a unity-gain buffer that offers a high input impedance, a low output impedance, low distortion, and great CMRR. The Unbalancer adds signal gain to the BCF.

Unbalancer Two
The Unbalancer-Two circuit accepts a balanced input signal and delivers an unbalanced, single-ended output. Besides performing the conversion from balanced to unbalanced, the circuit provides a little gain (usually, about 1.7 or +4.6dB) and exhibits an exemplary CMRR (Common Mode Rejection Ratio) and low output impedance.

Unbalancer
The Unbalancer is a tube-based, balanced-to-unbalanced converter that accepts a balanced input signal and puts out a single-ended, unbalanced signal, much like a Broskie cathode follower, but with gain. (In fact, a Broskie cathode follower is the output stage in the Unbalancer circuit.) The input stage is a differential amplifier with a constant-current source load on the coupled cathodes. Besides performing its unbalancing conversion, the Unbalancer circuit provides voltage gain and exhibits a fine CMRR.

BCF 9-Pin PCB & User Guide
The BCF receives a balanced input signal and converts it to an unbalanced output. It is a unity-gain buffer that offers a high input impedance, a low output impedance, low distortion, and great CMRR. In addition, because the BCF uses a push-pull topology, its use is not limited to line-stages, as the BCF can be used as a headphone buffer-amplifier if the headphone's impedance is high enough (say, 300-ohms).
