This is an assembled board of a very low distortion preamplifier ( Gain = 2) that can convert an unbalanced signal to a balanced signal.
The circuit make uses of a famous balanced line receiver DRV134PA per channel. The chip can offer a distortion as low as 0.0005% at 1KHz and 0.001% in the whole audio frequency band( below 18KHz) when driving 600ohm load ! Maximum swing can be 18Vrms at 0.01% distortion ! The gain is fixed at 6dB ( 2 times).
supply : +/-10v to +/-12v
pcb dimension: 52mm*52mm
Package including:
1pc Unbalanced to Balanced Output Board Low distortion DRV134PA x2 (assembled )
