Stereo Unbalanced to Balanced Audio Converter Adapter ULTRA LOW NOISE PCB ONLY
Description:
100% Brand New and High Quality
Note: this item is only one bare board, not contain other parts. we do not provide schematic.
This is the PCB 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 DRV134. 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 voltage: +/- 10V to + / - 15V (suggest +/- 12v)
The PCB has a board thickness of 1.6mm, and copper thickness of 70um. This is four times normal board copper thickness! The surface is gold plated and coated with two-sided solder resist for maximum durability.
PCB dimension: 52mm x 52mm
The circuit consists of 2 DRV134 and 4 10uF 35V e-cap and 4 0.luF 50v film cap for decoupling purpose. As the circuit is too simple we do not provide schematic.
