    Balanced/Unbalanced to balanced/unbalanced stereo preamplifier assembled !

    This is a preamplifier with Balanced/unbalanced input and balanced/unbalanced output for all combination of transforming between unbalanced and balanced audio configuration. Thus, it can do the below functions :

    Balanced input -> balanced output ;

    balanced input -> unbalanced output ;

    unbalanced input -> balanced output ;

    unbalanced input -> unbalanced output.

    Each channel contains a new old stock signetics/Philips NE5532 for low noise /low distortion signal processing. The opamps can be easily replaced by other dual opamps easily via the IC sockets.All the resistors are low noise, low tempco, 1% tolerance metal film resistors. The balanced input/outpu Cannon sockets are already mounted on the board. For the unbalanced input/output, simple 2-pin PCB board terminals are mounted on the board. The whole assembly can be seen in the pictures.

    The default voltage gain is one.

    PCB thickness : 2.0mm board

    Copper thickness : 75um( four times normal thickness !!)

    Board Dimension : 103mm x 63mm.

    Supply voltage : DC +/-15V

    We do air shipping worldwide at US$6.00.
