Retro - Balanced RIAA Stage
The Retro is a balanced input RIAA filter/gain stage for integrating vinyl into your balanced audio chain. There are two versions of the circuit:
Hi-Z is designed for higher-impedance MM cartridgesLow-Z is designed for low-impedance MC cartridges
The Retro uses Texas Instruments OPA1632 fully-differential and OPA-1642 JFet-input op-amps, low-noise Dale RN55/CMF55 resistors, Wima and Dayton Audio
polypropylene, and CD silver-mica capacitors.
While Retro is designed for balanced wiring of your cartridge, it will also support standard single-ended input wiring (by tying -IN to GND),
and still provide balanced output.
You can read more about the Retro module on
DIYAudio.
The Retro requires a 12-15V bipolar supply, such as our
LCBPS or
Placid HD BP.
