Two channel, stereo matched microphone preamplifier uncompromised in sonic character, technical specification, and mechanical workmanship. Combining a precisely matched quartet of discrete low noise bipolar transistors in a full symmetrical (balanced) input circuitry with a laser trimmed DC coupled BiFET output driver stage, in a differential topology which delivers extremely wide dynamic range, intended for demanding acoustic work. Uncompromising circuit design with meticulous selection and hand-matching of critical components assures consistently transparent audio performance at all dynamic excursions and frequency extensions.

Quality at an affordable price.

An equipment entirely hand-crafted.

The components used are all selected with the strictest tolerance, and tested by ear.
