PA•1 Passive / Active Preamplifier

retail price $599

The PA•1 Line Stage uses a simple design, combining both passive and active circuitry for the best compromise between sonic purity and needed gain.

The volume control works passively until the center detent is reached. At this point, the signal is coupled with a Class A, dual-mono amplifier for up to 6db gain. Unlike typical line stages, the PA•1 only amplifies the signal when gain is needed.

Connections include four inputs, one tape/processor loop and two pair of outputs.

PS•2 Phono Preamplifier

retail price $599

The new PS•2 Phono Stage is our "New & Improved" version of the highly acclaimed PS•1. Key components have been upgraded for even better performance and gain has been increased for use with extremely low output moving coil cartridges. Rear panel DIP switches are used to select settings for resistive load, capacitance, gain and subsonic filter. This flexibility allows for use with almost any line stage and MM/MC phono cartridge. The new PS•2 will feel right at home matched with the best of turntable/cartridge combinations.
