The P9 is a two channel, four bands EQ. 2 bands are high and low shelving, and 2 bands are parametric mids. There are high and low pass filters on each channel.

The first major difference with the P9 from other EQs from the outside is that none of the controls are potentiometers (pots), they are all switches. This is a major feature of older equipment, that enables precise control over every parameter, and repeatability of results. Over the years, with things like EQ, pots have replaced switches to save on manufacturing costs, however, for the purist, pots can be very inaccurate and failure prone.

On the inside, the P9 features a classic design of EQ using inductors and vintage amplifiers. This design is an adaptation of Barry Porter’s classic that oozes musicality and richness. The amplifiers are pure class A, discrete that in themselves add a quality that is hard to define, yet unmistakable.
