Dual Program Equalizer, passive filters with better phase coherence that active designs, and with inductors that offer a rich and smooth harmonic quality.
The Summit Audio EQP-200B Program Equalizer uses tube and solid state technologies to produce the warm sounds associated with tubes while providing the reliability of solid state devices. Based on a Pultec type design, the EQP-200B is a very musical sounding passive equalizer followed by a vacuum tube amplifier to overcome any gain loss. Connections are made by using three pin XLR connectors.
