The Model 7602 MKII is the sequel to our smash hit 7602 Microphone Preamplifier/Equalizer. The 7602 MKII new features include: selectable mic impedance, LED input metering, upgraded knob styles, and two different power options--all of this for the same price as the original unit. The 7602 MKII ships with an inline power transformer (all regulation is done inside the unit). The rackmountable CPS-1 can also still be used, but is no longer required.

The Model 7602 MKII Microphone Preamplifier/Equalizer is based on a classic and revered design utilizing pure Class ‘A’ circuitry. This unit is made with 100% discrete components, hand wound transformers and was fabricated to precisely match vintage counterparts manufactured in the early to mid 70’s. The Model 7602 MKII represents a dramatic breakthrough in delivering vintage audio performance at an affordable price.

Equalizer Section (Selectable 3 band design with a flexible filter section)

Filter - This is a high pass filter with 3db loss at 300Hz, 160Hz, 80Hz, and 50Hz with an 18db cut per octave slope.

Low Equalization - This section has a shelving slope with four frequency selections: 220Hz, 110Hz, 60Hz, and 35Hz. This equalizer affects the selected frequency and all others below it. The gain control provides 20db of boost or cut.

Mid Equalization - This section has a peaking characteristic with six frequency selections: 360Hz, 700Hz, 1.6k, 3.2k, 4.8k, and 7.2k. The gain control provides 20db of boost or cut.

High Equalization - This section has a shelving characteristic with five frequency selections: 16k, 12k, 7k, 4.9k and 3.4k. This section adjusts the selected frequency and all others above it. The gain control provides 20db of boost or cut.
