Chameleon Labs 7602 MKII Mic-Pre & Equaliser

The Chameleon Labs 7602 MKII is the sequel to Chameleon labs 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 cost as the MKI. The 7602 MKII ships with an in-line power power supply (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 british design utilizing pure Class 'A' circuitry. This unit is made with 100% discrete components, hand wound transformers and was fabricated to precisely match the vintage counterparts manufactured in the early to mid 70's. The 7602 MKII represents a dramatic breakthrough in recreating vintage audio performance at an affordable price.
