Avedis Audio MA5 500-Series Class A Microphone Preamp

Avedis Audio's MA5 is a 500 series preamp that is modeled after classic 70's British consoles, but built with modern construction that's designed to last. Over a decade in production, the MA5 has stood the test of time and finds itself in studios all around the world. With good reason, the simple controls—Gain and Outputs—coupled with a few choice switches means you can spend more time listening to the sound and less time deciphering the front panel. Simple controls belie the complex circuitry and premium hardware contained within the MA5. A UK-made Carhill/St. Ives input transformer and custom made Jensen output transformer ensures great sound quality. The Gain rotary knob is stepped in 5dB increments and an Output level lets you fine tune the volume. Add reliability and high fidelity with the MA5 from Avedis Audio.
