The MA5 is a high-quality 500 Series preamplifier that delivers the characteristic sound of early '70's British Class-A consoles. 

The MA5 is known for its full and open sound and rich harmonic content, particularly in the very low frequencies which reach below 10Hz.  Mids and Highs come through beautifully without sounding dull or smeared.

The 28kHz push-button is a unique feature borrowed from the Avedis E27 equalizer.  It applies a 6dB shelving rise at 28kHz that is very useful for breathing new life and realism into many instruments.
