Trident Audio Developments A-Range 500 Fourd Band Equalizer Module

The legendary A-Range equalizer holds a unique place in audio history, with a stunningly musical sound that resulted from its all-discrete transistor circuitry and the use of inductors in the upper and lower mid bands. The A-Range is a faithful re-creation of the original four band Trident A-Range equalizer in a 500 module format, that will add the unique Trident signature to any programme material.
