Traverse Analogue 652

Traverse Analogue 652 stereo vacuum tube preamplifier with mic/line-level inputs

Using the GAIN control, the engineer can achieve 5 - 60 dB of gain from the uniquely-biased tube input stage, followed by a MASTER attenuation control in the output buffer stage. Want a clean yet musical replication of the source? How about the creamy saturation of an esoteric vintage preamplifier?

The 652's gentle drive characteristics allows for a broad tonal palette depending on how hard you hit it with signal. It is designed to interface with all types of microphones (including ribbons), and the line-level input pad allows you to add analogue warmth to any track from a digital audio workstation; making it an indispensable tool for adding colouration and harmonic distortion!

Two flavours, one box, all discrete, and proudly hand-crafted in Canada.
