Chameleon Labs' 581 mic pre puts Neve 1081-style vibe in your 500 series rack! Accommodate any source with selectable impedance and a Hi-Z instrument input.

The Chameleon Labs Model 581 is based on high audio performance design techniques. By employing classic circuit design, polystyrene capacitors, hand selected components and custom wound transformers, Chameleon Labs ensures that the Model 581 will exhibit classic audio sound. It is also designed to comply with any 500 series powered chassis approved by the API(R) VPR Alliance. The Model 581 represents a dramatic breakthrough in delivering vintage audio performance at an affordable price.

The Model 581 microphone preamplifier card has a transformer balanced input with a gain range of +25dB to +80dB. The Model 581 has been carefully constructed and individually tested for quality. It utilizes class 'AB' circuitry. This unit is made with 100% discrete components and was fabricated to precisely match vintage counterparts manufactured in the early 70's.
