Your Model 7622 microphone dual preamplifier has a
transformer balanced input with a range between 20dB
and 80 dB of gain. The separate line input is transformer
balanced and accepts input levels from -20 to +10dB.

The Model 7622 has been carefully constructed and
individually tested for quality. It utilizes pure class ‘A’
circuitry. This unit is made with 100% discrete
components, hand wound transformers and was fabricated
to precisely match vintage counterparts manufactured in
the early to mid 70’s.

The Chameleon Labs Model 7622 is based on high audio
performance design techniques. By employing classic
circuit design, polystyrene capacitors, a gold contact gain
selector and custom wound transformers Chameleon Labs
ensures that the Model 7622 will exhibit classic audio
sound.

Your Model 7622 represents a dramatic breakthrough in
delivering vintage audio performance at an affordable
price.
