NV73

DIY 1073 Class A

Built/provided by The DON Classics

0dB line setting to warm up your digital recordings while mixing

Output attenuator allows more sound options

Impedance switch lets you choose 300 ohms for your old ribbon mics

DC-DC converter to change the +-16V(32V total) to 24V so the module just sees a clean single 24V rail.

Slow start circuit, meaning the module never uses more than the 130mA allowed. Even inrush current stays below 130mA.
