Zefiro Inbox Denecke 2-Channel Microphone Preamp

  
The unit is a high quality battery operated microphone preamp coupled with a low noise 20 bit ADC. The SPDIF outputs are optical and coaxial and can drive standard consumer DAT machines or computers that accept digital audio I/O cards, such as the Zefiro ZA-2. The main use for the AD-20 is location recording. The unit is in excellent condition and shows little, if any, wear.

Guaranteed to be fully functional.
