REFURBISHED - AKG D11/H1/A MID 1950 - XLR

Produced in Western Germany in the 1950s and 60s.

The AKG D 11 HI A was developed for speech, broadcasting, and public address, offering a straightforward transformer-based output without the added complexity of switchable filters found in some of its siblings. This results in a direct, honest signal path and a very characteristic vintage tone.

Refurbished and fully tested. Inner foam replaced and properly remounted. Fully functional.
