Used but works well! No issues.
Price dropped and best offer now accepted. This lists new for £300 in the UK.
Selling now for £115 + cost of shipping to wherever you are in the world.
Will entertain best offers here as well (by PM), but Paypal a must.
Here is the info on it:
The AD-20 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. Most low cost DAT machines have noisy front ends and a good preamp with a higher bit converter can improve the signal to noise by up to 15dB.
