This is a stereo digitizer/sampler originally designed by me, featured in the Computer Gazette 4-95 issue.

The current modern implementation has been developed by user wiretap and released as free open project in agreement with myself

WHAT IT IS

Fully compatible with Amiga sampling and editing software, with Stereo Sampling and anti aliasing filters onboard.

Can also work with Retro-PC parallel port hardware !

Jumper J1 allows for switching between PC-DOS and Amiga.

This device works in a wide variety of sampler programs, supporting stereo sound input.

VR1 and VR2 potentiometers allow for gain adjustment for the right and left channels.

For Amiga 1000 support, please use the appropriate parallel port adapter to correct the pinout.

The gain adjustment potentiometers are multi-turn. Once you set your VU levels with no clipping on the audio feed device, adjust the gain potentiometers to an acceptable level, referencing the Amiga tracker/sampler software. Once set, they should not need to be adjusted again, unless switching to another audio feed device.
