Designed for professionals, this A/D/A converter substantially improves computer availability
This general-purpose A/D/A converter combines an analog-to-digital converter with a digital-to-analog converter in a compact package. Unlike conventional on-board A/D and D/A converters with their handling difficulties, the ADA-200R has both A/D and D/A conversion functions, as well as all other required functions in a beautiful, sturdy case.
This cost-effective unit is probably the very best, the one that professionals have long waited for. The ADA-200R is capable of controlling input and output signals between a computer and a variety of analog devices including electronic musical instruments, audio equipment, and measuring instruments for such major applications as wave memory, data preparation from sound waveform analysis/synthesis/recognition, synthesizer and laser control, joy stick, paddle, and waveform generator. Thus, computer versatility is substantially improved.
Every required function in a compact package
The ADA-200R consists of an input pre-amp, input filter, sample and hold circuits, output filter, over-level detector circuit, trigger detector circuit, I/O address decoder, power supply unit, and A/D-D/A converters
It is provided with two connectors for optional printed circuit boards, one of them is a 2-channel expansion unit (OP-1) that facilitates signal comparison.
