Do you remember?
In 1982, Henry Engineering began manufacturing and delivering its first product: the Matchbox. This utility device proved to be a popular interface for balanced and unbalanced audio signals. In its original form, the unit delivered an audio response of dc to 20kHz ±0.25dB at 0.008 percent distortion with a S/N ratio of about 80dB.
After 25 years, Henry Engineering offers an updated version that fits in a 1/3-width, 1RU package. The current unit places the audio connections on the rear panel, unlike the original that provided all the connections on the front of the project box.
Henry Engineering reports that the Matchbox will be available in the original configuration in the coming weeks — just in time for its silver anniversary.
