Exposure IV Stereo
Documentation on the Exposure IV Stereo is thin, and even its place in the Exposure lineup takes some untangling. The record shows it was a 50W-per-channel power amplifier - a separate, line-level unit with a single input and a single output, built to be paired with a preamp. The IVS, listed separately in period equipment directories, appears to be that companion preamplifier. The exact relationship between the two isn't spelled out in any source on file.
The design is simple. The IV Stereo had two identical chassis sharing a single cabinet, which gives a monoblock look without the separate boxes. The whole circuit was described as very simple. Protection relays were fitted. It was a slim unit: 432 x 61 x 250 mm and just 6 kg, with a pair of speaker terminals that could drive one pair of speakers. Audio (December 1987, p.57) listed Exposure among the finest home audio component manufacturers of the period, though the reference is a dealer directory rather than a review of this specific model.
Beyond that, the record goes quiet. There are no production years, no original price, no frequency response or distortion figures, and no owner impressions. If you have one of these, or paperwork for it, the archive would like to hear from you.
