Exposure XXII
The Exposure XXII is an integrated amplifier from Exposure Electronics. What survives on it is mostly specification sheets, not deep documentation. No production years, original pricing or design details have surfaced in the research, so a full history isn't possible yet. The electrical and physical specs are known with reasonable confidence, since they appear consistently across several period database entries.
The amplifier was rated at 60W per channel into 8 ohms. One source lists 70W at 8Ω, but the 60W figure is the more commonly repeated one. Total harmonic distortion was stated at 0.02% at rated output. Frequency response was specified as 20Hz to 20kHz ±0.25dB, input sensitivity at 150mV, and signal-to-noise ratio at 80dB. It had five line inputs plus a tape monitor. It measured approximately 440 x 87 x 320mm (or 43 x 8 x 32.5cm, depending on the source) and weighed 10.2 kg.
The magazine record is thin. The only indexed mention is in Audio-Collection, and that piece is about general loudspeaker longevity, not a review of the XXII. Period critical reception for this model appears not to have been documented. The article advises that reasonable protection from damp, dirt, and metal filings is essential for longevity (Audio-Collection, p.73). The XXII sits alongside Exposure's other roman-numeral models (IV, XIII, XIV, XV) in the archive, but no explicit family relationship has been confirmed in the sources.
