Exposure 18 (1980s)
The Exposure 18 is one of the great British integrated amplifiers of the 1980s. It's a no-nonsense, straight-wire-with-gain design from Exposure Electronics that succeeded the Exposure VII and sat above it in the lineup. It's solid-state, built around a classic complementary feedback circuit, with a large toroidal transformer in the power supply. It's rated at 70 watts per channel into 8 ohms, with a signal-to-noise ratio of 90 dB and THD of 0.03%. It has five line inputs, two tape outputs, and a preamp output. It measures 440 × 350 × 90 mm and weighs 9 kg.
The 18 has a distinctly British sound. It's punchy and dynamic with a lovely midrange, a little lean in the bass, but very open and transparent. It's a very musical amplifier, and some owners prefer it to far more expensive modern designs. It can come across as a bit bright with modern speakers, so partnering matters. Audio (December 1985, p.126) carried dealer listings for Audio Exposure gear during this period, confirming the brand's active presence in the US market.
On the second-hand market, the 18 stays popular, with prices from roughly £500 to £900 depending on condition. Two common problems: the capacitors dry out over time, and the original power switch tends to fail. Replace it with a quality aftermarket part. The model is sometimes called the "Exposure XVIII," which may indicate a different version of the amplifier.
