Aiwa AD-3800U
Little is documented about the Aiwa AD-3800U beyond period test reports. It was featured in the 1983 Stereo Review Tape Recording & Buying Guide (HiFI-Stereo, October 1983, p.1). The record shows a cassette deck, tested by Hirsch-Houck Labs and listed in that guide alongside models from Akai, JVC, Nakamichi, and Sony (HiFI-Stereo, 1983, p.1). The deck covered a frequency range of 31.5 Hz to 18 kHz. The slight bass rise below 100 Hz shown in the graph was not a characteristic of the AD-3800 (HiFI-Stereo, 1983, p.43).
The front panel used long-throw horizontal slider controls for record-level adjustment and a smaller slider for a secondary function. An LED indicator signaled when operation was active (a delay of less than 2 seconds) (HiFI-Stereo, 1983, p.42).
