The Luxman LV-102 is a pre-main amplifier that premiered in October 1985, priced at ¥ 66,000. It features a sound enhancer that provides unique audio effects by expanding or compressing the dynamic range of music. The amplifier offers two modes—Dynamic AV for expanding the dynamic range and Midnight for compressing it to prevent sound thinning at lower volumes. The CD straight function bypasses part of the signal path to minimize sound quality degradation. It includes two video input systems and a built-in video buffer amplifier for high-quality dubbing. The amplifier employs MOS-FET technology in its driver stage, along with the S.T.A.R. Saiki design principle, which eliminates shared power and ground lines to enhance the signal-to-noise ratio. It is equipped with signal processing jacks for connecting surround processors and graphic equalizers. The LV-102 is specified to deliver an output of 80W per channel at 6 Ω, with a total harmonic distortion factor of 0.007% or less. Other specifications include a frequency response of 20 Hz to 20 kHz ± 0.3 dB for phono inputs, and a wider frequency response of 1 Hz to 120 kHz ± 3 dB for CD, tuner, and line inputs. It has an input sensitivity of 2.5 mV for MM phono and 160 mV for CD, tuner, and Aux inputs. The power consumption is noted at 150W, and the amplifier's dimensions are 438 mm in width, 138 mm in height, and 352 mm in depth, weighing 11.0 kg according to the 1985 catalog.
