The Kenwood DP-770 D is a compact CD player that was manufactured from 1987 to 1989 in Japan. It features a three-beam high-precision low-noise optical pickup, enhancing its playback quality. The device employs a self-pulse-modulated oscillation laser, which reduces operating noise and enhances audio performance. The optical system is designed with an objective lens that has a wave aberration of λ / 40, thereby improving precision and efficiency. A notable design aspect is the floating signal reader, which is insulated to prevent interference from external vibrations. Audio processing benefits from high-performance LSIs across its servo systems, digital processing, and D/A converter circuits, which also enhance reliability by minimizing component count. The DP-770 D utilizes a unique power transformer to balance sound quality and a compact form factor. It features a soft-touch loading mechanism for ease of use, alongside direct search and memory functions for efficient track navigation. The front display is a focused large FL tube, enhancing visibility. With a dynamic range of 93 dB, it supports 44.1 kHz sampling at 16-bit linear quantization, and presents a frequency response of 4 Hz to 20 kHz (± 0.5 dB). The device’s dimensions are 340 mm in width, 74 mm in height, and 351 mm in depth, weighing 5.8 kg. Output specifications include a 2 V (0 dB) terminal output and a headphone output of 32 mW at 32 Ω.
