Description :
Utilizing the technology development for its predecessor, the top-rated DP-80L/DC-81L, the Accuphase DP-60, brings to the user an attractive world of music, unattainable with any other CD players of this class. The side panels of the DP-60 use natural persimmon board, with only the necessary switches on the front panel for ease of operation. Despite this simplicity of appearance, the DP-60 has many convenient functions, such as "power-on" play that automatically starts playback when the power is turned on, and a function to display and play back units of one frame (1/75 second). Inside the chassis of the Accuphase DP-60, digital circuitry, such as the player, is electrically isolated from the analog circuitry by ultra high-speed, optoisolators with a transmission capacity of 40Mbits/second. In addition, special technology protects the internal circuitry from electromagnetic and static electricity interference, thus preventing the sound quality from being degraded by high-frequency noise.
Carefully selected, top-grade 18-bit ICs are adopted for the D/A converters, each of which is precisely adjusted on the production line to achieve upper-limit performance. A 20-bit eight-time oversampling filter is provided for the left and the right channels. These digital filters are independent of each other and achieve bandpass attenuation of -110dB and a bandpass ripple of +/- 0.00005dB. The Accuphase DP-60 can boast a lot more of Accuphase's state-of-the-art technology though, such as a noise shaper that reduces re-quantized noise to near theoretical lower limit, a 3-pole GIC lowpass filter with excellent amplitude and phase characteristics, a high-precision digital deemphasis circuit with a deviation of +/- 0.001dB, and digital remote control that can adjust the gain up to -24dB in 1dB units. The custom-built 8-bit microprocessor in the DP-60 gives remarkably short access time of 1 second or less. Another feature of Accuphase DP-60 is its rigid construction and high resistance to vibration and shock. The linear motor laser pickup is securely mounted on a diecast aluminum frame and the mechanism itself is fixed to a metal chassis of 1.6mm thick, so that the vibration generated by the motor is almost completely absorbed.
