Kenwood DPX-05MD

The Kenwood DPX-05MD is a double-DIN receiver with CD and MiniDisc transports and an FM/AM tuner. It is documented alongside the DPX-04 and the DPX-05MDB in publication B64-2859-00, with a separate specification page for each. The DPX-05MDB is the same unit in a different finish and shares this specification page.

Both transports use a GaAlAs laser diode with an eight times oversampling digital filter and a 1-bit digital-to-analogue converter. The CD mechanism runs at 500 -> 200 rpm under constant linear velocity, the MiniDisc mechanism at 450 -> 950 rpm. Wow and flutter on both is quoted as below measurable limits.

The CD section is specified at 100 dB signal-to-noise at 1 kHz, 7 dB higher than the CD transport in the cassette-equipped DPX-04 documented in the same manual, though both are quoted at the same 0.01 percent distortion and 93 dB dynamic range. The MiniDisc section returns 90 dB signal-to-noise and 90 dB dynamic range.

Output is rated at 30W x 4 into 4 ohms at 1 kHz and 10 percent THD, with a maximum of 50W x 4. Unlike the DPX-04 page, this specification lists a pre-out, at 1.8V into 10 kohm with an output impedance of 600 ohm or less. The supplied parts list covers the power harness and mounting hardware only, with no remote control.
