Harman Kardon HD7500II CD Player

Here we have a vintage compact disc player from Harman Kardon. The HD7500II is in fully working condition noting a few marks to the casework and will be supplied suitably packaged along with our regular three month warranty.
Harman Kardon Said….
Compact disc players vary in their techniques for bringing out the musical information from compact discs. Harman Kardon Bit Stream compact disc players use their own method: Pulse Width Modulation. Here the incoming audio signal is sampled 10 times faster – 10 times more often – than with conventional technologies. The result is truer reproduction of the original waveform, creating more musical detail and less noise. In fact, the noise is relegated to frequencies so far above the audio bandwidth that it can be removed. Sound that might otherwise be grating or metallic is substituted with more natural sounding music.
Sound signals travel through analogue circuitry before arriving at the compact disc player’s output jacks. Those stages may employ mass produced integrated circuits or custom designed discrete circuits. Harman Kardon uses only discrete circuits along the audio path, insuring that the best possible sound produced by the sampling and conversion systems is achieved. Discrete circuits embody close tolerance resistors, capacitors, and fast slew rate transistors. The benefit is wider bandwidth and minimal negative feedback, both of which are critical to the compact disc player’s amplifier stages.
