FiiO launch a transparent portable cassette player

For truly analog playback, the entirety of the CP13’s audio circuit uses analog devices – from the magnetic tape head all the way to the signal amplification. The result is a classic, unmistakably analog sound.

The CP13’s motor is powered by a high voltage 4.2V power supply, more than the 1.8V or 3V typically found in portable cassette players. This power supply works in tandem with a custom motor speed stabilization circuit, which increases the drag on the motor as necessary to ensure stable movement speeds – which mitigates unwanted pitch changes and also allows the CP13 to be able to handle more cassette tape types.

Unlike the single-ended signal acquisition typically found in current cassette players, the CP13 employs a differential circuit for balanced acquisition of signals from the custom head, ensuring more stable signal transmission, higher signal-to-noise ratio, and lower distortion.
