Typical front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape eject is operated mechanically and the cassette needs to be placed with the side to be played facing forward in the cassette well.

Level meters used on the AD-300 are generic digital peak reading meters. Full-logic transport controls used on the AD-300 let it respond to the slightest finger contact for fast and effortless transport function selection.

Dolby C-type used in the AD-300 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. To further maintain recording accuracy, the AD-300 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the AD-300 can be swiched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.

For undisturbed listening a jack connector for a pair of stereo headphones is supplied.
