Akai AX-10 Automatic Dynamic Range Expansion System

The Akai AX-10 is a noise reduction system with Adres noise reduction, it was introduced by Akai in 1979.

The features of the AX-10 include.

To ensure the best response from the wide variety of tapes available adjustment of, sensitivity, to optimum levels can be performed prior to recording.

The Toshiba Adres noise reduction system used in the Akai AX-10 expands the tape playback dynamic-range greatly right across the frequency range reaching an incredible 100dB at 1kHz. Signal-to-noise ratio is improved dramatically: by 30dB at 10kHz eliminating all tape hiss, and 17dB at 100Hz. To further maintain recording accuracy, the AX-10 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the AX-10 can be swiched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.
