Pure digital.

With its powerful 32-bit floating-point SHARC Digital Signal Processors equaliser and network control functions, our RS-A9 ODR amplifier features high-performance functions that put you in total control of your sound stage.

An optical digital input allows the amp to connect digitally to the RS-D7R11, preserving the highest quality of the audio signal and forming a pure digital system.

The unit also includes 3 digital outputs so that you can easily combine it with one or more RS-A7 amplifiers to drive your speakers with the utmost sonic purity.

It is suited especially for tweeters and midrange speakers, bringing out the clear and smooth tone of delicate strings.

This amplifier’s design and specialised parts further ensure high-quality sound and a true digital signal.
