The AudioControl Rialto 400 is a compact, high-powered amplifier with a built-in audiophile-grade DAC (digital to analog converter) designed specifically to provide greater performance and higher sound quality for all analog and digital systems, including Sonos home entertainment systems.

The Rialto 400’s amplifier delivers over 100 watts of power per channel into 8 ohms and 200 watts per channel into 4 ohm loads. Features a built-in high-performance Wolfson DAC that drastically improves audio quality, digital and analog audio-systems can perform with better speakers across the home. AudioControl says its patent-pending AccuBASS circuitry in the Rialto 400 adds bass response lost in most digital compression schemes and brings it back to the signal path. The company says this results in a richer and fuller audio performance with better bass and mid-bass response often missing in today’s compressed music. Hmm, bringing something back after it’s gone? Not sure about that claim?!?

The Rialto 400 has both digital and analog inputs, including PCM to connect with digital audio outputs from televisions and a 12V trigger for use with control and automation systems. Toslink, coaxial, line level RCA, 1/8″ audio and speaker level inputs for interfacing with source units without line level are included in the specification. This plethora of inputs eliminates the need for additional expensive outboard components. The Rialto 400 also features an integrated headphone jack to allow it to be used in other applications such as gaming systems or with personal audio products such as headphones.

Here are all the specs.
