The AudioControl Rialto 400 is a compact amplifier with a built-in digital to audio converter (DAC) providing both analog and digital systems (including Sonos systems) with greater performance and higher sound quality.
It delivers 100W per channel into 8ohms and 200W per channel into 4ohm loads. A Wolfson DAC improves audio quality, allowing digital and analog audio systems to perform with better speakers across the home.
The company claims the amp has AccuBASS circuitry to add bass response lost in most digital compression schemes, and "brings it back to the signal path."
Inputs include PCM to connect to with digital audio ouputs from TVs, a 12V trigger for use with control and automation systems, toslink, coax, line level RCA, 1/8" audio and speaker level inputs for interfacing with source units without line level. An integrated headphone jack use with gaming systems or personal audio products such as headphones.
