At CES 2013 next week, AudioControl will introduce a compact digital stereo amplifier with built-in Wolfson digital-to-analog converter (DAC). The company says the new Rialto 400 is designed to provide better sound quality from all digital and analog sources, citing Sonos' wireless music distribution system as a typical application.
Rated at 2x100 watts into 8Ω and 2x200 watts into 4Ω, the Rialto 400 has coaxial and optical digital inputs, as well as line-level RCA and 3.5mm inputs, plus speaker-level inputs. Its SMART Signal Sensing feature allows users to prioritize inputs, so that when the amplifier is turned on, it will search for the preferred active signal. The Rialto 400 also has a 12V trigger for use with control and automation systems.
According to AudioControl, the Rialto 400's AccuBASS feature restores bass response lost in most digital compression schemes, improving sound quality from services like Pandora and Spotify.
The Rialto 400 will begin shipping in February, with a suggested client price of US$799. AudioControl products are distributed in Canada by Evolution Home Entertainment Corp.
