AudioControl Rialto 400 Solves Amplification & Digital Audio Dilemma

With a choice of digital inputs that includes Toslink, digital coax, line-level RCA, 1/8-inch and speaker level, as well as other installer-friendly features such as 12-volt triggers, electronics professionals can integrate AudioControl's Rialto 400 amplifier/DAC into a variety of A/V systems without losing functionality.


AudioControl says the Rialto 400 is available in a choice of white or black, and it carries an MSRP of $799.

The Wash.-based audio company AudioControl manufactures products for the pro audio and consumer audio markets, and within its line of consumer audio components are a variety of components that target home theater installations.

Now that it has started to ship its Rialto 400 amplifier/digital-to-analog (DAC) AudioControl’s dealers can address the growing two-channel market that includes the surging digital audio category. The Rialto 400 is a compact solution that measures 8.5 inches wide by 2.9 inches tall and 5.4 inches deep, and AudioControl has designed its two-channel to deliver 100 watts into an 8-ohm load and 200-watts into a 4-ohm load. In addition, the company says that installers can configure the unit to operate in a bridged, monoblock mode.

What makes the Rialto a different product within the market is its inclusion of a digital-to-analog conversion (DAC) section that allows electronics professionals to connect digital audio devices that range from Apple iOS and Android products, to streaming wireless products like the Sonos product line to the product to serve as an all-in-one amplifier/DAC solution. “The Rialto 400 is truly unique with its impressive size and quality of performance,” states Alex Camara, CEO of AudioControl.

“While digital audio systems have gained tremendous popularity they still tend to be under-powered and are unable to deliver high-quality performance ... until now. The Rialto 400 is a compact, audiophile-quality solution that combines the convenience of digital systems, our high-power amplification and world-class DAC technology to create incredible audio performance.”

Internally the Rialto 400’s DAC section employs Wolfson’s digital-to-analog (DAC) chips to provide state-of-the-art processing, and the Rialto 400 also includes AudioControl’s AccuBASS circuitry that is said to restore the bass content that is lost in most digital compression schemes. The combination amplification/DAC Rialto 400 also offers a full selection of inputs that include Toslink and digital coax, and analog options such as line-level RCA, 1/8-inch audio and speaker level. Installer-friendly options include 12-volt triggers and the company’s SMART Signal Sensing technology which can be set up to prioritize specific inputs.
