AudioControl’s unique patent-pending AccuBASS™ circuitry in the Rialto 400 rejuvenates the bass response lost in most digital compression schemes and brings it back to the signal path. This results in a richer and fuller audio performance with better bass and mid-bass response often missing in today’s compressed music.
The Rialto 400 has an array of 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 thus making it the most flexible product of its kind. 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.
