About the AudioControl Rialto 600
Feature-packed amp for any space
Feature-packed amp for any space
Powerful, configurable, and compact — the Rialto 600 integrated amp/high performance DAC fits wherever you want great-sounding audio.
AudioControl designed the Rialto 600 amplifier as a flexible solution for multi-room streaming zones. You can connect a Sonos, Bluesound, or other streaming component with digital or analog output to feed robust, musical power to your favorite speakers. This amp has a lot more than that going on under the hood, though — analog and digital inputs, bypassable preamp volume control, subwoofer output, a high-resolution DAC, and more.
This compact integrated amp delivers a clean and tasty 100 watts per channel — or a single channel of 400 watts when bridged. Its small footprint and understated chassis design help it fit into any space. And AudioControl's bulletproof USA-made construction will stand the test of time.
Flexible connections and control
Connect digital audio sources to the Toslink optical or coaxial inputs to make use of the Rialto 600's fine Wolfson DAC, which decodes digital audio at up to 24-bit/192kHz. It also has an analog input that lets you connect, for example, a turntable with a phono preamp, or an external DAC.
The included handheld remote gives you volume and input control, plus AudioControl's accuBASS adjustment for musically boosting lower frequencies. You also get RS-232 and IR remote control options for custom installations. There's even a 3.5mm rear-panel headphone jack.
Tailor your tone
A bank of eight control switches on the back panel let you "set it and forget it." They'll help you balance relative input volume, control built-in low- or high-pass filters, bypass the Rialto 600's volume control — if your connected component has its own — and more.
If you're connecting a powered subwoofer, for example, maybe you want to engage the high-pass filter, so the amp can feed your left and right speakers as much of the Rialto 600's efficient, assertive power as possible.
Configure it for your needs
Use this amp to power a pair of floor-standing or bookshelf speakers and you have a simple solution for great TV and streaming audio in your den, bedroom, or wherever. You could even connect your legacy analog receiver — and all its inputs — driving your speakers with the Rialto 600 but bypassing its volume control.
Connect a powered subwoofer for a more immersive experience. Or break out a really beastly speaker pair, add a second Rialto 600, and operate in bridged mono mode with all the same features, flexibility, and fantastic sound.

Class D integrated amplifier: The AudioControl Rialto 600 is a compact, high-powered Class D amplifier that delivers over 100 watts of power x 2 channels into 8 ohms and 200 watts x 2 channels into 4 ohm loads. It can also act as a mono-block amplifier, delivering 400 watts x 1 channel into 8 ohms.
Wolfson DAC: The AudioControl Rialto 600 integrated amplifier features a built-in, high-performance Wolfson DAC (digital-to-analog converter) that has been specifically designed to provide great performance high sound quality.
AccuBASS Circuitry: Equipped with AudioControl's unique patented AccuBASS circuitry, the Rialto 600 rejuvenates the bass response lost in most digital audio compressed music files. AudioControl's AccuBASS circuit helps recover the bass that goes missing in compressed music files, or when volume is increased and the bass frequencies roll away. The result is a richer and fuller audio performance with better bass and midbass response.
Low Pass & High Pass Crossovers: The Rialto 600 features a built-in Low Pass Crossover for its mono-subwoofer output and a High Pass Crossover for its speaker outputs. The 80Hz high pass crossover filter allows the main speakers to play the range above 80 Hz, while the 80Hz low pass crossover filter sends the frequency range below 80Hz to a connected powered subwoofer. The crossovers help take the strain off your main speakers if they can't reproduce the low frequency range, plus it conserves amplifier power.
Analog Line-Level Inputs: The AudioControl Rialto 600 is equipped with a stereo analog RCA line-level input for connection of an external audio source with analog line-level outputs, such as a CD player, tape-deck, or tuner. There is a High-Gain switch for the analog line-level input which provides an addition 10dB gain to help with analog source that a very low signal output.
Optical & Coaxial Digital Inputs: The Rialto 600 is outfitted with two optical (toslink) and two coaxial (RCA) digital inputs for connection of audio components and devices with a digital audio output such as TVs, satellite/cable boxes, Blu-ray players and game systems. One optical and one coaxial digital input share a digital audio input for a total of two selectable digital inputs (you cannot use all four). The optical and coaxial digital inputs will accept stereo 2ch PCM audio signal (up to 24-bit/192kHz). The digital inputs do not support Dolby Digital, DTS, or other multichannel audio formats.
Binding Post Speaker Output Terminals: The Rialto 600 is outfitted with a set of 5-way binding post speaker output terminals that will accept bare wire (up to 12AWG), pin-connectors, spade-lugs, and banana plugs (single or dual). The binding post terminals are gold-plated for excellent signal transfer and resistance to corrosion. You can connect one pair of 8 ohm or 4 ohm loudspeakers, or you can connect two pair of 8 ohm loudspeakers. In mono-block mode, you can connect a single 8 ohm loudspeaker.
Bridged Mono Out: This mono-RCA line-level output is used to send the right channel output of the Rialto 600 to the analog input of another Rialto 600 amplifier that is also set in Bridged Mono mode and is powering your right speaker. The output is a copy of the right channel of the currently-selected input, and it is affected by the volume level, AccuBASS level, and the 80Hz low pass crossover. The first Rialto 600 amplifier acts as the Main unit where all source connections and volume adjustments are made. The second Rialto 600 amp is the Link unit, and receives the right channel analog line-level signals from the Main unit.
Mono-Subwoofer Output: The AudioControl Rialto 600 amplifier features a mono-RCA subwoofer output for connection of a powered subwoofer. The mono-subwoofer output contains a low-pass crossover filter that can be set to 80Hz @ 18dB per octave or Full-Range.
Headphone Jack: The Rialto 600 offers a rear-panel 1/8" (3.5mm) headphone jack for connection of a set of headphones, so you can privately listen to your music. The headphone jack does not sense the connection of a set of headphones, allowing you to keep your headphones connected at all time. You will need to turn on the headphone output from the remote control. Once the headphone out is activated, the amplifier's speaker outputs and preouts will be muted.
IR Remote Control: The Rialto 600 comes with an IR remote control to provide wireless operation for the the integrated amplifier. Remote control functions include Power On/Off, Input Select (1-2-3), Volume Up/Down, Mute, and AccuBASS On/Off. he Rialto 600 can also learn commands (such as Volume Up/Down and Input Select) from a universal IR remote control. The IR input (3.5mm) and IR output (3.5mm) of the Rialto 600 allow for the amplifier to be installed out of the line-of-sight and to be integrated with a 3rd party control system (sold separately - see Accessories Tab).
RS232 Control: This 3-pin serial connection allows for computer of the amplifier using RS232 communication. AudioControl has created a full set of RS232 codes for use by installers and programmers. The codes are available at AudioControl's website. The 3-pins are configured as Pin1 = RX (RS232 receive), Pin2 = Ground, and Pin3 = TX (R232 transmit).
12V Trigger In: The 12V Trigger input (3.5mm) allows the Rialto 600 to be remotely turned on by a 12 VDC trigger voltage from a connected source with a 12V trigger output. The unit will stay on as long as 12 VDC is applied
Sleep Mode: The Rialto 600 integrated amplifier will automatically go into Standby mode if an audio signal is not detected after approximately 8 minutes. It will come back on when an audio signal is detected.
Protection Circuitry: The Rialto 600 will protect itself if it experiences an unusually large power surge, overheats, or experiences a short in the speaker wires or the speakers. The protection circuit helps prevent damage to the Rialto 600 and speakers. Turning down the volume or turning the unit off will help the unit to cool down and resume normal playback. A flashing red LED on the front of the amp indicates that the unit is operating at its "current limit" and in danger of going into protection.
Detachable AC Power Cord: The Rialto 600 comes with a detachable 68' AC power cord (IEC 2-prong) that will need to be plugged into the back of the integrated amplifier and into an AC power outlet or surge protector (sold separately - see Accessories Tab).
USA Built with 5 Year Warranty: The Rialto 600 is designed, engineered and manufactured in the USA and comes with Audio-control's 5-year warranty.
