    ACI 600 - Asynchronous Control Integrated

    aci 600 flat angle

    The ACI 600’s advanced integrated platform expands the way you live with your audio. The ACI 600 suite of options focuses on the core technologies of our high dynamic range DAC, precision volume and system control, Ethernet Streaming, phono stage and headphone technologies, powered by ultra-low noise amplification for the ultimate in high performance integration.

    The ACI 600 is designed to manage the complexity of all audio source and control functions with ease and efficiency. The volume and system functions are controlled by manually pressing and rotating the control dial on the top of the unit, or by using the IR custom remote control, or with your iPhone/iPad and the custom iOS app. The fully programmable display is easy to read and illuminates system status indicating source and volume. It also displays all programming functions and serves as the streaming display for meta data.

    All source inputs are asynchronously re-clocked into the fully balanced advanced segment DAC measuring below 0.0005% distortion and 127dB of dynamic range. By stripping away the source clock and using Bel Canto’s custom ULN master clock circuitry we significantly reduces both jitter and distortion preserving the delicate audio signals from all sources.

    Asynchronous ethernet streaming connects you to the most compelling musical source control environment and streaming audio experience with the highest sonic performance. Bel Canto’s proprietary asynchronous ethernet supports high resolution files up to 24bits at 384KS/s and DSD256 in a NAS (networked attached storage) environment or subscription streaming service, delivering the most accurate and detailed signal transfer making it the highest performance digital source option.

    Asynchronous Digital AES, RCA and TOS link inputs all operate at 24/192Ks.

    Asynchronous USB2.0 Audio is compatible with any PCM source up to 24/348 and DSD 256. Windows-based computers require our custom driver. USB2.0 works natively in OSX.

    RS232 is designed to support easy integration with sophisticated whole house control systems.

    The MM/MC phono section is a low noise, low distortion circuit that is fully programmable for optimum application with wide range of quality cartridges from high output MM 2.5mV to 5mV to low output MC 0.25mV to 0.5mV to optimized performance.

    The line level analog input also can be programmed to gain match your analog sources and achieve the best performance from all analog sources. The line output can be connected to a powered subwoofer.

    The rear mounted headphone jack opens up high quality sound for your favorite headphones. Plug in your headphones and the ACI600 configures itself into a superb headphone amplifier with a high performance buffer stage that can drive down to 32 ohm. Control the output level using the main control, allowing you to select the headphone or main speaker output while leaving the headphones in place.

    digital output slice

    The ACI 600 uses a unique ST glass fiber StreamLink digital output to allow you to expand your integrated into monoblock’s using the MSP1 unique power and performance. This high-speed, no-loss, no-noise signal transfer is non-interactive and completely eliminates ground loops and noise artifacts that can occur in cables. This provides maximum flexibility for component placement. Whether the cable is 1 meter or 1000 meters, there is no signal degradation.

    speaker output slice

    The ACI 600 has WBT vibration isolated NextGen speaker connectors delivering the purest audio signal to the speaker. The fully insulated design is made from a hybrid of functional materials. The tightening nut acts as a vibration damper against impact sound as well as a pressure indicator. Made from pure fine silver each post accepts 4mm2 bananas and ¼ inch spades.
