The Sigma 2200i is a powerful stereo integrated amplifier with features like USB and Network streaming, HDMI 2.0 switching and bass management to accommodate the evolving needs of a modern hi-fi system.It leverages the technical and performance advantages of our Sigma series separates to punch seriously aboveits weight class. As an integrated amplifier, the 2200i combines preamp and power amp functions in a single chassis. What’s special is its direct digital connection between the preamp section and the amplifier, which eliminates losses by removing digital-to-analog and analog-to-digital conversions from the signal path.

The preamp section of the 2200i features connectivity and circuit blocks found in the Delta series CP-800 and Sigma SSP. Inputs include fully balanced (XLR) and single-ended (RCA) analog with optional MM/MC phono, digital coax,optical, USB host and device, Ethernet for streaming and IP control and HDMI switching. Techniques like asynchronous synchronization and master clock mode allow us to manage the digital clocks for low jitter and high signal integrity. Analog sources are converted at 24/96 to preserve their original bandwidth and dynamic range.

Unlike outboard DACs and preamp/processors that must output analog signals for volume control and amplification, the 2200i leverages the true digital architecture of our proprietary Classé switching amplifier design, connecting the output of the preamp DSP directly to the DSP input of the amplifier. There aren’t any DACs or ADCs nor is there any unnecessary analog circuitry between. The signal path is as short and direct as possible; signals remain digital all the way to the amplifier output filters.

Power is supplied by Classé’s proprietary switch mode power supply with power factor correction. With over 1,000W available, the 2200i coasts through passages that would bring lesser amplifiers to their knees. In addition to supplying clean, rock-steady voltage to the circuitry, this supply pulls power cleanly and efficiently from the wall. And even if you don’t worry about power consumption, you will benefit from the performance and reliability achieved from the comparatively cool-running circuitry contained in the 2200i’s modestly sized chassis.
A front panel touchscreen and both Android and Apple apps provide sophisticated yet intuitive control. DLNA and AirPlay streaming are supported over the Network connection and AV switching with HDMI 2.0 and HDCP 2.2 allows convenient support of set top boxes, games and disc players. Whatever you want to listen to, you can be sure that the 2200i will stand ready to deploy its arsenal of resources, remain faithful to the music and reliably deliver many years of listening pleasure.
