Classé Launches 200W Sigma 2200i Classé has launched a new 200W stereo integrated amplifier in its Sigma 2200i series.By RS Staff Published: April 1, 2016 ⋅ Updated: April 15, 2019 By connecting the output of the 2200i’s preamp section DSP directly to the input of the amplifier DSP, Classe eliminates DAC and ADC conversion losses and their associated analog circuitry’s noise and distortion. That’s the key to the new Sigma 2200i stereo integrated amplifier. By keeping digital signals digital all the way to the amplifier output filter, Classé shortens the signal path, avoids losses and eliminates digital-to-analog converters and analog-to-digital converters as well as their associated analog circuits. The front-end consists of the stereo portion of a Sigma SSP, including inputs for USB types A and B, Ethernet for streaming AirPlay and DLNA, coax, optical, analog inputs for XLR and RCA and an optional phono (as in the CP-800 and Sigma SSP). Classé has also included 4 HDMI inputs, adding convenience for users with AV sources like set top boxes, Blu-ray players, etc. The Classé touchscreen control provides familiar features like digital domain tone control, 9-band PEQ per channel and flexible bass management. The subwoofer output is derived from the only DAC onboard. IP control includes Android and iOS apps. The amplifier section consists of the power supply, DSP and amplifier circuitry of an AMP2. It is capable of driving virtually anything on the market including all of the new Bowers & Wilkins 800 Series loudspeakers. The Sigma 2200i uses a 3U tall chassis that occupies the same footprint as all of the other Sigma models. The extra 1U space on the lower third of the faceplate contains an air intake. A small Noctua fan mounted to the rear panel spins quietly at low rpm to gently draw air through the chassis, keeping the circuitry at a comfortable operating temperature while extending the life of the electronic components. The rack-mount solution introduced in the original Sigma series models, contained in the design of the side panels, is retained in the Sigma 2200i. Simply remove the sides, rotate and flip them, then reattach to position rack ears for rack-mounting. The US retail price for the Sigma 2200i is $5,500 and will be available May 2016.
