• Full I/P control
• Total harmonic distortion + noise = 0.003%

There are two frequent problems with hi-fi amplifiers. Class A, the traditional audiophile’s choice, uses a single power supply constantly running at full capacity, even when there’s no signal coming through. Great for reproducing those subtle details at low levels however struggles to provide extreme power when needed.

Class A/B, the most common amp class, switches between the two internal amplifiers, one for each half of the waveform. Far more efficient but often a recipe for crossover distortion, since those low-level details we crave can get lost within any mis-match between the two switching over.

Class G is essentially a hybrid amplifier, utilising Class A specifically for low-level signals, but when required switching in an additional power supply to power those larger sections of the waveform.

Powerful Amplifier 7-Channel Discrete Reinforcement Layout with Eco Mode
With maximum power channels of 200 watts each, the AVR-X4100W final design features support multiple high-current output devices with identical circuit topology for all seven channels. Our new Eco Mode allows reducing the overall energy consumption and has Eco Meter on the screen, allowing you to see graphically the reduction of energy consumption. The Auto Eco mode automatically switches between normal energy consumption and Eco modes, depending on the selected volume level. The final portion of aid may lead loads low-impedance until the 4 ohms, for compatibility and stability with almost any speaker model.

Audyssey MultEQ-XT32 / LFC
It is the most accurate room correction solution with more than ten thousand individual control points, allowing to identify the smallest details of the room problems and corrected. The ultra high resolution filters are applied to all channels, including two independent subwoofers, with the obvious advantage of sound in low frequency range, where most demand is the correction. The Audyssey LFC uses psychoacoustics algorithms to prevent the bass so you do not spend your walls and disturbing your neighbors, while keeping the bass performance in listening room. The AVR-X4100W is also prepared for Audyssey Pro for the more advanced professional room correction.

Multiroom / Multisource
The AVR-X4100W lets you enjoy program source in the Main Zone (the room where is placed the AVR-X4100W) and Zone 2 and Zone 3. The source may be the same for all zones or you can enjoy different sources in these areas, if desired. The sources for the zones can be either analog or digital 2 channel PCM sources (including optical, coaxial, HDMI and network).
