Key Features
- Class AB Amplification:
Delivering 50 watts per channel into 8-ohm speakers and 62 watts per channel into 4-ohm loads, the A11 MKII provides the power and dynamic capability required for an engaging stereo listening experience. Its Class AB architecture balances musical detail, dynamic expression and everyday listening versatility.
- Rotel-Designed Toroidal Power Transformer:
At the heart of the amplifier is a substantial toroidal power transformer developed by Rotel. Combined with a linear power supply, it provides stable power delivery to support dynamic musical passages and consistent amplifier performance.
- High-Resolution Digital Audio:
The integrated digital section features a Texas Instruments PCM5102A DAC with a 32-bit/384 kHz capability. Optical and coaxial digital inputs accept compatible PCM audio signals up to 24-bit/192 kHz, making it easy to connect digital music sources and compatible televisions.
- Bluetooth aptX HD:
Stream music wirelessly from compatible smartphones, tablets and computers. Support for aptX HD and AAC provides convenient access to music libraries and streaming services without requiring a physical audio connection.
- Moving-Magnet Phono Stage:
The dedicated MM phono input allows a compatible turntable to connect directly to the amplifier. This integrated phono stage makes the A11 MKII a practical choice for listeners who enjoy both vinyl records and digital music.
- Flexible Analog Connectivity:
Three line-level RCA inputs accommodate a variety of analog audio sources, including CD players, music streamers with analog outputs and other compatible components. The combination of analog, digital and phono connections makes system integration straightforward.
- Dedicated Headphone Amplifier:
A front-panel 3.5 mm headphone output incorporates a dedicated headphone amplifier circuit for private listening. This allows users to enjoy music through compatible wired headphones without switching to a separate headphone amplifier.
- Adjustable Tone and Balance Controls:
Front-panel bass, treble and balance controls allow listeners to tailor the tonal presentation and channel balance to suit their speakers, room and musical preferences.
- Motorized Analog Volume Control:
The motorized analog volume control works with the supplied infrared remote, allowing convenient volume adjustment from the listening position while retaining the tactile feel of a traditional amplifier.
- Compact Hi-Fi Design:
With a width of 430 mm and a height of just 73 mm, the A11 MKII fits neatly into a wide range of Hi-Fi installations. Its clean front-panel layout and black or silver finish complement both traditional and contemporary audio systems.
