Integrated amplification, loudspeaker control and sources in a single chassis
Rotel A-11 MKII is a Class AB integrated amplifier rated at 50 W per channel into 8 ohms and 62 W per channel into 4 ohms, designed to combine preamplification and power amplification in a complete stereo chain.
The output section is powered by an in-house high-current toroidal transformer and operates through a direct analogue signal path. A 32-bit/384 kHz Texas Instruments DAC handles digital sources, while three RCA analogue inputs ensure compatibility with traditional components. The front panel includes a dedicated headphone output, while motorised volume, tone and balance can also be controlled from the remote.

Power and control
A-11 MKII delivers 50 W per channel into 8 ohms and 62 W per channel into 4 ohms, with declared THD below 0.03%. A damping factor of 120 complements its current capability and helps maintain woofer control, particularly as loudspeaker load varies with frequency.
Power supply
An in-house high-current toroidal transformer powers the amplifier. The transformer and filter capacity support the output section during transients and keep the supply voltage stable, so dynamic performance does not rely solely on the declared nominal power.
Conversion and digital inputs
A 32-bit/384 kHz Texas Instruments DAC is joined by coaxial and optical inputs. Digital sources can therefore connect directly to the integrated amplifier and use its internal conversion, reducing the number of separate components in the chain.
Analogue inputs
Three RCA analogue inputs are provided. Line-level sources enter the preamplifier without conversion and share the same volume control, allowing a system to be built around players, tuners, external DACs and other analogue components.
Vinyl
An MM phono stage is included. A compatible turntable can therefore be connected directly without adding an external phono preamplifier, keeping vinyl within the same control system.
Connectivity and everyday use
Bluetooth supports aptX™ HD and AAC. The front panel includes a dedicated headphone output, while motorised volume, tone and balance can also be controlled from the remote. These functions complement the wired sources and adapt the amplifier to a modern system without altering the analogue path when they are not required.
Chassis and dimensions
The chassis measures 430 x 73 x 347 mm and weighs 6.8 kg. Transformer, heatsinks and circuit boards are arranged to keep sensitive sections away from the main sources of noise and heat, providing a stable mechanical base for the power section.
