Inside the Rotel A11 amplifier is typically Rotel. A large, high current toroidal transformer, and the bare minimum of components in order to preserve signal quality.
All signal paths are kept equal in order to reduce any left/right channel timing issues, with left and right channels laid out in a dual-mono fashion.
The digital board for Bluetooth are housed on separate circuit boards to the analogue circuitry to avoid interference.
Bass, treble, and other controls can be adjusted in the menu to your preference, or bypassed altogether. All inputs can be accessed directly from the front panel, as well as speaker selection.
The display also shows volume and input selected, and the front 6.3mm jack allows private headphone listening.
The Rotel A11 provides four analogue inputs, as well as a high quality MM phono stage.
A pair of analogue pre-outputs allow for the addition of a power amplifier or a subwoofer or two.
Two 12v triggers offer auto-power on to suitable equipment, and a second switchable set of speaker outputs can facilitate the addition of either a second pair of speakers or the low level outputs of a REL subwoofer, making it easy to switch them in or out of the system from the front panel of the A11.
