Description stereo amplifier, Rotel RA-11 V2

Integrated amplifier Rotel RA-11 V2 differs from the normal model RA-11 availability RS-232 interface, which allows you to control all its functions with the help of complex computer systems, and also serves to update the firmware.

Model RA-11 V2 has a built-in Wolfson WM8740 DAC (24bit/192kHz) and new control processor. Used carefully selected high-quality components, including metal film resistors and other elements. In the power supply traditionally used a toroidal transformer with low output impedance. Power is 40 watts per channel at a load of 8 Ohms.

Amplifier received all-metal case made in a slim design. In the center of the front panel mounted 2-line LCD display showing the selected input, volume, menu, etc. Under it are 8 buttons input selector. On the right there are navigation buttons for menu and volume knob. To the left of the display is set the selector of the connected sets of speakers. On the left of the façade there is a power button/standby with LED diode, operation indicator protection and USB port for external storage. The USB input is compatible with iPod/iPhone/iPad. It is also possible to connect an external Bluetooth adapter for wireless audio transfer from mobile devices. For headphones on the front panel has a 3.5 mm output.

Rotel RA-11 V2 has a well-developed switching. Inputs: four RCA line, MM connectors-Phono stage for vinyl player, 2 coaxial and an optical connector. There is a cascade preamplifier output Pre Out (RCA). There is a socket on the system bus (this connector the entire system can be controlled from a smartphone or tablet app via the Rotel Remote App), a pair of trigger outputs and RS-232. For connecting speaker systems are 4 pairs of screw terminals. Amplifier equipped with a remote control. Balance adjustment and tone (HF and LF) can be done with the remote or through the menu with the front panel. For more natural sound linear you can activate the bypass mode of adjustment of a timbre.

The amp is consistent with the current requirements, providing not only analog, but with digital sources. Sound Rotel RA-11 V2 is characterized by accuracy, excellent detail, good dynamics and rhythm.
