Description stereo amplifier, Rotel RA-12 V2
Model RA-12 is the highest in a new series of integrated amplifiers Rotel and the company is able to provide a power of 60 watts at load 8 Ohms.
Rotel RA-12 was designed, which is fundamentally different from the appearance of the components of the previous rulers. The center of the facade is a two-line LCD display that indicates which source was selected, as well as showing the volume level and set the value tone bass and treble. Available brightness adjustment and contrast. Below are eight buttons input selector. The left side is the power button in the network indicators for power and protection, selection knob acoustic couples, mini-Jack for headphone and USB port, compatible with iPod, iPhone, MP3 player, flash drive or Bluetooth adapter. Balance settings and voices is possible only from the menu system. Menu buttons, navigation, and setting the required values are in the right part. Next is handle the volume control. The remote control can command the CD player and tuner.
The key difference amplifier Rotel RA-12 from previous models is the presence on Board of the Wolfson WM8740 DAC. Special attention the engineers paid to design printed circuit boards, providing a full symmetry of both channels. The element base includes polypropylene capacitors, metal film resistors and other carefully selected components. The power supply uses two high-capacity capacitors and a toroidal transformer with good power supply and low output impedance. Tones the amplifier is disabled by default to ensure the shortest signal path. If necessary, they can be activated.
Inputs: four line RCA connectors on the Phono stage for MM cartridges, two coaxial, two optical. There is direct access from the preamplifier stage. There is a trigger output jacks and a 3.5 mm socket to connect the RA-12 digital gateway Rotel RT-12, thanks to which you can control the amplifier using proprietary software application installed on your iPhone or iPad. There is a Mini USB port for upgrade SOFTWARE. Provides for the connection of two pairs acoustic with eight screw terminals.
The sound of Rotel RA-12 rhythmic, energetic and moderately detailed. Well defined bass, but mid is a superb solution. Given the presence of DAC, wide connection options and excellent performance, the amplifier will become quite a good buy in this price segment.
