ROTEL RA-931 MK II Stereo Integrated Amplifier / RT-940AX AM/FM Stereo Tuner Combo
The RA-931 MK II from ROTEL is an integrated stereo amplifier engineered for superior performance. Its symmetrical circuit paths are applied to guarantee identical accuracy between channels. A custom ROTEL-made toroidal power transformer fuels the device, together with premium capacitors to raise the speed and damping factor of the amplifier. To enhance the sound, a carefully regulated power supply is employed in all our products. The Bass and Treble tone controls serve to boost the low bass or the high treble components of the audio, while avoiding distortion of the essential middle frequencies (vocal range). They are also switchable, permitting users to enable or disable them.
