This means you get the detail, great bass, and overall efficiency of a class-D amp with the smoothness and natural reproduction of a class A or AB amp.\u003c\/p\u003e\n\u003cp\u003eAn optional tone control allows for +\/- 15 dB adjustment of bass and treble, and uses active EQ to preserve fideilty.\u003c\/p\u003e\n\u003cp\u003eThe RA180 uses a dual-mono design powered by a high-efficiency supply that uses silicon carbide FETs to allow for high output with minimal heat generation. Also, the RA180 has a 2.5 kW power factor correction circuit that allows for excellent transient response. \u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ch1\u003e\n\u003c\/h1\u003e\u003cp\u003e\u003cstrong\u003ePower Output (4 Ohm \u0026amp; 8 Ohm):\u003c\/strong\u003e 250 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e 1 x stereo RCA phono MM, 3 x stereo RCA line, 1 x stereo XLR\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1 x stereo speaker, 1 x RCA subwoofer\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WDH):\u003c\/strong\u003e 17\" x 14\" x 4\" (430 x 355 x 103 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 21 lb.
