The 993's output stage uses a small and agile output FET to serve this region, giving superior performance where it has most impact. When current demand rises, higher power bipolar devices supply additional current to move the loudspeaker with up to 125 watts into 8 Ohms.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe amplifier has zero global negative feedback, but because of high bias it still exhibits a low output impedance. TAS link connectivity provides functions such as remote switch on, remote status monitoring through the system controller, and security bonding The 993 is unconventional only because every element of its design and construction has been driven by a passion to deliver performance that will captivate and delight the listener.\u003c\/p\u003e\n\u003c!-- split --\u003e\n\u003cp class=\"\"\u003e \u003c\/p\u003e\n\u003ctable style=\"width: 227.06%;\" height=\"2032\" border=\"0\" cellpadding=\"5\" cellspacing=\"100\"\u003e\n\u003ctbody\u003e\n\u003ctr align=\"center\" bgcolor=\"#333333\"\u003e\n\u003ctd style=\"width: 83.3344%;\" colspan=\"2\"\u003e\n\u003cdiv\u003e\u003cspan style=\"color: #ffffff;\"\u003eSpecifications\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Size\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 465*346*106 (W*D*H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Size including connectors\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 465*378*106 (W*D*H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Packaged Size\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 590*510*250 (W*D*H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Weight\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 19 Kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Packaged Weight\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 22 Kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Standby Power Consumption\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e \u0026lt; 1 Watt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Idle Power consumption\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 50 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Maximum Power consumption\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 700 Watts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Inputs\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 1 pair RCA phono sockets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Input impedance\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 400K Ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Input sensitivity\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 2.0V RMS for Rated output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Rated Power (8 Ohms)\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 125 Watts per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Rated Power (4 Ohms)\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 200 Watts per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Recommended load impedance\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 4-16 Ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Frequency response\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e 5Hz-30KHz +\/- 0.5dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Distortion\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e Less than 1% A weighted at rated output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 45.5006%;\"\u003e Phase\u003c\/td\u003e\n\u003ctd style=\"width: 37.8338%;\"\u003e Phase correct (non inverting)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e"}
