During the development of the K-300i Integrated Amplifier we discovered substantial sonic improvements by lowering the output impedance below traditional norms. So we applied this technique to our existing line of amplifiers and the improvement was sosubstantial that it required a unique designation, hence, “XD.”\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:-\u003cbr\u003ev \n\nFrequency response:\u003cbr\u003e\n 20 Hz to 20 kHz +0, –0.13 dB\u003cbr\u003e\n \u0026lt; 0.5 Hz to 100 kHz +0, –3 dB \u003cbr\u003e\u003cbr\u003e\n\nSignal-to-noise ratio:\u003cbr\u003e\n \u0026gt; 98 dB, wideband, unweighted, referred to full power output\u003cbr\u003e\n \u0026gt; 116 dB, “A”-weighted\u003cbr\u003e\u003cbr\u003e\n\nGain: 26.2 dB\u003cbr\u003e\u003cbr\u003e\n\nTotal harmonic distortion:\u003cbr\u003e\n \u0026lt; 0.045% at 1 kHz, at 300 W, 8 Ω \u003cbr\u003e\n \u0026lt; 0.17% at 20 kHz, at 300 W, 8 Ω \u003cbr\u003e\u003cbr\u003e\n\nInput impedance:\u003cbr\u003e\n Single-ended: 100 kΩ \u003cbr\u003e\nBalanced: 200 kΩ \u003cbr\u003e\u003cbr\u003e\n\nInput sensitivity: Single-ended or balanced: 2.4 V RMS\u003cbr\u003e\nOutput power: 300 W RMS at 8 Ω \/ 540 W RMS at 4 Ω \u003cbr\u003e\nOutput voltage:  138 V peak-to-peak \/  49 V RMS\u003cbr\u003e\nOutput current:  16 A peak\u003cbr\u003e\nSlew rate:  40 V\/μs\u003cbr\u003e\nOutput impedance:  \u0026lt; 0.007Ω, 20 Hz to 20 kHz\u003cbr\u003e\nDamping factor:  \u0026gt; 1140, 20 Hz to 20 kHz, referred to 8W\u003cbr\u003e\u003cbr\u003e\nPower consumption:\u003cbr\u003e\n Standby: 4 W\u003cbr\u003e\nIdle: 200 W\u003cbr\u003e\n Maximum: 2160 W\u003cbr\u003e\u003cbr\u003e\n\nHeat output: \u0026lt; Standby: 13.7 BTU\/hr.\u003cbr\u003e\n Idle: 800 BTU\/hr.\u003cbr\u003e\n Maximum: 7387 BTU\/hr.\u003cbr\u003e\u003cbr\u003e\n\nInputs:\u003cbr\u003e\n 3 single-ended via RCA connector\u003cbr\u003e\n 3 balanced via XLR connector\u003cbr\u003e\u003cbr\u003e\n\nOutputs:\u003cbr\u003e\n 3 pairs binding posts\n\u003cbr\u003e\u003cbr\u003e\nDimensions: 17.1 in.
