This results in a highly linear and extended frequency response, well beyond the range of hearing, for smooth effortless highs and tight high impact bass.\u003cbr\u003e\u003cbr\u003e\n\nThe power supply consists of two 787VA toroidal transformers and 160,000uF of capacitance. This is shared among all the channels so all of that power is available to the channels with the most demand.\u003cbr\u003e\u003cbr\u003e\n\nIn real world conditions the left, right, and center channels require the lion’s share of the power so this gives the Theater 7 a more effective power supply than other amplifiers that have smaller dedicated power supplies for each channel.\u003cbr\u003e\u003cbr\u003e\n\nFrequency response:\u003cbr\u003e\n 20 Hz to 20 kHz +0, –0.11 dB\u003cbr\u003e\n \u0026lt; 3 Hz to 200 kHz +0, –3 dB\u003cbr\u003e\u003cbr\u003e\n\nSignal-to-noise ratio:\u003cbr\u003e\n \u0026gt; 101 dB, wideband, unweighted, referred to full power output\u003cbr\u003e\n \u0026gt; 114 dB, “A”-weighted\u003cbr\u003e\u003cbr\u003e\n\nGain: 25.5 dB\u003cbr\u003e\u003cbr\u003e\n\nTotal harmonic distortion:\u003cbr\u003e\n \u0026lt; 0.02% at 1 kHz, at 100 W, 8 Ω, two channels driven;\u003cbr\u003e \n \u0026lt; 0.20% at 20 kHz, at 100 W, 8 Ω, two channels driven; \u003cbr\u003e\u003cbr\u003e\n\nInput impedance:\u003cbr\u003e\n Single-ended: 27 kΩ; \u003cbr\u003e\nBalanced: 54 kΩ; \u003cbr\u003e\u003cbr\u003e\n\nInput sensitivity: Single-ended or balanced: 1.50 V RMS\u003cbr\u003e\u003cbr\u003e\n\nOutput power, per channel:\u003cbr\u003e\n 120W RMS at 8 Ω, 2 channels driven\u003cbr\u003e\n 115W RMS at 8 Ω, 3 channels driven\u003cbr\u003e\n 110W RMS at 8 Ω, 5 channels driven\u003cbr\u003e\n 105W RMS at 8 Ω, 7 channels driven\u003cbr\u003e\n 210W RMS at 4 Ω, 2 channels driven\u003cbr\u003e\n 190W RMS at 4 Ω, 3 channels driven\u003cbr\u003e\n 165W RMS at 4 Ω, 5 channels driven\u003cbr\u003e\n 140W RMS at 4 Ω, 7 channels driven\u003cbr\u003e\u003cbr\u003e\n\nOutput voltage:\u003cbr\u003e\n 93 V peak-to-peak\u003cbr\u003e\n 33 V RMS\u003cbr\u003e\u003cbr\u003e\n\nOutput current:  10 A peak\u003cbr\u003e\n\nOutput impedance:  \u0026lt; 0.025 Ω, 20 Hz to 20 kHz\u003cbr\u003e\n\nDamping factor:  \u0026gt; 320, 20 Hz to 20 kHz, referred to 8 Ω\u003cbr\u003e\u003cbr\u003e\n\nPower consumption:\u003cbr\u003e\n Standby: 1 W\u003cbr\u003e\nIdle: 66 W\u003cbr\u003e\n Maximum: 2000 W\u003cbr\u003e\u003cbr\u003e\n\nHeat output:\u003cbr\u003e\n Standby: 3.42 BTU\/hr.\u003cbr\u003e\n Idle: 225 BTU\/hr.\u003cbr\u003e\n Maximum: 2200 BTU\/hr.\u003cbr\u003e\u003cbr\u003e\n\nInputs:\u003cbr\u003e\n 7 single-ended via RCA connector\u003cbr\u003e\n 7 balanced via XLR connector\u003cbr\u003e\u003cbr\u003e\n\nOutputs:\u003cbr\u003e\n 7 pairs five-way binding posts\u003cbr\u003e\u003cbr\u003e\n\nRemote connectors:\u003cbr\u003e\n One 12 VDC input (12 V trigger) via 3.5 mm jack \u003cbr\u003e\u003cbr\u003e\n\nDimensions:\u003cbr\u003e \n 17.1 in.
