The Accuphase E-5000 integrated amplifier stands as a testament to the pinnacle of audio engineering. This masterpiece combines power, precision, and timeless elegance to deliver an unparalleled listening experience.At the heart of the E-5000 lies a fully balanced Class-A amplifier circuit, ensuring exceptional linearity and low distortion. The amplifier's power supply is meticulously designed to provide clean, stable energy, even during demanding listening sessions. The result is a sound that is both dynamic and controlled, capable of revealing the subtle nuances of any recording.Balanced AAVA Volume ControlConventional preamplifiers use variable resistors to adjust volume, which causes contacts to deteriorate and create grit as well as increase noise at normal volume levels. AAVA, however, produces multiple, widely varying signals from the input signal and controls volume by changing the combination of those signals. This achieves minimum noise at all volume levels without any grit. The E-5000 with its balanced AAVA circuits delivers exceptional noise suppression performance.Formidable Power Amplification StageThe power amplification stage on both the left and right sides is equipped with a large heat sink and employs five-fold parallel push-pull power transistors driven in Class AB to provide rated, high-power output of 240 watts into 8 ohms and 320 watts into 4 ohms.High damping factorThe damping factor represents the amplifier's ability to drive the speakers. A damping factor of 1,000 (guaranteed) extracts the maximum potential from the loudspeakers.Power supply circuitry designed for optimum stabilityA strong power supply featuring a massive toroidal transformer and two high-voltage, large filtering capacitors (40,000 μF/100 V) offers a stable power supply at all times.SpecificationsContinuous Average Output Power (both channels driven, 20-20,000 Hz): 320 watts per channel into 4 ohm, 240 watts per channel into 8 ohmsIntermodulation Distortion: 0.01%Frequency Response: HIGH LEVEL INPUT/POWER INPUT 20 - 20,000 Hz +0, -0.5 dB (for rated continuous average output), 3 - 150,000 Hz +0, -3.0 dB (for 1 watt output)Damping Factor: 1000 (For rated output with 8-ohm load, 50 Hz)Output Voltage, Output Impedance (at rated continuous average output): PRE OUTPUT: 1.74 V, 50 ohmsGain: HIGH LEVEL INPUT → PRE OUTPUT: 18 dB, POWER INPUT → OUTPUT: 28 dBTone Controls Turnover frequency and adjustment range: BASS: 300 Hz ±10 dB (50 Hz), TREBLE: 3 kHz ±10 dB (20 kHz)Loudness Compensation: +6 dB (100 Hz)Attenuator: -20 dBPower Level Meters: Logarithmic compression, peak reading meters, output dB/% scaleLoad Impedance: 4 - 16 ohmsStereo Headphones: Suitable impedance: 8 ohms or higherPower Requirements: AC 120 V/220 V/230 V 50/60 Hz (Voltage as indicated on rear panel)Power Consumption: 98 watts idle, 570 watts in accordance with IEC 60065Maximum Dimensions: Width 465 mm x Height 211 mm x Depth 502 mmMass: 33.8 kg net, 45 kg in shipping carton
