Description
Accuphase E-480 Integrated Amplifier
The new Accuphase E-480 is a new-generation integrated amplifier that comes close to the performance of separate Pre/Power system. It has a whole new front panel design including the button array inside the sub-panel. Needle power meter with indication range to -50dB is able to move even at the small volume level less than – 60dB. The Sampling Frequency Display has expanded to “MHz” to support the DAC-50. The E-480 takes the mono block construction. With the symmetrical arrangement of L / R power amplifier blocks, strong power supply with a massive high-efficiency toroidal transformer and two large 40000μF specially- made filtering capacitors are installed at the centre of unit.
The rated output power of E-480 is 180W into 8Ω load, 260W into 4Ω load. The actual maximum output power achieves 290W into 4Ω load. The AAVA (Accuphase Analog Vari-gain Amplifier) is a volume control principle that eliminates all variable resistors from the signal path. This is Accuphase unique technology. The AAVA module in E-480 achieves low noise by the fourth paralleled largest unit and the paralleled second largest unit in “V to I” converters. This improvement helps to make the V-I converter amp’s output current double, and it results in reducing the value of the feedback resistors and the noise coming from them.
Power amplifier sections contain same circuit configuration as Class-A stereo power amp. A-75. The output impedance is decreased by 3 parallel push- pull final stage arrangement of MOS-FETs. The E-480 mounts the new power MOS-FET device which is heavy-duty and has the large absolute maximum ratings. **Absolute maximum ratings of power MOS-FET E-470’s MOS-FET: 180V / 10A
E-480’s MOS-FET: 200V / 12A
