Accuphase E-3000 Integrated Stereo Amplifier

The E-3000 is an integrated amplifier that inherits the technology of high-end models and has expressive power and a variety of functions that go beyond its class.

By adding the optional DAC-60 digital input board and AD-60 analog phono stage board, you can enjoy high-quality playback of digital music signals and analog discs.

Option Boards

A range of sophisticated option boards opens up even more possibilities. The Accuphase DAC Input Board features a USB port and support for high-bit, high-sampling frequency signals up to 192 kHz/24 bits. The newly developed Analog Disc Input Board AD-50 is also available, ideal for high-grade reproduction of analog records using either MC or MM phono cartridges.
Balanced AAVA Volume Control

Conventional 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-4000 with its balanced AAVA circuits delivers exceptional noise suppression performance. FEATURES

• Improved AAVA volume control for ultra low noise levels

• Power transistor, 4 parallel push-pull Class AB operation

• Damping factor of 800

• High power of output 180W/8Ω, 260W/4Ω

• Speaker output protection circuit to prevent short circuits

• Strong power supply with a massive high-efficiency toroidal transformer and large filtering capacitors

• Play high-resolution audio sources from digital devices with the digital input board DAC-60 (sold separately)

• Play analog records with the AD-50 analog disk input board (sold separately) Specifications
