The A-40AE by Pioneer incorporates an isolated power supply, specially designed large capacitors, Direct Function operation, and Power Amp Direct Mode. It features an MM Phono input and many other elements that deliver clear, dynamic, and high-quality sound.

Direct Energy Design/Direct Energy Construction

Pioneer's Direct Energy Design is based on the concept of Direct Energy—the loss of energy from the amplifier to the speakers. The latest integrated amplifiers feature optimized power supplies and output circuit layouts, resulting in excellent signal transfer and a high signal-to-noise ratio.

Isolated Power Supply

The windings for the power amplifier, pre-amplifier, and controls are separate within the power transformer to prevent mutual noise interference.

Pioneer-Exclusive Electrolytic Capacitors

The main capacitor, which determines the sound quality of an amplifier, has been developed in collaboration with ELNA and features the Pioneer logo.

Direct Function

The Direct Function bypasses other circuits except for the volume control, offering a pure listening experience.

Power Amp Direct Mode

With the power amp direct input, an external pre-amplifier can be connected, using the unit as a power amplifier in a multi-channel setup.

Anti-Standing Wave Insulators

The Anti-Standing Wave insulators have a special shape without parallel sides, preventing hollow resonance.

Non-Magnetic Material Speaker Terminals

The speaker terminals are made from non-magnetic materials, reducing external noise and delivering high-purity signals.

Phono (MM) Input

The A-40AE features a phono input (MM) for connecting a turntable, enjoying quality sound performance from vinyl records.

Digital Inputs

The optical and coaxial digital inputs allow connection to a TV or other audio devices with Hi-Res Audio support.

Aluminium Volume Knob and Front Panel

The A-40AE features an aluminum volume knob and a simple front panel for elegance in the audio experience.

Auto Standby

The integrated amplifier automatically switches to standby mode after 20 minutes without audio input.
