Detailed Description

Intuitive User Experience

The 4040 A offers a highly intuitive user interface, allowing users to effortlessly control and fine-tune their audio settings via two rotary knobs or a convenient infra-red remote control. The sophisticated menu system ensures a seamless and user-friendly operation.

High-Quality Pre-Amplifier Section

Designed for flexibility, the 4040 A includes three analogue inputs, consisting of two RCA unbalanced inputs and one balanced XLR input that can be used in single-ended mode. The electronic volume control provides a wide adjustment range with precise 1dB increments, ensuring detailed and accurate level control. Additionally, built-in EQ controls enable fine-tuning of bass and treble response for a personalized listening experience.

Vinyl Playback Enhancement

For vinyl enthusiasts, the 4040 A supports an optional Sequel mk4 Phono pre-amp, replacing Line 2 input, to cater to a broad spectrum of Moving Magnet and high-output Moving Coil cartridges.

Headphone Amplification

With a high-current, low-distortion headphone amplifier, the 4040 A delivers an exceptional personal listening experience. The front-mounted 6.35mm (1/4”) jack output ensures compatibility with a variety of headphone models, providing ample power and clarity.

Digital Connectivity and DAC

The 4040 A features a variety of digital inputs, including coaxial SPDIF, optical TOSLINK, USB class 2, and aptX Bluetooth 5.0, allowing seamless connection to music streamers, TVs, CD transports, and computers. Digital signals are converted to high-quality analogue output using the 32-bit ES9018k2m Sabre32 DAC, ensuring pristine audio reproduction.

Advanced Power Amplification

At the heart of the 4040 A is cutting-edge MERUS™ Infineon technology, designed to drive even the most challenging speaker loads with remarkable fidelity. The power amplifier can also be driven directly via Line 1 input for additional system flexibility.

High-Frequency Power Supply

Unlike conventional amplifiers, the 4040 A incorporates a voltage-stabilized 350W power supply, which maintains consistent performance irrespective of mains quality or voltage fluctuations. This ensures that the amplifier can double its power output into half the load impedance without compromise.

Energy-Efficient Standby Mode

The 4040 A reduces energy consumption by deactivating non-essential circuitry when idle. Users can customize auto-standby timing to 30, 60, or 120 minutes or disable it entirely for continuous operation.
