4040 A
Integrated Amplifier + DAC
“The 40th anniversary 4040 A integrated amplifier will suit the most demanding applications. Whether used in a domestic audio or desktop system, the feature-rich 4040 A is simple to use, yet luxurious in operation. Created to provide a totally immersive high-end experience”
“With five decades’ experience in the audio business, I have seen a lot of electronic developments in my time, but I am really excited about this major step forward in technology and musical performance”
Mike Creek – Creek Audio
The all-new 4040 A integrated amplifier has been designed to reprise the essence of the original CAS4040 which was launched in 1982 to critical acclaim. While huge technological advances and modern digital features have propelled the 4040 A into the 21st century, it continues to release the same endorphins its ancestor did 40 years ago.
CONTROL
The 4040 A’s intuitive user interface and sophisticated menu system are easily navigated by two rotary control knobs or infra-red remote control
PRE-AMPLIFIER
The “feature-rich” 4040 A contains three analogue signal inputs, including two pairs of unbalanced RCA sockets and one pair of fully balanced XLR sockets, that can still be used single-ended. An electronic volume and balance control enables precise 1dB adjustments over a 70dB range. Tone controls (EQ) enable +/- 10dBs adjustment of treble and bass.
PHONO
Vinyl music lovers may plug-in an optional Sequel mk4 Phono pre-amp in place of Line 2 to match a wide range of Moving Magnet and high output Moving Coil cartridges found on modern turntables.
HEADPHONES
A high current, low distortion headphone amplifier drives a wide range of low-impedance headphones via a front panel-mounted 6.35mm (1/4”) jack socket.
DIGITAL INPUTS
Coaxial SPDIF, optical TOSLINK, USB class 2 and aptX Bluetooth 5.0 enables digital sources, such as music streamers, TVs, CD transports, computers, and wireless Bluetooth devices to be connected.
DAC
PCM and DSD digital audio signals are converted to analogue with a reference quality 32-bit ES9018k2m Sabre32 DAC.
POWER AMPLIFIER
The 4040 A employs cutting-edge MERUS™ Infineon technology enabling it to drive even the most difficult loads to realistic listening levels with high fidelity. The power amp may be driven directly via Line 1.
POWER SUPPLY
The key to the integrated amplifier’s impressive performance is in its high-frequency power supply, optimised for audio electronics, enabling the latent quality of its amplifier to be realised. The performance is unaffected by mains quality or voltage stability. Unlike most conventional amplifiers, the 4040 A’s 350-Watt power supply is voltage stabilised, enabling it to double its power output into half the load impedance, regardless of the mains voltage.
