Product Description

Arcam P429 is designed to offer impressive flexibility for various applications as well as using latest generation class G topology that is both clever and efficient. During normal operation, distortion is measured in less than one part per million so that this massive power is delivered with total control and finesse.

Engineering

Drawing on the many years of amplifier design experience at Arcam, the P429 uses the best quality components and engineering practice to develop a product that will give many years of musical pleasure and reliable service. With a class G amplifier, toroidal transformer based power supply, acoustically damped chassis, complementary transistor output stages, exceptionally low levels of distortion and noise the P429 is capable of reproducing music with all its original authority and detail. Rest assured you will be hearing the music just as the artist intended.

Class G Amplification

Like a hybrid car engine, Class G implements multiple power supplies rather than just a single supply. If a dynamic signal is received that goes beyond the capability of this first power supply, the secondary supply is gradually introduced up to full rated power output as required. This gives a very efficient design as additional power is only used when required, much like a turbocharger. Modern high-speed silicon makes this switch faster than would ever be required, even way beyond the audio bandwidth, so there is no “turbo lag”.

The first power supply has lower power and runs in pure Class A, which has no crossover distortion. As the secondary supply is only used when required, extreme levels of power are possible because very little energy is wasted in the amplifier as heat when it is not being used. To control this power, multiple output devices within the amplifier keep a tight grip on the loudspeaker at all times.

AV or Stereo

AV enthusiasts will love the ability to add matching class G amplification to their AVR390, AVR550 or AV850 for a full 7.1.4 Dolby Atmos setup. Stereo fans will appreciate the bridged mode of operation, which allows up to 270W power output per channel. Installer-friendly features like IP & RS232 control, 12V In/Out triggers, individual channel trims make the P429 the perfect choice for the installer.

Must Audition

There have been great strides made in improving audio sources and loudspeakers in recent years and the time is right to match them in the field of amplifier design. This groundbreaking amplifier is a “must audition” amplifier for music lovers who understand that power is nothing without control.
