Introduction
Thank you for choosing Amphion Amp400.8
Amphion’s philosophy is to develop innovative products with high-performance and longevity. The
Amphion Amp400.8 is a highly synergistic pairing of the very latest in Class-D engineering and
Amphion´s in-house designed buffer stage. The buffer stage brings a touch of magic to an already
excellent multi-channel platform. Exceptionally high price/performance ratio was achieved by focusing
on the sonics and omitting everything which was not totally necessary.
We hope you enjoy listening to your new amplifier as much as we enjoyed developing it.
The Amp400.8
The Amp400.8 provides an exceptional level of multichannel amplification. It is built on the highly
advanced Class-D platform, which offers abundant, fast, controlled, and low distortion power. To
reach the needed sonic character and performance, an in-house designed buffer-stage was added
to complement the merits of the latest Class-D technology. The buffer stage improves the impedance
characteristics and cohesion between the channels, so that speed, control, neutrality, and ultra-low
distortion can come across in an emotionally involving manner.
Though Amp400.8 was mainly developed for immersive audio, nothing prevents using it for
other multichannel applications as well. As all 8 channels are identical and discreet it can also also
be used in a 2-channel environment for driving up to 4 pairs of passive speakers. It will equally drive
both 8 ohm and 4 ohm loads, and partners perfectly with all Amphion models. Though Amp400.8
was developed and optimized for Amphion monitors, it provides excellent results with wide range of
passive speakers. Neutrik XLR and Speakon connectors offer a convenient and secure way to connect
the amplifier to rest of the system.
