Multichannel amplifier 12 x 400W channels

The Amp400.12 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 Amp400.12 was mainly developed for immersive audio, nothing prevents using it for other multichannel applications as well. As all 12 channels are identical and discreet they can also used to power up to 6 stereo pairs of passive speakers. It will equally drive both 8 ohm and 4 ohm loads, and partners
perfectly with all Amphion models. Though Amp400.12 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.
Low-distortion power
Amp400.12 delivers rock-solid control and tight, fast, highly resolving low-distortion power to get maximum performance from your monitors.

Added performance
To reach the needed sonic performance, a proprietary in-house designed buffer stage compliments the merits of the latest Class-D technology.

The perfect partner
Careful sonic matching and quality components make the amplifiers a perfect partner to all Amphion monitors and other passive speakers.
