Amphion Amp400.12

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.

Although 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 it can 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.

Amp400.12 was developed and optimised for Amphion monitors, but it also 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.

Amp400 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.
