ARX-400

Description

The ARX-400 Analog Reference Series amplifier is a two-channel system designed to bring out the finest performance from any pair of high-quality reference monitors or playback speakers. It delivers 400 pristine watts into 8 ohms along with ultra-fast transient response, lowest possible distortion and self-noise levels and warm and natural sound reproduction.

The ARX-400 will bring new life to near- and mid-field monitoring environments and improve accuracy in sound production and provide an enjoyable and enhanced listening experience.

Housed in a rugged 2U chassis, the recognizable and attractive Augspurger-red face plate sports a standby power switch and two multi-functional LED indicators. Rear connections are via gold-plated professional-quality unbalanced RCA connectors and metal shell XLRs while output connectors are heavy-duty gold-plated banana connectors/binding posts.
