The RMS-20K has been designed to supply the voltage required by the highest performance loudspeakers in the Pro audio industry. Nearly 1000 Joules of stored energy ensures the deepest bass extension, while delivering a tight, dynamic, transparent and natural response. The amp is capable of driving high and low impedance loads, and features a variety of input signal connectivity, making the platform suitable for both live applications and fixed installations.

The platform features a 96kHz sample rate, end to end 64 bit double precision signal processing, low latency DSP with fixed through time (non FIR), advanced FIR capability ( up to 1000 tap per channel), extensive multi Layer IIR filtering, multi stage limiting, robust grouping and management for large system implementations.

The RMS-ACOUSTICS amplifiers contain an extensive library of RMS loudspeaker Presets and System Snapshot configuration, as well as the ability for third party designers or engineers to create their own presets, snapshots, and libraries of both.

A large, capacitive IPS touch display enables level monitoring, quick recall, and configuration in the field via the front panel without the need for computer software.

The RMS-20K features a mixed signal 4 channel input routing matrix, able to individually configure any input as analog, AES, or DANTE. Any of the the four inputs can be individually routed to any of the four output channels.

The RMS-20K can be controlled and managed remotely via ethernet through the RMS-CONTROL software platform. An onboard Ethernet switch inside each amp enables daisy chain connections between multiple RMS amplifiers for small networks. Standby, gain, and mute controls are also available over a network API for custom software integrations, including QSYS.

Onboard enhanced energy saving features, power efficiency and remote Wake up enable you to save energy toward meeting environmental responsibility requirements. The wide range switching power supply allows operation on mains voltages from 90 to 265 volts. With active power factor correction (PFC), mains power efficiency is further improved.

Utilizing the latest generation of Class D topology, the RMS Amplifiers achieve very high efficiency (greater than 90%) under all loads while minimizing waste heat output. A temperature-controlled variable speed fan dissipates heat to the rear, with a washable/replaceable filter in the front. The already low idle power consumption can be reduced to below 5W by a remotely switchable standby mode.

The RMS-ACOUSTICS amplifiers can be configured to deliver their maximum power into a variety of load impedances, down to 2 ohms, as well as high-Z 100V/70V/50V/35V systems. The advanced power control management PCM™ provides the most efficient availability of the full frame power to all channels under differing and dynamic loads.
