OMNEO Network and DSP Module for Tour Grade Amplifiers

The Electro Voice RCM-28 Remote Control Module is a two-channel digital controller module for live sound reinforcement, PA and fixed installation applications. The module can be used in Electro-Voice Tour Grade amplifier models. Installing the RCM-28 turns a conventional amp into a remote amplifier, which, at any time, provides complete overview of the overall system status and control of all system parameters. RCM-28 modules allow the integration of amplifiers into an OMNEO network with up to 100 devices in a single subnet without additional hardware. OMNEO is a media networking architecture for professional applications. Using standard IP Ethernets, media products that integrate OMNEO can be assembled into networks of 2 to 10,000 cooperating devices that exchange studio-quality synchronized multichannel audio and share common control systems. This offers the possibility to control and monitor an entire sound system from one or more PCs using the IRIS-Net - Intelligent Remote & Integrated Supervision - software package. In addition to digital signal processing functions, the RCM-28 also offers a digital audio input (AES/EBU), OMNEO network audio inputs and outputs, and freely programmable control inputs and control outputs.

RCM-28 features include:

  • OMNEO Network Interface
  • Extend Tour Grade performance with powerful DSP functionality
  • Advanced FIR-Drive loudspeaker optimization
  • High precision load impedance supervision
  • Two GPI and two GPO ports
  • One-button system test for fast, complete check of connected cables and components
  • Pilot tone detection for cable supervision
  • Six recallable DSP/configuration presets
  • Compatibility with any Dante network
