DYNACORD presents the RCM-8 module with OMNEO network technology

DYNACORD presents the RCM-28 module with OMNEO network technology 18 Apr 2013

In the RCM-28 DSP and network module, DYNACORD is presenting a new development for its PowerH power amplifiers. The RCM-28 is a dual channel, digital controller module, which in addition to numerous DSP functions also boasts a redundantly implemented OMNEO network interface. Via IRIS-Net software, all of the PowerH amplifier's network and system parameters can be supervised and controlled remotely.

The RCM-28 module is the first DYNACORD product to support the new media network architecture OMNEO. With RCM-28 modules, PowerH series amplifiers can be integrated within OMNEO networks with up to 100 other devices without additional hardware. OMNEO is based on two key technologies: the media transmission component Dante from Audinate and the system-control component OCA (Open Control Architecture) developed by Bosch Security Systems together with the OCA Alliance. In combination, these allow the transmission of audio, and in the future also video, formats as well as the control of all devices via standard Ethernet with standardized protocols.

The RCM-28 offers a digital AES 3 (AES/EBU) input with a loop-through possibility and a dynamic range of 128 dB, whilst two analogue inputs and the same number of analogue outputs are available via XLR connections (116 dB SNR). The transmission of several hundred audio channels is possible over the network. Furthermore, in each case two input and output signals in OMNEO/Dante format, with a sampling rate of 48 kHz, can be received or transmitted. A third additional channel can also be transmitted for remotely monitoring the audio signal path at the amplifier. The module covers the frequency range from 20 Hz to 20 kHz, the internal latency being 1.5 ms (AES 3 In / Analogue Out) and 2.375 ms (Analogue In / Out) respectively. The A/D and D/A converters operate in 24-bit resolution and the DSP processing of the 500 MIPS dual core processors is performed in 48-bit resolution.

For signal processing, in addition to standard functions, multi-band parametric equalizers, delays for inputs and outputs as well as additional FIR filters on the output side, crossovers and limiters are all available. Serving as interfaces are two RJ-45 ports for the OMNEO network and four freely configurable GPIO control ports (2 x GP1, 2 x GPO).

With OMNEO, we are offering our customers the possibility of using fully standardized media networks within which not only DYNACORD equipment but also the products of a variety of other manufacturers can interact seamlessly with one another, says Ethan Wetzell, Platform Strategist with Bosch Security Systems and Global Product Manager for DSP. We are harmonizing our solutions with newly emerging standards such as AVB (Audio Video Bridging) in order to create a standardized Ethernet infrastructure for every possible type and size of application. OMNEO will play a leading role in future in both system design and that of new products, so we are delighted to be presenting in the RCM-28 the first of many new OMNEO products.
