ALC NetworX, developer of the Technology & Engineering Emmy® Award-winning RAVENNA technology, is pleased to welcome British pro audio tools and interface experts, Nixer Pro Audio, as the latest RAVENNA partner.

Based in Dunstable in the UK, Nixer Pro Audio specialises in the design and development of professional AoIP monitoring, mixing and diagnostics solutions. Founder and CEO Nick Fletcher has an impressive pedigree in product design and development, having spent over 30 years designing and building equipment, including over a decade as director of R&D at Cadac.

“We already have a number of products built on the Dante protocol, but our new RL Series (launched in June) was specifically designed to have RAVENNA capability in response to requests from customers within the broadcast market,” explains Fletcher.

RL Series is a range of 1U rack-mounted AoIP mixing and monitoring units available in 64, 128, 192 and 256-channel versions, configurable at purchase to be either RAVENNA or Dante. RL Series units allow two modes of operation: a mixing mode which can mix up to 256 channels at 48kHz (128 channels at 96kHz) plus a microphone input (via headphone connector) and AES input to create a 259-into-2 mixer; alternatively, it can be set into a simple listen mode where touching a channel instantly routes to the L/R output and cancels any previous selection.

An elegantly simple menu system offers rapid, easy and intuitive access to all the unit’s features via a touchscreen interface and the high-resolution screen is easy to read, presenting the user with comprehensive metering, routing and status information.

“Given that RAVENNA is now an integral part of our product range, becoming a RAVENNA partner seemed the logical option in order to keep ourselves and customers updated on all Audio-over-IP developments,” observes Fletcher.

Andreas Hildebrand, RAVENNA Evangelist at ALC NetworX, is pleased to welcome Nixer Pro Audio on board: “I am glad to welcome Nixer Pro Audio to our ranks, particularly in light of the fact that their broadcast customers have specifically requested RAVENNA capability. It is testament to the fact that when only the highest audio quality will suffice, the choice for audio transport has to be RAVENNA, and I am sure that RAVENNA capability will be implemented in many more Nixer Pro Audio products in the future.”

RAVENNA is a technology for real-time distribution of audio and other media content in IP-based network environments. Utilizing standardized network protocols and technologies, RAVENNA can operate on existing network infrastructures. RAVENNA is designed to meet the strict requirements of the pro audio market featuring low latency, full signal transparency and high reliability.

While primarily targeting the professional broadcast market, RAVENNA is also suitable for deployment in other pro audio market segments like live sound, fixed installations, and recording. Possible fields of application include (but are not limited to) in-house signal distribution in broadcasting houses, theaters, concert halls and other fixed installations, flexible setups at venues and live events, OB van support, inter-facility links across WAN connections and production & recording applications.

Unlike most other existing networking solutions, RAVENNA is an open technology standard with no proprietary licensing policy. RAVENNA is fully compatible with the AES67 and ST2110 standards. Liaisons with standards organizations and industry alliances (e.g. AES, AIMS, AMWA, SMPTE and others) ensure the close alignment of RAVENNA technology with current industry trends.
