Israel's Center for Accessible Culture Selects DHD SX2 Radio Consoles

Israel's Center for Accessible Culture, formerly known as the Central Library for the Blind (CLFB), has chosen DHD SX2 radio consoles as the core of a studio modernisation project at its headquarters in Tel Aviv.

The new system was integrated by Jerusalem-based audio technology specialist Broadcast Design Ltd.

"The Center for Accessible Culture makes classical literature, periodicals and textbooks accessible to blind, visually impaired and handicapped people," said Broadcast Design founder and CEO Micha Blum. "The organisation's technical operations team were keen to replace outdated equipment and contacted us to ask if we could provide a system that conformed to the existing workflow.

"A key challenge was how to provide visually impaired members of the production team with a solution that was really easy for them to use. We set up a demo studio based on a DHD SX2 control module plus an XC3 IP core. The SX2 has a larger number of physical buttons allowing customisable direct access which was important for visually impaired operators. Additional features included Audio over IP studio connectivity using Audinate Dante.

"We left the demo system onsite for several weeks during which it proved popular with sighted and sight-impaired CLFB operators as well as the technical support team. Three complete systems were ordered for use across nine studios. The system is configured as one fader per studio, each on its own bus. This proved easy and flexible for the CLFB team to use. Physical faders and buttons are ideal in this application. DHD’s Assist App potentially allows a technician to provide online support even from home via a browser-based mixer control license. Each narrator has access to a cough-mute button with a clear indication that this has been activated.

"An important factor as to why we chose DHD systems is that they are highly customisable. It is very easy to configure a channel strip with direct talkback-on and playback-mute per studio. On top of this came a request for precise control of the balance of multiple loudspeakers in each control room and playback level from a PC workstation in each room. All of this was configured perfectly in just a few minutes.

"The DHD system is so flexible that we were even able to give each control button a unique identifying sound so that it could be used with confidence by a non-sighted operator. All of this is achievable within the DHD system by configuration.

"The inclusion of AoIP into the facility opened new options like the ability to record to any specific studio from any computer. It also allowed backup recording, including a server which can capture the output from all studios at once."

"Micha Blum and his colleagues have made very good use of the configuration versatility inherent in our audio production control surfaces, processing cores and supporting software," added Marc Herrmann, Managing Director of DHD audio. "We are confident that the audible control identifiers will be of interest to other vision-impaired media production staff, not least among the many talking-book service providers around the world."

DHD's SX2 console is based on a four-fader central module. Integral display screens allow operators to see exactly how their console is performing both from connectivity and signal level perspectives. The central module gives access to the most important audio inputs and outputs. A microphone input and headphone output are included, and loudspeakers can be connected directly to this unit. The consoles can be expanded by adding one or more module with six motorised faders each. Central and fader modules each incorporate a 10.1 inch multi-touch display showing relevant configuration and operating parameters. Functions such as loudness metering and talkback to other DHD mixers are also supported.
