Digital-fibre specialist Optocore has agreed with fellow German manufacturer Fohhn Audio to provide multi-channel digital connectivity to its Linea Focus electronically steerable loudspeakers.

Fohhn’s public relations and marketing manager Daniela Bohl said: “We were looking to provide our speaker systems with a digital signal and control data. Up to now we had only an analogue solution. We chose Optocore because it is a pioneer of that technology and there is a perfect fit between our two companies: we are both innovation-driven and German based.”

In order to provide integration on to the Optocore networks, the fibre specialist has created a special card. Meanwhile Fohhn has developed a purpose enclosure, which can be attached to its Linea Focus series loudspeakers to provide optional input extensions. This will enable digital audio and control data to be distributed simultaneously, either via Cat5 or optical fibre.

Daniela adds: “These Optocore extensions will provide excellent audio quality and entire control of the speaker. They will also facilitate reliable and redundant digital audio network. We are looking forward to integrating the Optocore technology into our electronically steerable Linea Focus and are excited about the cooperation and the possibilities resulting from it.”

Masterminding the project for Optocore, applications engineering manager Maciek Janiszewski says of the cards, which come in fibre Optocore FX and Cat5 SANE TP versions: “Each card will provide two outputs to feed loudspeakers with two independent audio signals, RS485 port for control and GPIO.
All these signals can be transported on single-fibre or Cat5 cable.

“The Fibre FX version enables all speakers to operate on an Optocore fibre ring with all other devices from the Optocore portfolio as well as third party products with an Optocore interface. The distance between loudspeakers can be up to 120km. The Cat5 SANE TP version can be a local extension to the fibre node, enabling users to build local daisy chains with 100m distance between the loudspeakers.

“This card adds huge flexibility to Fohhn solutions, simplifies cabling and adds quality by reducing signal losses over coax. Both companies will benefit from this cooperation: Optocore will raise its profile in the installed sound sector, especially in transportation hubs – large-scale PA systems in railway stations and airports – while Fohhn will be able to offer the best signal transport solution as well as distributed routing and redundancy.”
