Digigram Shows EtherSpeaker Technology at AES
 December 4, 2001Digigram released EtherSpeaker V1.0 networked speaker technology at
AES 2001.
EtherSpeaker V1.0 enhances established technologies to easily and economically create audio networks using
standard Ethernet cabling and components. The EtherSpeaker V1.0 development module is designed to
connect a digital audio source to speakers. Up to 32 channels of 24-bit digital audio, plus control information,
may be transported to a virtually infinite number of speakers.
Networked speaker modules may be connected serially. A virtually unlimited number of modules may be
daisy-chained. Modules may be up to 100 meters apart with no limitation on the distance between the first and
last modules in the chain. Because EtherSpeaker V1.0 is compatible with Ethernet 802.3 and 100BaseTX
full-duplex standards, off-the-shelf Ethernet switches may be used to distribute EtherSpeaker transmissions to
networked speaker demonstration modules. Switches may be used to facilitate complex network architecture
and extend the distance between modules.
"Configuration and set-up are simpler than analog systems," said Philippe Girard-Buttoz, president of Digigram,
S.A. "In public address and home audio installations, EtherSpeaker reduces installation costs and maintains a
fully digital path to every speaker."
Connecting the audio source is accomplished using four, industry standard Synchronous Serial Interfaces built
into the module.
The networked speaker demonstration module is just one implementation of EtherSpeaker V1.0 technology.
Additionally, EtherSpeaker technology is available for licensing for OEM applications.
