Mayah Details New C11 Codec Line

Introduces it at IBC and NAB Radio Show.

Mayah is providing more info about its new C11 product family, being introduced this month at IBC and the NAB Radio Show.

The codec line will have 14 models; the company emphasizes their small size, silent operation and efficiency.

Each C11 codec fits in half of a 19 inch rack width and is 1RU high. They are stackable for use in bigger installations and require no forced cooling; they consume 8W of power.

All provide audio over IP with SIP/RTP according to the EBU N/ACIP standard, Mayah said, resulting in broad interoperability with standard-based IP codecs of various manufacturers. The C11 supports an automatic optimization of the IP connection.

The C1140/1 and C1160/1 models are provided with four ISDN BRIs. Dual Ethernet interface of the C1190/1 can be used for redundant streaming or for separation of streaming and control. Also available is a C1180/1 audio encoder with ASI interface to deploy it in the DVB environment.

With optional interface cards C11 can be turned to a POTS codec; it can transmit and receive audio over wireless 3G/UMTS network. Some models allow simultaneous transmission and audio logging onto an SD card or USB memory stick. “It opens a door for the highly customized system solutions for emergency backup, regionalization, local jingle insertion or later re-transmission,” Mayah said.

Sixteen coding algorithms are available in the family including G.711/G.722 and MPEG Layer 2/Layer 3 as well as MPEG-4 HE AACv2 and AAC ELD. The line offers support of linear (PCM) audio, AES3 over IP as well as optional apt-X/Eapt-X range at ISDN or IP.

The codecs provide line inputs and outputs for mono or stereo signal, as well as AES/EBU in/out including ancillary data transmission. External devices can be controlled remotely via Opto In / Relay Out interface.

An optional redundant PSU powers up to eight units. “With the efficient management and monitoring software based on standards-based SNMP implementation C11 is ideally suitable for any audio contribution and distribution applications including n+1, 1+1 or n+m redundancy schemes.” EuroMedia Services offers a NetMon management system for the C11 codec family and other Mayah devices.
