Linear Acoustic(R) Announces LA-5280

Professional Audio Codec

LANCASTER, Pa. -- April 16, 2012 -- The Linear Acoustic(R) LA-5280 is the next-generation stand-alone platform for encoding and decoding Dolby(R) bitstreams and metadata.

The standard LA-5280 will decode Dolby Digital (AC-3), Dolby Digital Plus, Dolby E, HE-AAC (v1 and v2), and MPEG-1 Layer II audio and provide metadata and downmix emulation. It also features an ITU-BS1770 loudness meter with Dolby Dialogue Intelligence(TM). Input and output signal levels plus codec and metadata status are displayed alongside measured loudness for easy verification.

The Infrastructure Encoder version adds eight-channel Dolby E encoding via software key while the Transmission Encoder version adds Dolby Digital (AC-3), Dolby Digital Plus, and HE-AAC encoding via a factory- or field-installed module.

"Being involved with the creation of the original Dolby 'DP' series of products was exciting," said Tim Carroll, President and Founder of Linear Acoustic, "and producing the all-in-one next-generation version of these products is a once-in-a-lifetime honor."

Eight-channel AES I/O with reference input, 3GHz HD/SD-SDI I/O with compensating video delay, stereo analog I/O, GPI/O for alarms, and control and redundant power supplies are standard. SNMP and a remotely controlled eight-channel balanced analog monitor output are optional.
