Linear Acoustic Demonstrates UpdatesFor MT2000 at BroadcastAsia2016
“The Linear Acoustic MT2000 Multichannel Bitstream Analyzer is a feature-packed tool for PCM and Dolby® encoded audio analysis and generation,” says Tim Carroll, Linear Acoustic founder and Telos Alliance CTO. “It is an efficient tool for end-to-end system testing and is ideal as a modern, advanced replacement for the venerable, but long discontinued Dolby DM100.”
This portable diagnostic tool identifies input signal type, including sample rate, video format and frame rate, as well as error detection at the bitstream and AES3 layers. It supports two-channel and multichannel PCM, plus Dolby Digital, Dolby Digital Plus and Dolby E decoding, monitoring, and analysis. The new software update offers a streamlined menu structure, the ability to view 16 channels of audio at once, automatic detection of input signal type, and (optional) SNMP capability. In addition, the MT2000 can also analyze SMPTE 337 formatting, measure Dolby E guard band and line position, and display all the metadata contained in a Dolby encoded bitstream. In support of ATSC A/85 (CALM) and EBU R128 recommendations, it also includes comprehensive ITU-R BS.1770-1/2/3 loudness measurement capabilities with user selectable Dolby Dialog Intelligence.
A bright OLED display provides channel signal levels and loudness, as well as status updates at a glance, while a combination jog wheel and navigation joystick provides complete control. In addition to viewing the characteristics of a signal from the analyzer’s display, engineers can utilize the unit’s built-in speaker or headphone output to listen to the audio on the spot and verify composition and quality of the metered audio signals.
The MT2000 is able to output test signals in both PCM- and Dolby-coded formats, and can output test signals simultaneously on all outputs, even while receiving and decoding an input signal. When generating two-channel PCM tone signals, it allows independently adjustable frequency and level on each channel. It also offers an extensive set of Dolby Digital, Dolby Digital Plus and Dolby E test bitstreams, which are stored internally. The unit also allows for the generation of SDI video, measurement of A/V synchronization (lip sync) and audio latency.
Signal I/O includes HD/SD-SDI, AES, MADI and TOSLINK®. Additional options include DVB-ASI and HDMI inputs. Power is supplied by an internal NiMH battery or an included external DC power supply. The MT2000 is designed and built in the USA, and is backed with a two-year warranty and the world-class support and expertise of Linear Acoustic.
