Product Details
Next Generation PCM and Dolby® Encoded Audio Generation and Analysis. The Linear Acoustic MT2000 Multichannel Bitstream Analyzer is an efficient tool for end-to-end system testing and is the ideal next generation replacement for the original Dolby® DM100.

The Linear Acoustic MT2000 Bitstream Analyzer is a portable, handheld diagnostic tool that can monitor and generate Dolby Digital, Dolby Digital Plus, Dolby E, and PCM bitstreams. With its built-in test-signal generator, the MT2000 allows audio system integrators and service engineers to quickly monitor and check the integrity and composition of Dolby encoded and PCM signals routed through production, broadcast, cable, and satellite facilities, or even a home theater system.

The Linear Acoustic MT2000 accepts signals via AES, TOSLINK™ Optical, HD/SD-SDI, DVB-ASI, and MADI I/O plus HDMI in. The unit identifies the format of the selected input signal and activates the appropriate built-in decoder. Pass-through mode permits modification of the AES channel status bits of the input signal before passing it to the outputs. Monitoring capabilities include error detection at the AES3 layer and within the coded audio layers, including SMPTE 337 formatting information and Dolby E guard band position.

 

FEATURES

  • ITU-R BS.1770-1/2/3 loudness metering

  • Built-in test-signal generator

  • Accepts signals via AES, TOSLINK optical, 3GHz SDI, or HDMI connectors

  • Outputs Dolby Digital/Plus/E and PCM bitstreams

  • Bright OLED display

  • Built-in processed monitor speaker

  • Powered by a replaceable internal NiMH rechargeable battery pack or from its DC power port via included universal power supply

 

IN DEPTH

The MT2000 accepts signals via MADI/AES, TOSLINK™ optical, 3GHz SDI, and HDMI connectors. The unit identifies the format of the selected input signal and activates the appropriate built-in decoder. Passthrough mode permits modification of the AES channel status bits of the input signal before passing it to the outputs. Monitoring capabilities include error detection at the AES3 layer and within the coded audio
layers, including SMPTE 337 formatting information and Dolby E guard band position.

In addition to displaying audio signal statistics and metadata, the MT2000 includes ITU-R BS.1770-1/2/3 loudness measurement with selectable Dolby Dialogue Intelligence™ to support ATSC A/85 and EBU R128. Logging can be provided via the USB connector and/or via SNMP over Ethernet.

An extensive set of useful Dolby Digital, Dolby Digital Plus, and Dolby E test bitstreams is stored internally, and users can modify the set in the field via software download. The MT2000 can generate the selected bitstreams simultaneously on all output connectors, even while receiving and decoding an input signal. The MT2000 is also capable of generating two-channel PCM signals. In this mode, the user can select the output waveform type (white noise, pink noise, sine, square), amplitude, and frequency. Test signals and analysis are also provided for latency and basic lip sync.

Signals are provided simultaneously via the MADI/AES and TOSLINK optical outputs and can be reembedded into any of the SDI pairs. Output can be the original input signal, a multichannel PCM decoded version of the input signal, test signals, or, in the case of the SDI output, a combination of all of these. Inputs can be used as sources for embedding even if not used for decoding thus channel shuffling can be easily accomplished.
