The Linear Acoustic MT2000 accepts signals via AES, TOSLINKTM optical, 3GHz SDI, or HDMI connectors.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.
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 IntelligenceTM to support ATSC A/85 and EBU R128. Logging is 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 bitstream 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 AES and TOSLINK optical outputs and can be re-embedded 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.
A bright yellow OLED display and integrated rotary navigation cluster provide straightforward menu navigation and function adjustment. A standard 1/8-inch stereo headphone jack can be switched to monitor any two decoded channels or a downmix of the whole program. Digitally amplified stereo speakers provide a surprisingly loud output useful for quick checks and for emulating sound systems found in portable devices.
The MT2000 is powered by an internal NiMH rechargeable battery pack or from its DC power port via an included universal power supply. It ships with a soft carrying case and multiple adapters.
