Loudness in Radio Broadcasting – Fully Equipped: TMR7 Smart
4-Channel Metering Solution for Broadcast Environments
PPM, True Peak, Loudness (ITU BS.1770-3/1771-1, ATSC A/85, EBU R128, ARIB, OP-59, AGCOM, CALM Act, LEQ(M), TASA, SAWA), LRA, dual audio vectorscope, moving-coil instruments, RTA, correlation, and chart: The TMR7 Smart 4-channel solution featuring 7“ touchscreen and the unique TouchMonitor operating concept integrates all metering options required in radio broadcasting to an out-of-the-box solution made to measure. Two AES3 digital inputs allow for parallel monitoring of the on-air signal and a PFL source.
The hardware and software of the TMR7 Smart are perfectly adjusted to radio-broadcast requirements. The technological basis of the new unit is the TM7 TouchMonitor with its flexible modular configuration. Available as desktop, fitted, or OEM unit, the TM7 covers all applications in professional audio metering.
Thanks to its versatile interfaces, the TMR7 Smart makes integration into any studio environment a breeze. The four audio inputs provided by the two AES3 XLR ports are flexibly configurable for mono, stereo, or multichannel sources, providing separate instruments for each source. Plus, the GPIO interface for overall control, and the Ethernet port offer even more functionality.
Simple but Flexible
The intuitive operating concept of the TouchMonitor range offers maximum flexibility. Freely scalable instruments can be moved to any position on the graphical surface, allowing you to personalize the entire screen area. Views, scaling, and metering standards are separately definable for each signal source. In addition, the convenient on-screen help function supports you during the setup whenever needed.
Update 6-01 expands basic software and instruments
In Firmware version 6-01, the RTA provides a 1/12-octave mode, Cinema Loudness standards (LEQ(M), TASA, SAWA) have been implemented, and the Audio Vectorscope instrument allows up to 4 instances. The output routing can individually be adjusted for each preset, all presets can be exported or imported at the same time. Further details can be found in the Release Notes (included in the update package), or in the data sheet.
For existing units the firmware is available for download. See the Audio Monitors/TouchMonitor TMR7 section of members area (Manuals & Software).
