TM3-3G Smart

Professional Loudness, True Peak and PPM metering for 3G-SDI audio: TM3-3G Smart

4.3" Desktop TouchMonitor for metering, deembedding and monitoring of 3G-SDI audio signals

The compact TM3-3G Smart with full feature set comes with a capacitive 4.3" touch screen and is a versatile out-of-the-box solution for metering, deembedding and monitoring of 3G-SDI audio signals. With its integrated 3G-SDI deembedder interface, TM3-3G Smart displays level and loudness of any eight 3G-SDI audio channels, which can also be monitored via headphone. Independently from this, up to 16 SDI audio signals can be sent to eight AES3 outputs. The contained factory presets present a cross-section of the applications, audio connections and standards and allow you to start working right out of the box.

  • Easy to read display unit for horizontal or vertical use and remote 3G-SDI interface box
  • Display of up to 8 and output of up to 16 channels of a 3G-SDI signal
  • Quick and easy selection of presets with a finger swipe

The Displays

Besides PPM and True Peak instruments, the TM3-3G Smart features comprehensive loudness measuring features conforming to all relevant international standards (EBU R128, ITU-R BS.1770-4/1771-1, ATSC A/85, ARIB, OP-59, AGCOM, CALM Act). Loudness instruments include single-channel and summing bargraphs, loudness range, loudness chart (TP, M, S, or I value over time), and numerical displays. Moving Coil instruments display stereo signals with different scales and modes (PPM, VU, Loudness, BBC). With the Monitoring instrument an onscreen level fader is available. And with the Timecode reader instrument an external or SDI timecode can be decoded and dipslayed.

Model Versions

The TouchMonitor TM3-3G Smart is economical in space due to its division into display unit and interface box. The remote display unit in the desktop housing can be placed almost anywhere, the interface box under the table or in the console. For installation in front panels, TM3-3G Smart can be delivered with a display unit in a mounting frame.

    Dimensions: 82.5 x 138 x 50 mm (W x H x D)
  • Fixed cable (approx. 2 m)
  • 3G-SDI Interface box with audio I/O, USB, GPIO, low voltage connector for power supply
    Dimensions: 146 x 27 x 85 mm (W x H x D)
  • Power supply

  • Power supply

Configuration with Devicer Software

When it comes to configuring local presets using the Devicer DC1 software application (Windows® and Mac OS X® compatible), the TM3-3G Smart‘s power and flexibility really shines. Existing presets easily can be personalized and adapted to individual needs. Furthermore, Devicer DC1 allows to create several configuration sets with different presets, which may be uploaded to TM3-3G Smart as required. Devicer DC1 is available for free in the download area (Manuals & Software).


TM3-3G Smart can be rack-mounted into 19" environments, using the simultaneously ordered TM3-2U option and the 19"/2U mounting frame.



Option to be ordered simultaneously with TM3-3GS for mounting TM3 devices into rack frame TM3-MA2U or into other appropriate mechanical environments. A display with mounting frame, mounting material, and an USB extension cable is part of the TM3 delivery instead of the display unit with desktop frame. A later replace of the table-top display is not possible.


19“/2U rack carrier/mounting frame to be fitted with up to two TM3 series units which must feature the TM3-2U option. Part of delivery is a blank panel to cover an unused cutout.
