TM3 Smart

Firmware version 4-00 for TM3 Smart released: This service release includes improvements and expansions of existing instruments and is available for download in "Audio Monitors/TM3 Smart" section at members area (Manuals & Software).

A TM3 for digital 6-channel operation with full feature set

The compact TouchMonitor TM3 Smart comes with a capacitive 4.3“ touch screen and intuitive preset control at an affordable price. With its feature list, it is the ideal out-of-the box solution for editorial offices, edit suites, small control rooms, and all applications with the need of easy readable loudness-compliant level control.

The Unit
TM3 Smart consists of a display unit for vertical or horizontal use and a remote interface box. It handles analog or digital stereo signals and digital 6-channel signals. TM3 Smart‘s flexible user interface allows the selection of presets quickly and simply with just a finger swipe. 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.

The Devicer Software
When it comes to configuring local presets using the Devicer DC1 software application (Windows® and Mac OS X® compatible), the TM3 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 Smart as required. Devicer DC1 is available for free in the Audio Monitors/TM3 Smart section of members area (Manuals & Software).

The Instruments
Besides PPM and True Peak instruments, the TM3 Smart features comprehensive loudness measuring features conforming to all relevant international standards (EBU R128, ITU-R BS.1770-3/1771-1, 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). And with the Timecode reader instrument a timecode from an external analog or digital source can be decoded and dipslayed.

For existing units the firmware is available for download. See the Audio Monitors/TouchMonitor TM3 Smart section of members area (Manuals & Software).
