Item: TM3


Loudness Simplified: Professional Loudness, True Peak and PPM metering at an affordable price with easy and flexible preset control.
The compact TouchMonitor TM3 comes with a capacitive 4.3“ touch screen and intuitive preset control at an affordable price. With its feature list, it is the ideal 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 consists of a display unit for vertical or horizontal use and a remote interface box. It handles analog or digital stereo signals (TM3) and digital 6-channel signals (TM3-6CH). TM3‘s flexible user interface allows the selection of up to 10 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‘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 as required. (Devicer DC1 is available for free in the Audio Monitors/TouchMonitor TM3 section of members area (Manuals & Software)). Purchase and activation of software licences can also be managed with the Devicer.
The Instruments.
Besides PPM and True Peak instruments, the TM3 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 and numerical displays.
Update 3.50 available.
Firmware version 3.50 allows the purchase of a software bundle as a licence upgrade for activating all licences and for expanding the completed feature set with the Loudness Chart instrument. When the software bundle has been installed, upcoming instruments and functions can be added via firmware update.
The Loudness Chart instrument is used to display the progress of a measurement (TP, M, S, or I value over time) as a line or colored area under curve on a coordinate system with selectable time range. Additionally, the tolerance range can be displayed as a kind of corridor. A dynamic line shows the position of the Relative Gate in relation to the I value, and an additional bargraph for the display of the current I loudness value can be selected.
For existing units the firmware is available for download at the RTW web site.
