Loudness Simplified: Professional Loudness, True Peak and PPM metering for 3G SDI audio with optional 16-channel deembedder outputs and monitor controller

The TM3-3G Smart with full feature set is a compact and versatile out-of-the-box solution for metering, deembedding and monitoring of 3G-SDI audio signals using a 4.3“ touch screen for vertical or horizontal use. The TM3-3G Smart‘s flexible user interface allows for quick and simple preset selection as well as setting the monitoring level.

The Unit
The compact TM3-3G Smart consists of a display unit for vertical or horizontal use and a remote interface box. With its integrated 3G-SDI deembedder interface, the TM3-3G displays level and loudness of any eight 3G-SDI audio channels. Independently from this, up to 16 SDI audio signals can be sent to eight AES3 outputs. TM3-3G Smart‘s flexible user interface allows the selection of presets quickly and simply with just a finger swipe. The contained comprehensive set of 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
Presets can be configured in detail using the Devicer DC1 for Mac OS X® or Windows®. The Devicer’s GUI lets you select, configure and position the instruments you need in a convenient way. The screen layout can be previewed any time so that you always see how your preset will look like on the TM3-3G Smart. Furthermore, Devicer DC1 allows to create several configuration sets with different presets, which may be uploaded to TM3-3G Smart as required. Devicer DC1 for TM3-3G Smart will be available for free in the Audio Monitors/TM3-3G Smart section of the member area (Manuals & Software).

The Instruments
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.1770-3/1771-1, 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). 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.

With the integrated Smart software package, TM3-3G Smart (TM3-3GS) is fully equipped. It provides the wide range of RTW‘s approved loudness and audio metering tools to meet the demands of a wide variety of applications. Beside the signal processing and the control functions this software includes the following instruments and functions:

PPM and TruePeak meter for up to 8 channels with comprehensive set of digital scales, Peak Hold, Peak Memory, Over indicator, numerical display, additional Loudness bargraphs switchable. Additional control keys for positioning on the display.

Moving Coil
2-channel stereo needle instruments with PPM display (British), VU display, Loudness display, and combined PPM and Loudness display (BBC mode). Additional control keys for positioning on the display.

Loudness Sum
Loudness Sum instrument for displaying the summed loudness values M, S, and I of a loudness measurement acc. to EBU R128,
ITU BS.1770-3/1771-1, ARIB, ATSC A/85, OP-59, AGCOM, CALM Act or customer specific on bargraphs, or an SPL meter. Additional control keys for positioning on the display.

Loud. Num.
Loudness Numeric instrument for the numerical display of all relevant values of a Loudness measurement: M, S, I, LRA, TPmax, Mmax, Smax, I-time. Additional control keys for positioning on the display.

Loudness Range instrument with MagicLRA mode for a graphical representation of loudness variances with additional display of the I value. Adjustable ranges with different colors. Additional control keys for positioning on the display.

Loudness Chart
Loudness Chart instrument for displaying and analyzing the course over time of one selectable value of a loudness measurement directly on the display. Additional control keys for positioning on the display.

The Dialnorm instrument is used to calculate and to show numerical Dialnorm values (w/o speech intelligence) from digital surround signals. Additional control keys for positioning on the display.

Correlator (available in 2-channel mode)
Stereo Correlator for displaying the phase relationship between the two channels of a stereo signal and thus its mono compatibility. Additional control keys for positioning on the display.

Timecode Reader
The Timecode Reader instrument is used to decode and to display the SDI timecode or an LTC timecode of an external analog source for the use with Loudness applications.

Deembedded Out
Matrix for the routing of 16 deembedded audio channels to 8 AES3 outputs via 25-pin Sub-D.

Monitoring instrument with control function for enabling the monitoring of displayed audio signals. The instrument features monitor level control with onscreen level fader (can be calibrated), DIM and Mute function, and internal Downmix for multichannel monitoring. Audio output of monitoring signals via RCA or 3.5 mm jack (analog).

AES Status
AES Status monitor for displaying various parameters of AES3 digital audio signals in plain text. Additional control keys for positioning on the display.

SDI Interface
Instrument for displaying the status of the 3G/HD/SD-SDI deembedder interface showing the SDI and video format, and a list with the included and available audio signals and audio groups.

Global Keyboard
Global Keyboard with definable on-screen keys for simultaneous control of defined functions in multiple instruments, and for preset recall. It also allows external control vial GP IO interface.
