Setting New Standards: TouchMonitor TM9

Intuitive and flexible audio metering, freely configurable, easy-to-use GUI, 9″ touch screen. A wide range of audio interface options enable straightforward integration in any system. Software licence modules can be ordered with the meter or easily purchased and activated later. These modules offer a wide range of flexible functionality and aesthetic layout options.

The new level

The all-new audio metering units of the TouchMonitor range is RTW‘s answer to growing requirements in today‘s production, post-production, and broadcast world. Equipped with high-grade 7“ or 9“ touch screens and an easy-to-use GUI, TouchMonitor enters a new level of professional audio metering in terms of precision, performance, efficiency and flexibility.

Simple and flexible

The graphical user interface used in the TouchMonitor TM9 is controlled simply by using your finger or a mouse. Instruments can be scaled, randomly positioned and combined in almost every way for optimized use of available screen space. Even multiple instruments of the same type, assigned to different input channels and configurations, can be displayed simultaneously. Plus, a context-sensitive, on-screen help feature supports the user, allowing him to make setup changes with ease.

Basic software and extensions

The fully scalable, modular software concept allows flexible configuration according to your needs. The 4-channel basic software (4 x Mono, 2 x Stereo, 2 x Mono and 1 x Stereo, Peak Hold, Phase Meter, Global Keyboard, Gain-Reduction) can extensively be expanded by activating optional software licences like Multichannel Mode, Loudness, RTA and others. The current firmware version provides measurements of immersive surround formats. On new devices with appropriate audio interface, these signals can also come from AoIP data streams now.

Optional Software Modules:  

SW20001: Multichannel Mode

This module expands the signal routing to the simultaneous display of more than 4 channels or channel groups and additionally processes 3.1 Surround, 5.0 Surround, 5.1 Surround, 7.1 Surround (Cinema and DD+), and Multichannel (2 to 8 channels in one block, up to 4 blocks with 3G SDI option) formats.

SW20002: Loudness and SPL Display

This module expands the basic 4-channel PPM with Loudness measuring functions as described in current guidelines (EBU R128, ITU-R BS.1770-4/1771-1, ATSC A/85, ARIB, OP-59, AGCOM, CALM, LEQ(M), TASA, SAWA), and the LRA instrument for the graphical display of the Loudness Range. A customer-specific mode allows the user to modify parameters. In addition, the module provides the SPL display mode with various weighting filters and integration times as well as reference level adjust to calculate an SPL value from an electrical signal.

For signals with more than four channels software module SW20001 is required.

SW20003: RTA – Real Time Analyzer

This module provides in 1/3-octave, 1/6-octave, or 1/12-octave mode a spectral distribution display for single channels, channel pairs or groups plus HP HF band.

For signals with more than four channels software module SW20001 is required.

SW20004: SSA – Surround Sound Analyzer

— Precondition: Software module SW20002 is already installed! —

At Audio Monitors/TouchMonitor TM7 – Manuals section of the download area (Manuals & Software) you may find a tutorial.

The module also includes the Loudness Chart instrument for displaying and analysing the course of a loudness measurement directly on TM7’s display.

SW20015: ISA – Immersive Sound Analyzer

— Precondition: Software modules SW20001, SW20002 and SW20004 are already installed! —

This module combines the functionality of two Surround Sound Analysers and visualizes the interaction of all relevant technical and subjective parameters of immersive surround signals in an intuitive way. Not only levels (loudness or sound pressure) and correlation of the channels in the layers of the format, but also the relationship between the layers like position and height of the signal and the subjective perceived spatial focal point are displayed. Additionally, the overall Loudness across the layers can be measured.
