RTW TouchMonitor TMR7

The TMR7 is a new addition to RTW’s range of touchscreen-based audio metering and analysis displays. Based on the TM7, it is specifically intended for monitoring of stereo programme material in radio on-air and production studios. It provides the user with all the information necessary to achieve accurate sound level and loudness management. Four channels are provided to permit connection to a desk’s monitor output as well as the main programme feed.

The 7” 16:9  touchscreen is available as either a free-standing desktop display, or a bare chassis version for mounting in custom equipment or furniture. The set of measurement “instruments” it provides is defined by the customer to match the user’s needs. Apart from the basic PPM capability, all instruments are in the form of optional individual software modules, and may either be specified at the time of order, or added at a later date to address new operational requirements.

The standard unit provides a 4-channel PPM with digital scaling (-60 dB to 0 dB/-60 dB to + 3 dB TruePeak, quasi-DIN, quasi-Nordic or quasi-British IIa/IIb) with Peak Hold, phase correlation metering, and a vectorscope display for a graphical representation of stereo components. These functions can be expanded with the addition of three software modules:

• Loudness measurement of all 4 channels, compliant with EBU R128, ITU-R BS.1770-3/1771, ATSC A/85 and ARIB guidelines; includes Loudness Range (LRA) with numerical display of ‘I’ value and ‘MagicLRA’ meter and Loudness measurement of M and S values. SPL measurement with various weighting and filtering options.
• 31-band Real Time spectrum analysis of single channels or pairs.
• Extra scale options for the main PPM (Zoom, SMPTE, NHK, ARD+9, etc.), high-resolution emulation of single- and dual-needle PPMs and VU moving coil meters  meters, a second vectorscope and a second phase meter.

The TMR7’s full colour screen layout is entirely definable by the user; each instrument’s display is a window which may be made active, sized and positioned at will. All instrument controls are accessed by touching the screen; or if preferred, a USB mouse may be used. A VGA output is provided to allow the screen image to be displayed on a larger external monitor. A GPIO port is included to permit external selection of unit configurations, and an Ethernet/LAN port to allow additional software modules to be installed.

The TMR7 is designed to interface directly within a digital broadcast infrastructure and comes with two balanced AES3 digital inputs. Each input has a loopthrough output for the connection of downstream equipment.
