LOUDNESS AUDIO METERING Keeping one eye on the loudness levels in a mix can often be a stressful experience, but it doesn’t have to be, as the metering tools in this tech focus show.

RTW Smart Series The Smart range adds extra functions, facilities and flexibility to the meters in the TM3 series and the dual-stereo TMR7. The ultra-compact TM3S is a six-channel meter offering moving coil emulation of broadcast PPMs and loudness scales. The four-channel TMR7S has two AES I/O, a full range of loudness measurement tools and a 7in screen. The TM3-3GS features 16 audio channels of 3G-SDI with a maximum of eight channels displayed at once, offering DPP-compliant loudness measurement, a 16-channel 3G-SDI de-embedder and a monitoring controller with onscreen fader. Touchscreen and flexible user interface enables the selection of presets quickly with just a finger swipe „ Timecode reader on TM3S and TM3-3GS models „Loudness conforms to all relevant international standards: EBU R128, ITU-R BS.1770-3/1771-1, ATSC A/85, ARIB
