RTW TouchMonitor TM3-Primus Loudness Meter

Professional, Extensive Loudness Metering in an Ultra-compact and Budget-friendly Desktop Meter.

The RTW TM3-Primus Desktop Loudness Meter provides a full set of easy-to-read high quality instruments for multi-functional loudness measurements (analog, digital, via USB) at an entry-level price.

Its USB Hybrid function with RTW USB Connect plug-in allows direct access to and simultaneous monitoring of audio signals from a DAW or an audio application. With the innovative USB hybrid function, metering can be performed right from the DAW via RTW USB Connect software, and the TM3-Primus devices will process and visualize the information without the need for additional wiring or extensive signal routing, and without dropping the standard audio interface.

TM3-Primus is available as table-top device (shown) or in a rack frame for rack-mounting.
