RTW introduces the DigitalMonitor 10500 digital audio monitor

RTW has introduced the DigitalMonitor 10500, a comprehensive display unit for digital stereo audio signals. It has an AES3 signal input that supports sample rates up to 96kHz and a parallel XLR output for seamless integration in fully digital studio environments. Two multistandard peak meters, a correlator display, an informative AES status monitor and the new ITU-compliant loudness display are all presented on the unit's large TFT display. There is also an output for an optional external VGA display.

A reliable and standardized method for evaluating program loudness is essential for audio and video work to prevent, for example, unpleasant volume jumps between different program segments in radio and TV broadcasts. The DigitalMonitor 10500 now features an integrated loudness measurement (as per ITU BS.1771) for stereo signals, and these loudness measurements can be selected as an alternative to the usual peak meter bar graphs. Presets enable the user to switch between the two modes at any time, and selection of the new mode activates an ITU-compliant scale for the loudness display in the program meter area (formerly the peak meter) calibrated in decibels from -21dB to +9dB.

The display shows two bar graphs for the individual channels and two additional bar graphs — one for the combined loudness of the stereo channels and one for the result of integration over a longer time. This integrated display, featuring a dynamic time window, is not affected by periods of silence because signals below a user-adjustable threshold are ignored.
