The RTW SW20002 Loudness and SPL Display Module is designed for professional audio applications.
The RTW SW20002 Loudness and SPL Display Module is designed for professional audio applications. It features multiple display modes including bargraphs for individual channels and summation metrics. The module supports various loudness standards such as EBU R128, ITU BS.1771, ATSC A/85, ARIB OP-59, and AGCOM. It includes numerical displays for M, S, I values and other metrics like LRA, TPmax, Mmax, and Smax. The scale options include EBU+9, EBU+18, EBU+9a, EBU+18a, EBU0, ITU+9, ITU0, ATSC0, and ATSC0a.
The module also features a K filter according to ITU BS.1770. It allows adjustable target levels from -10 to -30 LUFS. Time and gate settings include momentary and short integration times with adjustable window periods. Leveling adjustments are available for summation values, with options for 0.0 dB, +1.5 dB, and Off. The module includes loudness test time control with start and stop functions. It also features a loudness range instrument (LRA) with graphical displays and adjustable range settings.
The SPL meter mode includes bargraphs for individual channels and summation metrics with adjustable reference points and weighting options.
