SRM V-Class, SRT - Transparent system protection

TRANSPARENT SYSTEM PROTECTION

Other loudspeakers feature some sort of protection and limiting to help them squeeze a dB or two out of the speaker. This is almost always at the expense of sound quality and is commonly experienced as diminished bass response and the "pumping" sound of the internal limiter having a bad day.

When operating at very high levels (ears beware), the processor-controlled system monitoring analyzes the audio signal and identifies the problem areas, then dynamically applies multi-band compression to those specific frequencies rather than lowering the overall output. This keeps your levels where you want them and maintains the sound quality you expect.
