Vseries panels have a on-board DSP mixer. The mixer allows any local input on the panel like microphones, headsets or external I/O to be routed internally to any local output on the panel like loudspeaker, headsets or external I/O. The DSP allows changes to the mic limiter and compressor These filters are applied to input audio streams to remove extraneous noise from the audio before it is sent to the mixer. There are two types of filter; the “Low Pass” filter and the “High Pass” filter. The Low Pass filter will pass low frequencies and is used to remove high frequency noise such as wind noise while the High Pass filter will pass high frequencies and is used to remove low frequency noise such as machinery. Each filter has four possible settings; off, filter 1, filter 2 and filter 3.1. Off - no noise filtering is done.2. Filter 1 - uses the first noise filtering algorithm.3. Filter 2 - uses the second noise filtering algorithm.4. Filter 3 - uses the third noise filtering algorithm
The filter configuration is shown using a graphic of the frequency against level.
