Optimal Audio Zone controllers support digital signal processing (DSP) for the full range of Optimal Audio and some Martin Audio loudspeakers. See WebApp - Line and Amplifier Output Processing for more information.
The following settings should be used as a reference point if you are using 3rd party processing or amplification.
Please note that amplifiers can vary greatly in gain, making it impossible to have a standard limiter setting. When using amplifiers or processors from other manufacturers it is strongly recommended that the appropriate limiter settings are calculated and applied to protect your loudspeakers from damage.
