Setting the Limiting Function for use with 3rd Party Loudspeakers

The Limiting function allows you to restrict, per channel, the maximum signal level to the loudspeaker. Here are some simplified steps to aid in setting the limiter function.

1.Locate the technical data specification sheet for the 3rd party loudspeaker.

2.Using Figure 14 shown below, configure the amplifier outputs (MAIN MENU < CONFIG < Output Config) to drive the loudspeaker at or beyond the rated power of the loudspeaker indicated in the loudspeaker’s data specification sheet.

3.Select the proper EQ (flat or custom EQ for non-Bose loudspeakers) from MAIN MENU < DSP < Speaker Presets.

4.Using the manufacturer’s loudspeaker specification sheet, find the RMS Voltage for the loudspeaker, or calculate based on the continuous power rating using RMS Voltage = Square Root (rated power of the loudspeaker x loudspeaker impedance).

5.In the MAIN MENU < DSP < Limiting menu, select the appropriate output channel and set the RMS voltage to the loudspeaker’s RMS voltage.

6.Set the Peak value to 2 times the RMS voltage.

7.Reference loudspeaker data specifications or consult with loudspeaker manufacturer to obtain optimal settings for Attack and Release parameters.
