Limiting

 

 

 

Description

This display allows you to adjust limiting parameters that allow for loudspeaker driver protection for each output channel.

 

 

Available Controls

To access Limiting, use the rotary encoder dial from the DSP menu to highlight, then press to select.

 

Navigation Soft Key: Back to DSP menu.

 

Menu Soft Key #5: Enables the selection of the output channel (or output groupings) using the rotary encoder dial.

 

Menu Soft Key #1: Enables the selection of a peak voltage value, which corresponds to the maximum voltage that may be applied to the driver

 

without causing over-excursion. Use the rotary encoder to adjust the selected parameter.

 

Menu Soft Key #2: Enables the selection of an RMS voltage threshold value, which works in conjunction with the subsequent attack and release

 

values. The RMS voltage setting corresponds to the long-term power handling capability of the loudspeaker. Use the rotary encoder to adjust the

 

selected parameter.

 

Menu Soft Key #3: Enables the selection of attack time, in milliseconds, related to the RMS limiter. Use the rotary encoder to adjust the selected

 

parameter.

 

Menu Soft Key #4: Enables the selection of release time, in milliseconds, related to the RMS limiter. Use the rotary encoder to adjust the selected

 

parameter.

 

 

Options

PEAK: 0.5 to 200 Volts (dependant on output mode), 0.5 V increments

 

RMS: 0.5 to 100 Volts (dependant on output mode), 0.5 V increments

 

ATTACK: From 500 to 10,000 milliseconds

 

RELEASE: From 500 to 10,000 milliseconds

 

 

Notes

Values are automatically applied for Bose® loudspeakers set in MAIN MENU < DSP < SPEAKER PRESETS.

 

For non-Bose loudspeakers, refer to manufacturer technical specifications for information to properly configure the limiter.

 

See “Setting the Limiting Function for use with 3rd Party Loudspeakers” on page 33 for further details.
