Parameter	Value	Values
CAL NOISE	ON	ON, OFF
L/R LIMITER	OFF	ON, OFF
L/R LIMIT ADJ	100dB	75 to 115dB
LFE LIMITER	OFF	ON, OFF
LFE LIMIT ADJ	100dB	75 to 115dB

Note:

In cases where the left and right subwoofers have built-in limiter protection, the L/R LIMITER parameter should be set to OFF. In cases where the LFE subwoofer has built-in limiter protection, the LFE LIMITER parameter should be set to OFF.

CAL NOISE (ON, OFF)

CAL NOISE determines whether limiters will be set using an internal or external noise signal. When set to ON, the unit activates the internal calibration noise to set the limiters. When set to OFF, the unit deactivates the internal calibration noise, requiring the use of an audio calibration disc to set the limiters.

L/R LIMITER (ON, OFF)

L/R LIMITER affects the SUBWOOFER L/R outputs, as well as any low-frequency signals redirected to other MAIN AUDIO OUTPUTS. When set to ON, these outputs will be restricted to the limit specified in the L/R LIMIT ADJ parameter. When set to OFF, the output level of these outputs will not be restricted. The L/R LIMITER should be set to OFF when the left and right subwoofers have built- in limiter protection.

L/R LIMIT ADJ (75 to 115dB)

L/R LIMIT ADJ specifies the output level restriction placed on the SUBWOOFER L/R outputs, as well as any low-frequency signals redirected to other MAIN AUDIO OUTPUTS, when the L/R LIMITER parameter is set to ON. Press the right MENU arrow to select this parameter for adjustment. Its setting will automatically change to 75dB. Use the up and down MENU arrows to increase and decrease the setting in 1dB increments. Gradually increase the setting until the subwoofer begins to overload, then reduce the setting until the subwoofer stops overloading. Press the left MENU arrow to accept the setting and exit the parameter.

LFE LIMITER (ON, OFF)

LFE LIMITER affects the LFE output. When set to ON, the output level of the LFE output will be restricted to the limit specified in the LFE LIMIT ADJ parameter. When set to OFF, the output level of the LFE output will not be restricted. The LFE LIMITER should be set to OFF when the LFE subwoofer has built-in limiter protection.

LFE LIMIT ADJ (75 to 115dB)

LFE LIMIT ADJ specifies the output level restriction placed on the LFE output when the LFE LIMITER parameter is set to ON. Press the right MENU arrow to select this parameter for adjustment. Its setting will automatically change to 75dB. Use the up and down MENU arrows to increase and decrease the setting in 1dB increments. Gradually increase the setting until the subwoofer begins to overload, then reduce the setting until the subwoofer stops overloading. Press the left MENU arrow to accept the setting and exit the parameter.
