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.
