Bose Pow Configuration Utility User Guide
Limiter
The
Limiter
section enables you to specify both peak and RMS voltage limiting for loudspeaker driver
protection.
Note:
Unless stated otherwise, the following Limiter settings are configurable only when the
Low Z
setting
is selected and the
Speaker EQ
setting is
Flat
or
Custom
. When you select a Bose loudspeaker, the
Lim-
iter
settings are specific to that loudspeaker and are visible but cannot be adjusted.
l
Threshold (V):
Allows you to set limits on the final output-level loudspeaker protection. Click the up
and down arrows or type directly in the text box(es) to specify:
-
VPeak:
Determines the maximum signal level allowed to pass through the signal processing
block. Input signal levels above the threshold will be reduced (or hard-limited) to the VPeak
threshold value.
-
VRMS:
Determines the maximum continuous RMS signal level allowed to pass unaltered through
the signal processing block. Input signal levels above the threshold level will be reduced to the
RMS threshold value.
l
Attack (ms):
Allows you to specify (in milliseconds) how quickly the signal is limited after it exceeds
the threshold.
-
VPeak:
This setting is not configurable.
-
VRMS:
Click the up and down arrows or type directly in the text box to specify the amount of time
an RMS signal must exceed the RMS threshold level before the gain of the signal is reduced.
l
Release (ms):
Allows you to specify (in milliseconds) the amount of time it takes to stop limiting the
signal after it goes below the threshold.
-
VPeak:
This setting is not configurable.
-
VRMS:
Click the up and down arrows or type directly in the text box to specify the amount of time
the input signal continues to be reduced after the detection signal drops below the RMS
threshold setting.
Dynamic EQ
Click the
Dynamic EQ
toggle to enable dynamic equalization for the selected loudspeaker. Dynamic EQ
monitors the low-frequency output of select loudspeakers and compensates for a perceived loss of bass
response at low listening levels. After enabling Dynamic EQ, you must calibrate the signal to set the
threshold level.
To calibrate the signal for Dynamic EQ:
1. Click
Calibrate
.
Notes:
l
The
Calibrate
button becomes active when Dynamic EQ is enabled via the
Dynamic EQ
toggle.
l
As a best practice, place yourself in the typical listening position for the output you are cal-
ibrating.
