low-­‐frequency response, effectively limiting the linear excursion to below the X-­‐max specification of
the driver. To set the limiter up, it is necessary to know the shape of the family of Excursion vs.
Frequency curves of the driver for various drive voltage levels. A curve should then be chosen where
the slope is high where it passes though the specified X-­‐Max value for the driver. The peak voltage
and frequency of this point should then be noted.
The Xmax limiter is usually then set up using just two parameters:
Threshold – the peak voltage of the point arrived at above. This is calibrated at the output of
the amplifier. The Excursion Limiter can be defeated by setting Threshold to the maximum
“Off” value.
Frequency – The frequency at which the above threshold voltage is appropriate.
A further parameter “ Min ” may also be available for more advanced applications. This allows the
increasing limiting action at lower frequencies to level-­‐off below a certain frequency. In most
application, this would be left set to its default value of 5Hz.
Bridge
When an amplifier pair is set to Bridge Mode, it uses two amplifier channels to drive one
loudspeaker with greater power. In this mode, only one set of Output controls is active per pair of
amplifier channels since both of the amplifiers in the pair are driven with the same signals, as
determined by the channel 1 (or channel 3) controls. Bridge settings should be set up
before
recalling Drive Module Presets . Module Preset Recall will see a bridged pair of outputs as a single
channel. Bridge Mode is enabled or disabled in the AMP page for a given odd numbered Output.
When enabled, the Bridge indicator will be illuminated between the bridged channels.
Routing
Outputs can be driven from any DSP input. This routing is the fundamental means by which Drive
Modules are created. Routing should always consume outputs consecutively alphabetically and
numerically. However, non-­‐consecutive Drive Modules may be created using manual routing and
Recalling Components . See the drive module section of this user manual for more information.
Utility Pages
Screen Contrast
The Screen page in the “ UTILITY ” section adjusts the contrast (and optimal viewing angle) of the
screen from 0-­‐100% in 1% increments.
Stereo Linking
Stereo linking is available between DSP Drive Modules A & B and between C & D. Changing a
parameter in either of the stereo linked Drive Modules will change the other linked Drive Module.
Stereo linking is controlled by the
STEREO page in the “ UTILITY ” menu.
Note: Stereo linking will only work when the linked Drive Modules are of equal size.
Current Ethernet IP Address
This may be viewed in the “ IP Curr ” page of the “ UTILITY ” menu. This value cannot be edited.
