[Load Analysis>Launch Load Analysis] - This is the working window for performing a load analysis. The user must
rst select an available networked amplier from the <Analysis-Capable Amplier> device tree, then select the output channel
to test, then apply the appropriate test settings.
Warning: Do not send low frequency test tones to high
frequency drivers or use excessive sweep level, always be
certain that the swept frequency range and output level is
within the safe operating range of the speaker under test.
Remember that all DSP functions are disabled, including
crossover lters and limiters. A sweep level setting of 1V
will produce a relatively quiet test tone into any speaker,
however load impedance characteristics can change at higher
volume levels, so test accordingly but carefully. Make sure
the Sweep Level and Sweep Start Frequency are
properly set for this loudspeaker before running the
test! Click on <Test Amplier> and a series of tones will
be heard through the loudspeaker under test. The test can be
immediately cancelled by pressing the same button again.
When the test is nished, a plotted curve (yellow) shows
load impedance vs. frequency. Click <Set Ref.> to establish
this curve as a reference (red) baseline, or save the data to
disk for future tests.
Note: Running the load analysis tool when there is no
speaker connected to the amplier is useful for learning about
the procedure, but provides no meaningful data.

9.2 nX Device Options Menu
Double-click on a nX amplier in the Network tree or on the canvas.
9.2a Flash Reprogram Mode - A nX amplier can be ash reprogrammed by
downloading a new program le (rmware) to the amplier over the network. Latest rmware
updates, if available, can be found on the Ashly website. When the amplier is put into ash
reprogram mode, all audio functions are suspended, the power switch LED ashes, and the COM
LED remains lit until ash reprogram is completed. Flash Reprogram only appears in the device
options menu when a live device is connected.
9.2b Link Group Conguration - Link groups allow DSP functions of the same
type to track each other across channels within a device. For example, if two separate EQ
controls on different channels are linked, any change made to either one of the equalizers
will result in an identical change to the other.
nX ampliers support up to 16 Link Groups, and every DSP tool can be assigned to one of these groups. Once assigned to
a group, all similar DSP functions within that group will track parameter changes with each other. More than one type of DSP
function block can be assigned to the same group. Each link group can be assigned a name by the user, and can also be assigned
a color for easy identication. For further details about linking, see the online help in Protea
ne
software.
