[Load Analysis>Launch Load Analysis] - This is the working window for performing a load analysis. The user must
first select an available networked amplifier from the <Analysis-Capable Amplifier> 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 filters 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.
the Sweep Level and Sweep Start Frequency are
properly set for this loudspeaker before running the
test!
Click on <Test Amplifier> 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 finished, 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 amplifier is only useful for learning the pro-
cedure, it provides no meaningful data.

9.2 nX Device Options Menu

Double-click on a nX amplifier in the network tree or on the canvas.
9.2a Flash Reprogram Mode
a new program file (firmware) to the amplifier over the network. Latest firmware updates, if avail-
able, can be found on the Ashly website. When the amplifier is put into flash reprogram mode,
all audio functions are suspended, the power switch LED flashes, and the COM LED remains
lit until flash reprogram is completed. Flash reprogram only appears in the device options menu
when a live device is connected.
9.2b Link Group Configuration
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 amplifiers support up to 16 Link Groups, 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 identification. For further details about linking, see the online help in Protea
