FX100 Use Case

Mixing Console Test
FX100 Use Case
A leading manufacturer of mixing consoles was looking for
an Audio test instrument that would significantly reduce
the test time for the final inspection in on the production
line.
The key challenge was to squeeze a wide scope of measurement types with broad specifications as well as operator interactions into a short test sequence.
Thanks to the outstanding performance and flexibility,
NTi Audio’s FX100 Audio analyzer + I/O switcher were selected as the preferred test solution.

The challenge
A high-volume manufacturer of mixing consoles was looking
for an alternative for his current verification procedure in order
to speed up the final check.
The new test procedure should be controlled by a PC and
verify the full functionality of the consoles, i.e. including all
I/O connectors and potentiometers, the monitor output, the
built-in MP3 player etc.

The solution

Highlights
•tOverall test cycle time reduced
from 30 min down to 6 min.
•tVB program controls the test
sequence including manual
interactions and test report
generation.
•tTest sequence includes
reliable detection of rasping
potentiometers.

After a brief analysis of the status quo it became clear that only
a fast measuring instrument in combination with a thoughtout system architecture could meet the requirements without
boosting the system costs.
Consequently, the FX100 Audio analyzer was chosen together
with the OS-0210 output and the IS-1002 input switchers.
Furthermore, NTi Audio programmed a customized Visual Basic
script, based on the FX100 .NET API, which stepwise initiates the required tests, interacts with the operator regarding
manual actions, and creates an extensive test report.
The new test setup successfully reduced the overall cycle
time from approximately 30 minutes down to 6 minutes per
mixing console.
