Frequency Response Plots of CAT Controllers

 

Test Procedure
Figure 1 shows the test set-up used. A constant voltage of 200mv RMS was maintained from the waveform generator and applied to the receiver #1 input of each controller across all frequencies. The receiver level was adjusted for a internal audio bus level of 200mv. The output level (TX#1) was adjusted for a 0dB reading at 1000Hz on the distortion analyzer as a reference point. Readings were then plotted between 100Hz and 10KHz (see charts below for each controller) for each controller. Distortion measurements were noted and recorded at 100, 500, 1,000, 5,000, and 10,000 Hertz. Units under test were pulled randomly from finish-goods stock.
