Chapter 3 Balancing and Setup
2
Measure the signal level at the following frequencies:
The lowest frequency specified in the system design
The highest frequency specified in the system design
3
Compare the measured levels to the design input levels on the system design print.
Note: Add 20 dB to the measured levels to find the true levels. The test point
Note: Add 20 dB to the measured levels to find the true levels. The test point
attenuates input signals by 20 dB.
4
Are measured levels within the desired limits?
If yes, proceed to step 5.
If no, or if no signals are present, find the problem before proceeding. You
cannot balance the amplifier without the proper input signals.
5
Remove the test point adapter from the forward input test point, leaving other
equipment connectors intact.
