Amplifier Gain Matching
1.
Connect a digital voltmeter set to AC volts between the positive outputs of the first and the second
amplifier (see Figure 4.15).
2.
Adjust Amp Gain Trim (R210) on the second amplifier for minimum AC voltage (millivolts).
3.
Repeat the process of checking gain between the first amplifier and any additional amplifiers in your
system.
4.
Continue checking and adjusting until the gain of all amplifiers in the system is matching to within
millivolts.
