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