Knowing the source impedance is very important because the
output gain is calibrated for a matched impedance. A
mismatched load impedance may affect output level accuracy.
For example, for a configured gain of 10, and properly
terminated signals at the input and output connectors (say 50W
each), an input of 2Vp-p will generate an output of 20Vp-p. On
the other hand, if the load impedance increases by a large
factor, the output amplitude increases due to the mismatched
load.
40Vp-p is the maximum amplitude level this amplifier can
produce into high impedance loads. 20Vp-p is the maximum for
loads of 50W, 75W, or 600W
Applying the output signal on inductive or
capacitive loads may damage the amplifier.
