What is an Amplifier?
An amplifier by definition is a voltage generating device,
recreating the signal which is input to it identically but with
increased volume. It will be connected to a reactive load
(the speaker). The impedance of this load and phase of
the signal passing through the load will vary, dependent
upon the frequency of the input signal (music).
Therefore, a perfect amplifier will be able to maintain the
same output voltage regardless of load characteristics
and will not alter the signal it is reproducing. A perfect
amplifier when measured by the AudioGraph PowerCube
would present data that forms a perfect cube. Unfortu-
nately, amplifiers are not perfect. The laws of physics
generally prevent it. A great amplifier is about the best
one can hope to attain.
As you can see by the PowerCube and as you will
experience by listening, your Punch amplifier is a GREAT
AMPLIFIER!
