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).

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!
