What is an Amplifier?
An amplifier by definition is a voltage generating device,
recreating the signal which is input to in an identical but
amplified
form. 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 and amplitude 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 for.
As you can see by the
PowerCube
and as you will
experience by listening, your Punch amplifier is a GREAT
AMPLIFIER!
