SA400 Frequency Response versus Load Resistance
The graph above shows the frequency response of the SA400 into various load
Impedances.
The Amplifier has been optimised for a load Impedance of approximately 5.4 Ohms,
which will give a flat frequency response to over 100kHz, while still allowing High
Power delivery into 2 Ohms should your particular loudspeakers dip this low.
The frequency response with load Impedances from 3 Ohms to 10 Ohms is within +/-
1dB to over 25kHz.
The graph also shows the loss in output level due to the Output Impedance of the SA400
with the various Load Impedances, which is a direct measure of the Damping factor.
