Input Sensitivity Setting
The Input Sensitivity adjustment is located on the rear panel, to the right of the input RCA jacks. This
feature allows you to select how large of an input signal will result in full power output of the amplifier.
The Input Sensitivity adjustment can be used to “match” the Stereo 160 inputs to your preamplifier
outputs. You can set it so that the preamplifier volume control can be turned all the way up before
clipping occurs in the Stereo 160. This also allows you to connect audio components, such as CD
players, directly to the Stereo 160 without using a preamplifier, if desired.
Most power amplifiers have input sensitivities in the range of 1 to 1.5 volts. If an amplifier has an input
sensitivity of 1 volt, this means that an input signal level of 1 volt will produce the full rated output power
of the amplifier.
The Input Sensitivity on the Stereo 160 can be adjusted as follows:
Set at Normal (12 o’clock) the input sensitivity is approximately 1.5V.
Set at Low (9 o’clock) the input sensitivity is approximately 5.5V.
Set at High (3 o’clock) the input sensitivity is approximately .5V.
Set fully clockwise, the input sensitivity is under .3V.
