mono from any low impedance audio source such as a compact disc or MP3 player. The input must not exceed the maximum voltage level of 250mV peak, since audio quality can not be guaranteed at such levels. The system must drive two 8-Ohm speakers with a minimum gain of –3dB and 20dB. This is 0.7V/V and 10V/V in terms of amplitude.
