13. Override Introduction The OWI AMP1SGRN is a self powered speaker amplifier This unit can drive up to four speakers connected series parallel to have a net impedance of 8 ohms With an included UL Listed Level 5 Energy Star 15 volt 3 5 ampere power supply the amplifier can output 32 watts or 8 watts per speaker in a four speaker hook up Special features of the OWI Model AMP1SGRN include Energy Star Sleep Mode If no audio is present on any input for a nominal factory set delay time of 2 minutes the power amplifier is put into a low power shutdown mode The delay time is settable but for Energy Star rating the maximum time is 30 minutes the factory set time is 2 minutes During sleep mode power consumption of the speaker amplifier is less than one 1 watt The power supply during sleep mode draws a very small power Three audio inputs Normal Auxiliary and Priority Override The Normal input accepts a balanced input via a Phoenix style screw terminal plug A9 or an unbalanced input via minijack A12 The A12 input can be microphone level or line level set by A10 The line level can range from 20dBu to OdBu The microphone level input can be 40dBu The minijack can accept mono or stereo inputs The stereo channels are summed together This audio is adjusted with potentiometer adjacent to Auxiliary Input This input is muted during Priority Override One use of the auxiliary input is for an infrared microphone Priority
