Introduction 

 
The OWI 

AMP1SGB

 is a self-powered 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 40 watts, or 10 watts per speaker in a four speaker hook-up.  
 

Special features of the OWI Model AMP1SGB include

 

Energy Star Sleep Mode 

 
If  no  audio  is  present  on  any  input  of  the  power  amplifier,  the  amplifier  goes  into  a  low  power 
“shutdown,  or  sleep  mode”  within  30  minutes.   During  sleep  mode,  power  consumption  of  the 
power supply and the amplifier is less than one (1) watt. 

 
One (1) audio input: Line In 

 
The 

LINE IN

 inputs accepts a balanced line level input via a Phoenix style screw terminal plug.  

 

Balanced Line Level Output 

 
A nominal 0dB level, balanced line level output is available at LINE OUT via 3.5 mini jack. 
 

Power Amplifier Features 

 
The power amplifier outputs 2 times 20 watts or 40 watts total into 8 ohms and 15VDC power. The 
class D power amplifier has reduced radiated electromagnetic interference (EMI) due to a special 
feature  of  the  power  amplifier,  operating  in  a  patented  spread  spectrum.  The  power  amplifier 
protects  itself  from  over-temperature,  over-current,  over-voltage  conditions.  The  power  amplifier 
will shut itself down during these conditions. 

 

 
IMPORTANT NOTE!  This amplifier is intended for audio use only! Continuous sine wave drive into a load 
will cause the amplifier to shut itself down when it heats up.
