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.
