Model AMP-R2SIC5 / AMP-R2SIC6 Speaker Amplifier

Introduction

The OWI AMP-R2SIC5 / AMP-R2SIC6 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 40
watts, or 10 watts per speaker in a four speaker hook-up.
Special features of the OWI Model AMP-R2SIC5 / AMP-R2SIC6 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.
Two (2) audio inputs: Line In and Jack Line In
The LINE IN inputs accepts a balanced input via a Phoenix style screw terminal plug. The JACK
LINE IN accepts unbalanced input via 3.5 mini jack. The mini jack accept stereo inputs. The stereo
channels are summed together. This input is muted during Priority Override.
Priority Override Feature
The Priority input accepts balanced input levels of resistor selected 100 volts audio, 70 volts
audio, 25 volts audio and 1 volt (approximately line level) audio. Audio on the Priority input
suspends audio on the Line In and Jack Line In inputs and switches the speaker amplifier to pass
the Priority audio. After the Priority audio stops, the unit waits before returning to the Line In and
Jack Line In audio input.
Balanced Line Level Output
A nominal 0dB level, balanced output is available at LINE OUT. The source of this output is both
balanced and Jack Line In sources.
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.
