OWI User Manual: Model AMP-HD2SIC5 / AMP-HD2SIC6 Speaker Amplifier

Introduction

The OWI AMP-HD2SIC5/6 is a three source integratable self powered speaker/amplifier. This speaker can drive up
three additional 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-HD2SIC5/6 include:
Three (3) audio inputs: Stereo 3.5 Mini Jack Line Input, Balanced Line Input, proprietary Cat 5 input for OWI
Products only
Input # 1 Stereo 3.5 Mini Jack Line Input - The JACK LINE IN accepts unbalanced input via 3.5 mini jack. The stereo
channels are summed together. This input is muted when the Priority Override is in use.
Input # 2 Balanced Line Input - The LINE IN inputs accepts a balanced input via a Phoenix style screw terminal plug.
Input # 2 has the Priority Override Feature connected to it. - The Priority input accepts balanced input levels 1
volt (approximately line level) audio and Speaker level at 1 watt or less. Audio on the Priority input suspends audio
on the 3.5 mini jack and Cat 5 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.
Input # 3 Cat 5 input - Proprietary Cat 5 input for OWI Products only. Use only with OWI MC4. Future models
will work with the OWI AMPSTVCW volume control.
Priority Override Paging (POP) – The POP controls are the POP Trigger level and the POP Volume level
POP Volume Level – The POP Volume level is the level at which the speaker will play the POP Message. This
level can be set from Zero to MAX
POP Trigger Level – Adjust this by rotating it from more to less sensitive. If this is too low it will not trigger the
controller to switch. If it is set too high it will constantly stay on and not go back to the needed setting.
Switches
POP / ALL SOURCES MIXED SWITCH – When the amplifier is going to be used in a Priority Override mode
place the switch to the Priority Override
Line Level/Speaker Level Switch – This is for the Priority Override input #2
Balanced Line Level Output
A nominal 0dB level, balanced output is available at LINE OUT. The source of this output is a balanced Line Output via
a Phoenix style screw terminal plug.
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.
