OWI SELF-AMPLIFIED (SINGLE INPUT/ SOURCE) SPEAKER MODULE
AMPIC5 OR AMPIC6
Description:
Having many of the recent most popular installer features, the AMPIC 5/6 power module is made to expressly fit
onto the OWI Model IC5 or IC6 coaxial speaker providing a high fidelity module providing up to 25 watts of Class
AB power right at the speaker. By being within inches of the speaker, the amplifier enjoys maximum damping
control of the speaker since the speaker sees optimum low source impedance for maximum high fidelity
reproduction. By being a dedicated amplifier to this speaker, it is tailored to match the speaker for optimum
response.
Lower Noise Feature, Differential input
The power module has critical features making it a fast and easy install in the field. To reject noise, it has a fully
differential amplifier at its input. Also it provides the same kind of noise suppression a transformer does with
excellent common mode noise rejection.
Single ended sources (unbalanced) such as CD, DVD
Where the source is single ended such as CD player, plus goes to plus and the shield goes to the minus input. If any
noise is observed, place a jumper between minus and ground.
Minimum additional space
The amplifier is molded to fit exactly around the speaker magnet allowing the smallest possible size. It adds barely
an eighth of an inch more depth for those tight installations. For convenience the connectors located under the PCB
are docking and simply unplug allowing convenient wire attachment.
To further enhance it’s ease of installation, each power module has both a second connector for downstream
amplifiers and individual volume controls at each amplifier. If no controls are wished at the speaker, simply turn it
fully clockwise for maximum gain and set levels at the control electronics.
Wiring to down stream power modules using the provided output connector
Wire Plus to Plus, Minus to Minus, but only connect one end of the shield at the second amplifier module. This will
optimize system noise. For third amplifiers etc. follow the same rule; connect all three wires at the farthest module
and don’t connect the shield at the second connector
Wiring the speakers. - The amplifier is capable of delivering power into either 4 or 8 ohms.
1 speaker – direct
2 speakers – Parallel - Since the speaker is 8 ohms, two in parallel work well
4 Speakers – Use series parallel- Wire speaker pairs in series then take the pairs and place them in parallel. This will
provide approximately 6.5 watts per speaker or a maximum of 25 watts. Actually the output power is influenced by
the length the wire is run, and wire gauge.
Power source
Power is provided by a 12 volts AC source. There is no polarity on the power input. Use a minimum of 16-gauge
wire. If the installer is stuck with only DC, it will work too. Either AC or DC power source will work up to 14 volts.
The Power Module AMPIC 5/6 comes with a 12-volt AC power supply optimized for this amplifier.
Wire gauge
For music applications, where one amplifier is powering one more speaker, use a minimum of 16-gauge wire. For
Monday night football bar installations, make the wire gauge as large as possible between speakers.
Low level audio wire runs
Low-level audio needs only 22 gauge twisted pair with shield. Beldon 9451 or equivalent is a popular choice. Being
differential, the low level input can be as long as 3500 feet without concern. If the source is unbalanced, a balancing
preamplifier is recommended for longer runs over 200 ft.
