Introduction:
Congratulations on purchasing the Control Center by OWI.
The OWI CONTROL CENTER is a 50-Watt (25 x 2) High Fidelity Amplifier, Mixer and Room Combiner all in a
small package that fits into a double gang box. This high quality durable unit is capable of powering up to 4 speakers
per side for voice, music and paging. The Control Center has 3 independent inputs that can be used for Line or Mic
input. It is projector compatible, RS232 controllable and it comes with a 15V DC power supply.
This product represents very advanced electronics and circuits that in some cases have never been installed into a two
gang box. The three inputs represent the latest designs for Microphone input circuits. The line input circuits also are
instrumentation grade, balanced and differential circuits. They represent complete DC isolation from outside wiring
and high common mode rejection of noise. Input wiring can be as long as 3000 ft.
Mic and Line Inputs
Both the Mic and Line inputs enjoy a very advanced Limiter circuit. It will allow a wide variation in input level or mic
level depending on the speaker holding the microphone close or farther away.
Before starting
We recommend that the power supply be located above the ceiling in an electrical box with a cover. It will fit into a 3
or 4 gang box. The power supply is very special and should not be replaced with an off the shelf 12 volt supply. This is
a 15 volt supply and is designed to deliver full power when combined with the CCRC main board. The power supply
is UL rated and will operate anywhere in the world. The power cord will have to be changed for the appropriate style.
Selection of Mic or Line is done just before installation by moving a red jumper to either the designated Mic or Line
position. Once installed , this jumper is away from prying fingers.
The Amplifier
The amplifier used is the choice of many a Hi Fi installations. Operating at more than 80% efficiency, it is a Class D.
It will generate 25 watts times two. Two separate outputs each can deliver 25 watts into 4 Ohms. In the case of many
speakers operating at 1 or 2 watts, we recommend purchase of the OWI 70 volt 30 watt transformer. You can use of
two of them, one on each output. These two transformers will fit into a three gang electrical box to keep them away
from prying hands.
The Line Out
The Line Output is a fully professional balanced line driver suitable for use in Hotels, Convention Centers, Public
buildings, schools and colleges. It is fully capable of driving long distances of up to 3000 ft. Twisted pair wire with
shield such as Beldon 9451 or equivalent will give excellent results. Line out is factory set to a nominal 1 volt.
Line Out tying the shields
Normally the shield is connected only at the far end. Leave the shield taped back at the originating CCRC. This is most
often the optimum grounding for minimum hum.
