Drukuj stronęThe OC-12 is AUDIOPLEX TECHNOLOGY's latest innovative impedance matching system. It's high
efficiency auto-transformers ensure no significant power loss under any load condition. The OC-12 is
designed to be inserted between the power amplifier and up to 12 stereo speaker pair locations. It incorporates
direct PC board construction to minimize bad wiring connections.
The unit contains two high powered auto-transformers with switch selectable taps for the ultimate in
convenience, allowing maximum power transfer while maintaining a safe load of 4 Ohms or higher regardless
of the number of speakers in use. With the impedance selector switch optimally set there will be a level drop,
but full amplifier output will be available divided equally among the 12 speaker outputs.
The unit is capable of transforming a 1/3 Ohm load to appear as a 4 Ohm load to the amplifier, which is
equivalent to 12-4 Ohm or 24-8 Ohm speakers operating simultaneously. A unique high-pass filter is included
to prevent very low frequency (subsonic) information transferring to the impedance matching system. The high
pass filter reduces sub-audible audio overloading, which causes a transformer impedance drop. This leads to
transformer core saturation and the resulting impedance drop transients caused by excessive low frequency
power input. Removing these undesirable effects permits higher power operation in the main audio spectrum
without amplifier shutdown, even when heavy bass is present. This also assures more consistent operation,
with fewer call backs because of distribution system breakdown.
The OC-12 is available either as a free-standing or rack mountable model.
Following the wiring diagram on the back of this sheet, connect the receiver/amplifier to the INPUT
connector block and the speakers to the OUTPUT connector blocks (note that the INPUT connector block is
green and the OUTPUT connector blocks are black).
