The OC-12 is AUDIOPLEX TECHNOLOGY 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.
