Automatic Saturation Compensation
When the TK-150 transformer is installed in an EVC loudspeaker, it engages EV's patented
Automatic Saturation Compensation (ASC), which preserves low frequency performance while
presenting a stable load to the amplifier - regardless of the number of speakers connected in
parallel. As a result, EVC loudspeakers - including the subwoofers - sound virtually identical,
whether they are used with a transformer or without.

Secure the transformer mounting ears to the four input panel bosses with the four #10
screws (A) provided.
Carefully tighten the screws evenly in an X-cross pattern to avoid warping the plastic input
panel.
Unplug the 8-position jumper connector located at right angle to the 7-pin crossover
header.
Plug in the 8-position wiring harness connector (B) from the transformer to the 8-pin
header in place of the jumper.
Notice the direction of the connector.
Reinstall the input panel in the same orientation it was in before removal.
Do not install backwards.
Apply the new label (supplied) over the input connectors.
Connect the (-) input line to the COM input terminal and the (+) input line to the terminal
corresponding to the desired wattage in either the 70.7V or 100V column.
