High Pass Filter Requirements:
!
Caution!
Failure to use the proper high-pass filter may result in damage to the amplifier.
The TK-150 audio transformer is designed to be used with Butterworth 24 dB/octave high-pass
filter inserted in the signal chain at the input to the amplifier. The filter corner frequency
should be set at 50 Hz for full-range models. This filter, in conjunction with the Automatic
Saturation Compensation (ASC) feature, protects the amplifier from damage caused by
transformer saturation at low frequencies and allows any number of transformers to be driven
on the same 70V or 100V line, up to the rated power of the amplifier. At the same time, the
ASC circuit preserves the low-frequency extension of the system by adding incremental
filtering only to the extent required by the current level in the loudspeaker.
Notice!
Each group of four terminals is electrically connected in parallel to the group of four terminals
directly across from it.
The wattages charted in these two columns represent the wattage available from each of the
three transformer taps at the designated voltage.

Caution!
This transformer affects only the loudspeaker to which it is installed.
Improper connection may result in damage to the transformer, successive loudspeakers, the
driving amplifier or any combination of these units.
!
Caution!
When daisy chaining additional systems, connect the wires to the next system only to those
terminals directly opposite the input wires.
Improper connection may result in damage to the transformer, successive loudspeakers, the
driving amplifier or any combination thereof.
Notice!
Tighten all unused connector screws to prevent rattles.
