PT-4 SPEAKER SELECTOR WITH PUREPATH AUTOFORMER PROTECTION
TM
Your PT-4 features PurePath Autoformer protection that constantly processes how many speakers are
selected and provides the purest possible path from the amplifier to the speaker. Ultimate fidelity for critical listening
can occur at any time - simply select only the room you are in and the PT selector automatically provides an absolute
pure path to the speakers selected. As you engage more pairs of speakers, the PT selector simply inserts Autoformer
protection. Autoformer protection split's the amplifier's power among the speakers selected, without wasting any
power as heat.
The left and right channels are completely separate to assure safe operation with any type of amplifier,
including those with isolated grounds (bridging outputs).
Other PT-4 features include power handling capability of up to 300 Watts Audio (100 Watts RMS) power, and
screw type connectors that handle up to 12 gauge wire.
Power Handling: 300 Watts per channel audio (100 Watts per channel RMS)
Connectors: Screw-type connectors capable of connecting 12 gauge wire.
Dimensions: 17" W x 1.75"H x 5"D.
Frequency Response: 20 - 20,000 Hz plus or minus 0.5 dB
