Speaker Protection

Problem: Speaker-Amplifier Mismatch

High-power amplifiers used with low-power speakers may overdrive the speaker coils with excessive power during sustained high volume whereas low-power amplifiers may be overdriven causing clipping and overloading the tweeters.

 

Solution: PolySwitch devices

PolySwitch resettable devices provide soft switching into a high resistance tripped state, and automatically reset to a low resistance state when power is removed. They have essentially no capacitive or inductive reactance and cause no measurable distortion over the audio range of frequencies.
