The tweeters are protected by a thermal protection circuit that increases impedance when the
current exceeds a safe level. The increased impedance reduces current to the tweeter, thus
protecting it against damage. The audible result is a decrease in high-frequency output. If this
happens, do not increase the high-frequency level on the EQ or tone control on the mixer: the
tweeter has reached its maximum power handling capacity. If higher output is required, more or
larger speakers are needed.
When volume is decreased and current returns to a safe level, the protection circuit
automatically restores full signal to the tweeter and the audio output returns to normal.
