PROTECTION

3

The tweeter in the Alien S51 is protected by a thermal protection circuit, which
increases impedance when the current exceeds a safe level. This reduces current to
the tweeter, thus protecting it against damage. 

The audible result is a decrease in the output from the tweeter. If this happens, do
not increase the high frequency level on the EQ or the tone control on the mixer, as
this might cause damage to the tweeter. At this time the tweeter has reached its
maximum power handling and 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.
