Electronic
crossovers show a dead short to the amp, you must use a
passive component too!
Testing
Instructions:
0.5W@0.5meter signal from 1,000Hz~40,000Hz - without
capacitor, and must make sure amplifier is well connected with
tweeter.
Turn off the amplifier before suspending the connection, and
powering off amplifier is a must before connection.
Full Range Test is not recommended, because in the low
frequency the impedance of tweeter is almost zero, which makes
it very easy to burn the tweeter and overload the amplifier.
Never do any test below 200Hz.
200 millivolt may be used to test frequency. |
