AMP660/AMP1000 - High Power Public Address Amplifiers
Special case of the AMP1000 output terminal block
The AMP1000 has a 120V output.
This output is used to supply power to long installations to avoid voltage drops.
However, if your installation is of normal length, it is preferable to use the 100V output.
For information: 20V of voltage drop is equivalent to a cable length of 100m for a 2.5mm² section. It is
nevertheless advisable to check the voltage at the terminals of the speakers.
