Function
The SINE PA 120 studio power amplifier is designed for installation in 19" racks. Please
ensure that it gets adequate ventilation.
Use the included power cable to connect the PA 120 to an AC power source. Connect
both inputs to the outputs of your mixer and the outputs to your speakers (4-8 ohm). Turn
both VOLUME controls completely down.
The "On" and "Protect" LEDs will light up when the power is switched on. The "Protect"
LED will go out after 1 to 2 seconds.
The power-up delay needs around 10 seconds to become active after turning the
amplifier off briefly. After turning off the amplifier's power, wait at least 10 seconds before
turning it back on to prevent damaging your speakers (power-on click).
The amplifier's output power has not been limited in order to ensure its high pulse power.
If the amplifier is overloaded for extended periods, the thermal protection circuit will cause
the signal to be distorted continuously. Please turn down the volume if this occurs.
