Connect the Loudspeakers
WARNING!:
When the AC Power is on, there is a potential of having
dangerous voltage at the output terminals on the rear of the amplifier. Use
caution to not touch these contacts. Turn off the AC Mains disconnect switch
prior to making any connections.
1. Turn the AC Mains power switch, on the back of the amplifier, to OFF.
2. Connect the loudspeaker wiring to the 8-pin Euro-style connector. Refer to Figure 15
thru Figure 23. When combining channels, QSC recommends that you connect jumpers
between the electrically same output terminals. Refer to Figure 15 and the WARNING
above the figure.
3. Install the Euro-style connector onto the rear of the amplifier as shown in Figure 24.
4. Use a Phillips screwdriver to secure the connector.
AC Power On
After connecting the outputs to the loudspeakers, you may turn the amplifier on.
1. Make sure the output gain settings for all audio-source devices (CD Players, Mixers, Instruments, etc.) at the lowest output (max attenuation).
2. Turn on all audio sources.
3. Turn the AC Mains power switch on the back of the amplifier to ON. The amplifier starts in the state it was in when power was removed.
4. You can now bring up the outputs of your audio sources.
