Speaker Outputs; Mains Switch; Ground Lift - HK Audio L.U.C.A.S Bedienungsanleitung

2. Speaker Outputs

The two upper cabinets are connected via two Speakon sockets.
These have an impedance of four ohms each to make the most of the
power amps' output. For this reason, the system can drive no more
than a single top per channel and you won't find jacks for connecting
additional cabinets.
3. AC Power
Use this socket to connect L.U.C.A.S to an AC power supply. Before
you plug the system into a wall outlet, ensure your local mains volta-
ge matches the specification indicated on the subwoofer. If you
attempt to run L.U.C.A.S on the wrong mains
voltage, you can seriously damage the power amps.

4. Mains switch

After you have connected all the necessary cords, switch the system
o n .

5. Ground Lift

When it is pressed, it separates the signal ground from the
chassis ground, enabling you to eliminate potential ground loops.
