Installation
1. Unscrew the plastic wall plate from the speaker bracket and mark
out, drill and fix to the wall as required.
2. Line up the steel speaker bracket against the plastic wall plate at
the required tilt angle and secure using the 2 screws provided
through 2 of the punched holes.
3. Locate the speaker into the speaker bracket and secure using the
screw caps provided on the top and bottom.
4. Adjust the horizontal angle (pan) of the speaker by loosening the
screw caps, turning the speaker and re-tightening the screw caps.
5. Remove the cover on the rear of each speaker to reveal the
spring terminals.
6. Use good quality 2-core speaker wire capable of carrying
the rated power and connect to the speaker terminals. Strip
back the insulation, press down the terminal, thread the
wire through the terminal post and release to grip the bare
wire.
7. If installing in sheltered outdoor areas, fit the cover over
the rear terminal cavity to protect the wiring from moisture.
8. Connect the + and - terminals on the speaker to the
relative outputs on the amplifier as shown opposite.
