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. If the amplifier is 100V type, select the required wattage
output on the rotary switch inside the rear speaker
compartment.
7. If the amplifier is not a 100V type, ensure that the total
speaker load on each output is no lower than that stated
for the amplifier.
Select the 16Ωoption on the rotary switch and connect
1 x BHV speaker for a 16Ωload,
2 x BHV speakers in parallel for an 8Ωload or
4 x BHV speakers in parallel for a 4Ωload.
8. 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.
9. If installing in sheltered outdoor areas, fit the cover over the rear terminal cavity to protect
the wiring from moisture.
10. Connect the + and - terminals on the speaker to the relative outputs on the amplifier.
