the negative terminal on the first speaker to the negative terminal on the second. Repeat
for each additional speaker in the array.
INSTALLATION
Perform the following steps to install and setup this speaker for operation.
1. Power off and unplug all equipment that will be connected to this speaker.
2. Determine the mounting location for the speaker. Drill three
pilot holes, 60mm apart using a 9.5mm drill bit. Use the
speaker bracket to mark the holes before drilling.
3. Using three screws (not included), secure the speaker
bracket to the mounting surface.
4. Multiply the rated RMS power output of your amplifier by 0.8
to determine the maximum total wattage for the speaker
array.
Example: If you are using the 14886 120-watt PA amplifier, the maximum wattage of
the connected speaker array is 120 x 0.8 = 96 watts.
5. Assuming you want all speakers in the array to produce the same volume level,
divide the calculated maximum wattage by the number of speakers in the array to
determine the maximum wattage value for each speaker in the array.
Example, if you are connecting six of these 14889 outdoor horn speakers to the
14886 120-watt PA amplifier, the maximum wattage value for each speaker in the
system is 96 / 6 = 16 watts.
6. Using a Phillips screwdriver, remove the terminal cover from the rear of the speaker.
7. Loosen the nut on the waterproof wire gland to expand the opening. Feed the
speaker wire through the opening.
8. The speaker has three wattage taps which are selected by connecting to the wire
terminal with the red, green, or white leads. These leads represent the following
wattage values in 70V and 100V systems.
