INSTALLATION
Installation Reference
Warning: When installing the system, make sure all accessories in the installation
system meet a safety factor of no less than 5:1 or meet local safety standards.
Flying
Waterproof Line Array Speaker System
The outstanding point of the rear flying
plate indicates the current angle.
Installation Accessories:
PL312F cabinets are equipped with a flying system and 4 polyurethane casters, "
which can be easily and reliably installed and hung for various environments.
The flying system includes the PL312F flying frame, front flying bracket, rear flying
bracket (angle flying bracket on the back of the cabinet), and locking pins.
The rear flying bracket is installed fixedly on the cabinet for the convenience of
selecting the opening angle between the speakers vertically.
The PL312F flying frame is a welded steel frame, and it has a maximum capacity of
rigging a total of 16 full-frequency speakers and 4 subwoofers.

Speaker Testing Method
1. Frequency response
Use Pink noise to test the speaker in the anechoic room, adjust
the level to make the speaker work at its rated impedance and
the power output is 1W, then test the frequency response 1m
away from the speaker.
2. Sensitivity
Use full range Pink noise which was modified by EQ curve to
test the speaker in the anechoic room, enlarge the signal to
make the speaker work at its rated impedance and the power
output is 1W, then test the sensitivity 1m away from the speaker.
3. MAX.SPL
Use full range Pink noise which was modified by EQ curve to
test the speaker in the anechoic room, enlarge the signal to
make the speaker work at its instant power output level, then
test the SPL 1m away from the speaker.
4. Rated Power
Use the pink noise according to IEC#268-5 to test the speaker,
enlarge the signal for continuous 100hours, the rated Power is
the power when the speaker will not incur hot damage or
mechanics damage.
