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.
