2. GENERAL DESCRIPTION
Note:
Screws to mount the
bracket are not available
3. DESCRIPTION ON OVERLOAD PROTECTION
The speaker unit is equipped with an overload protector. The system shall protect the speaker unit from overload
input which exceeds the allowed capacity.
Speaker’s volume will turn lower if the input to the speaker exceeds the maximum capacity of the speaker.
In such event, please turn down the amplifier volume to the minimum level and wait for 10 seconds. The system
shall automatically reset to normal condition. You may then gradually re-adjust the amplifier volume to the level
lower then the previous volume.
Important Note!
The system does not entirely protect against overload. Prolonged overload input to the speaker unit will cause
the system to malfunction. As such, the overload input will flow in and damage the speaker unit.
It is important to prevent prolonged overload input exceeding the maximum limit from flowing into the speaker
unit.

6.2.3. Installation on Ceiling
For ceiling installation, please unscrew all screws (4 pieces) on the subwoofer. Take note of the distance
