The wide range of frequency as well as capability of generating high sound pressure level make it an efficient
speaker to be used in a spacious room.
It is consisted of a subwoofer and four pieces satellite speakers.
he provided brackets allow the speaker to be mounted on various locations and direction radiations.T
The mounting brackets come together with the product as accessories.
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
