grille, it can effectively protect unit from external damage and prevent dust into the speaker. Cabinet is
made by plywood with light weight and solid structure. Cabinet surface is sprayed fine sand paint to
make delicate. touch. 8 pieces 3 " full-range horn unit with linear paper cone , cloth surrounding can
achieve high sensitivity. The system apply power transformers to switch power, effectively protect the
units. To prevent high power input signal damage units, they can be used in parallel to avoid causing
damage to the PA amplifier with low impedance. Locked bracket screws to fixed plate inside cabinet.
The fixing plate with 3 mm thick iron can effective decompose the bracket pull force.

CS-304 / CS-308
1) Make sure the expansion screws of mounting brackets can filmy support the product weight
before installation to avoid causing the injuries of the facilities and a worker if there is a falling.
2) Make sure the bracket is installed in vertical position and install expansion screw in the identified
location.
3) Lock the bracket (in attached) to the wall enough tightly and ensure it’s vertical between bracket and
wall.
4) Remove the 6*M8 screws on back of column and fix it to the racket via the screws( in attached).
Please make the column straight and firmly locked.
5) Adjust the column to appropriate angle with bracket adjustable angle vertical 0 °~ 30 °, horizon
-90 ° ~ 90 °.
6)Please first confirm the system you connected output of 100V, 70V. And adjust band switch to the
correct position, also the input signal must be connected correctly.
• 180 ° x 30 ° bracket (angle vertical 0 °~ 30 °, horizon -90 ° ~ 90 °)
• L bracket(angle horizon -90 ° ~ 90 °)
