INTRODUCTION

The CAS series is a professional column array speaker developed by SHOW. With 1.0mm mesh and

1. 0mm grille, it can effectively protect unit from external damage and prevent dust into the speaker.
   Cabinet is made by aluminum alloy with coating, 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.

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 make the cables connected.
