Product Introduction
Laser series is a new line array speaker system introduced by HiVi hivi Company. It adopts a special three-point hanging system structure, forming a good vertical coverage directivity, high continuous sound pressure level, large dynamic state and good transient state. With its Laser series ultra-low frequency speakers, it can achieve good sound reinforcement effect with ideal external frequency division combination configuration. This system is especially suitable for various gymnasiums, halls, auditoriums, theatres, performance halls, multi-functional meeting rooms and other sound reinforcement requirements; It is equipped with special hangers, bolts, all kinds of connectors, and the automatic positioning device of the patented sound reinforcement pointing area.

Instructions for laser pointing and positioning in sound reinforcement area
1. First, make sure that the power amplifier is properly connected to the port of the 8-core waterproof speaker base (1+, 1-). When a low-voltage 15KHz sine wave signal is input, a slight high-frequency sound of the woofer will be heard. Then, continue to slowly increase the input signal voltage until the laser light outlet on the front of the speaker emits a stable beam, and the projection position of the beam is the sound reinforcement pointing area of the speaker. Note: When using this function, please mute the port of (2+, 2-) to prevent the horn from burning out. 2. Schematic diagram of laser beam positioning, as shown in the figure. Note: This pointing system is optional. Please make sure the speaker has this function before using it.
