Product description LR series is a brand-new line array speaker system launched by HiVi hivi brand to solve the sound pressure level attenuation caused by long-distance sound transmission. LR series corrects the wave front to make it close to the plane wave transmission, thus solving the problem of long-distance transmission. Through a special hanging system, many speakers can be connected beneficially, forming a powerful linear sound source, with high continuous sound pressure level, large dynamic and good transient state. With its ultra-low frequency speakers, it can exert its unique effects perfectly in an ideal 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 automatic positioning devices in the sound reinforcement pointing area, etc., which makes the system combination and hoisting easy to use.

Instructions for laser pointing and positioning in sound reinforcement area


1. First, make sure that the power amplifier is properly connected to the (2+, 2-) laser port of the 8P speaker base at the back of the speaker. When you input a sine wave signal of 15KHz, you will hear a slight high-frequency sound from the speaker. Then, continue to slowly increase the input signal 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. Warm Tip: When using this function, please mute the ports of (1+, 1-), (3+, 3-) to prevent the horn from burning out. 2. Schematic diagram of laser beam positioning:
