Pm288 is an advanced professional and cutting-edge sound engineering installation and debugging test instrument, which is the most ideal small test tool for sound engineering installation. It can accurately test the phase difference of various sound field systems, and it is an essential test tool for sound engineering installation and debugging, bringing extremely simple and convenient, time-saving, labor-saving and heart-saving efficiency to engineering installation and debugging. When more than two speakers are used in a system, it is very important to know whether the operation direction of each speaker's paper basin is consistent. At this time, pm288 speaker unit phase tester plays an important role.
The instrument is powered by 9V battery. It's easy to replace the battery. It's easy to carry and operate. It's a device that anyone can use. It can be used for the phase accuracy test of any sound system, especially for the current popular public address sound system, professional sound combination system, linear array sound system, linear sound source sound column sound system, hifi sound system, automobile sound system, home theater and other combination sound occasion tests. The system consists of two hand-held units. Pm288-a can generate its own pulse sound signal, and then output the sound signal of 1 second and 1 Hz through the XLR seat for pm288-b test.
