PC218 Phase Polarity Tester Checker Detector Audio Speaker Microphone Sound Testing
Description:
1. PC218 is an advanced professional and sophisticated sound engineering installation and commissioning testing instrument,which is the best small test instrument for audio test project,It can accurately test out  a variety of phase differences of audio sound field system.which is the necessary testing tools of sound engineering installation and commissioning. This instrument can bring simple and convenient, saving time, saving effort, efficiency to sound engineering installation and commissioning.When there are two or more speakers in one system,you need to make sure that the same of very operational direction of the speaker cone speakers,which is very important. at that time,the stereo speaker unit phase tester can play an important role.
2. The instrument uses a 9V battery, replace the battery is simple and easy to use,carry and operate.and can be used for the phase accuracy test of any Sound System.Particularly suited to the testing of popular public radio sound system,Professional audio combined system,Line array sound system,Line source frets sound system,HIFI stereo systems, car audio systems, home theater and some combined sound occasion.The system consists of two hand-held units, PC218-A pulse can produce their own sound signal and then output the sound signal of 1Hz 1 second through XLR  for PC218-B to testing.
