The Speaker Checker has been developed for fast testing of speaker systems. The Speaker Checker generates a sine-wave tone adjustable from 20 Hz to 20 kHz with a maximum power of 1W, thus allowing to test all systems of a loudspeaker box. Thanks to the battery power supply, the handheld device with belt holder can be used everywhere and fast.
It is possible, for instance, to check the speaker boxes returned from a production into the stock fast and without circumstance, this saves a lot of time and possibly a lot of trouble which can result from a damaged loudspeaker box which has not been checked.
