OVERVIEW

The SPT.LIGHT of UNiKA phase tester is the second generation of SPT-1 phase tester. It consists of two units, a transmitter and receiver. The SPT.LIGHT transmitter creates a pulse that is sent through an audio system. The receiver then picks up the signal at various intervals in the system, and indicates whether or not the system is in or out of phase. Every SPT.LIGHT phase tester has been thoroughly tested and offers the best value at an affordable price.

DESCRIPTION

The SPT.LIGHT phase tester consists of two units: SPT2t transmitter and SPT2r receiver. The SPT2t transmits a positive-going pulse via a speaker, or a XLR balanced connector. The SPT2t speaker is a placed near a microphone, which may be connected to the SPT2r receiver to an audio system.

Plugging into the XLR connector on the receiver disables the mic. When testing a microphone it is very important that the mic face the SPT2t speaker directly at 90-degree angle. Further more, SPT2t features a LED work light, and SPT2r features a green laser pointer.
