A Solution has Arrived
The PB-05 is ideal for lead and back-up vocals, acoustical instruments and talk-back mics. Optogate products are by far the best and easiest solution for the most common problems in live audio applications. The PB-05 senses if someone is in front of the microphone and will switch on. The microphone will be switched off automatically if no one is in front of it.
The Optogate PB-06 is our microphone gate for fixed installations, i.e. Tables, Lecterns and Podiums. This unit is ideal for Churches and Houses of Worship. The PB-06 is equipped with an infrared sensor and senses if someone is in front of the microphone in order to switch on the microphone.
The PB-07 has a Front facing IR sensor that can be used with gooseneck type microphone. Optogate products are by far the best and easiest solution for the most common problems in live audio applications. It eliminates unwanted background noise of other instruments, drums, and guitar amps into unused, open microphones on stage.
