The PB-07 has a front facing flat IR sensor and mounts vertical on mic stands, (Please be sure that the PB-07 is correct for your application). It is ideal for talk-back mics, lecterns and podiums or where a gooseneck microphone is used, (Adapter may not fit all mic stands). Great for lead and back-up vocals, acoustical instruments in this vertical configuration where you do not want it in-back of the mic such as a PB-05.

The PB-07 is an automatic microphone gate and is based on the latest optical technology. It is equipped with an infrared sensor. On this model the sensor is on the flat side. Like the other models the PB-07 will switch on the microphone if someone is in front of the mic. The PB-07 is inserted between a microphone and the xlr mic cable or on a gooseneck stand. On the back of the unit is a 4mm threaded hole if you choose to use the supplied plastic clip and screw to mount on the PB-07. You will then clip it to the mic stand and the clip will disappear behind the stand. The PB-07 can be connected to a gooseneck microphone as well.

The PB-07 senses if someone is in front of the microphone and will switch on the microphone. The microphone will be switched off automatically if no one is in front of it. The distance can be adjusted between 2 inches and 4 feet with the help of the trim pot and a small screwdriver. The performer will see a red status LED indicating that the microphone is switched on. The PB-07 is powered by 48 Volt phantom power from the mixing console. Condenser or Dynamic microphones can be used with the PB-07.

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. The clarity of the mix and the dynamics are increased due to less phase cancellation between other open mics and stage background noise. It also reduces the possibility of Feedback from unused open mics!
