Optogate Model PB-06
The Optogate PB-06 is our microphone gate unit that can be fixed under a table.
On this model both XLR-plugs are on the rear of the device. The PB-06
is equipped with an infrared sensor as well and senses if someone
is in front of the microphone in order to switch on the microphone.
The distance can be adjusted between 15cm and 120cm with the help
of a Trim Pot. Inside the case is a 5mm hole for the possobility to
fix the PB-06 under a table.
Applications:
Optogates are the best and easiest solution for the most common problems in live
applications. It eleminates unwanted backgound noise of other instruments
into unused microphones on stage. So, the clarity of the mix and the
dynamics will be increased due to less phase cancellation and backgound
noise. It reduces the possibility of feedback from unused mics. Just
plug & Play...
