Optogate Model PB-07
After taking into account our customers suggestions we developed the PB-07. 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. A red status LED indicates if the microphone is switched on.
The PB-07 will switch off the microphone if nobody is in front of
the mic. The distance can be adjusted between 15cm and 120cm with
the help of Trim Pot. On the back is a 4mm threaded hole for the possibility
to mount a clip on the PB-07. In this case the PB-07 can be installed
on a mic stand and will disappear behind of the stand. The PB-07 can
be connected to a gooseneck microphone as well. The PB-07 works with
48 Volt phantom power and the phantom power passes on the microphone.
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...
