Optogate PB-09 - Automatic microphone switch for live applications

The Optogate PB-09 is our new automatic microphone gate unit, implemented in a table stand. Like the other models the PB-09 will switch on the microphone if someone is in front of the mic. The PB-09 contains a mic on button what can be used as "push to talk" or "mic latch" switch. These different functions are user programmable with 3 dip switches. The PB-09 contains also a galvanically separated trigger input for the mic control. The switching noise is not measureable. A red status LED indicates if the microphone is switched on. The PB-09 works with 48V phantom power and can be used in connection with dynamic mics and condenser mics. The phantom power passes the microphone. The 1,2 kg heavy body of the PB-09 is iron made and equipped with 3 anti noise rubber feet on the bottom in order for a safety silent fixed position. A mic support plate for a mic clamp is also available for the PB-09 if necessary. The PB-09 is easy to adjust from the technician and easy to use from the end user. The surface is clear and only the status led and the mic button appear for the end user.

Applications:

The PB-09 is the best all in one solution for conference applications. It helps to eliminate unwanted background noise in the sound system. The problems with open mics on conferences are past.
