The PB-05 M is an automatic microphone gate unit with -42 dB attenuation in "Mic Off" state. The PB-05 M is plugged between microphone and cable. It's equipped with an infrared sensor. The PB-05 M senses if someone is in front of the microphone and will switch on the microphone. The distance can be adjusted between 15cm and 120cm with the help of a Trim Pot. The microphone will be switched off automatically if nobody is in front of it. A red status LED indicates if the microphone is switched on. A small button on the top side allow a constant switch on of the mic if required. The PB-05 M works with 48 Volt phantom power. Condensor microphones can be used in connection with the PB-05 M. The phantom power passes the microphone. A small push button on the top allows the user to toggle between "Mic On" and "Optogate Enable". The PB-05 M is ideal for lead and backing voval mics, acoustical instruments and talk back mics. The PB-05M ist 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.
