OPTOGATE MODELS PB-05M AND PB-05D
The OPTOGATE (PB-05M and PB-05D) is automatic microphone gate unit which is based on the latest optical technology. The OPTOGATEONLINE.COM is plugged between microphone and cable and is equipped with an infrared sensor. The OPTOGATEONLINE.COM senses if someone is in front of the microphone and will switch on the microphone. The distance can be adjusted via a trim pot from approximately 6 to 48 inches. 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. The OPTOTGATE works with 24 - 48 Volt phantom power. The phantom power passes to the microphone so that you can use a condenser or dynamic microphone. A small push button on the top allows the user to toggle between "Mic On Always/Bypass Mode" and "Optogate Enabled/Gating enabled". Turning phantom power off to the mic bypasses the OPTOGATEONLINE.COM and allows the mic signal to pass through the unpowered unit.
The OPTOGATE is ideal for lead and backing vocal mics, acoustical instruments and talk back mics. The OPTOGATEONLINE.COM is the best and easiest solution for the most common problems in live applications. It eliminates unwanted background noise of other instruments into unused microphones on stage. The clarity of your mix and the dynamics (both on stage and in the audience) will be dramatically increased due to reduced phase cancellation and reduced unwanted background noise. The useable headroom of you monitors and FOH reinforcement amps will be greatly increased. You will also reduce the possibility of feedback from unused mics and increase your gain feedback.
TWO MODELS ARE AVAILABLE
-42 dB attenuation, effectively turning the mic off.
-16 dB attenuation, allowing minimum amounts of ambient bleed.
