Professional Microphone Accessory

Increase Clarity
Reduce Bleed

Your typical open mic worries could be a thing in the past, as these optical microphone switches operate in response to the physical presence or absence of the performer in front of the mic, helping to clean up their live mix.

Introducing the Optogate PB-05 versions

The PB-05 is available in 2 versions.

The PB-05M (Mute) has an attenuation of -42 dB in the “Mic Off” position.
The PB-05D (Ducking) reduces the signal by -16 dB, in the “Mic Off” position.

Both units are powered via phatom power, can be used with dynamic or condenser mics, have an adjustable distance “sensitivity” and have a bypass switch on top of the unit.

Microphone with PB-05M

A Better Approach

Clean Up
Your Live Mix

Optogate uses a different approach, in that it is triggered by the physical presence or absences of the mic user. The PB-05 has a miniature infrared transmitter and receiver, which detects reflected IR from a person or instrument directly in front and noiselessly switches the signal from the mic on and off accordingly

What is the Optogate PB-05 and how does it work?

The PB-05 is an automatic microphone gate unit which is based on the latest infrared optical technology. The PB-05 is plugged between microphone and cable. It’s equipped with an infrared sensor. The PB-05 senses if someone is in front of the microphone and will switch on the microphone. The distance can be adjusted from approximately 6 to 48 inches with the help of a Trim Pot.
