No time for manuals? No problem, this will take only 3 minutes of your time to read it and you will have more fun and success with your new Optogate device. The Optogates were designed for professional applications and to be used by experienced sound engineers and technicians only.

Typical Operating Instruction
- Plug in the Optogate
- Run phantom power to the mic (there will most likely be a switch on your mixer for this, almost all mixers have these)
- Click the bypass switch on top of all of the Optogates you are using and dial in the PA for the best tone and gain before feedback with the Optogate bypassed …ie. mics are on, the light stays on no matter where you are physically located)
- Click the bypass switch again and activate the Optogate (light/mic turns off when out of range)
- With a small screwdriver set the distance you want the Optogate to turn on/off (based on your mic technique)
- You’re done!, you will now have way better sound than you are used to hearing…it’s that simple….
The PB-05 is available in 2 versions: PB-05D Dynamic Ducker with –16dB attenuation and PB-05M Mute with –42 dB attenuation in “Off” position. The Dynamic Ducker version has a small “D” on the faceplate engraved.
The Optogates work with 24-48V phantom power. Just switch on the phantom power on the console/mix and the Optogate is active. The phantom power passes through the Optogate to the microphone. If you use dynamic mics you can “remote control” the unit with the phantom power switch. The microphone signal passes through the optogate when the phantom power is switched off. Before turning on or off the phantom power please mute the channel in order to prevent phantom power switching noise.
The PB-05M and PB-05D have a small switch on the faceplate. This gives the user the advantage to switching between the “Optogate enable” mode and “ Mic on always” (bypass mode) function. One push on the button will switch modes. One more push will enable again the Optogate gain reduction function. The Optogate function is enabled when the phantom power is switched on, regardless, what function was active before. So, the engineer can reset the PB-05M or PB-05D to the “Optogate enable” function by switching off the phantom power for at least 3 seconds if the performer forgot to enable it.
You have already found 3 LED devices on one side. The middle device is a red status LED. It indicates if somebody is in front of the unit and the microphone is switched on. If no one is in front of the mic and the red led is on, then you are in bypass mode (mic always on). The outer LED’s are the infrared transmitter and the receiver. The transmitter will send 16 pulses per second if the phantom power is switched on. The Optogate will switch the mic on if there is any signal reflected from a surface back to the receiver.
The distance from the mic to the performer in which the unit opens and closes is adjustable with the help of a 12-turn spindle potentiometer inside. On all units, the distance will increase by turning the pot to the right for a maximum distance of about 4 feet and will decrease the distance by turning the pot to the left. Please be aware that some dark materials are not able to reflect infrared signals back very well, which in turn might decrease the distance. Please experiment with the potentiometer to fine-tune the distance together with the performer before using live. It also would be helpful to have your show lighting active while adjusting. The width of the sensor is about 15 degrees wide from the unit. The mic will be switched off if the artist moves out of this angle.
When you turn the pot to the left eventually you will hear a light click of a spring. You cannot overturn the pot. You are now at the shortest distance range. When you start to turn the pot clockwise, you will find that the distance range will change very slowly in the first few turns. After a few turns, the distance will change more rapidly until you reach the maximum range. If you turn the potentiometer clockwise (right) out of the usable area, the mic will be switched on completely. If this happens, just turn the pot slightly to the left until the Optogate works again.
