There are many products on the market what could get more "intelligence" inside!

Optogates were developed in 1999. I work in the music business since 25 years and we served about 2000 concerts and other events with professional equipment during this time. We originally developed the Optogates for our own projects but quickly recognized the wider market potential. The circuitry was refined and the PB-05 was developed for local and export sale.

The PB-06 followed shortly after following useful suggestions from clients. The company is small and prides itself on attentiveness to customer's needs. This is one reason that Optogate sales grow steadily at 30% per year. Another is the product itself, made to German levels of quality and performance.

In June 2004 the PB-07 was released and the Optogate design and production has become a division within the company and thousands of units are in use around the world.

In March 2007 we introduced the programmable mic table stand version PB-09. In June 2007 we got our first pick and place machine and changed from the pure thd pcb technology to a mixed smd - thd pcb technology. This technology results in better mechanical performance. In April 2009 we exhibited the new Mini Audio Lab at the Prolight & Sound in Frankfurt. The response was great due to the build in feedback ident function and other features. the Mic Lift v2 followed at the PLASA show in London. Some other useful devices were developed in 2010 and 2011. A second pick & place machine in 2011 enabled us a more flexible and faster production of our products. However, there are already about 4000 PB-05 wordwide "on the road". Due to the experience with these devices we were able to increase the quality of our products. The idea with the electronicbox devices came with my never ending "fun work" at my Shovelhead. Our customers have already installed a few hundred of these control devices in great custombikes within the last 2 years and they are very happy with it.

However, due to some new developments in the "new energy" field we installed a new department within of our company, the "SolarelectriX" area, where we publish some new and affordable products.

Green Environment

By the way, Here in our company is the word sustainability an important issue and not just an advertisement phrase! The packages from our suppliers are be collected and go with our products to our customers. This helps us to reduce waiste to a minimum. We are a member of the BWE and Greenpeace. Our workshop and production rooms are equipped with a room power control what helps to switch off unused equipment. We already changed our old fluorescent lights in the manufacturing area against selfmade CREE XLAMP bars. This investment increased the light output from 400 lux to 1100 lux and reduced the power consumption from 60 Watt to 18 Watt per working place. This saves about 550 kw/h p.a. Our building is insolated to a German "KW40" standard. A 20 squaremeter solar system heats up this area for almost 8 months p.a. A 14 KW photovoltaik systems provides a balance to the consumed external supplied electrical energy. A ventilation system with a cross heat exchanger and a 50m geothermal heat exchanger before it supply a good ambient air in our rooms with very low transmission losses. A small wind turbine will follow soon. We developed 3 solar charge and discharge controller and sell it under the brand name "Solar ElectriX" Our long term goal is to be independent from external supplied energy. In the front of our building we have installed a free charge station for E-mobiles and we are listed in the german "Drehstromliste" as charge station for this growing technology.

Mic-Mute Automatic Microphone Switch by Jamie Rio
Here´s the scenario: you´ve got a loud guitar player who also sings backups on your stage. When he is in front of his mic, your mix is perfect. As soon as he steps away from his mic, you pick up a lot of extra Ulli roth guitar in your mix and it all turns to crap. Or you have a drummer who sings, and his always on, hot vocal mic is making the drum mix sound like snot. The thought of muting these mics at the appropriate time is daunting´especially if you have never mixed the band before and you are shooting from the hip as it is.
Well, here´s the solution. It´s a small device (about the size of a cigarette lighter) that plugs in between your mic and mic cable. It incorporates an electronic eye that controls an automatic mute switch. When the eye sees your smiling face the switch turns on. When it doesn´t, the switch turns off. It´s simple and amazingly effective. The distance that the eye sees is adjustable and the on/off effect is noiseless.
I used it with a loud guitar player and with a drummer. With the drummer it was great,as he never really varies the distance from his pie-hole to the mic. With minimal adjustment for distance, I got what I needed: vocals when he was singing and dead air when he wasn´t. It worked okay with the guitarist, but he has a tendency to work the mic pulling back when he is really pushing for a high note. This generally works well and I don´t have to overly compress the vocal because he actually has mic technique. But the Mic-Mute does not take technique into account and the mute kicked in a few times when he pulled back. A little adjustment of the distance control should havehelped, but I wasn´t getting it.
Bottom line is that for singers who are right up on the mic all the time, the Mic-Mute works wonders for cleaning up the mix. It also works on phantom power, so don´t worry about batteries. This is a great little tool. Everybody should have a couple in their toolbox. Manufactured in Germany.
What it is: Small individual mic mute Who it´s for: Sound guys and bands who want more control over their mixes Pros: It turns a mic on and off when you want Cons: Doesn´t always work with mic technique. Either on or off (no subtleties)
