1.1 Introduction Thank you for purchasing this original Brauner microphone and thus supporting a part of the world famous German craftmenship and our love for quality, detail, precision and persisting values. Our microphones go to the full extent of what is physically possible today to achieve unparalleled results. To reach this high level of perfection only best components are carefully selected, assembled and calibrated to become these wonderful works of art and sound.
2.0 Safety Instructions Tube equipment runs on fairly high voltages that can be lethal in case of direct contact. Brauner products comply to all international safety regulations, are tested severely and can therefore be used safely and without any risks if the following regulations are met: 1) Please read this manual carefully.
2.1 Setting Up Experienced users: If you already have experiences with tube microphones, setting up and working with this Brauner microphone shouldn‘t be a problem to you. Mount the suspension on a stand, insert the microphone and connect the cables. If you‘re not used to the Brauner microphone suspension read the according chapter in this manual. New users: If this is your first Brauner tube microphone, please read this manual carefully.
2.4 Inserting The Microphone Before inserting the microphone into the suspension you should have a look at the two black collar rings on each end of the suspension‘s inner cylinder. These rings can be turned 360° and the little white dots should align with the black screws on the cylinder to be in the open position (see picture). Now insert the microphone into the suspension with the grill first.
3. 0 Power Supply (Remote Control) The power supply is built as a module to fit into any 19 inch studio rack next to preamps and effects or to be used as a stand alone device. It also serves as a remote control unit for the microphone providing you with an adjustment wheel for its directional pattern and a switch for the 10 dB pad (VM1/VMX) respectively the desired microphone circuit (VMA) on the front panel.
3.2 10dB-Pad (VM1/VMX only) The 10 dB pad allows you to dampen the microphone‘s sensitivity by 10 dB in order to handle a higher possible sound pressure level before the impedance converters start to distort. As the microphone is capable of handling a sound pressure level of up to 140 dB without any significant distortion or the typical compression artefacts tube microphones usually show, you will probably need this switch only on very rare occasions. 3.
3.6 Adjusting The Voltage Selector/Changing Fuses Before operating the microphone at a new location always make sure the voltage is set to the right value. It can be set to either 115V or 230V. To change the setting, turn off the power supply and disconnect the power cable. Take out the fuse holder which is right next to the power connector by squeezing the little latch.
4.0 Maintenance and Care We take great care and attention when we manufacture our microphones. We only use the highest quality components available, many of which are exclusively manufactured according to our specifications and individual needs. All components must pass our severe QC and selection processes without which the production of such a delicate microphone would not be possible.
