A microphone that and our love for quality, detail, precision and persisting values.
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 bottom 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 contains two seperated supplies for each mircophone. Thereby the VM1S can be used as a single microphone and in stereo mode the highest possible crosstalk rejection is achievied. It also serves as a remote control unit for the microphone providing you with an adjustment wheel for its directional pattern.
3.2 Power Supply Back Panel On the back panel of the power supply there are four connectors: power, microphone (Tuchel connector) and the two signal outs (XLR phase signal on pin 2). Additionally there is a ground lift switch for each XLR out and the voltage setting/fuse holder. 3.3 Ground Lift Switch The ground lift switch detaches the ground pin (pin 1) of the XLR output from ground and can be set to three positions. Safety earth is never detached of course.
