SAFETY PRECAUTIONS Detailed safety precautions: Please read all safety precautions and operating instructions before you attempt to operate the unit. Keep all safety precautions and operating instructions for future reference. [. . . ] Always mute the sound reinforcement system before you switch on the phantom power supply. DIRECTIVITY, LOW-CUT FILTER AND LEVEL ATTENUATION The capsule used in the B-1 with cardioid characteristics is ideal for the directional recording of instruments or individual vocals. Cardioid characteristics represent the most frequently used polar pattern in recording situations. With this, unwanted sound in reverse phase is not picked up. 2 3. DIRECTIVITY, LOW-CUT FILTER AND LEVEL ATTENUATION STUDIO CONDENSER MICROPHONE B-1 The low-cut filter can be activated with the switch on the front (position: left), in order to filter lowfrequency interference such as pop sounds, etc. With the low-cut filter on, the B-1 provides an almost linear frequency response with signals picked up at close proximity to the source. The builtin shielding minimizes the microphones sensitivity to high-frequency interference. Use the same switch to activate the -10 dB level attenuator (position: right), which should be used with pulse-type signal sources producing high sound pressure levels (e. g. With the switch set to its center position, both functions are disabled. 4. MOUNTING MICROPHONE AND ELASTIC SUSPENSION Attach the enclosed elastic suspension to the microphone stand. Open the elastic suspension by pressing the two circular levers, then insert the B-1 from above. 5. AUDIO CONECTION/LEVEL SETTING Use a balanced XLR microphone cable with the following pin assignment: pin 1 = shielding; pin 2 = +; pin 3 = -. Since your B-1 features gold-plated contact points throughout, we recommend that you use only microphone cables with gold-plated connectors. Adjust the gain control in the microphone channel of your mixing console so that the peak LED lights up only occasionally or never at all.
