1. 2 POWER SUPPLY Your condenser mic B 2 PRO needs a 48 V phantom power supply BEHRINGER assumes no liability for any damage caused by a defective phantom power supply Always mute the sound reinforcement system before you switch on the phantom power supply After power up the B 2 PRO needs about 6 seconds to stabilize 3 DIRECTIVITY With the switch on the front you can set your B 2 PRO to provide a cardioid omnidirectional or figure eight directivity pattern If the microphone is used to pick up both the signal source and ambient signals we recommend to use an omnidirectional directivity switch position left However to pick up specific instruments or voices please set the switch to the cardioid position right The figure eight directivity pattern center is recommended for example for choir miking Thanks to the figure eight directivity pattern your B 2 PRO picks up more ambient signals than when it is set to the omnidirectional directivity 4 LOW CUT FILTER AND LEVEL ATTENUATION The low cut filter can be activated with the left switch on the rear in order to filter low frequency interference such as pop sounds etc With the low cut filter on the B 2 PRO provides an almost linear frequency response with signals picked up at close proximity to the source The built in shielding minimizes the microphone s sensitivity to high frequency interference Use the right switch on the rear to activate the 10 dB level attenuator2. 78 dB A weighted figure eight Nominal impedance lt 100 Q Load impedance gt 1kQ Supply voltage 48 V Supply current 3mA Dimensions head 56 mm shaft 50 mm length 210 mm Weight approx 0 55 kg 5 MOUNTING MICROPHONE AND ELASTIC SUSPENSION 3 270 STUDIO CONDENSER MICROPHONE B 2 PRO 09B 5dB 10dB 1548 200B 25dB 30dB dB 20 0 250 Hz 500 Hz 1000 Hz 2000 Hz 270 180 Polar pattern cardioid o 0dB 5dB 10dB 15dB 20dB 25dB 30dB 90 0 0 10 0 20 0 10k 15k 20k Hz 4000 Hz 8000 Hz 16000 Hz Frequency response cardioid 240 250 Hz 500 Hz 1000 Hz 2000 Hz 180 250 Hz 500 Hz 1000 Hz 2000 Hz Polar pattern omnidirectional e 0dB 5dB 10dB 15dB 20dB 25dB 30dB 90 10k 15k 20k Hz 16000 Hz Frequency response omnidirectional dB 20 0 10 0 10 0 20 0 10k 15k 20k Hz 4000 Hz 8000 Hz 16000 Hz 180 Polar pattern figure eight Frequency response figure eight BEHRINGER is constantly striving to maintain the highest professional standards As a result of these efforts modifications may be made from time to time to existing products without prior notice Specifications and appeara
3. Remember less is often more The B 2 PRO provides a level peak around 12 kHz producing some kind of presence in this range so there is no need for high frequency EQing which could deteriorate the signal and raise the overall noise floor On the contrary the B 2 PRO provides that much desired transparency which often gets lost during recording and mixing 8 WARRANTY Is Please find our current warranty terms on our web site under http www behringer com or send us a request by e mail support behringer de fax 49 0 2154 920665 or telephone 49 0 2154 920666 9 SPECIFICATIONS Transducer type condenser 1 dual diaphragm Operating principle pressure gradient Polar pattern cardioid omnidirectional or figure eight Connection gold plated balanced XLR connector Open circuit sensitivity at 1 kHz cardioid 36 dBV 0 dBV 1 V Pa 16 mV Pa omnidirectional 37 dBV 0 dBV 1 V Pa 14 mV Pa figure eight 35 dBV 0 dBV 1 V Pa 18 mV Pa Frequency response 20 Hz 20 kHz Level attenuation 10 dB switchable Low Cut filter 6 dB oct at 150 Hz switchable Max SPL 1 THD 1 kHz cardioid 138 dB 0 dB 148 dB 10 dB omnidirectional 139 dB 0 dB 149 dB 10 dB figure eight 137 dB 0 dB 147 dB 10 dB Equivalent SPL IEC 651 17 dB A cardioid 18 dB A omnidirectional 16 dB A figure eight Signal to noise ratio 77 dB A weighted cardioid 76 dB A weighted omnidirectional

5. STUDIO CONDENSER MICROPHONE B 2 PRO User s Manual Version 1 0 September 2002 Sul BEHRINGER www behringer com ENGLISH STUDIO CONDENSER MICROPHONE B 2 PRO 1 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 Water and moisture Condenser microphones are extremely moisture sensitive Never use your microphone in close proximity to water e g bath tubs wash basins sinks washing machines pools etc When doing voice recordings always use the enclosed popscreen to safely protect the capsule from moisture Power supply Always use the power supply specified in the operating instructions Damage Take care not to drop your microphone as this can lead to severe damage BEHRINGER assumes no liability for any damage caused by the user Maintenance and care When the microphone is not in use please take it out from its elastic suspension clean it with a soft cloth and then place it in its case Place the bag containing moisture absorbing crystals close to the microphone head Caution Never dismount the screen holding the capsule as this can damage the microphone Never try to modify the printed circuit board inside your B 2 PRO This can lead to microphone damage that cannot be repaired Any such attempt will void the warranty
