BH 2 is a fixed cardioid condenser microphone with one large, true electrostatic capsule inside the compact head made by new golden drops technology. The new special capsule has single, less centre tap diaphragm and patterned variable sputtering, using specially mixed alloy for coating.
Transducer type electrostatic
Operating principal pressure gradient
Diaphragms active diameter 27 mm
Frequency range 20 Hz to 20 kHz
Polar pattern Cardioid
Output impedance 50 ohms
Rated load impedance >100 ohms
Suggested load impedance >250 ohms
Sensitivity at 1000 Hz into 1000 ohms load 21 mV/Pa
S/N Ratio CCIR 468-3 weighted 76,5 dB
S/N Ratio DIN/IEC 651 A-weighted 87,5 db-A
Equivalent noise level DIN/IEC A-weighted 6,5 dB-A
Maximum SPL for 0.5% THD at 1000 ohm load 134,5 dB
Dynamic range of the microphone preamplifier 128 db
Phantom powering voltage on pins 2 & 3 of XLR +48 V (+/-4 V
Current consumption 1,5 mA
Output connector 3-pin XLR male, gold plated contacts
Signal polarity positive toward pressure on a frontal diaphragm produces positive polarity voltage on XLR pin #2 relatively to pin #3
Dimensions 203 x 51 x 28
