Microphone amplifier for pocket transmitters

Overview | Application | Specifications | Downloads
Operating voltage4 - 10 V
Current consumptionca. 1 mA
Sensitivityca. 0.6 times the value as measured with a standard CMC microphone amplifier. For example with the MK 4 cardioid, the sensitivity is about 8 mV/Pa, the maximum sound pressure is 130 dB SPL and the equivalent input noise is 29 dB CCIR or 18 dB A-weighted.
Frequency responseThe frequency response characteristic will be that of the capsule which is chosen.
Maximum output voltage with 20kΩ load impedance´900 mV (-1 dBV)
Maximum output voltage with 2kΩ load impedance560 mV (-5 dBV)
Output impedanceat 1kHz: 15 Ω
Length38 mm
Diameter20 mm
Weight25 g
Length of the output cable2 m standard; other lengths available on request
