OUR PART # CARDIOID-ST
A stereo pair of cardioid condenser microphones, consisting of two CMC6U preamps (which form the body of the microphone), two MK4 capsules, two SG20 stand clamps and two B5D windscreens.
The CMC 6 is designed for standard 48- and 12-Volt phantom powering. Its circuitry recognizes the supply voltage and adjusts itself automatically. Its performance characteristics remain essentially the same either way; mainly, the difference is that the current drawn at 12 Volts is greater than at 48 Volts. However, the 12-Volt mode consumes less power and might be preferred for battery-powered recording.
The microphone amplifier provides the electrostatic charge which the capsule requires in order to produce a signal. Since only a miniscule amount of current is contained in this signal, amplification of the current is required. To avoid interference to the signal on the way from the microphone to the input of the mixer or preamp, the signal is conveyed at low impedance and in balanced form. The CMC 6 amplifier offers a symmetrical, transformerless, direct-coupled Class A output stage with low impedance, low distortion, and high freedom from interference.
The MK4 capsule offers the highest sound quality, flat frequency response, optimal rejection of rear-incident sound, and a directional pattern that remains constant throughout the audio frequency range. In the diffuse sound field it shows only a mild rise around 10 kHz; the sonic impression thus remains free of coloration even when sound is arriving from all sides at once. The sonic impression is thus free of coloration whether sound is arriving at the front or at the sides of the microphone, as well as for diffuse sound (reverberation) in a room.
