Crown International is now offering professional recording microphones in matched pairs; the CM-700 cardioid condenser mic, and the CM-150 omnidirectional condenser mic. The microphones will be matched in sensitivity and frequency response to within 1.5 dB.
The stereo pair of the CM-700 or CM-150 work great for pro or semi-pro recording of classical music ensembles, folk groups, drum sets, pianos, vocals, percussion, and so on. A key feature of the CM-150 omnidirectional microphone is its pre-aged titanium diaphragm, making it extremely stable over a wide range of environmental conditions. Several audiophile touches enhance the CM-700's sound quality: an ultralight diaphragm, humbucking transformer, polycarbonate capacitors, and a gold-plated 3-pin connector. Both models have a very smooth, wide-range frequency and off-axis response, which gives them a pure natural sound. They preserve the delicate timbre of acoustic instruments, yet can reproduce all the power of a pipe organ.
The self-noise of these microphones is very low, permitting clean, noise-free recordings. The mics can handle very loud sounds without distortion. Protection against static and RFI is also included. The output is balanced, low impedance, which allows long cable runs without hum pickup or high frequency loss. Powering is by 12-48V phantom power.
The CM-700 frequency response is 30 Hz to 18 kHz (50 Hz to 16 kHz +/-2.5 dB); self-noise is 21 dBA. The CM-150 frequency response is 20 Hz to 20 kHz +/- 1.5 dB; self-noise is 19 dBA.
