Common name: Schoeps CMT 24
Production Status: Discontinued / Vintage
The CMT 24 is a phantom powered small diaphragm transistor microphone first produced in 1964. It features a metal diaphragm capsule with a cardioid polar response. It has a linear frequency response between +/- 90° with excellent directivity thanks to an attenuation of more than 25 dB at 180°. It uses a radio-frequency circuit in which the capsule modulated a radio-frequency carrier and a transformer-less output stage with coupling capacitors. The microphone is insensitive to temperature up to + 70° Celsius, moisture, electric and magnetic fields. The CMT 20 series is powered by 8.5 V phantom power.
