Pearl Mikrofonlab PML 8-CK Tube Microphone #3 including gooseneck cable

Built in Sweden in the late 50's to meet the most demanding professional standards, the Pearl 8-CK offers continuously variable directivity, giving engineers total control over pickup pattern.

Using a potentiometer on the microphone’s power supply, the polar response can be smoothly adjusted between omni, bidirectional, and cardioid, allowing precise tailoring for any recording situation.

Versatile, precise, and engineered for critical applications, the 8-CK is as adaptable as it is sonically transparent. The design is based around the legendary rectangle capsule and the AC701 tube.

Tested and serviced by Drefahl in June 2025.

PSU works on 220V. EU power cord attached.
