Common name: Altec M29
Production Status: Discontinued / Vintage
The M29 is a small diaphragm vacuum tube condenser microphone. It is part of the M-series (M11, M20 and M30 Systems). It uses the Austrian manufactured 29A cardioid capsule connected to the 29B amplifier body that houses the circuit based around a 5840 vacuum tube. The microphone is connected to a 525A power supply unit via a 15 ft. cable. A second cable connects the power supply unit to the receiving equipment. The 29A capsule uses a 60v polarisation voltage while the previous 21D needs 200v so older power supplies need to be modified in order to be used with the M29. Includes 166A stand mount, 169A shock-mount, 525A power supply and cables.
