BM 6620 Boundary Microphone
Description
The BM 6620 is a low-profile omnidirectional, condenser boundary microphone
designed to fit into the flush mounted conference units in the DIS DCS 6000 Digital
Conference System.
The BM 6620 is available for retrofit in the standard flush-mounted units FC 602xF
and FD 612xF by replacing the XLR socket with the boundary microphone in the
plastic adapter. The molex mini connector fits with the microphone connector on the
PCB.
It can also be custom ordered for use with other FC/FD and FC/FD 6xxxF units and
delivered already mounted in the units.
Features
• Boundary microphone for custom fit flush-mounted conference
units
• Low-profile omnidirectional condenser boundary microphone
with 360° pickup angle
• High-quality sound reinforcement
• RF resistant
• Isolators for providing mechanical dampening of mountingsurface vibration
• RoHS compliant
• Standard fitting for FC 602xF and FD 612xF units
