AKG C 562CM OMNIDIRECTIONAL-HEMISPHERICAL CONDENSER BOUNDARY MIC

C 562 CM 

Small, low-profile boundary layer microphone
Wide frequency range
High sensitivity
Ideal for inconspicuous installation in a room
Suited for surveillance or recording
 
The C 562 CM flush-mount boundary microphone uses the same transducer as the C 562 BL.
The C 562 CM has been designed specifically for permanent, "invisible" mounting in ceilings,
walls, tables, stage props, etc.
Owing to its high sensitivity, the C 562 CM is a perfect tool for surveillance or live recording
since a single microphone can cover an entire room. The supplied XLR phantom power adapter
connects to the microphone cable through a miniature connector so installation holes can be
smaller than the diameter of the phantom power adapter.
