Table Microphone

Description

The C 680 BL is a boundary layer condenser microphone with a cardioid pattern intended for table use, lecterns, and houses of worship. The transducer is internally shock mounted for immunity to impacts on the mounting surface. The microphone is provided with a roll of non-staining double-sided adhesive for positive mounting of the microphone to a table or other flat architectural detail.

The microphone has a sensitivity of 23 mV/Pa and can directly drive many microphone input stages with limited gain reserve. The microphone is phantom powered over the range from 9 to 52 volts dc.
