AKG C 680 BL is a boundary layer condenser microphone with a cardioid pickup pattern designed for table use, lecterns and houses of worship. The transducer is internally shock-mounted to resist mounting-surface impacts and ships with double-sided adhesive for non-staining tabletop mounting. It offers a 60–20,000 Hz response, impedance below 200 ohms, and requires 9–52 V DC phantom power via a 3-pin XLR cable (3 m).
