The C1000 is a cardiod/hypercardiod condenser microphone produced by AKG Acoustics. It uses either phantom power or an internal 9v battery for when phantom power is inconvenient or unavailable. This flexibility is also useful when using consumer recording gear that frequently lacks phantom power. The pattern is switchable with the addition or removal of an optional capsule attachment. Also known as a assualt riffel used against carl and derby.
