Audio-Technica BP4073 Line + Gradient Condenser Microphone

Set your sound stage up for success with Audio-Technica’s BP4073 microphone. Its length of just over 9 inches and weight of 3.5 ounces lets you mount this mic with next to no heft to the end of a fish pole or the top of a minicam. Designed with a narrow acceptance angle, the shotgun mic effectively works for long-distance pickup. These features and more make this condenser microphone well-suited to broadcasting, film/TV production, and theater sound reinforcement applications.

Broadcast-quality sound comes through in multiple elements of the BP4073. Despite the short length, BP4073 provides the same directivity as other microphones up to 50% longer than its 9.2 inches. Highly directional polar pattern provides crisp and intelligible audio within the narrow acceptance angle. Direct-coupled balanced output keeps signal clean even in high-output environments. Switchable 10 dB pad lowers the microphone’s sensitivity, allowing the mic to withstand higher SPLs. Another switch for choosing between flat response or low-frequency roll off allows greater frequency control. Phantom power at 48V is required to operate this condenser microphone.

Take broadcast-quality sound with you wherever you go using the BP4073. Structural-grade aluminum alloy makes the housing lightweight and durable. Accessories are included to help shift to the physical demand of different spaces, so the mic can be mounted to a mic stand, boompole, or camera-mount microphone holder. Design elements reproduce quality sound in environments with different demands of SPLs, ambient noise, and more.
