The power of eight

The BP3600 immersive audio microphone is the latest addition from Audio-Technica, a premium broadcast audio tool capable of capturing stable, three-dimensional sound beds at sporting events, concerts, festivals and movie sets. The microphone houses eight compact capsule assemblies integrated into the body while remaining compact and lightweight enough for single-operator usability and simple setup. According to the manufacturer, this practical broadcasting solution captures realistic sound that will bring the recording location directly to listeners without the need for other extensive equipment.

The BP3600’s eight microphone modules extend from the body to form a cube with 15cm between each microphone assembly. Each assembly in the eight-channel, near-coincident array is equipped with a 12mm hypercardioid capsule to produce ideally separated, discrete signals and deliver immersive audio experiences.

When used in a typical 5.1.4 immersive scenario, the four upper microphone channels can be assigned to the upper speaker channels, and the four lower channels can be assigned to the lower speaker channels. This eliminates the need for additional decoding or latency processing during routing.

User-friendliness is enhanced with the main unit’s visible colour-coded and numbered channel indicator rings that allow for easy identification of channels. To ensure that onsite setup is simple when time is limited, each microphone assembly features a lock that guarantees precise, repeatable positioning and prevents accidental removal. These connector locks additionally protect the microphone terminals from the elements, including rain, and make disconnecting an assembly quick and easy. Also included is a safety strap that can be connected to drop-prevention wires when used above spectators in stadiums, auditoriums or other venues.

The end of the microphone’s grip includes a LEMO 2B multi-pin output connector for attaching the included LEMO-to-XLRM (x8) breakout cable, for routing the eight channels to a mixing console or audio interface. LEMO-to-LEMO 2B multi-pin connector extension cables are available separately for use between the microphone and the breakout cable to increase the cable run length. Phantom power (48 VDC) is required for each channel.

The microphone comes standard with eight dedicated windscreens and a microphone stand clamp with a 5/8-inch-27 to 3/8-inch-16 threaded adapter. The microphone can be disassembled and placed in the included case for protection during storage or transportation. Additional optional accessories include Rycote BBG Windshields for increased noise protection and Rycote BBG Windjammer synthetic fur covers to attenuate extreme wind noise.
