Miniaturized condensor microphone omnidirectional capsule

The Audix M1280B is a miniaturized condenser microphone featuring a fully integrated preamp and a detachable cable. This M1280BO listing identifies the microphone as the omnidirectional-capsule version. Audix describes the M1280B as having complete immunity from RF interference caused by cell phones and GSM devices, addressing a specific concern when microphones operate near common wireless equipment. Its documented applications include acoustic instruments, room miking, and speech.

Ideal Use Cases

The supplied application guidance recommends the M1280B for acoustic instruments, room miking, and speech. The omnidirectional capsule specified for this listing distinguishes it from the other capsule configurations available in the M1280B range. For buyers comparing versions for a particular microphone position or production requirement, the capsule designation is therefore an important part of product selection. This model is intended for applications where the specified omnidirectional configuration aligns with the planned use.

Why Choose This Model

The M1280B combines three clearly documented design elements: a miniaturized condenser microphone format, a fully integrated preamp, and a detachable cable. These features define the product without requiring a separate description of an external preamp assembly. The detachable cable is also a practical point of distinction for system planning, cable handling, and replacement decisions. For environments containing mobile phones or GSM devices, Audix’s stated complete immunity from the RF interference caused by those devices is another central reason to consider this model.

Installation and Integration

Integration begins with confirming that the M1280BO omnidirectional capsule matches the intended microphone application. The cable is detachable rather than permanently fixed to the microphone, while the preamp is fully integrated into the M1280B itself. Those two details should be considered when planning the signal path and physical arrangement. The supplied product data does not specify the connector type, cable length, mounting hardware, power requirements, dimensions, or weight, so those items should not be assumed from this listing.

Performance Highlights

The defining performance-related statement supplied for the M1280B is its complete immunity from RF interference caused by cell phones and GSM devices. This directly addresses interference originating from those named wireless devices. The condenser design, integrated preamp, detachable cable, and omnidirectional capsule complete the documented configuration of this SKU. No frequency response, sensitivity, maximum sound pressure level, self-noise, impedance, or output-level figures were included in the source data, so no unsupported numerical performance claims are presented here.

What Makes It Different

Capsule choice is the main distinction to note within the M1280B family. The general M1280B description identifies a cardioid-equipped version and states that hypercardioid, omnidirectional, and shotgun versions are also available. This product title specifically identifies the omnidirectional capsule, and the SKU is M1280BO. That combination separates this listing from the cardioid, hypercardioid, and shotgun configurations while retaining the documented M1280B features: miniaturized condenser construction, a fully integrated preamp, a detachable cable, and immunity from RF interference caused by cell phones and GSM devices.

Final Assessment

The Audix M1280BO is the omnidirectional-capsule listing for the miniaturized M1280B condenser microphone. Its documented strengths are specific and easy to evaluate: an integrated preamp, a detachable cable, stated immunity from cell-phone and GSM-device RF interference, and suitability for acoustic instruments, room miking, and speech. Buyers should choose this version when the omnidirectional capsule is the required M1280B configuration and confirm any unlisted connection, power, mounting, or dimensional requirements separately.
