Design

The design of the Sony ECM-B1M includes only the latest and sharpest of cutting edge of technology in the world of compact shotgun microphones. Sony didn’t hold out on any of the technical aspects within the ECM-B1M. At only 99.3mm or four inches in total length, it is one of the most compact shotgun microphones available on the market from Sony today.

The Sony ECM-B1M has eight high-performance mic capsules and advanced digital signal processing. These right mic capsules work alongside with a new beamforming algorithm that provides sharp directivity and rejects sounds from an off-axis origin. An entirely lossless audio recording experience is achievable with this product due to its direct digital audio interface.

Audio with the Sony ECM-B1M is directed through the multi-interface shoe into a Sony camera with no degradation in the sound quality and zero transportation noise that is often found to be underlying in the background with lesser quality shotgun microphones.

The high-performance mic capsules along with the advanced digital signal processing allow for Sony’s device to provide three options of directivity patterns.

Mechanical noise suppression within the Sony ECM-B1M allows for advanced shock suppression and vibration suppression from within the unit. This mechanical noise suppression within the shotgun microphone enables it to minimize low-frequency sounds, or handling, that would otherwise degrade the quality of the recording.

The mechanical noise suppression would also work to reduce audio transportation noise from cables, however, because the Sony ECM-B1M has no cables, there is no transportation or degradation to reduce.

Three options of directivity patterns, as covered in the feature section from within the Sony ECM-B1M’s product information page on Sony’s website, allow for three patterns from one shotgun microphone. The options included within this shotgun microphone include super-directional, unidirectional, and omnidirectional.

The Sony ECM-B1M comes with a low-cut filter that finds, identifies and eliminates subsonic noise through digital signal processing. This same low-cut filter built into the shotgun microphone also maximizes the recorded audio at the starting stage and reduces the need for complex post-processing in the editing room.

Controls with the Sony ECM-B1M cover a wide range of any desired adjustments to the recording levels. It also comes with an analog output, covered above, that would allow this device to be compatible with other Sony cameras that do not have a digital audio interface.

The Sony ECM-B1M comes with attenuator control to easily adjust and set optimal signal levels. All-in-all, these controls continue to reduce the need for post-processing when all the audio and video is cut together in the editing room.

There are virtually no worries about the installation of the ECM-B1M. Simply plug in the microphone and play. The plug-and-play feature of this microphone eliminates any concern of driver installations, technical communication mishaps between the Sony camera and microphone, and the undesirable process of troubleshooting connection errors.

Do you need to prepare with a few additional purchases of extra batteries for the Sony ECM-B1M? Definitely not. The Sony ECM-B1M does not use or require any batteries to operate. It simply attaches to the multi-interface shoe and is ready to go. There is also no need for external cables that would otherwise come with a risk of disappearance, like the Rode Wireless GO compact microphone system.

The Sony ECM-B1M also comes with a “dead cat” cover, or windscreen, for the shotgun microphone. This windscreen is a fur type windscreen designed to assist in the noise reduction from wind outdoors and can eliminate the added wind noise from air conditioning units indoors. The Sony ECM-B1M also comes with a carry pouch to assist with safe travels from within a camera accessory case.

How Does it Compare to Competitors?

The Sony ECM-B1M has several factors that set it apart from its competitors and make it the clear choice to take. This shotgun microphone does not require cables, batteries, and comes with both analog and digital recording options.
