The ECM-AW4 Bluetooth Wireless Microphone System, developed by Sony, offers a comprehensive battery-powered wireless solution for capturing audio. Designed to plug into nearly any video camera, DSLR, or recording device with a 3.5mm mini-jack microphone input, this system ensures compatibility across a broad range of equipment. The transmitter comes with a built-in microphone, and users also have the option to connect an external microphone with a 3.5mm output—supporting Plugin Power for expanded versatility. The receiver unit introduces a talk-back function, allowing for seamless communication between the camera operator and the subject, even at distances up to 150 feet.

Two-Way Communication Functionality

An outstanding feature of the ECM-AW4 system is its capability to facilitate direct communication between the subject and the device operator, effectively removing the need for a separate intercom system. This opens up opportunities for the camera operator to act as a director, offering guidance or posing interview questions to the on-camera talent, regardless of their physical distance. Both the transmitter and receiver are equipped with a 3.5mm headphone jack/audio output, streamlining the communication process and adding convenience for users in the field.

Mounting and Portability Options

To ensure flexible setup and reliable operation in diverse scenarios, the microphone system includes a belt clip and an arm band for mounting the microphone and receiver. The arm band is particularly useful for attaching the transmitter to subjects who are wearing clothing unsuitable for a belt clip. Additionally, the included carrying pouch offers protection for the transmitter during transport and storage, further enhancing the system’s practicality for on-the-go professionals.
