Product Detail
The Sony ECM-W3 is a top - notch dual - channel wireless microphone designed for high - quality digital recording. It consists of two microphone - transmitters with high signal - to - noise ratio microphone units and a dual - channel receiver. The digital audio processing and wireless transmission allow you to capture two speakers' voices clearly and with low noise. With high - quality digital sound recording, it uses high S/N ratio microphone units in the transmitters for clear, low - noise voice capture. Connect the dual - channel receiver to a Sony camera supporting the Multi Interface (MI) Shoe, like those in the α™ series or vlog cameras, and record high - quality audio directly with minimal noise. The microphone comes with noise - suppressing filter functions. A digital signal processing noise cut filter effectively removes noise, and a low cut filter reduces low - frequency noise, streamlining post - production. It's compatible with the Multi Interface (MI) Shoe, enabling easy attachment to Sony cameras without cables. This offers greater freedom and mobility during shooting, without interfering with the vari - angle LCD monitor. The ECM - W3 provides the convenience of wireless operation. With Bluetooth 5.3 and LC3plus codecs, it has low power consumption, low latency, and high sound quality, and can communicate up to 492ft (150 m) in clear line - of - sight areas. It also features safety and attenuator functions. The safety function records two audio signals simultaneously, one at normal volume and one 20 dB lower, reducing clipping risk. The attenuator function lets you set the recording level according to audio volume. There are multiple audio input/output options. A 3.5 mm mini jack (monaural) on the microphone side serves as an external input, and a 3.5 mm mini jack (stereo) on the receiver side is for audio output. You can also output digital audio (48 kHz / 24 bit) via USB cable to a smartphone, PC, or other compatible device. Compact and lightweight, both the microphone - transmitters and receiver are dust - and moisture - resistant, suitable for outdoor use. Status notification functions like the LINK lamp and POWER lamps help prevent recording errors. The kit includes a microphone (transmitter), a receiver, a charging case, and accessories such as wind screens, connector protect, a holder/stand, a pouch, and a charging case. It's compatible with various Sony cameras and has specific technical specifications for temperature, audio output, etc.
Using the Sony ECM - W3 is easy. First, charge the microphone - transmitters and the receiver using the provided charging case. Then, attach the receiver to a Sony camera that supports the Multi Interface (MI) Shoe. You can also use the 3.5 mm audio output jack on the receiver to connect it to other devices without an MI Shoe. When using the microphone - transmitters, turn them on and pair them with the receiver. They can capture the voices of two speakers wirelessly, and you can move around freely within a distance of up to 492ft (150 m) in clear line - of - sight areas. For better audio quality, you can use the noise - suppressing filter functions. The noise cut filter and low cut filter will reduce unwanted noise. If you're recording loud sounds, use the safety function to avoid clipping. You can also adjust the recording level with the attenuator function. When not in use, store the microphone - transmitters and the receiver in the charging case. Keep them in a dry place and avoid exposing them to extreme temperatures. The operating temperature range is from 0 - deg C to +40 - deg C (+32 °F to +104 °F). Clean the microphones gently with a soft cloth. If you need to use an external microphone, connect it to the 3.5 mm mini jack (monaural) on the microphone side. Remember to check the battery level using the POWER lamps on the microphone and receiver to prevent recording errors due to dead batteries.
