Super Cardioid Dual-Channel Wireless Shotgun Microphone
The shotgun microphone innovatively integrates a wireless RF module to support wireless transmission and single/dual channel options,providing a more flexible solution for professional recording. 14mm gold-plated mic capsule adopts super cardioid polar pattern to accurately pick up original sound and avoid the surrounding noise, presenting fuller, brighter, and crisper high-fidelity sound quality.
The industry's advanced 48kHz/32-bit float recording provides extremely high audio quality and dynamic range that supports lossless audioadjustment in post-production, which meets the needs of high-sensitivity audio production, such as music production, film dubbing,professional interviews, and broadcasting. The wired and wireless transmissions are available in sync to support multiple devices' output.
Built-in 32GB storage can store up to 40 hours of uncompressed audio. Users can back up the audio during shooting and recording,or use the microphone as a recorder. It ensures audio integrality, making creation more secure.
Official Comica Audio App has iOS and Android versions that can connect to VM40 via smartphone Bluetooth. Users can operate the shotgunmicrophone and receiver through the App. It supports remote monitoring of microphone status, changing settings, managing multiple devices by scene, etc
CalMix® denoise precisely reduces background noise and improves audio quality. The low-cut function filters the audio below 100Hz in the microphonesignal to reduce low-frequency noise. The high-frequency boost enhance the high-frequency part of the microphone signal to make the sound clearer and brighter.
Both of the shotgun microphone and receiver support USB-C digital output and 3.5mm TRS/TRRSanalog output, which is widely compatible with cameras, smartphones, computers, etc.
The shotgun microphone supports automatically power on/off when connecting/disconnecting the output device, which is plug-and-playand power-saving. Both of the shotgun microphone and receiver supports auto-sensing TRS/TRRS plug to output analog audio.
Mono mode is suitable for basic recording. Stereo mode can capture the sound details and present a richer sound effect. Safety mode providesa -6dB backup to avoid popping sounds. Real-time monitoring provides instant feedback on recording effects for better adjustment.
Both of the transmitter and the receiver has a high-definition screen to display battery power, wireless status,audio dynamics, channel mode, gain level, etc, providing users with intuitive data feedback during recording.
VM40 supports long battery life and charging while using. In wired mode, it lasts up to 32 hours. In wireless mode,it lasts up to 10 hours. Users can focus on creation without worrying about battery power.
The wireless transmission distance is up to 200m in an open area and is stable without dropouts.Less than 20ms latency makes the audio transmission high efficient and synchronized with the video.
The shock mount reduces or eliminates the noise caused by vibration and collision to ensure the quality of recording.The equipped high-density windscreen and wind muff effectively filter various noises and ensure clear reception even when shooting outdoors.
