The Comica Vimo C is a 2.4G dual-channel mini wireless microphone system designed for professional audio recording with cameras, phones, and computers. It aims to provide broadcasting-level sound quality in a compact and user-friendly package.
The core function of the Vimo C system is to capture and transmit audio wirelessly from one or two sources to a receiver, which then outputs the audio to a recording device. It operates on the 2.4GHz wireless frequency, offering a working range of up to 200 meters in open areas with a low latency of less than 20ms. The system supports both single-channel and dual-channel operation, allowing for flexible recording scenarios.
Each transmitter (TX) unit is equipped with an internal microphone, eliminating the need for external lavalier microphones in many situations. It features digital signal processing (DSP) to enhance audio quality and includes a one-key noise reduction function to minimize ambient noise, ensuring clear recordings. The transmitters also offer a 4-level adjustable gain control, giving users precise control over input audio levels, and a one-click muting function for quick audio cut-off.
The receiver (RX) unit is responsible for receiving the audio signals from the transmitters and outputting them to the connected recording device. It provides real-time audio monitoring capabilities, allowing users to listen to the audio as it's being recorded. The receiver supports switching between Mono, Stereo, and Safety modes, offering versatility for different recording needs. Stereo mode is ideal for capturing a wider soundstage when using two transmitters, while Safety mode records a backup track at a lower level to prevent clipping.
A key feature of the Vimo C system is its rechargeable storage case, which serves multiple purposes. It not only charges the transmitters and receiver but also provides a convenient and secure way to store them when not in use. The case also monitors the power status of the devices, ensuring they are always ready for action.
The Vimo C is designed for intuitive operation and ease of use. The transmitters and receiver are pre-paired at the factory, allowing for immediate use upon unboxing. If re-pairing is necessary, a simple process involving long-pressing pairing buttons on both the receiver and transmitters facilitates the connection. During pairing, the transmitter indicators blink blue rapidly, turning solid blue once paired, and the receiver's display shows the status of the transmitters.
Installation of the transmitters is straightforward. They are designed to be clipped onto a collar, with the internal microphone pointing towards the sound source for optimal audio capture.
For camera users, the receiver can be easily mounted onto a camera's hot shoe using its belt clip. It then connects to the camera via a 3.5mm TRS-TRS audio cable. When working with mobile phones or computers, the receiver connects using a 3.5mm TRS-TRRS audio cable, and may require an additional audio adapter cable depending on the device.
Monitoring audio is crucial for professional recording, and the Vimo C offers two methods. Users can connect USB-C headphones directly to the receiver's USB-C port for real-time monitoring. Alternatively, a 2-in-1 charging/monitoring adapter cable allows for simultaneous monitoring with 3.5mm headphones and charging the receiver from a power bank or DC power source.
The receiver features a rotatable IPS display, which provides clear visual feedback on various parameters. This includes the receiver's and transmitters' battery levels, signal strength, volume levels for each channel (Transmitter A and Transmitter B), mute status, pairing status, and an audio dynamic bar to visualize audio input levels. The display also indicates the selected audio output mode (Stereo, Mono, or Safety). Volume control for each channel and display rotation are managed through dedicated buttons on the receiver.
The system boasts a long operational duration of up to 20 hours, and the devices support working while charging, which is particularly useful for extended recording sessions. The multifunctional USB-C port on the receiver handles both charging and monitoring, streamlining connectivity.
The Vimo C system incorporates several features to ensure its longevity and reliable performance. The rechargeable storage case is central to this, providing a protected environment for the devices and ensuring they are charged and ready for use. The case's power indicator lights show its remaining power in 25% increments, allowing users to anticipate when it needs recharging.
In the event of an abnormal phenomenon, such as a charging problem, the bat case includes a reset hole. Inserting a reset pin into this hole allows for a quick reset of the case, potentially resolving minor issues.
The transmitters and receiver are designed to automatically turn off when placed in the Bat Case and automatically turn on when removed. This intelligent power management helps conserve battery life and ensures the devices are always ready when needed.
Users are advised to keep the transmitters and receiver face-to-face during operation to maintain optimal 2.4G wireless signal integrity and prevent breakpoints. Protection from rain, moisture, and extreme heat sources is also recommended to safeguard the high-precision components of the product. The inclusion of wind muffs in the accessory list helps in reducing wind noise, contributing to better audio quality and extending the usability of the microphone in various outdoor environments.
