Four transmitter microphones

This wireless microphone series features four transmitters: capable of receiving four independent audio signals, suitable for multi-person interviews. Receiver indicator lights are synchronized with the transmitters to avoid confusion and improve recording efficiency for multiple people

The transmitter microphones are equipped with wind shields; placing the wind shield over the built-in microphone can reduce wind noise. The receiver's Type-C connector allows connection to cameras, computers, and other devices, meeting diverse application scenarios 

Indicator lights and screen display

The SVMic D4 lavalier microphone system includes a receiver screen display and transmitter indicator lights for easy viewing of the status of each transmitter and receiver

The wireless transmitter microphone's red light flashes rapidly when the battery is low, a solid blue light is on when connected to a receiver, a solid green light is on when noise cancellation is at level 1, and a solid green and red light indicates level 2 noise cancellation

The receiver's electronic screen displays the connection status with the transmitter, the corresponding transmitter's noise cancellation status, signal strength, battery level, pickup strength, and other information. This makes it convenient to use

Intelligent noise reduction

Employing DSP noise reduction technology, the microphone actively tracks and reduces noise. A 75dB signal-to-noise ratio ensures clear audio output, while a 48kHz sampling rate and 24-bit bit rate preserve audio detail

Physical noise reduction combined with two-stage intelligent noise reduction provides dual noise reduction. The receiver allows volume adjustment; a long press of the volume button switches between output modes (Mono/Ms). Mono is a mixed output, where all transmitter audio is blended across the left and right channels; Ms is a safe audio track output, where the right channel output is 6dB lower than the left channel 

Safe audio track

A backup recording track with lower gain prevents popping sounds, preserves clean sound, and improves recording error tolerance. This avoids ruining an entire recording due to a single recording mistake. In scenarios like large choruses and street performances, where the dynamic range of sound varies greatly, the safety track effectively preserves a wider dynamic range, allowing for more flexible post-production

Single-click the power button on the receiver microphone to turn the low-frequency cutoff function on or off. An icon will appear on the receiver's screen when the function is enabled. When set as a safety track, the receiver screen displays ‘ Ms ’

Wide compatibility

The conference microphone comes with Type-C and Lightning OTG adapters, compatible with cameras featuring a 3.5mm input jack, and offers mono and secure audio track output modes. It can connect to various tablets, mobile phones, computers, cameras, and other electronic devices

Using an adapter, it can be connected to Retekess guided tour transmitters, such as the T130 series and TT129, allowing simultaneous speech from multiple people. It can also be used with the TA003 Silent Disco Transmitter and the TC202 PTZ camera for a richer and more stable creative experience

Multi-scenario applications

This portable microphone ensures clear and stable audio, making it ideal for live streaming, video blogging, on-site interviews, or store visits. Its concealed brand logo design makes it perfect for live streaming, interviews, and meetings

The adapters can connect to a variety of devices, and multiple microphones can meet the needs of meetings, multi-person interviews, and other scenarios. The lavalier microphone is compact and easy to wear; it can be clipped to a collar using a back clip or easily worn using a magnetic clip 

656ft/200m long-distance transmission

This wireless microphone boasts a transmission distance of up to 200 meters in open environments, sufficient to cover large venues and outdoor events. Low latency (20 milliseconds) and noise-canceling technology ensure real-time audio and video synchronization, making live streaming and recording smoother

The transmitter offers 14 hours of battery life, and the receiver offers 6 hours. It automatically shuts down to conserve power after more than five minutes of no signal connection between the transmitter and receiver. This long battery life combined with the long range delivers a satisfying user experience

Long battery life

Say goodbye to frequent charging! The 180mAh transmitter offers up to 14 hours of continuous use, while the 230mAh receiver provides up to 6 hours of battery life. The wireless microphone supports charging while in use, ensuring uninterrupted use without worrying about battery life

Easy to wear

Two wearing options: clip-on or magnetic. The SVMic D4 mini microphone kit (1 to 4) comes with a convenient Oxford cloth carrying bag, combining style and practicality. This durable and lightweight bag provides reliable protection for your device while allowing for easy portability

Operation is simple: a single click of the transmitter microphone's power button toggles the mute function. To pair, turn on the transmitter microphone, press and hold the power button and noise cancellation button simultaneously for 3 seconds until the indicator light flashes rapidly. Then, with the receiver microphone powered on, press and hold the power button and volume button simultaneously for 3 seconds until the signal icon on the display flashes. Wait for the indicator light to stop flashing to complete pairing
