-7%
The Ulanzi A30 Tiny wireless lavalier microphone system includes 2 transmitters and a USB-C receiver for recording audio on a phone, camera or computer. Supplied Lightning and 3.5 mm TRS adapters provide additional connection options.
Audio recording and transmission
The omnidirectional microphones capture sound from all directions at 48 kHz / 16-bit. Noise reduction helps reduce unwanted background sound, while real-time monitoring lets you check audio during recording. Transmission uses the 2.4 GHz band, with a range of up to 50 m unobstructed or up to 30 m with obstacles.
Mounting and battery life
- Two mounting options: attach the 11 g transmitters to clothing with a clip or magnetic holder.
- Charging: the transmitters run for up to 5 hours per charge, while the 1000 mAh case provides another 20 hours of operation. The microphones can also charge during use.
- Customisable appearance: interchangeable black and white housings and stickers let you change the microphones' look.
Windshields and a transport bag are also included. Charge-level indicators help you keep track of remaining power.
