Rent NowThe Saramonic Blink 900 B2 2-Person Digital Camera-Mount Wireless Omni Lavalier Microphone System (2.4 GHz, Black) is an ultra-compact, dual-channel wireless microphone system designed for videographers, journalists, vloggers, and content creators who need clear, flexible two-person audio capture. The system pairs easily with cameras, smartphones, tablets, and computers, making it a versatile choice for interviews, mobile journalism, streaming, and video conferencing.
Each of the two included clip-on transmitters features a built-in 4mm omnidirectional microphone capsule, letting it function without needing a separate lavalier attached, while still accepting an external lavalier microphone via a 3.5mm TRS mic/line input jack when desired. Audio transmission uses digital 2.4GHz wireless technology, with an auto-scanning RF channel selection and an operating range of up to 656 ft. (200m) line of sight. Each transmitter includes a selectable low-cut filter (160/120/80Hz) and flexible gain control, with audio captured at a 48kHz sample rate and 24-bit resolution, delivering a signal-to-noise ratio greater than 80dB and total harmonic distortion of 0.1% or less.
The dual-channel receiver features a vivid LCD display showing transmitter audio levels, battery life for both the receiver and transmitters, and other key information at a glance, with auto brightness adjustment based on ambient light (manually adjustable across 10 levels). It offers selectable mono or stereo output modes, letting each channel be recorded separately for maximum post-production flexibility, along with a 3.5mm headphone jack for real-time audio monitoring and a separate 3.5mm main output. The system includes four output cables (TRS, TRRS, Lightning, and USB-C) for broad compatibility with cameras, mobile devices, and computers.
Power for the transmitters and receiver comes from built-in rechargeable batteries rated for up to 6 hours of runtime each, charged via a Micro-USB or USB-C connection; an included charging case can provide up to three full charges, extending total usage to approximately 18 hours. The transmitters measure approximately 1.7 x 1.7 x 0.6 in. (43.5 x 43.5 x 16.4mm) and weigh approximately 1.19 oz. (33.6g) each, while the receiver measures approximately 1.8 x 1.8 x 0.6 in. (46 x 46 x 16.4mm) and weighs approximately 1.2 oz. (35.3g).
