Ideal for broadcasters, podcasters, vloggers, livestreamers, YouTube creators and filmmakers. This incredibly portable and featherweight kit comes with a single clip-on wireless transmitter with a built-in mic, a pro-grade lavalier microphone, a device-mountable dual-channel receiver and a portable charging carry case. The receiver mounts directly to the Lightning port of your iPhone or iPad, providing a digital connection right to the iOS Device. It is so compact and lightweight; you can add fully functional wireless system to your iPhone or iPad, without any mounting accessories or adding significant weight. Letting you easily mic yourself or someone else, and if you ever need to put mics on two people, you can simply add a second Blink 500 Pro TX wireless transmitter (sold separately) and make it a 2-person wireless system.

Truly Professional, Next Generation 2.4 GHz Wireless System

The Blink 500 Pro B3 is the next generation of the immensely successful Blink 500 system. Combining the revolutionary design, ease of use and industry leading flexibility of the original system with an updated design, headphone output, OLED displays, longer battery life, expanded range, elevated sound quality and an impressive list of new pro features that set it apart from the original Blink 500 system and competitors. While still being remarkably easy to use. So, you can literally just turn it on and start recording.

For iPhone and iPad with Lightning

The Blink 500 Pro B3 system’s RXDi Pro dual-channel receiver plugs right in and mounts to the iOS device’s Lightning port. Allowing the system to work perfectly with your iPhone or iPad. A 3.5mm headphone output lets you monitor the sound in real-time, even if your app does not allow real-time monitoring. Absolutely vital to ensure you’re getting the best sound when recording and finally allowing you to hear the other participants in virtual meetings, video calls and virtual classroom applications in real-time. The RXDi Pro also features a much-desired selectable Mono / Stereo output setting, giving you the ability record each mic to separate channels of iOS device’s video or audio recording app, when using an additional TX transmitter (sold separately).

The Tiny, but Mighty TX Transmitter

The Blink 500 Pro TX transmitter is ridiculously compact and lightweight, yet it delivers high-quality professional sound, anyway you want to use it. It features a built-in omnidirectional microphone with an impressive sensitivity of -39dB. Giving you dynamic, crystal-clear sound quality on a transmitter that you can easily clip to a shirt, collar or slide into a pocket, yet versatile enough to set on a table or podium. The TX transmitter also operates as a traditional bodypack transmitter with the included SR-M1 professional omnidirectional lavalier microphone, providing an even more visually discreet miking solution. It can also be used handheld, by itself or with the optional Blink500 Pro HM Handheld Mic Holder (sold separately).

Mic or Line, It’s All Fine

As an added unique and amazing feature, the Blink 500 Pro TX transmitter also allows you to transmit microphone-level or line-level signal wirelessly and provides plug-in power to microphones. This makes the system tremendously versatile allowing you to connect it to virtually any audio source. You can use the included SR-M1 lavalier or plug in a mini-shotgun microphone, you can add a headset microphone, or a higher-end lavalier. Just about any 3.5mm microphone wired for standard TRS pin-out will work, and the adjustable mic gain lets you get perfect levels every time. Switch the TX transmitter to line-level and connect it to mixers, music players, or any line-level device output you want to transmit wirelessly to the receiver.

Unmatched Power and Range, Paired with Sophisticated Simplicity

The Blink 500 Pro B3 takes power and range to a higher level. With an expanded range of up to 328-feet (100m) and the expanded transmitter battery life of up to 8-hours, users now have the freedom for wider, more expansive shots without fear of dropouts and have the ability to shoot for an entire day on one charge. The included charging carry case provides vital protection for storage and transit, but also provides a rechargeable 2000mAh internal battery allowing you to charge your system anywhere. Perfect for creators that are always on the go, to never be without power to charge. You can even pair it with a USB power bank, for remote charging when filming on location. Lastly, with revolutionary one-touch pairing built into the charging case, you can sync the Transmitter and Receiver with ease without fumbling through menus, searching through channels, or even removing from the case.

A Remarkable Wireless System

The Blink 500 Pro B3 is the most feature packed, ultra-compact 2.4GHz wireless system for iOS devices on the market today. It offers innovative features, performance and flexibility that drastically set it apart from competition while delivering crystal-clear professional sound. Making it ideal for demanding content creators, professionals and pro level consumers that need an advanced, yet incredibly easy-to-use wireless system for their Lightning iOS device that won’t slow them down. Small enough to put in a small bag, or backpack, so you can effortlessly bring it with you everywhere you go, and you can count on it being charged up when you get there. The Blink 500 Pro B3 system is also perfect for users who only need one wireless mic right now but want the ability to expand and use two in the future.
