For those into serious online voice and video conferencing, Skype, streaming, broadcasting, recording and more; the Marantz Turret Pro broadcast system is a unique Mac compatible peripheral that can consolidate much of your Apple computer AV setup into a single device. An autofocus 1080p driver-free UVC compliant web camera assures instant Mac OSX compatibility and is surrounded by a dimmable ring light. Snap-on filters are included for tweaking the ringlight's 3000K-7000K color temperature range to your liking.
On the audio front, the Marantz Turret broadcaster for Mac also incorporates a high-quality polar-pattern condenser microphone with pop filter. There are onboard controls to activate, mute, and control mic gain. A 1/8"/3.5mm amplified audio out jack for headphones assures realtime monitoring.
The webcam ring light microphone device houses a native Type-C USB-C connection, making it one of the few Mac webcams (like the 4K Logitech Brio) that offers the option of direct USB-C to USB-C connectivity for modern MacBooks, iMacs and Mac minis with Thunderbolt 3/USB-C ports. But it also works on older Mac's with conventional USB ports. There's also two conventional rectangular USB 3.0 Type-A ports integrated into the web camera's base to use as a hub for your other desktop gadgets.
