ClearOne announced DIALOG 20 USB microphone for hybrid meetings that require a dedicated presenter microphone and a shared audience microphone with simultaneous sound reinforcement, such as any type of hybrid training or presentation session. The DIALOG 20 USB works in spaces up to 2500 square feet. ClearOne says there are lower cost two-channel wireless microphones on the market, but the microphones can’t effectively be used for local sound reinforcement either due to high latency that causes a presenter to hear a delayed echo of their voice when the output from these low-cost systems is amplified into the local room, or due to low audio quality. ClearOne says the DIALOG 20 USB solves these problems due to its low-latency design and full bandwidth professional audio quality.

Featuring a complete range of handheld, boundary and gooseneck microphone options, as well as a beltpack with lanyard, headset, or lavalier mics, ClearOne says the DIALOG 20 USB is powered by frequency-hopping spread-spectrum technology with no frequency license restrictions world-wide. A built-in auto-scan feature automatically finds open channels for optimal reception. Standards-based encryption ensures a secure link for wireless audio, and wide audio bandwidth provides superior speech clarity.

The company says the DIALOG 20 USB wireless microphone is a “breeze” to set up. It connects to a PC via a single USB Type C cable for audio, power and control, which ClearOne says eliminates the need for an external power source or any additional audio cables. Easy to install and manage through the system’s full-featured software, DIALOG 20 USB also comes pre-integrated with P-Link native connectivity for power, audio and control data with ClearOne’s CONVERGE Pro 2 DSP mixers. Industry-standard connections include USB-C audio, professional XLR and 1/4-inch TRS balanced audio outputs. The company says USB connectivity and low latency make this the “perfect” wireless microphone for cloud-based collaboration with Microsoft Teams, Zoom, WebEx, GoToMeeting and others.

ClearOne says the receiver has a large color LCD for viewing battery life, received signal strength and programmable microphone ID labeling. Sync the microphones to the receiver with a button press and the system will assign a random encryption key, scan the room for interference and select the best RF frequencies to operate automatically, according to the company. Microphones can be powered with the included environmentally-friendly rechargeable NiMH AA batteries – charge via USB – or off-the-shelf AA alkaline batteries.
