Donner CV-2 Wireless XLR Microphone System with 48V Phantom Power

For performers and audio creators who need to use an XLR microphone without a cable running to the sound system, the Donner CV-2 provides a wireless transmitter and receiver for wired microphones.

Its 2.4 GHz connection offers a working range of up to 100 feet, giving you more room to move during a live set, rehearsal, or recording setup.

With support for condenser and dynamic microphones, the CV-2 can also fit into different XLR-based audio setups, from a PA system to a camera or audio interface.

Highlights

The CV-2 is designed to turn a wired XLR microphone into a wireless setup. Connect the transmitter to the microphone and the receiver to compatible XLR equipment, such as an audio mixer, audio interface, PA system, or camera. This can simplify microphone placement on stage or in a rehearsal space, where a cable running across the working area may get in the way.

A 2.4 GHz wireless connection provides a range of up to 100 feet, while support for up to six simultaneous channels makes the system suitable for setups using multiple microphones. Its 24-bit/192kHz audio specification and under-5ms latency support detailed audio capture with a responsive feel for live use. The stated 110 dB signal-to-noise ratio is another relevant specification for customers comparing wireless XLR systems.

The +48V phantom power feature allows the system to work with condenser microphones as well as dynamic models. Double-click to switch phantom power on or off, matching the setting to the microphone being used. The transmitter and receiver have built-in rechargeable batteries, with up to 8 hours of operation, in +48V phantom power mode, the stated battery life is 2 hours.

Tips for day-to-day use

Charge the units before a performance, especially if you plan to use +48V phantom power. The manufacturer advises against charging while the system is in use. For a more consistent wireless connection, keep the transmitter and receiver within range and avoid placing walls or metal objects between them. Nearby Wi-Fi, Bluetooth, or microwave activity can also affect wireless performance, so choosing a clear setup location can help.

Use the supplied XLR cable to connect the receiver to compatible audio equipment, and the USB Type-C cable for charging. When troubleshooting noise, check that the XLR connections are secure, adjust input gain as needed, and check that connected equipment is properly grounded.

Practical tips

For a live stage or rehearsal, connect the transmitter to the microphone and place the receiver at the mixer or PA system. The wireless link can help keep the area around the performer free of a long microphone cable. For recording or video work, the receiver can connect to compatible XLR equipment such as an audio interface or camera.

If your setup uses a condenser microphone, switch on +48V phantom power with a double-click, switch it off when using a microphone that does not require it. The CV-2 is a practical alternative to routing a wired microphone cable across a room when wireless movement is useful, while retaining an XLR connection to the microphone and compatible audio gear.

Is it worth it?

It makes sense if you want to keep using an XLR condenser or dynamic microphone while adding wireless freedom to a performance, rehearsal, or recording setup. The 100-foot range, support for up to six simultaneous channels, rechargeable units, and selectable +48V phantom power bring useful flexibility to XLR-based systems without changing the microphone itself.
