One-Touch Frequency Hopping & Smart Channel Selection

In Auto mode, the system powers on and automatically connects while selecting the best available channel. When interference occurs, you can quickly switch frequencies with a single press. Manual mode also supports channel scanning to easily find a more stable wireless channel.

High-Resolution Mini Display

Equipped with a 0.87-inch high-resolution display for clear viewing of audio signal, battery level, pairing mode, EQ settings, and other system information.

Supports One Transmitter to Multiple Receivers

In Manual mode, one transmitter can connect to multiple receivers, making it ideal for band rehearsals, live streaming, interviews, and other multi-user monitoring scenarios.

Plug & Play

The transmitter supports 1/8″ or 1/4″ stereo audio input, making it compatible with audio interfaces, mixers, live-streaming devices, and personal monitoring/mixing systems, with ultra-low latency of just 5.8 ms (with 1.0.3 firmware), 7.5 ms (with 1.0.2 firmware).

Connect a guitar, amp modeler, or audio interface directly, and the C-7 becomes a wireless silent-practice rig.

Button Lock Function

You can double-click the power button to lock the device, so you can stay focused on playing. After the device is locked, double-click the power button to unlock.
