General Introduction

The CU58 is a USB microphone with a cardioid polar pattern. It features a monitor mix control switch, headphone volume control switch, mic gain adjustable switch, and a mic mute knob. These controls make the microphone more practical. It is a plug-and-play USB device, compatible with Windows and MAC computers. A purple LED inside the microphone cage indicates when the microphone has power. Its special mount shock reduces vibration during recording and stage performance.

Introduction of Each Button

The CU58 microphone features several controls:

• 1. MUTE: Press this button to mute the microphone.
• 2. MIC GAIN: Adjusts the microphone's sensitivity.
• 3. MIC/USB: Mixes the microphone signal with the sound from your audio recording software. Turning the knob counter-clockwise increases the microphone signal and decreases the computer/device software signal. Turning it clockwise increases the computer/device software signal and decreases the microphone signal. (It is recommended to keep this knob in the center position for an equal balance of both signals.)
• 4. VOLUME: Adjusts headphone volume.
• 5. Headphone Connector: Standard 3.5mm stereo headphone connector.

The microphone has a purple LED indicator that lights up when powered.
