1.If using a condenser microphone, flip the Phantom power switch to the “on” position.
If using a dynamic microphone, flip the Phantom power switch to the “off” position.
2.When using the microphone for voice audio, flip the Low Cut switch to “on” to reduce wind and “table rumble” noise.
When using the microphone for music audio, flip the Low Cut switch to “off” to preserve the optimum sound quality.
