   • For Condenser Microphones: Connect your condenser microphone to the XLR combination socket on the front panel. After connecting, switch the +48V Power Switch to the ON position to provide phantom power.
3. Output Connection: Connect one of the MIC OUT ports (XLR, 6.35mm, or 3.5mm) on the rear panel to your audio interface, mixer, console, or powered speakers using an appropriate audio cable.
4. Power On: Press the POWER ON/OFF button on the front panel to turn on the MIC-60. The power indicator light will illuminate.
5. Initial Settings: Before speaking into the microphone, set the Gain Adjustment Knob and Output Volume Knob to their minimum positions to avoid sudden loud sounds.

7. Operating Instructions

1. Adjusting Gain: Slowly increase the Gain Adjustment Knob until you achieve a suitable input level. Monitor your audio interface or mixer for optimal signal strength without clipping.
2. Adjusting Tone: Use the Bass, Midrange, and Treble knobs to fine-tune the microphone's tonal characteristics to your preference or the requirements of your recording/performance. Adjust these incrementally.
3. Adjusting Output Volume: Once the input gain and tone are set, use the Output Volume Knob to control the overall signal level sent to your connected audio device.
4. Monitoring: Always monitor your audio through headphones or speakers connected to your audio interface/mixer to ensure the sound quality is as desired.
5. Phantom Power Usage: Only activate the +48V Power Switch when using condenser microphones that require phantom power. Ensure it is off for dynamic microphones to prevent potential damage.
