4. Features
- Supports common condenser and dynamic microphones.
- Three output ports for versatile connectivity.
- Low-cut switch for signal attenuation below 80Hz, improving speech intelligibility and reducing microphone pops.
- Maximum amplification gain of 60dB.
- Adjustable treble, mid-range, and low frequencies with a range of ±15dB.
- Overload indicator light to prevent signal clipping.
5. Setup
5.1. Power Connection
- Connect the provided DC power cable to the DC 5V-12V input port on the rear of the MIC-60 unit.
- Connect the other end of the DC cable to a reliable DC5V-12V power source, such as a power bank or a high-quality mobile phone charger. Using a poor quality power supply may introduce AC noise.
5.2. Microphone Input
- Connect your microphone to the MIC IN port on the front panel. This port supports both XLR and 6.5mm (1/4 inch) connections.
- If using a condenser microphone, ensure the +48V phantom power switch is engaged. For dynamic microphones, keep the +48V switch off.
5.3. Audio Output
The MIC-60 offers three output options:
- XLR Output: For balanced audio connection to mixers, audio interfaces, or powered speakers.
- 6.5mm (1/4 inch) Output: For unbalanced audio connection to amplifiers, mixers, or other audio equipment.
- 3.5mm (1/8 inch) Output: For connecting to headphones or consumer-grade audio devices.
Connect the appropriate output port to your desired audio receiving device.

6. Operating Instructions
6.1. Power On/Off
Press the red POWER ON/OFF button on the front panel to turn the unit on or off. The power indicator light will illuminate when the unit is on.
6.2. Gain Adjustment (LEVEL Knob)
The LEVEL knob controls the overall amplification gain of the microphone signal, up to 60dB. Start with the knob at a low setting and gradually increase it to achieve the desired volume without distortion.
6.3. Equalizer Adjustment (HIGH, MID, LOW Knobs)
Use the HIGH, MID, and LOW knobs to adjust the frequency response of your microphone signal. Each band offers a ±15dB adjustment range:
- HIGH: Adjusts the treble frequencies for clarity and brightness.
- MID: Adjusts the mid-range frequencies for vocal presence and instrument body.
- LOW: Adjusts the bass frequencies for warmth and fullness.
6.4. Low-Cut Switch
Engage the LOW-CUT switch to attenuate frequencies below 80Hz. This helps to reduce unwanted low-frequency noise such as rumble, handling noise, or plosives (microphone pops), improving the clarity of speech and vocals.
6.5. Overload Indicator Light
The overload indicator light illuminates when the input signal is too strong, indicating potential clipping or distortion. If this light stays on or blinks frequently, reduce the LEVEL (gain) knob until the light only blinks occasionally or remains off during normal operation.
6.6. +48V Phantom Power
The +48V switch provides phantom power for condenser microphones that require it. Ensure this switch is ON for condenser microphones and OFF for dynamic microphones to prevent damage to dynamic microphones.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use liquid cleaners or abrasive materials.
- Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cable Care: Avoid bending or twisting cables excessively to prevent internal damage.
