Important Safety Instructions


Terminals marked with this symbol carry electrical current of sufficient magnitude to constitute risk of electric shock. Use only high-quality professional speaker cables with ¼” TS or twist-locking plugs pre-installed. All other installation or modification should be performed only by qualified personnel.

This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure – voltage that may be sufficient to constitute a risk of shock.

This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual.

To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside. Refer servicing to qualified personnel.

To reduce the risk of fire or electric shock, do not expose this appliance to rain and moisture. The apparatus shall not be exposed to dripping or splashing liquids and no objects filled with liquids, such as vases, shall be placed on the apparatus.

These service instructions are for use by qualified service personnel only. To reduce the risk of electric shock do not perform any servicing other than that contained in the operation instructions. Repairs have to be performed by qualified service personnel.

4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
11. Use only attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/ apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
15. The apparatus shall be connected to a MAINS socket outlet with a protective earthing connection.
16. Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.

17. Correct disposal of this product: This symbol indicates that this product must not be disposed of with household waste, according to the WEEE Directive (2012/19/ EU) and your national law. This product should be taken to a collection center licensed for the recycling of waste electrical and electronic equipment (EEE). The mishandling of this type of waste could have a possible negative impact on the environment and human health due to potentially hazardous substances that are generally associated with EEE. At the same time, your cooperation in the correct disposal of this product will contribute to the efficient use of natural resources. For more information about where you can take your waste equipment for recycling, please contact your local city office, or your household waste collection service.
18. Do not install in a confined space, such as a book case or similar unit.
19. Do not place naked flame sources, such as lighted candles, on the apparatus.
20. Please keep the environmental aspects of battery disposal in mind. Batteries must be disposed-of at a battery collection point.

  1. Use the POWER SUPPLY CONNECTOR to hook up the enclosed power supply unit. Next to this connector you’ll find the strain relief clamp, which prevents accidental release of the power supply.
  2. This is the balanced XLR OUTPUT of your MIC100. Use this connector to feed the XLR input of your mixing console, multitrack recorder or power amp.
  3. The balanced ¼” TRS OUTPUT of your MIC100 can also be connected to either mixer, recording system or power amp.
  4. The balanced ¼” TRS INPUT of your MIC100 can be used to connect your electric guitar, for example. This input is wired parallelly to the XLR input.
  5. Use the balanced XLR INPUT to connect your microphone.
    In contrast to its outputs, the MIC100’s inputs should never be used simultaneously!
  6. The GAIN control allows applying gain from +26 to +60 dB to the input signal. This control should be set fully counterclockwise when (dis)connecting a sound source to the MIC100. When all connections are made, slowly start raising gain.
  7. We recommend using the LED meter to adjust gain. The LED chain displays the output signal level in dB. Please make sure that the clip LED never lights up permanently. It should light up only at peak signals, but never all the time.
  8. If your MIC100 is connected to the mains via the enclosed power supply unit, the POWER LED lights up to indicate that your MIC100 is running.
  9. The 20 dB PAD button reduces the input sensitivity by 20 dB. The appropriate setting depends on the equipment connected. No matter what your application is, the clip LED warns you to reduce the gain setting, so as to avoid distortion.
  10. This +48 V switch activates the phantom power supply for the XLR input. Phantom power supply is required for operating condenser microphones.
  11. With the PHASE REVERSE switch, the input signal is reversed by 180°. This function is available for both mic and line signals. Use this function in a multi-microphone setup if you detect phase cancellations in specifi c frequency bands.
  12. Use the LIMITER switch to limit the signal and to prevent distortion.
  13. The OUTPUT control governs the output level of the device within a range from –∞ to +10 dB. If the control is set fully counter-clockwise, there is no output signal at all. The more the control is set clockwise, the higher the output level.
