  • MPM-3000 with built-in mount

What type of polar pattern does it have?

The MPM-3000 has a standard cardioid pattern that will be the most sensitive directly in the front of the capsule and reject any sound from directly behind the capsule. Here is a graph depicting the capsule's response at 1kHz:

What is the frequency response?

The MPM-3000 has a full 20-20,000Hz frequency response that is fairly flat response with a few dips and peaks in the high-mid range to add color and give it a unique voice. There is a high-peak around 10 kHz to add clarity and air to the sound.

Do I need to use phantom power or a power supply?

The MPM-3000 is a standard condenser microphone and will require 48vDC power, either supplied by phantom power through the interface or mixer, or through an external phantom power supply. Check the specifications for your mixer or audio interface to find out if it can provide phantom power on it's own, or if you will need to supply this through an external adapter.

Here is a simple procedure for connecting the microphone:

  1. Make sure that the gain or volume on your pre-amp, speakers and headphones are all turned down.
  2. Use an XLR cable and attach the female end securely to the MPM-3000. Connect the male end to your microphone pre-amp or phantom power supply.
  3. Once the MPM-3000 is fully connected to the pre-amp, turn on the phantom power.

While disconnecting, always be sure to turn down your pre-amp, speakers, and headphones before turning off phantom power. Wait approximately 30 seconds after turning off phantom power to disconnect the MPM-3000. This can help avoid damage to your equipment.


How do I mount the microphone onto a stand? Do I need a shockmount?

The shock mount is built directly onto the microphone, so there will be no need to attach any additional accessories. When mounting onto your stand, it's important to be cautious and keep a firm grip to avoid dropping the microphone. 

  1. On your microphone stand, loosen the screw that holds the boom arm in place. This is the final arm where you will be attaching the microphone. After loosening the screw, this arm should be able to easily spin in place.
  2. Loosen the screw on the microphone that holds the mounting piece in place and move the mounting piece up so it is perpendicular to the microphone body. Tighten the screw again so that the mounting piece does not swivel on it's own.
  3. Hold the microphone firmly in one hand and bring the mounting piece up to meet the threaded end of the arm on your microphone stand.
  4. Instead of spinning the microphone, continue to hold it in one hand while using the other hand to spin the arm of the microphone stand, screwing it into the microphone's mounting piece.
  5. Once the microphone is securely connected to the arm, make sure the arm on the microphone stand is secure by tightening it's screw.

Important: Always, make sure that the screws on the microphone or stand are loosened before making any adjustments to their angle. Forcing any joint without properly loosening it's screw can damage and strip the joint, affecting it's ability to remain secure. The joints should also never be made too tight and should never require more pressure than can be provided by one hand. Again, this can damage the joint and affect it's ability to remain secure in the future.


The included mount won't fit on my microphone stand. Is it compatible?

The MPM-3000 comes with a thread adapter that may come left inside the microphone mount and can be easy to overlook. This can be used to adapt the microphone to fit on microphone stands with different threading. Most often this is associated with a difference in microphone stands between the US (5/8" threading, without the adapter) and Europe (3/8" threading, with the adapter).

The piece should be easy to screw in and out using a flat head screwdriver, or even just a guitar pick.

Why do I have extra screws and springs?

If one the pieces were missing the microphone would not be able to function as intended, so the extra screws and springs are provided just in case the current ones are lost or worn out.  The screw is used to attach the provided windscreen to the shockmount, and as a small detachable piece, it could easily be dropped and lost. The additional springs are to replace the springs that hold the capsule to the shockmount. If a spring becomes bent or worn out for any reason, it would be beneficial to replace it to retain tension on the capsule and keep it steadily in place.


Which side is the front?

The MPM-3000 is a side-address microphone, meaning the capsule is parallel to it's body. The microphone will accept sound from sources perpendicular to the microphone body, as opposed to a front-address microphone, like the Shure SM58, that accepts sound from it's top or end.

When positioning the MPM-3000, the front will be the side marked by the Marantz logo. Point this side towards your source for the best results.
