The MS-MMM-1-MKII professional microphone is a very small, one piece ultra-high gain, ultra-high sensitivity, ultra-low noise microphone that can be plugged into any steno machine, digital recorder or standard computer microphone input jack. The microphone is very small, measuring about 1.25″ long. Included is our best folding tripod. Simply plug the mic into the tripod and you are ready to go!

This microphone is perfect for recording court proceedings, depositions, lectures, business meetings, interviews, music, etc. Is it a great choice for court reporters making a recording with their writer. A high quality, removable windscreen is included with the microphone.

This microphone is very sensitive, with great pickup range. The actual distance will vary, depending on the amplifier power of the recording device, the room acoustics and the loudness of the sounds you are recording:

Ultra-high sensitivity: About 125 foot radius

Sound Quality
This microphone has an extended frequency response and very natural and accurate sound, providing deep, solid bass, smooth midrange and clean highs. Vocals come through clean and crisp.

Information for Court Reporters:

This product is compatible with any Steno machine writer. The following information applies to *any* Steno machine writer. We use the Luminex as an example, only:

The Luminex is a very popular and high quality Steno machine. The manual should be followed as written, however, the following information will help you to achieve the best possible results when recording audio with your writer. The recommendations below are intended as a way of fine-tuning the information found in the manual:

On page 44 of the manual, it states:

Microphone Gain – indicates the current gain setting for the microphone, 0 – 100%. If your microphone is battery powered, set the gain lower. A suggested starting point is 75 – 80%. If the microphone is not battery powered, set the gain higher. A suggested starting point is 95-100%.

These statements assume that battery powered microphones are more sensitive than non-battery powered microphones. This is not always the case. A battery powered microphone could be more sensitive, but merely being battery powered does not mean it is more sensitive (or powerful). An amplified microphone would be more sensitive, but these are extremely rare, and not recommend for devices that have microphone inputs, like the Luminex. In fact, the battery powering a microphone is redundant as the Luminex supplies the necessary power needed for most microphones. This is called microphone “plug in power”.

The microphones we supply to Stenograph for the Luminex do not have batteries and are properly powered by the ‘plug in power’ supplied by the Luminex. In fact, these microphones are more sensitive (powerful) than most battery powered microphones available today. So, they actually require a lower gain setting in the Luminex, not higher. With our ultra-high sensitivity microphones, we recommend a starting microphone gain of 50%

The manual goes on to say:

Setting this gain too high, may cause audio feedback. Press the – and + sensors as necessary to set the percent. A graphic bar indicates the selected level.”

This bar graph is divided into 3 colors – green, yellow and red. It is important to set the gain for the maximum recording level without overloading to get the clearest, strongest recording possible. The ideal recording level is achieved when the sounds you are recording cause the recording level indicator to illuminate the green and yellow segments. The red segments indicate overloading, so it is important that the red segments only illuminate occasionally.

If you hear feedback when monitoring with headphones, simply lower the headphone level until the feedback stops.

On page 43 of the user manual, it states:

Plug the microphone into the microphone jack on the back of the Luminex. Using a direct feed from a videographer to the microphone jack is not recommended since most of those feeds are line level (much higher) and not microphone level.”

If you need to connect a direct feed from a videographer, you can use this cable to reduce the signal down to a safe level that will not overload the mic input on the Luminex.
