The Master Series by Sound Professionals convertible Boundary/Tripod stereo microphones are the best choice for Court Rooms, Depositions, Meetings and Lecture recordings and are hand-crafted in the USA. The MS-MTM-2-MKII - Master Series by The Sound Professionals ultra-high sensitivity microphones offers excellent sound quality and the convenience of removable tripod stands. The stand folds up easily for transport. The microphones will work with most USB soundcards, audio recorders that provide 'plug in power' between 2 and 12 Volts DC at the microphone input jack or with all Steno machines.
This microphones are also perfect for recording lectures, business meetings, interviews, etc. The microphone elements are omnidirectional, so they pick up sound in all directions equally. This microphones have ultra-high sensitivity mic elements for recording sounds ranging from extremely quiet to moderately loud sounds.
The MS-MTM-2-MKII microphones have an extended frequency response and very natural and accurate sound, providing deep, solid bass, smooth midrange and clean highs.
- Flat frequency response
- Can be used directly with any device that provides 2-12vdc plug in power
- Weighs only 2.5 ounces each

Information for Court Reporters:
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.
