KEY FEATURES

  • 1U metal chassis, equipped with a new VFD screen, monitor headphone jack, a rotary control knob and buttons on the control panel, also, a new AES/EBU digital output and optional Dante or AVB interface on the rear panel. Operation and display mode is consistent with other series.
  • Upgrades the bandwidth to 72 MHz new circuit design for greatly improving the receiving range and increasing interference-free compatible channels.
  • Digital diversity receiving ensures full-range sound quality will not worsen by distance.
  • Proprietary 256-bit encryption prevents unauthorized listening.
  • MIPRO Auto Scan and ACT™ function provides the transmitter’s frequency with precise and rapid sync to the receiver.
  • There are 7 preset groups with a total of 224 pre-saved channels. Group 1 & 2 each allows 16 channels of interference-free operation without any restriction. Group 3 ~ 6 each allows 48 channels of interference-free operation with restriction applied. Group 7 user-defined group allows users to choose and save up to 16 channels from 2,881 available frequencies.
  • Each channel has separate AF signal output and presets the output level equal to the sensitivity of the microphone capsule. Switchable three levels ensure the microphone to operate within proper sensitivity and dynamic range, free from distortion.
  • The proprietary DSP audio processor and A/D converter make the sound quality almost the same as the wired system.
  • The antenna TNC female connectors provide bias for the MIPRO antenna systems to increase the receiving range and improve the signal stability.
  • Optional MIPRO RCS2.Net software allows real-time network remote-controlling and monitoring of up to 64 channels. Additional FSA compatible channels calculator software allows users to manually set compatible channels of any frequency band.
  • External 100~240V AC switching power supply.
  • Designed and made in Taiwan ensures high quality and value.

  • There are two basic types of Wireless Microphones

    Bodypack Transmitters are Used for Lavaliere or “Lapel” Mics, Earset Headworn Mics  and also Instrument Cables

    Lavaliere Microphones, often called “Lapel Mics” or “Clip-On Mics” are a very popular form factor for presenters and public speakers who want the ability to move above with their hands free.

    Lavalieres are excellent for situations requiring “invisible” microphones. These also work well for novice / occasional presenters who are uncomfortable with holding a microphone in their hand or wearing something on their head.

    The  down side to Lavalieres is that they are more prone to feedback and typically provide less signal then a Handheld or Earset.  Having said that – a good sound engineer with the right equipment should have no problem implementing a Lavaliere mic.

    Earset or Microboom Mics

    Earset or MicroBoom microphonesare often referred to as “Countryman Mics” after Carl Countryman , one of the early innovators of the technology - he was also President and Chief Engineer of Countryman & Associates of Menlo Park, California.  These microphones clip to either one ear or both, and typically offer a much better signal that Lavaliere mics simply due to the closer proximity to the speakers mouth.

    Earset mics are excellent for public speaking as well as theatrical performances.  There even models designed to work well for robust singing voices.

    The down side to Earset mics is getting used to something “hanging from your ear”.  There is a tendency to want to reach up and touch it to make sure it is still there correctly.

    Handheld Transmitters are used for the traditional Microphone style.

    Handheld Transmitters provide the most wide-ranging assortment of applications.  The nature and design make them the easiest to use by the “Do it Yourself” person or beginner sound engineer. There are a wide variety Microphone “Elements” available. The element is the end of the microphone, usually round or conical . (in the image above it is silver in color) Different elements work better for different applications.  Handheld Transmitters work best when held directly ion front of the mount or sound hole of the thing being amplified – rather than off to the side or hanging down at the waist.

    Handheld Transmitters are excellent for any application.  They are the easiest to use without feedback, and are very efficient in situations where the microphone will be shared by multiple users (passed around).

    The down side to Handheld Transmitters is that they are bulkier and are not easily concealed.  Also the benefit of the handheld mic can be negated if the person does not hold it in the correct position.,
