  • Page 7: General Description

    The company’s designs are focused on using sophisticated electronic engineering to achieve the optimum balance of performance and cost. The Explorer 100 Series combines the legendary MICRON qualities of sonic integrity, long-term reliability and rock-solid construction.

  • Page 8: Diversity

    In reflective steel lined rooms such as studios these dead spots happen regularly at wavelength intervals as the transmitter is moved. In the MICRON diversity receiver the combining circuitry automatically rejects the output from the receiving section with the weaker RF signal before it can degrade the audio output. By this means the best signal to noise ratio can be maintained over a large safe operating area.
  • Page 9 Diversity The diagram illustrates how a 2 way diversity system fills in almost all of the dips in received signal strength by utilising the stronger signal at all times.
  • Page 10 Diversity Each SDR Diversity Receiver comprises two receiving sections and a combining unit. The receivers operate on the same frequency with their antennas spaced apart, the comparator automatically rejecting the output from the receiver with the weakest received signal. If signals of similar strength are received the audio outputs are mixed to improve the signal to noise ratio.

    Automatic Gain Control Option The design of the limiter in the MICRON Explorer 100 transmitter enables it to be used as an automatic gain control system, without the pumping effect associated with audio AGC systems. It can also be used as a 'distortionless' limiter, to prevent distortion due to over-modulation.

    Setting the power switch to ‘ON’ position, will switch the receiver ON. (B) Explorer 100 Transmitters Connecting the appropriate standard MICRON audio input lead, or Lavalier Microphone, will switch the TX As the transmitter RF driver stage is stabilized, the output power remains virtually constant as the battery voltage falls.
  • Page 24 For powering through the 4-pin Hirose connector, a combination lead is required e.g. AOCPH-HR4 (B) TRANSMITTERS It is recommended that external power only be applied via a MICRON TLP lead, as this lead includes a 9V voltage regulator and dc filtering. For powering through the 4-pin Hirose connector or the 6-pin Lemo connector a combinational lead is required e.g.TLP07CF-6 or TLP07CF-MHR4...

  • Page 27: How To Get The Best From Explorer

    How to Get the Best from Explorer The level control, in principle, is a peak limiter. Its function is to prevent distortion due to over modulation. Because of the singular design, it can be used as an audio AGC system with great improvement over the 'automatic record' facility of most tape recorders.
  • Page 28 How to Get the Best from Explorer FULLY AUTOMATIC This procedure is for News reporting, interviews and other situations where there is no opportunity for rehearsal with the talent. The objective is to preset the audio gain slightly high and allow the limiter to control the level.
