  • We strongly recommend that you take a few minutes to read this manual. Indeed, it is important to respect a few principles in order to benefit simply and quickly from these new systems.

What you need to know

  • Always unplug your instrument, or turn the volume down completely before trying a new placement or changing the low cut.
  • This system can operate on phantom power with the XLR.
  • Operation on 9v battery (250H) is activated when connecting a Jack (Output).
  • Unplug it Jack (output) at the end of the session to preserve the 9v battery.
  • In the presence of phantom power, the 9v battery does not wear out.
  • Operate gently to act on the low cut. A small pointed object is needed to operate the switches.
  • The use of the low cut for the aerial microphone is strongly advised in all cases, 360Hz is the default position.
  • This system is like your instrument, it is fragile. Never pull on the cables, always remove the microphone from your instrument gently by taking it by the shell.
  • In the case of using the double-sided to fix the elements of the system, avoid putting your fingers on the sticky part as much as possible. Gently twist the piece to loosen it.
  • For some instruments, adhesive putty is provided to you in order to fix the elements inside a guitar for example or for very fragile varnishes.

Low cut

  • Two small switches are available on the upper surface allowing three positions 180Hz/360Hz/Flat.
  • The two switches on the left cut the bass below 360Hz (maximum cutoff).
  • The 180Hz position is obtained by putting the top switch on the right (the bottom one remains on the left).
  • To have all the bandwidth (Flat), push the bottom switch to the right (the top one stays on the left).

Installation of the aerial microphone

  • Consult the information on installing and positioning the microphone on your instrument in the topics of this knowledge base.
  • The installation of the aerial microphone does not generally pose any problems. You can fix it outdoors with double-sided (supplied) or putty adhesive for very fragile varnishes. The installation inside the instrument can also be done with Velcro.
  • The low cut for the aerial mic should be set to 360Hz by default.
