  • The model 2X48 + ACPJ is a system with a remote preamp that works on 9v battery (250 hours) or on phantom power (automatically). It receives the signal from the two microphones via a cable Jack stereo, has a volume control per channel and independent outputs in Jack and XLR, its microphone kit is removable and adapts to many instruments ... It is equipped with the miniature aerial microphone Ischell A1 allowing you to get as close as possible to the sound source, recognized for its quality and linearity, and secondly the new type of contact microphone C1 developed by the brand ISCHELL in 2008, or currently the C2 or the C3, in order to reproduce with the greatest fidelity the acoustics of your instrument, the attack, the timbre, the woody color, your playing and your playing nuances, without the problems of feedback and recovery of surrounding sounds. Our hybrid Air / Contact technology works without a filter between the membrane and the soundboard of your instrument. We thus reproduce on a reduced and isolated scale an aerial sound recording controlled by the immediate environment of our specific putty audio adhesive. A revolution in the amplification of many instruments on stage, an innovation ISCHELL !
  • All our products are manufactured and assembled in France by hand, with awareness and respect for a job well done, only with high quality components, for products that we hope will bring you satisfaction for many years on stage, in the studio and at each of your performances amplified.
  • 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 before attempting placement again or changing the low cut.
  • Wash your hands before kneading the putty and carefully clean the bonding areas before doing your tests, they must be clean, dry, non-greasy and smooth.
  • This system operates on phantom power with XLRs.
  • You must use a Jack stereo connection between the microphone kit and the pre-amp.
  • Operation on 9v battery (250H) is activated when connecting a Jack (Output).
  • Unplug them Jack (output) at the end of the session to preserve the 9v battery.
  • In the presence of phantom power, the battery does not wear out.
  • The contact microphone corresponds to MIC 1 and the aerial to MIC 2
  • 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.
  • The contact microphone is generally delivered to you in the 360Hz position depending on the instruments. However, if after finding the best positioning, you lack breadth in the bass, then try 180Hz (Middle Position) or Flat (Full Bandwidth). Additional information will be given to you in the “installation on your instrument” section of this knowledge base.
  • Your system comes with two types of audio adhesive putty for the contact microphone. A white and a gray, they do not have the same sound. The white putty has a clear sound, use it to start your tests, if after having defined the best placement for the microphone, the sound remains too bright, then try the gray for a duller sound in the highs and rounder in the highs. bass. The gray putty is particularly suitable for instruments wishing a dull sound as well as for quartet instruments.
  • Carefully read the instructions for preparing the various contact microphones and those concerning the positioning on your instrument, in this knowledge base.
  • Original C1 contact microphone preparation page
  • C2 and C3 contact microphones preparation page
  • Use only the audio adhesive putty ISCHELL ! Any other putty will distort the quality of the sound.
  • This system is like your instrument, it is fragile. Never pull on the cables, always remove the contact microphone delicately from your instrument, taking it by the shell and gently tilting it while removing the putty to avoid a too sudden suction effect (fragile membrane) and to preserve the surface of the instrument.
  • 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.

Low cut

 

  • Two small switches are available on the upper surface allowing three 180Hz / 360Hz / Flat positions.
  • 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.
