The heart of the transducer is a moving coil, which is allowed to move through a decoupled magnetic field to create a voltage differential, providing an accurate response to the acoustic vibrations of the instrument body. The electrodynamic transducer provides a sound that is unexpectedly "acoustic", with a resulting pickup quality until now thought impossible, close to that of a studio microphone, but without voiceover and with a high resistance to feedback problems.

The DYN series transducers can be used in a variety of situations from home recording to open-air live performances, encompassing all types of music and musical playing styles where the best possible acoustic reproduction is desired. Together with the great sound quality, the simplicity of use makes each DYN series transducer possibly the soundman's best friend.

Another crucial aspect of the reproduction of acoustic sound is the notable difference between studio and live performances. Schertler® acoustic transducers have bridged this gap by providing much more realistic sound reproduction on the stage, more than ever like the studio sound sought after not only by sound engineers and musicians, but by their fans too. This unique dynamic contact microphone technology relegates voiceover to the past and provides far more gain before feedback than other technologies.

The Schertler® name is a guarantee for obtaining the highest performance reliability, as no compromise is made from the engineering of each component, or the material quality, such as Kevlar re-inforced cable, all culminating in a manufacturing process rigorously tested, with guaranteed performance and backed by a two year warranty.

APPLICATION: Use of the DYN series contact microphones is extremely simple and very safe, especially for instruments where the value could be affected by a permanent installation requiring cutting or drilling the wood, or by tacky material which is difficult to remove. The photo shows the correct amount(about the size of a green pea) of Shertler special adhesive putty to be used to mount the pickup on the instrument body. The best location is quickly found through trial and error. The balanced signal out - via the XLR connector - and the low impedance (~ 1500 ohms) reduce the risk of hum and radio frequency interference to a minimum, even when using long cables. The putty leaves no residue, is reusable and is easily removed. To correctly mount the dyn contact microphones, using your thumb, place enough pressure to cause the raised center of the transducer to contact the wood surface.

To remove the transducer, gently twist the transducer left and right and pull. the putty is removed by rolling the putty over the wood surface.

The balanced output also permits direct connection to a mixing board or amplifier input. For amplification devices with direct "line-in", the Acoustic Preamp "PRE-AII" is available for signal boost and modulation. For the very best reproduction of the instrument, Schertler® also offers a series of active acoustic instrument loudspeakers, the PUB Powered Speaker series, offering remarkable clarity and power, and the popular Unico multi-input 180 watt bi-amplified amplifier
