DYN-Series Electrodynamic Contact Transducers
The acoustic electrodynamic transducer from Schertler is patented worldwide. The heart of the transducer is a coil which moves through a decoupled magnetic field to create a voltage differential, delivering a true response to the acoustic vibrations of the instrument’s body. Schertler DYN-Series transducers provide a sound that is exceptionally “acoustic” in nature. The sound is close to that of a studio microphone, but without the on-stage problems of bleed or feedback.
DYN-Series transducers can be used in a variety of applications, from home recording to live performances. DYN-Series transducers have a low-impedance, balanced XLR output. Easy to install, they provide extremely fast response to instrument vibrations as well as accurate reproduction of the instrument’s characteristics, allowing a wide variety of instruments to work in close proximity. With Schertler DYN-Series transducers, isolation is no longer a problem, providing a solution to eliminate bleed and feedback on stage, and permitting maximum flexibility in stage layout and use of available space,
Feedback
Schertler DYN-Series transducers deliver “microphone-quality” sound with significant resistance to feedback. (Of course, ANY acoustic instrument, given its light frame, will eventually resonate in response to very loud speaker output).
Applying the Electrodynamic Transducer
The application and use of Schertler DYN-Series transducers is extremely simple and safe. Special inert adhesive putty is provided to mount the pickup to the instrument body. The best location for your sound is quickly found through our indications or through experimentation with placement.
The balanced, low impedance output reduces the risk of hum and radio frequency (RF) interference, even with long cable runs. The XLR connector allows direct connection to mixing desks or preamplifier inputs. For additional control of level and tone, the Schertler PRE-AII preamplifier is perfectly matched to the DYN-Series.
DYN-Series transducers are expressly designed for mandolin, violin, viola, cello, double bass, guitar, harp, piano (including grand piano) and many ethnic or “world” instruments.
The DYN-Series by Schertler allows musicians total freedom of movement while isolating the instrument from surrounding signals. There can be two people on stage, or twenty, and DYN-Series transducers will deliver needed headroom and dynamics.
DYN-B
Schertler's DYN-B transducer is tailored specifically for double bass. The Schertler® Double Bass DYN-B transducer through neutral amplification guarantees a true reproduction of double bass.The quality of a studio microphone, but without feedback. The response, the dynamics, the entire feel of the sound, can no longer be distinguished from a purely acoustic performance. A pre-condition for perfect acoustic performance is a neutral amplification system - To control feedback tendencies there is an integrated phase inversion circuit within the transducer's XLR connector(to suppress standing waves). In addition, the instrument resonance filter of the optional Schertler®Acoustic Pre-Amp "PRE-AII" helps to counter any tendency of the double bass to resonate with the loudspeaker. The use of the PRE-AII is generally recommended for bass players, since this by itself provides a line-out signal for additional system components to perform whatever modulation is required.
