A performing musician is just asking for feedback problems if he or she tries to use an instrument with a built-in mic on stage, particularly if the sound must be amplified a lot.Ĭontact pickups like the K&K mini are much less sensitive to feedback and cause fewer problems in performance situations.Īctive pickups consist of a pickup and a preamp built into an instrument. These pickups seem to be exceptionally well engineered, and combined with a preamp that properly matches the electrical impedance of the pickup, they can perform very well.ĭifferent subject: Microphones in instruments.įor performing musicians, microphones built into instruments are a bad idea.
Like many other pickups, the K&K uses a piezoelectric material as a transducer to change mechanical vibration energy into electrical energy. So, pickups of many shapes and sizes and made of a variety of piezoelectric materials are on the market. There is a wide variety of piezo materials for pickup designers to choose from. Certain inorganic crystals such as quartz or alumina are piezo materials. Piezoelectric materials change mechanical pressure and bending into electrical energy and vice-versa.
The engine in a car can be thought of as being a transducer that changes the chemical energy in gasoline or diesel into mechanical energy of motion. A turbine-generator in a hydroelectric dam is a transducer that changes the energy in water pressure and velocity into electrical energy. A loud speaker is a transducer that changes electrical energy into sound energy.
A microphone is a transducer that changes sound energy (variations in the pressure of air) into electrical energy (variations in voltage and current) You have mentioned that Red-Eye preamps work well with piezoelectric pickups, but how do you find them with transducer pickups like K&k and also something like the anthem where there is a transducer mic? What’s the difference between a transducer and a piezo pickup?Ī “transducer” is any device that can change one form of energy to another.
