The Quantum Blender is our top-of-the-line two-channel preamp/mixer that provides all the control and features you could ever want to combine a piezo transducer with a microphone, magnetic pickup, or another piezo pickup. Channel 1 is switchable between microphone and pickup impedance. This means it can be used with any 2-wire powered lavalier type condenser mic or with a piezo or magnetic pickup. A dynamic mic can be used as well with an appropriate microphone impedance matching transformer. Channel 2 is designed with K&K's Pure pickup in mind, but it works well with most piezo transducers.
