Brooks RM 909 Inductance
The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys.
Compression Driver
The unit that feeds a sound pressure wave into the throat of a horn (in a horn loudspeaker).
Brooks Hi Fi reviews Electromagnetic Induction or Pick Up
The generation of electrical signal in a conductor moving in a magnetic field or being close to a changing magnetic field.
Insulator
A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.
Brooks RM 909 reviews Keyboard
1) Any musical instrument controlled by pressing a key.
2) The part of the computer that has the keys.
Head
1) In tape recording, the transducer (energy converter) that changes the audio energy from electrical energy to magnetic energy and back; also the devices that apply magnetism to the recording tape for other purposes such as in the erase head.
2) The part of a device that immediately includes the transducer to change sound or audio signals from one energy form to another.
High Hat
A double cymbal on a stand which can be played with a foot pedal or by the top cymbal being hit with a stick.
Ground Lifter
An adapter that takes a three prong power cord and plugs into a two prong outlet, used to disconnect the third (ground) pin of the power outlet. WARNING: It can be VERY DANGEROUS to have no ground connection to the case by using a ground lifter and not grounding the unit by other means.
