- I -
Input - 1) The jack or physical location of where a device receives a signal. 2) The signal being received by a device. 3) The action of receiving a signal by a device.
Input Impedence - The opposition to current flow by the first circuits of a device.
Input Monitor - A switch position and operational mode of the electronics of a tape machine where the signal at dtitput of the electronics will be the same as the signal coming into the electronics. rn this mode, the tape machine's meter will read the input signal.
Input/Output Module - A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections.
Input Overload - Sending too high of a signal level into a device so that the first amplifler of the device overloads.
Insert - 1) A punch in of the all of the tracks being recorded in a recording session. 2) On Solid State Logic consoles, placing an outboard piece of gear in the channel by patching and activating a switch.
Instrument Amplifier - A device that has a power amplifier and speaker in a case (or in separate cases) to reproduce the signal put out by an electric instrument (such as an electric guitar) and to allow the instrument to be heard.
Instrument Out Direct - Feeding the output of an electric instrument (like an electric guitar) to the recording console or tape recorder without using a microphone.
Insulator - A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.
Integrated Circuit (IC) - A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.
Interface - Any device that allows one unit to work, drive or communicate with another unit when they cannot do so by just feeding each other often because the units are manufacturcd by different companies.
I/O - Short for "Input/Output' and referring to: 1) An in-line console module that contains controls for the input section, output section and monitor section. 2) A module in electronic gear containing input and output amplifiers for the device. 3) A digital port (connector) able to both receive digital data and output digital data. 4) A card or separate unit that converts audio to digital audio for input into a digital system and also do the reverse for the output.
Isolation - A containing of the sound wave in a certain area so that it will not leak into other areas and/or unintended mics.
Isolation Booth/Isolation Room - A room that prevents loud sounds from other instruments from leaking in: an isolation booth is usually a smaller room that could be used for ouly one musician.
