Brooks RM 909 Chamber

1) An Echo Chamber (a room designed with very hard, non-parallel surfaces equipped with a speaker and microphone so that when dry signals from the console are fed to the speaker, the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console).
2) A program in a delay/reverb effects device that simulates the sound of an Echo Chamber.

Layering

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.

Frequency
The number of cycles of a waveform occurring in a second.

Filter
1) A device that removes signals with frequencies above or below a certain point called the cut-off frequency.
2) An equalizer section, used in this sense because filters are used with other components to give an equalizer its frequency response characteristics.
3) The action of removing signals of some frequencies and leaving the rest.
4) A mechanical device to smooth out speed variations in tape machines called a Scrape Flutter Filter- more usually called a Scrape Flutter Idler

Brooks RM 909 reviews Diaphragm
A thin flexible membrane or cone that vibrates in response to electrical signals to produce sound waves. Distortion is usually referred to in terms of total harmonic distortion (THD) which is the percentage of unwanted harmonics of the drive signal present with the wanted signal. Generally used to mean any unwanted change introduced by the device under question.

Chip
1) A slang term with the same meaning as the term IC (a miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).

Magnetic energy put out because of current travelling through a conductor.

Barrier Micing
A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation.

Balance
1) The relative level of two or more instruments in a mix, or the relative level of audio signals in the channels of a stereo recording. 2) To make the relative levels of audio signals in the channels of a stereo recording even.
