BNO Acoustics QT-5 Line Level

1) An amplified signal level put out by an amplifier and used as the normal level that runs through the interconnecting cables in a control room.
2) A low level signal such as the signal in a guitar cord. Most parts of a PA require a line level signal. Remember, however, that speaker outputs are not line level. Plugging speaker outs into line ins will result in damage to the equipment

Impedance
1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms).
2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value.
3) The opposition to alternating current.

BNO Acoustics HD-70 Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

House Sync
A synchronization signal such as SMPTE time code that is used by all recorders in the control room.

BNO Acoustics R-10 Speakers ADAT
A trademark of Alesis Corporation designating its modular digital multitrack recording system released in early 1993.

Analog (Analogue)
Representative, continuous changes that relate to another quantity that has a continuous change.

Flamenco
A style of music with roots in Spanish and Arabic culture.

Cut-Off Frequency (Turnover Frequency)
1) The highest or lowest frequency in the pass band of a filter.
2) The highest or lowest frequency passed by an audio device (the cut-off frequency is usually considered to be the first frequency to be 3 dB lower than a reference frequency in the middle of the bandwidth of the device)
