Brooks Hi Fi speakers Input Overload

Sending too high of a signal level into a device so that the first amplifier of the device overloads.

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.

Brooks Hi Fi reviews Ground Loop
A double grounding of a line or electronic device at two different "ground" points of differing voltage.

Limiter
A device which reduces gain when the input voltage exceeds a certain level.

Brooks HI FI projectors Capacitance
That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.

Amplifier
A device which increases the amplitude (level) of an electrical signal (making it louder).

Bass Roll Off
An electrical network built into some microphones to reduce the amount of output at bass frequencies when close-micing.

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)
