BNO Acoustics BP-40 Frets

Vertical metal wires which sit vertically on the guitar neck.

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.

BNO Acoustics GT-60 BPM
An abbreviation of Beat Per Minute (the number of steady even pulses in music occurring in one minute and therefore defining the tempo).

Floppy Disk (Floppy Disc)
A round flat object (usually housed in a protective sleeve) coated with material that can be magnetized in a similar manner to tape.

BNO Acoustics HD-70 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.

Arc
The visible sparks generated by an electrical discharge.

Electricity
Electrical current (the amount of electron charge passing a point in a conductor per unit of time) or voltage (the force pushing electrons to obtain electrical current).

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.
