B
Back-up Battery An optional
option for security system where as a
separate battery system is added to the
existing power supply to serve as a backup
if the vehicle's battery should be
disconnected.
Balance A feature that will
control the volume output to the left or
right speakers to allow the proper volume to
balance in the center of the listener.
Bandpass A filter that cuts both
low and high frequencies enabling a band of
frequencies between these two points to pass
through a given point.
Bandwidth A range of frequency
response between upper and lower frequencies
points in which audio signals pass through
an electrical device and where the audio
signal has rolled off by the rate of three
decibels.
Barium Ferrite - A magnet made from
alloy with barium and iron plates sandwiched
between a magnet to improve magnetic
strength
Basket - The metal frame of a
speaker motor that supports all of it's
components.
Bass - Low audio frequency range
produce in an audio output below 500 Hz.
Bass Reflex System Typically a
vented enclosure that allows control of the
rear radiated sound waves of an enclosure.
Battery - A group of electrically
charged cells wired in series that stores an
electrical energy. Converts chemical energy
to electrical energy.
BBE Processing - A signal
processing circuit that provides imaging and
spatial realism by altering the frequency
and phase characteristics of a specific part
of the input signal.
Bi-Amplification - The use of
multiple amplifiers, to amplify more than
one frequency. such as lower bass, treble,
midrange and all other frequencies. Each
amplifier is dedicated to each frequency.
Bias - A high frequency current
applied to the tape head along with the
audio signal to increase sensitivity and
prevent distortion during the recording
process.
BL - The strength of a magnetic
force a motor structure possesses. "Or
called Tesla meters, this measurement of the
motor strength of a speaker.
Boom - Excessive bass response or
peak of a recording, playback, or audio
system.
Boost - To Increase a specified
signal.
Bottom End - Refers to the sound
qualities of the lowest frequency ranges of
an audio systems speaker. or also known as
bass response.
Bridging The processes of
electricity combining both outputs of an
amplifier to be as one, . This increases the
power output (wattage) by 2. If the
amplifier is 50 watts per channel bridging
will generate 100wats of power..
BTL - Bridged, Transformer Less. A
circuit that contains two Integrated Circuit
(IC) amplifier channels and are bridged
together providing a single, larger output
circuit.
BTM - Best Tuning Memory. A feature
that selects radio stations by the strength
of its signal, and programs them to the
radio stations preset buttons.
Buffer - This device protects
against vibrations by storing the audio
information for uninterrupted playback. Data
is available from the buffer when it can not
be read from the disc as long as the reading
the disc does not exceed the playback time
of the audio stored in the circuit |
