BBE
Mach3Bass electronically extends the bass response of a given loudspeaker
and is capable of precise tuning at the specific low-end frequency desired.
Assisted by the phase error correction technology of the world-renowned
BBE process, BBE Mach3Bass provides deeper, tighter and more musically
accurate bass frequencies than standard bass boost circuits. BBE Mach3Bass
does not affect the mid-to-low range of the sound which, if altered, creates
muddiness in the mid-low frequency range and also changes the character
of voices.
The Mach3Bass
process works by boosting a particular low frequency using a constant
Q band pass at an optimized level. As a result, Mach3Bass processing provides
acoustic output characteristics similar to bass reflex port tuning of
a low frequency loudspeaker's enclosure. Mach3Bass does this electronically
and more efficiently than port tuning, while protecting the loudspeaker
from unnecessary cone excursion at very low frequencies.
BBE Mach3Bass
is available to BBE consumer electronic licensees in both analog and digital
solutions. BBE Mach3Bass has been successfully in use since 1999 in premium
products from consumer electronics manufacturers including Sanyo and Sharp.
The latest digital Mach3Bass extends the same benefits to digital products
and is suitable for television, home audio / video, portable audio, car
audio, headphone stereo and multimedia computer use.
Mach3Bass
has powerful advantages over typical bass boost technologies:
u |
Musical
sounding - Mach3Bass does not affect mid-low frequencies, so the mid-low range
remains clean and without the exaggerated "over boosted"
sound typical of other bass boost technologies. |
| |
|
| |
|
u |
Tight
and punchy bass- Mach3Bass never sounds "boomy"
or "mushy". |
| |
|
| |
|
u |
Vocals
unaltered - the timbre and overall character of human voices
is unchanged by Mach3Bass. |
| |
|
| |
|
u |
Loudspeaker
output efficiency - Mach3Bass allows the loudspeaker to maximize low frequency output
by economizing cone motion. The loudspeaker wastes no effort in attempting
to produce frequencies below the audible low frequency range. |
| |
|
| |
|
u |
Loudspeaker mechanical efficiency - since the low frequency loudspeaker is not burdened with excessive
cone movement, the voice coil generates less heat and cone surrounds
are subjected to less wear. |
| |
|
| |
|
u |
Amplifier
efficiency - Mach3Bass maximizes low frequency output while
minimizing the power requirement of the amplifier. |
| |
|
| |
|
u |
Deeper
bass - Mach3Bass technology allows the loudspeaker
to safely reproduce deeper bass, without risk of damaging the loudspeaker. |
Mach3Bass applications are wide-ranging:
