If
you are in a Band, or if you organize events, DJ sets or Pianobar and
Karaoke Events, you have probably encountered the "problem" of
amplification.
In
the panorama of Live amplification, however, the offer is very wide and
if you are not particularly skilled you can remain confused in choosing
the most suitable solution for you.
Precisely
for this reason below you will find a mini guide on what are the main
parameters to take into account if you are choosing an amplified speaker
amplification system.
How many Speakers?
Consider
your Live amplification system as a large Hi-Fi system, but it will
amplify the signals that will be heard by more people in a closed or
outdoor venue.
For
this reason the sound front for many, if not the majority of
applications is represented by at least 2 speakers (or multiples)
ideally arranged on 2 columns to create a stereo listening.
If
there is a need then to further extend the range of bass frequencies of
the speakers themselves, usually insufficient in the case of medium or
large spaces, then we would need to add to the configuration of our
system also subwoofers, also amplified in this In
this case, they will try to reproduce only the low frequencies,
guaranteeing an even more qualitative listening and increasing the sound
pressure and the efficiency of our entire system.
What power do I need?
It depends.
It
would seem the most trivial answer but the choice of the power of the
amplification system depends on what we have to amplify and where.
Very
generically we say that the more Watt the amplifier has on board the
speaker, the more sound pressure (SPL) generated by the transduction of
the loudspeaker will be.
Without going into technical detail and for simplicity we divide into 3 macro categories:
Small closed spaces or small outdoor venue - Watts required 50-200W Rms for each speaker (at least 2) - Optional subwoofer
Medium
Closed spaces or Medium outdoor Venue (max 200 people) -
Watts required 200-500W Rms per speaker (at least 2) - Subwoofer
Optional but recommended (of equal power).
Medium-Large
Outdoor Spaces (more than 200 people) - Minimum Watts 500W Rms per
speaker (at least 2) - Subwoofer warmly recommended if not necessary (of
equal power).
How Big (Woofer diameter)?
The
amplified speakers can be found from about 6 "up to 15": with bigger woofer you will have as a result richer response in low frequencies.
Usually by selecting a speaker with woofer gradually larger the level of detail on
the mid-range frequencies becomes smaller: this depends by characteristics of the speaker and the components that are
mounted in it.
For
a DJ set, for example, or to amplify a complete Band, we recommend the
15 ", especially if we do not have a subwoofer, for a speaker vocal-oriented or to amplify acoustic
instruments recommended 10" or 12 ".
If we want our speakers to match a subwoofer we consider that the offer starts from about a 12 "up to 21".
In
this case it is preferable to select a SUB with a slightly larger
Woofer than our speakers for tonal reasons: if we have for example a pair
of 10 "speakers, it is better to add a Subwoofer with at least 12" or
even better with a 15 " , with a pair of 15 " satellites an 18" sub is preferable.
Alternative solutions?
Other solutions are represented by compact PA systems.
Among
these the compact vertical arrays, for example from RCF, FBT,
MONTARBO, PROEL, TOPP PRO and others, are certainly interesting: they
not only combine high-quality tone but guarantee high transportability
and low weight.
The
proposed structure consist of a Mini Array SUB + SATELLITE with features from the large arrays used for example in
large stadium concerts where the effectiveness of the system is
guaranteed even for single speakers not necessarily large (like for the speakers mentioned above).
For Special Requirements ...
In
this section you will also find amplified Battery Speakers for use even
without the mains, Speaker with built-in media player, Speaker with
included radio microphone kit and also Speakers equipped with LEDs to
illuminate the performance.
