TAFN
COMBO-7000 is an all-in-one PA system which weighs only 11 kg but
packs
more punch than a conventional 4X4 up to 2400W RMS per channel.
It is a single rack system, the only one of its kind in the market
which includes all the usual features of a complete PA system such
as an equaliser,
crossover, limiter and 2 class D stereo amplifier equivalents but in
this case
built into one single unit. It has more than enough
power to suit all possible events and is sometimes twice as powerful
as many conventional system - all in one single unit.

The COMBO has a two stereo power amplifiers
equivalent (four outputsl) system with up to
2400W rms per channel.
Having
class-D amplifiers means it is power and heat
very efficient. Thanks to the new technology
advances, it has a higher damping factor and higher
headroom improving quality sound.
It is controlled by a cross-over where the two mid-high channels are in
the high part of the crossover and the two bass channels are in the low
frequencies of the crossover.
Its internal amplifiers are protected against short circuits, high
frequency harmful oscilations and overload conditions. The
amplifier will limit or cut off according to the hazard that it has to
be protected from. It is protected against every possible hazard so is
unlikely to ever sustain damage.
|
 |
The COMBO also comes with a range of other built-in features. For the
first time, an all-in-one PA unit has the power and features of a bigger
system ideal for pubs, restaurants and small rentals and commercial
events. It's an all-purpose system ideal for almost any situation, with
everything packed into a highly portable, single unit weighing just 11kg
which almost anyone can set up thanks to our clever, easy to use
controls.
VARIABLE EQUAL LOUDNESS CONTOUR
ISO226
|
 |
While a conventional 31 band equaliser
requires professional expertise to use properly,
our equal loudness contour knob is already pre-set to sound as
best as possible to the human ear according to the ISO world
standard, which is ultimately what you want to achieve - but we do
it by emphasising practicality and simplicity.
Our equal loudness contour is the only one in the market which can
be adjusted continuously from flat to maximum contour which will
suit all types of situations.
The key feature is that
you can adjust sound on the fly depending on how you want it to
perform...you can play with the knob easily because
you will always find the right sweet spot.
|
|
Also,
as our hearing does not respond in the same contour between loud
and softer sounds, the fact that it is adjustable makes this the
ideal solution,
especially if you use it in conjunction with other features such
as the bass enhancer and TILT knob to achieve the mix of sounds
that you want. It's all just the turn of a knob or flick of a
switch away. Almost anyone can achieve a
good sound without the complexity of conventional systems. |
|
CROSSOVER
The crossover ranges from 40Hz to 240Hz, which is more than
you need, which means you can make more accurate adjustments. It is
simple to use as everything is controlled by a
single knob, instead of one knob for each channel.
|
LIMITER
This limits the power to keep it within the levels specified from
0 dB to -20 dB. It is very stable and can be managed with a single knob.
It is easy to adjust to the level you don't want sound to exceed.
|
|
TILT
This allows you to adjust the whole sound spectrum in a tilted
angle from the bass up to the treble end of the spectrum with the treble
end being the most affected and the bass the least. This is useful when
you want to emphasize or de-emphasize the high end of the spectrum for
any reason.
|
NOTCH FILTERS
Our notch filters attenuate sound at these particular frequencies
where the human ear is most sensitive: 2.6KHz, the resonant
frequency of the ear canal, and 8.5 KHz, the resonant frequency of the
middle ear. These filters ensure you can listen to loud sound without it
being harsh on the ears. |
ADJUSTABLE
BASS ENHANCER
|
 |
Another
key feature which contributes to the ease of use of the system is that
you can vary the behavior of the bass response by varying the frequency
enhancement while cutting its harmonic which results in a clean, clear
bass in the desired bass profile. This setting is independent of the
equal loudness contour and it can be added on top of all the other
settings to enhance the sound. This setting can also be turned off. |
the MOST ADVANCED
protection system
The
COMBO-7000 contains a full range of protection features to prevent
high-frequency oscillation, short-circuiting, current overloads, sudden
power surges, DC leakage to the speaker, and overheating. We safeguard
against every possible risk, and even offer a soft turn-on feature which
avoids any surge in current when you turn on the amp, allowing many amps
to be turned on at once. For more information about our protection
technology,
see here.
In
the event the amplifier reaches 90 deg C, the amplifier will shut down.
However, before reaching that point, at 80 deg C, the power will drop
slightly, giving the amplifier a chance to cool; once it has cooled, the
power will restore to previous levels, which makes it unlikely the
amplifier will ever reach 90 deg C, ensuring performance is
never interrupted.
