Andrew Grayland and John Austin former R&D manager and one
of the Technical Directors of Klark Teknik started XTA in 1992.
Having overseen many of the benchmark products produced by KT,
both Andrew and John felt that DSP (digital signal processing)
technology could find a home at the heart of PA systems. At this
time DSP was often disregarded because of its audio quality, but
Andrew and John felt with the right algorithms and using 32-bit
processing coefficients instead of 24-bit - what the majority
of DSP designs were using - digital equipment could be designed
that would sound very pure and clear.

The first product to ship bearing the XTA name was the DS400 mic
splitter, followed by the RT1 and GQ600. This gave Andrew and
John the time to develop the DP100 digital delay unit, which incorporated
three bands of parametric EQ on each of its four outputs. The
units quickly found a large fan-base, and demands for more EQ
and control led to the DP200. The DP200 gave users access to EQ
control not only on the outputs but also on the inputs, along
with high and low pass filters using the first version of XTA’s
remote control software, AudioCore. Although designed largely
for instillation use, the DP200 found its way on to the touring
circuit due to the high sound quality and flexibility that the
digital control brought.

To deal with the increased demands of the touring market the DP226
was launched in 1997 followed by the DP224 in 1999. Giving users
even quicker access to all the parameters from the front panel
of the units the DP226 soon became the benchmark for speaker management
systems. Along with the hardware control, XTA also increased the
capabilities of its software platform, AudioCore, allowing users
to remotely and even wirelessly adjust the entire system using
multiple controllers. The DP226 and DP224 were soon further complimented
by the DP6i - an installation version of the DP226, offering the
same fantastic sound quality and power, but with a basic user
interface, designed to be remotely controlled through the ever
popular AudioCore PC software.

With the original success of the
DS400 still being fresh in everyone's mind, the development of
its successor, the DS800, was continuing apace, and the unit also
was released also in 1999.

One of the key features often sited as being a reason as to why
the DP226 sounds so good is the transparency of the limiters,
even when being driven hard into limit. Expanding on this knowledge
of dynamic control, the SIDD and Series Two were launched in 2000/2,
being designed to give engineers the digital dynamic processing
tools needed on analogue desks. With a product range that looked
analogue including dual compressors, dual gates and dynamic EQ
but utilising digital processing the Series Two products have
become very popular especially on the festival scene. With the
advent of digital consoles the Series Two units are still finding
new fans due to their AES input/output option keeping the signal
through the desk digital, but giving the engineer a surface that
looks and feels analogue.

In 2005 XTA launched the 4 Series system controllers and has seen
sales increase by 30%. The DP448 has retained the accessibility
of the DP224/226 but greatly increased the processing power and
facilities available. The completely flexible routing of up to
4 inputs and 8 outputs along with the expanded filter suite the
DP448 is one of the most powerful speaker management systems available.
The DSP platform was completely redesigned, now operating at a
native 96k/24bit rate. Incorporating up to 72db per octave crossover
slopes, a full 28 band graphic EQ on each input, and two stage
D-Max limiting on all the outputs with total remote control from
AudioCore the DP448 has again set the standard for system management.

AudioCore was first available as a relatively basic Windows 3.1
package to control DP100 units. As new products were developed,
the capabilities of the platform have been expanded upon, with
a major “step-up” in performance being the addition
of “Array Control”, initially designed for use with
the Rolling Stones world tour in 1999.
This tour included a huge arsenal of DP226s to control the entire
db Sound EV X-Array system and was a tremendous success, helping
the DP226 to become the industry standard that it still is, eight
years later.

To this day
AudioCore sits at the heart of the system, giving engineers and
technical staff the tools they need to get the job done fast.
AudioCore has evolved over the last ten years from our R&D
staff listening to the users and spending as much time at as many
gigs and festivals as possible evolving a platform that is intuitive,
stable and simple to use.

With the success of the DP226 and DP224 around the world XTA needed
to expand not only its production space but also offer its R&D
staff the environment they needed to be able to create innovative
digital products. Just as importantly dedicated demo rooms were
created to allow for extensive listening tests. In 2001 XTA moved
into purpose built premises, and in 2005 expanded this space and
building to accommodate its continued growth.
 From
Old Shed to New Factory!
Constantly looking at the future, XTA started a research program
in 2003 on class D amplifier technology. The first two products
to emerge from this work have been the BP401 and BP501 - hugely
powerful dual mono digital amplifiers with comprehensive DSP and
microprocessor protection, diagnostics and monitoring in a remarkably
small package. The first client for these OEM units was Funktion
One, who were so impressed with the sound quality and power of
these modules that they redesigned all their subs and the infamous
Res2 to produce active versions.

In March 2007, after over two years of talks, the directors of
both companies came to the decision to merge XTA and MC2. This
was completed just in time for Pro Light and Sound held in Frankfurt
and was announced at the show. The deal saw Andrew Grayland leaving
the group as a director and shareholder but continuing to work
on a consultancy basis for the companies. Along with XTA and MC2
one more company completes the new cluster of business, Quested
Monitoring, having been acquired by MC2 in 2004. Combining the
recourses of all three companies, XTA is set to bring some very
new and exciting products to the market. With a view to also start
an education program at its UK headquarters XTA is continuing
its growth and reputation for exceptional products and service.
