Introduction
The DP226 is a powerful DSP based audio processor, ideally suited for live sound
applications, where it combines the functions of a multitude of conventional products
in a compact 1U unit. To achieve this, the DP226 has two inputs and six outputs
which can be configured in five basic crossover modes – 3 x 2 way; 2 x 3 way; 4 way;
5 way; and 6 way.
Each input has a gain control, variable delay and eight bands of fully parametric
equalisation. Each output has a gain control, variable delay, high and low pass filters,
five bands of fully parametric equalisation, polarity switching and, additionally, a fully
featured limiter.
Remote control is catered for in the form of MIDI, RS232 and RS485 ports, and
multiple user memories are provided for the storage and recall of settings.. Multi-
part security lock-out is available for all controls.
The DP226 is also available with optional AES/EBU digital inputs and outputs.
It has been designed for quick, intuitive adjustment through the use of multiple
controls to provide an easy-to-use interface. Alternatively, it may be controlled
externally by XTA’s proprietary Windows
TM
software, along with
existing and future ‘Audiocore’ products.
Features
♦
Superb audio quality – carefully optimised double precision signal processing
coupled with a 40-bit internal data path ensures a dynamic range in excess of
110dB. The high sampling rate means minimal filtering providing exceptional
sonic purity.
♦
A flexible 2-input/6-output multi-mode format caters for any crossover
configuration, regardless of scale.
♦
A total of 46 parametric equalisation bands are available, each pro15
to –30dB of gain at centre frequencies between 20Hz and 20kHz, with a wide
range of ‘Q’s available between 0.4 to 128. All parameters feature fine
resolution with 1/36 octave frequency steps, 0.1dB gain increments, and 100
‘Q’ settings. Any parametric section can also be set to operate as a high or
low shelving filter.
♦
Each output features a high performance limiter, provided with complete
control over attack, release and threshold parameters. To aid set-up, the
output meters show headroom to the limiter threshold, and use time
constants that track those of the limiter to display precise power usage.
