4) Introduction
The DX1.5 is a powerful DSP based audio processor, ideally suited for install applications,
where they combine the functions of a multitude of conventional products in a compact 1U
unit. To achieve this, the unit’s have inputs and outputs which can be configured in a
selection of basic crossover modes. The DX1.5 also offers a “free assign” mode, which
allows completely flexible routing of any output from any combination of the inputs.
Each input has a gain control, variable delay and a further eight bands of fully parametric
equalisation. The parametric filter bands have a large selection of different filter types
available, including shelving.
Each output has a gain control, variable delay, high and low pass crossover filters, nine bands
of fully parametric equalisation, polarity switching and, additionally, a fully featured limiter, and
a final clip limiter. The crossover filters offer slopes of up to 48dB/Octave., with a variety of
responses available.
Security lock-out is available for all controls.
The DX1.5 is also equipped with AES/EBU digital inputs, and includes a sample rate
converter, capable of accepting anything from 32kHz up to 192kHz.
5) Features
Superb audio quality – carefully optimised double precision signal processing coupled with 24
bit conversion ensure a dynamic range in excess of 117dB. The high sampling rate of 96kHz
means minimal filtering providing exceptional sonic purity with a bandwidth in excess of
32kHz.
A flexible input/output multi-mode format caters for any configuration, regardless of scale.
Both routing of inputs to outputs, and ganging (for editing) are completely flexible.
A completely new SHARC
TM
-based DSP platform supplies phenomenal computational power,
allowing the unit to provide not only multiple bands of standard parametric equalisation on
every input and output, but an additional full spectrum graphic equaliser on each of the four
inputs. This additional power also permits both program limiters and no overshoot clip limiters
on each output.
Delay of up to 650mS may be independently set for each output, with an exceptionally fine
minimum increment of 300nS, which corresponds to a distance change of 0.1mm!
The comprehensive standard specification also includes up to 255 memories.
