Introduction
The
DSP-2040
are powerful DSP based audio processors, 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
units have up to two inputs and four outputs which can be configured in a selection of basic crossover
modes – 2 x 2 way; 1 x 3 way + 1 Aux; and 1 x 4 way (as applicable to i/o configurations). They also offer a
“free assign” mode, which allows completely flexible routing of any output from any combination of 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
behaviours.
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.
A GPI interface may also be fitted to allow remote memory recalls using simple switch closure apparatus.
Security lock-out is available for all controls.
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.
TM
A completely new SHARC
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 256 memories, with security lockout.
