Introduction
The
DSP-4080
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 with extensive remote
control capabilities. To achieve this, the units have up to four inputs and eight outputs which can be
configured in a selection of basic crossover modes – 4 x 2 way; 2 x 3 way + 2 Aux; 2 x 4 way; and 1 x 8 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, notch,
band-pass, phase and elliptical 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.
Remote control is catered for in the form of RS232 and RS485 ports, and multiple user memories are
provided for the storage and recall of settings. A GPI interface may also be fitted to allow remote memory
recalls using simple switch closure apparatus.
Note that only the RS232 and RS485 interfaces offer full remote control of this product – the GPI
interface may only be used for memory recall (program change) purposes.
Security lock-out is available for all controls.
The
DSP-4080
are also equipped with AES/EBU digital inputs and outputs, and include a sample rate
converter, capable of accepting anything from 32kHz up tp 192kHz.

They may be controlled externally by XTA's proprietary Windows
software, along with existing
and future 'AudioCore' products.
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, and remote control via
RS232 or RS485 ports, with security lockout.
