DSP-4080
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.
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.
TM
TM
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.

Operating the device
Note about operation with AudioCore software:
The following operating information covers setup and control of the DSP-4080 via the front panel controls
only. Please consult the manual supplied with this software for information regarding full computer control.
Start-up procedure
Switching on the unit will display a brief message detailing the unit type and software version running
and all LEDs will briefly illuminate. The unit will then begin its countdown to the wake-up procedure, during
which time the audio will fade up to the level last set. Metering will begin to operate when the fade-up starts.
Preliminary Set-up
The procedure below should be followed when first installing a DSP-4080.
Design your crossover! To do this, press MENU, and use the BACK or NEXT key to select 'Crossover
sub-menu' and then press ENTER. Use the BACK or NEXT key to select 'Design a crossover' and then
press ENTER. Finally, use the BACK or NEXT key to select the desired routing and follow the set-up wizard
to finalise your design.
Note that when in a menu, ENTER is always used to confirm selections. The current selection is marked
with an asterisk '*'.
Use the EDIT keys on each output channel with the BACK and NEXT keys to select the high pass filters,
low pass filters, parametrics etc. Note that when designing a new crossover, the high and low pass filters will
be set to default values.
Use the EDIT keys on each input channel with the BACK and NEXT keys to select the gain, delay and
parametrics available on each input.
Information:
Note that if no action is taken in menu mode, the unit will return to normal 'default' mode after about
twenty (20) seconds. Repeat the above directions to return to menu mode.

Routing Options and Processing Blocks
Due to the completely new DSP platform, the routing possibilities within the DSP-4080 has been made
completely flexible, with a matrix available allowing any combination of inputs to be routed to any output. The
additional DSP power has permitted the inclusion of more processing blocks, even considering the extra
inputs and outputs, and the doubling of sample rate.
To reduce set-up time and aid usability, several standard configurations are available as described in a
later section.
This section will outline the processing blocks available in relation to the signal path, and explain the
various options for routing, including the “Free Assign” mode, which opens up completely flexible channel
routing.
Input Channel Makeup
The diagram below shows the processing available on each of the four input channels, before routing to the
matrix.
Output Channel Makeup
The diagram below shows the processing available on each of the eight output channels, after routing
from the matrix.
Preset Routing Configurations
In addition to the ability to assign any combination of inputs to any output, a number of preset
configurations are provided, for use when designing a crossover from scratch. These have the advantage of
suggested settings for the high and low pass filters to useful basic starting points, to filter the different
outputs as appropriate for the chosen configuration. These may, of course, be freely modified afterwards
should they not suit the requirements exactly.
The diagrams on the following pages show the connections made between inputs and outputs, and the
suggested values chosen for the high and low pass filters.
