4 Series 4 Series

Introduction

The 4 Series 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, a 28 band graphic equaliser 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
storage and recall of settings. 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.

The 4 Series 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
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
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, and remote control via RS232 or RS485
ports, with security lockout.

XTA’s new proprietary Complex Unified Nyquist Truncation algorithm ensures that no matter how much equalisation is
applied to a channel, there will always be sufficient headroom available to cater for it.

EDIT buttons illuminate yellow when pressed, and access gain on first press, then last
viewed parameter on second press, then exit on third press.
Input meters show dB from clipping point of the analogue to digital converters.
Yellow (0dB) LED illuminates 3dB from clipping. Red CLIP LED may illuminate
independently from the rest of the meter to show digital overflow. All four CLIP

the audio will fade up to the level last set. Metering will begin to operate when the fade-up starts.

Preliminary Set-up

and then press ENTER. Finally, use the BACK or NEXT key to select the desired routing
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.

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 4 Series have 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 (

DP448 shown)

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.

the routing for any output, press its EDIT key, and then choose the required input channel combination by just pressing
the input EDIT keys as appropriate. The input combinations can also be stepped through in turn by pressing NEXT, or
