Safety of Mains Operated Equipment
This equipment has been designed to meet the safety regulations currently advised
in the country of purchase and it conforms to the safety regulations specied by
use of the CE Mark.
The power supply is rated to 95 - 265VAC at 47 – 63Hz with a fuse of 2A.
Warning: There are no user serviceably parts inside the machine. If you should ever
need to look inside the unit, always disconnect the mains supply before removing the
equipment covers.
Fuse Rating
The product is supplied with a single fuse in the live conducting path of the power-in feed
at the power supply. For reasons of safety it is important that the correct rating and type of
fuse is used. Incorrectly rated fuses could present a possible re hazard, under equipment
fault conditions.
Power Cable and Connection
An IEC power connector is supplied with the product, which has a moulded plug attached –
this is a legal requirement. If no moulded plug has been supplied with your product, please
contact your supplier, because an IEC connector is always supplied from the
Sonifex factory.
If for any reason, you need to use the product with a dierent power cable, you should use

WEEE & RoHS Directives - Sonifex Statement
The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on
13 February 2003, along with the related Directive 2002/95/EC on Restrictions
of the use of certain Hazardous Substances in electrical and electronic
equipment (RoHS).
The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the
impacts of electrical and electronic equipment on the environment during their life times
and when they become waste. It applies to a huge spectrum of products. It encourages
and sets criteria for the collection, treatment, recycling and recovery of waste electrical and
electronic equipment. All products manufactured by Sonifex Ltd have the WEEE directive
label placed on the case. It gives a contact for individuals who are unsure about the correct
procedure when the product has reached its “end of use”.
Sonifex Ltd will be happy to give you information about local organisations that can
reprocess the products, or alternatively all products that have reached “end of use”can be
returned to Sonifex and will be reprocessed correctly free of charge.
Sonifex Ltd has phased out the use of certain hazardous substances identied in the
European Union’s Restriction of Hazardous Substances (RoHS) directive. The RoHS directive
limits the use of certain hazardous substances currently used in EEE manufacture, including
lead, mercury, cadmium, hexavalent chromium, and halide-containing compounds PBB
(polybrominated biphenyl) and PBDE (polybrominated diphenyl ether). Elimination of these
substances will result in more environmentally friendly recycling of electronic equipment.
For the products which Sonifex manufacture, the main area where products were aected
was in the use of lead for manufacturing and assembling electronics circuit boards.
Sonifex Ltd practices lead-free (LF) manufacturing processes. LF solder is used on the
surface-mount PCB manufacturing processes and for hand soldering. The printed circuit
boards (PCBs) used are either gold plated, or immersion tin plated, both of which use no
lead. Historically the PCBs were hot air solder levelled (HASL) PCBs which used tin/lead
based solder.
The manufacturing processes include the assembly of purchased components from various
sources. Product is oered as RoHS compliant, or LF, only after sucient evidence is received
from the component manufacturers that their components are RoHS compliant. Sonifex
Ltd relies solely on the distributor, or manufacturer, of the components for identication of
RoHS compliance. Thus whilst every eort is made to ensure compliance, Sonifex Ltd makes
no warranty, or certication, or declaration of compliance concerning said components.
Sonifex Ltd denes“Lead Free”as pertaining to any product, which has been manufactured
by Sonifex Ltd using components which have been declared by the manufacturers as
“Lead Free”. All statements by Sonifex Ltd of RoHS compliance are based on component
manufacturer documentation.

1 Introduction
S2 is a new breed of radio broadcast mixer. Using the latest technology components,
S2 oers digital audio quality with analogue reliability in a modular format. S2 has both
digital and analogue input channels, together with simultaneous analogue and digital
outputs.
Following on from the Sovereign range of audio mixers, S2 combines all the features needed
of a radio broadcast mixer in a stylish, ush-mounting chassis: a wide range of input and
output channels, PFL/Cue, fader-start operation of equipment, automatic monitor muting
on mic-live, light switching remote outputs, optional EQ on input modules, gram amp input
options and 2 main audio buses, allowing you to broadcast on the PGM bus while recording
on the AUD bus, with bus output selection on each module.

2 Installation Notes
Atmosphere
The S2 mixer should be installed in an area which is not subject to excessive heat or cold.
Also, you should avoid installing it in atmospheric conditions which are dusty, smoky, or
dirty, or where there is moisture or vibration.
Do not use any liquids to clean the fascia of the mixer: a soft dry brush is ideal. Use a clean
cloth moistened with water or ethyl alcohol to clean the trim and scribble pads. Other
solvents may cause damage to paint or plastic parts.
Electromagnetic Radiation
Avoid using the S2 mixer close to strong sources of electromagnetic radiation such as, video
monitors or high power electric cabling. This may cause degradation of the audio quality
due to induced voltages in connecting leads and chassis. The S2 power supply should also
be sited at least 1 metre from the mixer.
In all cases the S2 mixer and power supply should be installed and serviced by qualied
personnel.
Dimensions and Cut-Out Sizes
The S2 mixer consists of a stainless steel chassis with plastic side and top mouldings and
aluminium front trim. The dimensions for the mixer below include the mouldings and trim.
The cut-out size is for reference only and should be checked with your mixer.

Channel Conguration
Each of the channels can be re-congured by jumpers, which are displayed in the “Channel
Options and Jumper Settings”section of each chapter. You should ensure that you are
thoroughly familiar with the settings available for each channel before attempting
installation of the mixer. This is because some options may involve moving jumpers on
several channels to change the conguration of the mixer.
Connectors and Cabling
Many of the problems associated with installing and maintaining a mixing console are due
to the use of poor cables or faulty connections. It is recommended that, wherever possible,
pre-wired cables are purchased from recommended manufacturers. If you need bespoke
cables making, please ensure that a qualied engineer carries out the work.
