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.

Progress
Following on from the Sonifex Sovereign range of audio mixers, the S1 combines all the
features needed of a radio broadcast mixer in a stylish, ush-mounting chassis: a wide range
of input and output channels, CUE/PFL, fader-start operation of equipment, automatic
monitor muting on mic-live, light switching remote outputs, EQ on input modules, two
auxiliary busses,two external inputs and a main program audio bus.
Flexible
The S1 is a highly congurable unit and has been designed to be jumper free, allowing the
user to alter the conguration quickly whilst still on air rather than having to take apart the
unit armed with a pair of tweezers and a magnifying glass. The majority of the desk can be
setup and controlled using the Sonifex SCI Software. This opens up a world of options:

Installation Notes
Atmosphere
The S1 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 S1 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. In all cases the S1 mixer should be
installed and serviced by qualied personnel.
Dimensions and Cut-Out Sizes
The cut-out size is for reference only and should be checked with your mixer.
