Installation Information
Atmosphere
The units should be installed in an area that is not subject to excessive temperature variation
(<0°C, >50°C), moisture, dust or vibration.
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 identified 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 affected 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 offered as RoHS compliant, or LF, only after sufficient 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 identification of RoHS
compliance. Thus whilst every effort is made to ensure compliance, Sonifex Ltd makes no
warranty, or certification, or declaration of compliance concerning said components.
Sonifex Ltd defines “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.

INTRODUCTION
1 Passive Digital Splitters Introduction
The Passive Digital AES Splitters are a range of small form units, for splitting digital AES3/
AES3ID audio from a single source to up to 3 destinations.
There are two Passive Digital Splitter products:
CM-AESX3 3 Way Passive Digital AES3 Splitter, with XLR connections.
CM-AESB3 3 Way Passive Digital AES3ID Splitter, with BNC connections.
2 CM-AESX3 3 Way Passive Digital AES3 Splitter, with XLR
The CM-AESX3 is a passive digital splitter, designed to split a single AES3 source to up to
three destinations, using Neutrik XLR connectors. 110Ω termination can be applied, if
desired to unconnected outputs. The CM-AESX3 is a single “one-to-three” splitter housed in
a small form box, and utilises a locking XLR socket for the input connector.

AES/EBU input(s)
The single digital audio input is via a female XLR connector with the following pin
assignment:
Pin 1: 0V Common
Pin 2: Phase
Pin 3: Non Phase
AES/EBU outputs 1-3
The digital audio outputs are via male XLR connectors with the following pin assignment:
Pin 1: 0V Common
Pin 2: Phase
Pin 3: Non Phase
Termination switches
It is possible to terminate Output 2 and Output 3 with 110Ω in the event that they are not
connected to a destination device. It may be necessary to remove termination from an
unused output if a used output is connected to a destination via a long cable run, in order to
increase the level of the AES3 carrier signal.
