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
Fig 1-1: CM-CU1 Commentator Unit
The CM-CU1 Commentator Unit is a high quality, portable broadcast mixer and 4-wire talkback unit. Its sturdy construction and flexibility of features make it suitable for use in a wide variety of environments.
It provides a fully featured commentator position with both limited, transformer balanced, and non-limited, electronically balanced outputs. A limit indicator on the main panel shows when the adjustable limiter on the mix output is active, and a bright 21 segment LED PPM meter, which can be disabled, shows the main output level.
The line input can be configured to remain present at the mix output even if the commentator is off air, making it useful for routing crowd effects or pre-recorded material to the programme feed. Its presence in the commentator’s headphones is also configurable to suit the application.
Four talkback output channels, with a built in limiter, are available to the commentator. They have adjustable gain and can be linked to provide simultaneous operation.
A wide input gain range and switchable phantom power provides support for a variety of microphone types, from high output phantom units to low output ribbon microphones.
There are 5 transformer balanced return audio inputs which, along with the commentator input, are routed to the headphone monitor controls. With these headphone controls, any input can be level adjusted, and sent to either the left, right or both ears.

2 Main Panel Controls & Indicators
Fig 2-1: Top Panel View Of CM-CU1
The main panel of the Commentator Unit is split into two areas. At the top are the mix output PPM meter display, mix output limiter active indicator and the power indicator LED. Below this are the main commentator position controls, with the TALKBACK and ON AIR buttons located towards the bottom.
ON AIR Button
The ON AIR button routes the commentator microphone input signal to the Comm Output and to the Mix Output. This button has a latching action; press to activate and press again to deactivate. When the On Air control is active, the button illuminates red and the corresponding open collector driver output on the GPIO port is activated.
The line input signal is permanently routed to the mix output by default. It is possible to configure the line input signal to be routed only when the ON AIR button is active. See Page 10 ‘Config Page 2 - Line Input Routing to Output’ for details.
TALKBACK Buttons
The TALKBACK A, B, C and D buttons allow the commentator’s microphone signal to be redirected to the corresponding Talkback Output. The commentator output is muted and the commentator’s signal is removed from the Mix Output. The five return audio inputs

Prog, A, B, C and D function normally when a Talkback channel is active, allowing full­duplex communication between the commentator and a third party. These buttons have a momentary action by default; press to activate, release to deactivate. See Page 9 ‘Config Page 1 - ON AIR Button Enable/Disable & TALKBACK Button Latching Modes’ for details of how to change the button action. When a Talkback control is active, the button illuminates green and the corresponding open collector driver output on the GPIO port is activated.
Headphone Monitor Controls
The commentator position has a set of six headphone controls which allows it to monitor all of the units’ return audio and the commentator and line inputs, if active. Each available input has an associated level adjustment potentiometer and a headphone channel selector switch. Each potentiometer provides a level adjustment from “full off” to “full on”, and the headphone channel selector determines which ear the associated signal is routed to; either the left, the right or to both ears when the switch is in the centre position. By default, the commentator input signal is only routed to the headphone monitor controls when the On Air control is active. It is possible to route this signal to the headphones permanently, regardless of the state of the On Air control line input. See Page 10 ‘Config Page 3 ­Commentator Mic & Line Input Routing to Headphones’ for details.
It is also possible to configure the presence of the line input signal in the headphones using Config Page 3 too. By default, the line input signal is permanently routed to the headphone monitor controls.
PPM Meter Display
The 21 segment LED PPM meter display indicates the level of the signal on the Mix Output. The PPM scale conforms to IEC60268-10 11a and a dB scale is also shown. There are options to set the brightness level of the PPM meter, or it can be disabled if it is not required. See Page 11 ‘Config Page 5 - Limit LED Colour & Limit/Power LED Brightness’ for details.
Limit LED
The limit LED illuminates when the adjustable limiter on the Mix Output is enabled and active. See Page 6 for information on the Limiter controls. The colour and brightness level of the limit LED can be changed if required. See Page 11 ‘Config Page 5 - Limit LED Colour & Limit/Power LED Brightness’ for details.
Power LED
The power LED illuminates red to indicate that the unit has power from either of its mains or DC inputs. If this indicator is not on when mains power is connected to the unit, this may indicate a ruptured mains fuse or a problem with the internal power supply module. The power LED also indicates when the unit is in setup mode by flashing amber/red.

4 Rear Panel Controls & Connections
Fig 3-2: Rear Panel View Of CM-CU1
The rear panel of the Commentator Unit carries the five return audio inputs and commentator, talkback and mix output connectors. Four additional controls are located on the rear panel; On Air Lock, Talkback Gang, Limiter and Test Tone.
On Air Lock Controls
The On Air Lock prevents the commentator’s ON AIR button from being deactivated accidentally. When the On Air Lock is enabled, the on air channel can only be deactivated by first pressing the pushbutton located next to the On Air Lock switch. A slot in the rear panel makes locating the On Air Lock pushbutton easy; simply position your finger in the slot in the rear panel, indicated by the “ON AIR LOCK” text on the top panel, then slide your finger down the slot until you reach the pushbutton.
Talkback Controls
The TALKBACK GANG switch links the operation of each of the commentator’s TALKBACK A, B, C and D buttons. When this switch is on, pressing one of the TALKBACK buttons automatically activates the other TALKBACK buttons. Up to an additional 12dB of gain is available on all talkback outputs, if required. This is applied prior to the limiter and is adjusted using the rear panel GAIN potentiometer.
Limiter Controls
The LIMITER ON/OFF switch and LEVEL potentiometer control the limiter that is applied to the Mix Output. The potentiometer sets the threshold level at which the limiter becomes active, and has a range of between -13dB to the maximum output level of +25dB.
Test Tone Switch
The CM-CU1 has a built in test tone generator which selectively routes a line-up tone to all outputs to assist channel identification and cabling checks. There are two test tone modes; manual and auto. Regardless of mode, a 1kHz tone is permanently routed to the Mix Output and the PPM meter will indicate that the signal level is 0dBu. The test tone is enabled by sliding the TEST TONE switch to the upper “ON” position. To change the test tone mode; keep the Talkback B and Talkback C buttons pressed for 2.5 seconds.

Test Tone Manual Mode
With the test tone in manual mode, the ON AIR and TALKBACK buttons flash amber. The test tone can be routed to the Comm and Talkback Outputs by pressing the ON AIR or corresponding TALKBACK buttons. The ON AIR button illuminates red when pressed and the TALKBACK buttons illuminate green. When the button is released, the tone on that output is muted.
Test Tone Auto Mode
With the test tone in auto mode, each of the Comm and Talkback outputs are automatically identified by a unique number of short tone bursts, lasting 0.25 seconds each, which are repeated every 3 seconds. Each button flashes when tone is being routed to the corresponding output. The number of pulses on each output is shown below:
Comm 1 pulse Talkback A 2 pulses Talkback B 3 pulses Talkback C 4 pulses Talkback D 5 pulses
The 5 return audio inputs function normally when the test tone is enabled. This could be useful in allowing the user to receive instructions on which channel to output tone to when using the test tone in manual mode. When the test tone is disabled, normal operating mode is resumed and the On Air and Talkback buttons return to the state they were in prior to entering test tone mode.
Return Audio Inputs
The five transformer balanced return audio inputs, Prog, A, B, C and D are via 3 pin female XLR-3 connectors with the following connections:
Pin 1: Ground Pin 2: Phase Pin 3: Non-phase
Audio Outputs
The electronically balanced commentator output, and the transformer balanced talkback A, B, C and D and mix outputs are all via 3 pin male XLR-3 connectors with the following connections:
Pin 1: Ground Pin 2: Phase Pin 3: Non-phase
DC Supply Input
The commentator unit can be powered from an external, regulated 12V or 24V DC power source. The DC input is via a 4 pin male XLR-4 connector with the following connections:

Config Page 7 - Save/Load Configurations & Firmware Version
The last page allows you to save the current option settings to either of two available backup sets that are unaffected by subsequent changes to the option settings. The backup sets can then be reloaded when required. The load/save functions only work whilst in Config Page 7.
Version Firmware
config Page 7 shows the current firmware version by flashing the Limit LED in a recurring sequence i.e. 1 flash for version 1, 2 flashes for version 2, etc.
To Save The Current Option Settings to Backup Set 1
Press and hold the ON AIR and TALKBACK B buttons for 2 seconds. These buttons will then illuminate red to verify that the options have been saved to backup set 1.
To Save The Current Option Settings to Backup Set 2
Press and hold the ON AIR and TALKBACK D buttons for 2 seconds. These buttons will then illuminate red to verify that the options have been saved to backup set 2.
To Load Backup Set 1 & Overwrite The Current Option Settings
Press and hold the ON AIR and TALKBACK A buttons for 2 seconds. These buttons will then illuminate red to verify that backup set 1 has been loaded.
To Load Backup Set 2 & Overwrite The Current Option Settings
Press and hold the ON AIR and TALKBACK C buttons for 2 seconds. These buttons will then illuminate red to verify that backup set 2 has been loaded.
To Exit Setup Mode
Press and hold the TALKBACK A and TALKBACK B buttons for 3 seconds. When the power indicator stops flashing, the On Air buttons can be released and the unit enters normal operating mode.
In addition to being able to load and save options, it is also possible to return the setup options to their factory default settings. Please note: all changes made to the options settings will be lost. Loading of the factory defaults does not affect the options stored in the backup sets.
To Return The Current Option Settings to Factory Defaults
Apply power to the unit whilst keeping TALKBACK C and TALKBACK D buttons pressed for 5 seconds. These buttons then illuminate red to verify that the default options have been loaded. After the default options have been restored, the unit returns to normal operating mode.
