SAFETY & INSTALLATION INFORMATION

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

SAFETY & INSTALLATION INFORMATION

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.

MIXER & SOURCE SELECTORS

1 RB-SS10 10 Way Stereo Analogue Source Selector/Mixer

Introduction

Fig 1-1: RB-SS10 Front Panel.

The RB-SS10 10 Way Stereo Analogue Source Selector/Mixer is a 1U rack-mount unit that produces a stereo analogue audio output from 10 selectable stereo analogue sources. There are 10 illuminated front panel push buttons, which select and indicate the current channel selection. The selection and indication is also available through a remote connector on the rear panel. To stop accidental front panel selection there is a remote input to inhibit the front panel buttons.

As well as being able to act as a source select module, the RB-SS10 can act as a mixer, by enabling the mix mode (using the remote input).

The gain for left and right inputs can be individually adjusted by using the preset potentiometers on the front panel.

As well as routing the selected audio signal, the unit will also route a remote signal input through the remote connector to the selected input source, for starting external audio equipment such as a CD player.

The front panel headphone output has its own volume control, which is independent of the level adjustment for the main outputs, and has a maximum output level of +12dBu. The volume control can be made to also alter the output level of the main XLR outputs by using a switch on the rear panel to enable/disable this feature.

There is a designation strip on the front panel, useful for giving the buttons a meaningful description. The strip covers the input gain controls so that once congured, they can’t easily be altered – ideal for installation work.

The LED on the front panel is used to indicate that power is present on the unit.

Illuminated Push Buttons

The front panel contains 10 illuminated push buttons, used for selecting an analogue source. The push button illuminates when the input is selected. The status of pin 12 on the remote connector determines whether the unit is in the selector mode, or the mix mode. When pin 12 is connected to 0V, mix mode is enabled.

In selector mode, one push of a button will select the desired analogue stereo source and pushing the button again will turn it o.

Volume Control

Page 17

MIXER & SOURCE SELECTORS

In mix mode, each button you press will select that source allowing multiple sources to be mixed to a single output. Pressing the button again will switch o a source.

There is also a remote input to inhibit the front panel switches. When the front panel inhibit is active, pressing the front panel switches has no eect on the current channel selection.

Front Panel Gain Controls

The input gain can be individually adjusted for left and right channels through pre-set potentiometers which are accessible through the front panel. The gain range of the input is

-8dBu to +20dBu.

Headphone Output

The front panel headphone output is a ¼” stereo jack socket and is designed to drive 150mW into 32 - 600 professional headphones.

Volume Control

The volume control is used to alter the headphone output. It can also be used to alter the main XLR output levels by using a rear panel switch to enable/disable the control.

Additional Modes

An option to set the unit in dierent modes of operation is available and can be congured at anytime while the unit is powered.

There are currently three modes of operation: Alternate mode, Latched mode and Protected Alternate mode: -

Alternate Mode In this mode the channels are selected and deselected by a press of the button, as described previously.

Latched Mode In this mode the selected channel is active only while the button is pressed. As soon as button is released the channel becomes inactive.

Protected Alternate Mode

Operates in a similar manner to the Alternate mode, but a channel cannot be turned o unless switching to another input or while operating in mix-mode and there is more than one channel active. In other words, there will always be a channel routed to the output. NOTE: after setting this mode there will be no channel selected.

Conguring the Additional Modes

While the unit is powered, hold down the input 10 button and press the input 5 button ve times. Once completed, the input 10 button will start to ash and the rst 3 input buttons will display the current operating mode (as shown below). To change the mode, simply press the input 10 and the buttons will indicate the newly selected mode. Once the required operating mode has been set the unit will restart within ve seconds from the last button press.

2 RB-DSS10 10 Way Stereo Digital Source Selector

Introduction

Fig 2-1: RB-DSS10 Front Panel.

The RB-DSS10 10 Way stereo Digital Source Selector is a 1U rack-mount which produces an AES/EBU and S/PDIF level digital audio output from 10 selectable AES/EBU or S/PDIF digital input signals. There are 10 illuminated front panel push buttons, which select and indicate the current channel selection. The selection and indication is also available through a remote connector on the rear panel. To stop accidental front panel selection there is a remote input to inhibit the front panel buttons.

The digital receivers in this unit are fully 24 bit, 96kHz capable. When an input is selected from the front panel, or remotely, the unit will attempt to capture the incoming signal on either the AES/EBU or the S/PDIF signal inputs, with priority given to the AES/EBU input. If the AES/EBU signal becomes locked while the S/PDIF signal is routed, the unit will automatically switch to the incoming AES/EBU signal.

Once the receiver has successfully locked to a digital input, the LED illuminates, the tally is made, and the audio is routed simultaneously to both the digital audio outputs and converted to analogue audio for monitoring on the front panel headphone socket. If the incoming audio signal is not present, the push button LED and remote tally ash to indicate that the incoming digital signal is missing.

The headphone output has its own volume control, which is independent of the level adjustment for the main outputs, and has a maximum output level of +12dBu.

There is a designation strip on the front panel, useful for giving the buttons a meaningful description.

The LED on the front panel is used to indicate that power is present on the unit. However, it also has a secondary role to indicate whether the selected channel is routing the AES/EBU (red LED) or S/PDIF input (amber LED).

Additional Modes

An option to set the unit in dierent modes of operation is available and can be congured at anytime while the unit is powered.

There are currently three modes of operation: Alternate mode, Latched mode and Protected Alternate mode: -

Alternate Mode In this mode the channels are selected and deselected by a press of the button, as described previously.

Latched Mode In this mode the selected channel is active only while the button is pressed. As soon as button is released the channel becomes inactive.

Protected Alternate Mode

Operates in a similar manner to the Alternate mode, but a channel cannot be turned o unless switching to another input. In other words, there will always be a channel routed to the output. NOTE: after setting this mode there will be no channel selected.
