FONESTAR FS-2481E Instruction Manual

We recommend you read the instruction manual before switching on the machine and follow the instructions that are given. Keep the manual for future reference. SECURITY AND THE ENVIRONMENT ELECTRICAL SECURITY Check that the current in the mains connection where the machine is to be installed corresponds to the power supply of the machine. To avoid damaging the equipment, electrical shocks, fire or physical injury when you connect or disconnect the equipment from the power supply, pull the plug firmly out of the mains socket holding the plug, never the cable. Always do this with dry hands. Keep the power supply cable far from sources of heat. Do not put heavy objects on top of it or change it. Clean dust and dirt off the power supply cable regularly. Do not open the machine; you could get an electric shock. CAUTION While installing the machine, make sure it is switched off and unplugged. Do not open the machine. Touching the internal parts is dangerous and you could receive an electric shock. The machine must not be splashed or dripped on. Never place recipients with liquid inside on the machine. Do not place anything inside the machine. LOCATION Place the equipment on a horizontal surface with enough space around it to allow ventilation. Avoid direct sunlight, heat sources and excessive dust. Do not place the machine near magnetic fields or static electricity. Do not use surfaces which vibrate or receive impact. Do not pile machines on top of one another. VENTILATION Never block or cover the ventilation slits on the machine. Do not expose it to direct sunlight or place it near sources of heat. PERIODS OF INACTIVITY When the machine is not going to be used for a long period of time, disconnect it from the mains. If you are using an adapter, take into account that it will continue using electricity even if the machine is switched off. If it is not going to be used for a long period of time, disconnect it from the mains. THE ENVIRONMENT To save energy, switch the machine off when you are not going to use it for a long time. The machine could contain substances that are harmful to the environment or human health. To

when you decide to dispose of it. When you dispose of it remember: it cannot be thrown into a conventional rubbish bin. If it contains or uses batteries, these must be disposed of separately. The machine (without batteries) must be disposed of correctly. Put it in a container specially intended for the collection of electronic and electrical appliances, at the dump or hand it over to the dealer when you purchase similar equipment, so that the dealer can dispose of it correctly (at no added cost). SIGNIFICANCE OF THE SYMBOLS ON THE MACHINE* The symbol formed by the expression “Class 1 laser product” written in a rectangle indicates that visible or invisible laser radiation could be produced. Avoid direct expose to the laser. The symbol formed by a ray of lightening inside a triangle shows that the machine has connection terminals or a circuit with areas with a current which could cause an electric shock, even in normal working conditions. The symbol formed by an exclamation mark in a triangle shows that the instruction manual must be referred to for information on how the machine works and its use. The symbol formed by one square inside another square shows that the machine has double electrical insulation. The European Community symbol shows that the machine complies with the current European Union legislation, as well as its transposition to local legislation. The symbol of a rubbish bin crossed out and over a horizontal line shows that when the product is disposed of it must be done properly, placing it in a special selective electronic and electrical equipment container or through a dealer when purchasing a similar product, at no additional cost. It also shows that the machine was put on the market after 13th August 2005 (European Community Directive 2002/96/CE of Electrical and Electronic recycling, and its Spanish equivalent R.D.208/2005). In accordance with what is set out in the aforementioned decree, FONESTAR is registered in the RAEE (Registro de Aparatos Eléctricos y Electrónicos) in a special section REI (Registro de establecimientos Industriales), with the entry number 001851.

been designed and manufactured restricting the use of certain dangerous materials (Directive 2002/95/CE on the restriction of certain dangerous substances in electrical and electronic appliances, and its transferal to the Spanish regulations, R.D.208/2005). *It is possible that some of these symbols do not appear on the machine. EXEMPTION OF LIABILITY The characteristics of the equipment and the content of the manual can change without forewarning. FONESTAR, S.A. does not assume responsibilities regarding the inappropriate use of the equipment or the information supplied in this instruction manual, and specifically disclaims any implied liability for marketability or fitness for any other use.

Connector: Balanced XLR. 10. 500 mV, 47 kΩ line input. Connector: 6.3 mm balanced stereo jack. 11. Priority terminals to activate the speech only speaker output. 12. 230 V AC input socket. 13. AC fuse holder (10 A). MAINS CONNECTION The power supply source transformer has been designed for 230 V AC. BATTERY CONNECTION (24 V DC) When using a 24 V DC battery as power supply, connect the amplifier to earth using the earth terminal. The system is electrically more stable if the chassis is connected to earth. NOTE: The connection cable to the batteries must have a series rating fuse. The fuse must be F30A quick cut off type. When connecting the battery, make sure to respect polarity. SPEAKER CONNECTION There are two speaker outputs that correspond to the two speaker zones. The main MUSIC/SPEECH output offers output at all times, reproducing the signal present in the amplifier input. It is the general output for 8 Ω and 100 V high impedance line speakers. The secondary SPEECH ONLY output only reproduces the input signal when the priority has been activated using the circuit closure in the PRIORITY terminals. This function is useful when you want a second speaker zone that only occasionally receives announcements. The PRIORITY circuit can be closed by a microphone or a switch. In this case the SPEECH ONLY output can be used as a second zone that is activated or deactivated by a switch.

This output allows the connection of low impedance standard speakers. The lowest load impedance must be 8 Ω. When two or more speakers are connected to this output they must be interconnected so that the load impedance is between 8Ω and 16 Ω. PREAMP/MIXER AND POWER AMP INTERCONNECTION The connection of the preamp/mixer to the FS-2481E power amp can be made with different connectors, depending on user preference: - Using balanced XLR connectors. - Using balanced stereo 6.3 mm jack connectors. - Using unbalanced RCA connectors. POWER AMPLIFIER CONFIGURATION - Internal selection of INPUT SENSITIVITY: The amplifier has three selectable input sensitivities (1 V, 500 mV, 100 mV). Disconnect the amplifier from the mains, remove the lid and select the input sensitivity in the SW401 selector on the PAB-1 printed circuit board. The input sensitivity is 500 mV by default. - Working mode selection: When several power amps are interconnected there is a possibility to select the working mode in each one of them. Working modes: - One unit: For systems working as just one unit, select the STAND ALONE position in the SW403 and SW404 selectors. This is the usual way of working and is the default configuration. Several amps can be used in cascade, each one maintaining its own volume. - More than one unit: With two or three units working in cascade, one must be assigned the role of MASTER. This is done by selecting this position in the SW403 and SW404 selectors. The others must be assigned the secondary role of SLAVE. In this working mode the MASTER VR volume control is cancelled in the secondary units and the volume is controlled by the MASTER unit. The working modesare selected using 2 selectors (SW403 and SW404) found on the PAB-1 printed circuit board. SW403 SW404 WORKING MODES STAND ALONE (default configuration, only one system) MASTER (Main unit) SLAVE (Secondary unit) The working mode is STAND ALONE by default. IMPORTANT: For the amps to work as MASTER and SLAVE, the input and output signal connection must be made exclusively using the UNBALANCED RCA connectors.
