We take this opportunity to thank you for buying this product.
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 T E 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.
T E 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 minimize the effect of these
substances the machine must be correctly managed and recycled 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 exposure
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.
The symbol Ro S (Restriction of azardous Substances) shows that the product has been
designed and manufactured restricting the use of certain dangerous materials (Directive
2002/95/EC 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.

DESCRIPTION
The TFA-500 is a 100 V line transformer for amplifiers. It converts an amplifier or 4-8 Ω low impedance stereo
power amp output into a high impedance output for speakers 100 or 70 V line transformer.
Low impedance and 100 V line speakers can be connected at the same time.
It is perfect for P.A. applications and background music when a large number of speakers need to be
connected to just one amplifier.

CONTROLS AND FUNCTIONS
FRONT PANEL
1.- INPUT 1: LED indicator that lights up when a signal is detected in INPUT 1.
2.- INPUT 2: LED indicator that lights up when a signal is detected in INPUT 2.
BACK PANEL
1.- OUTPUT 2: 100 and 70 V line high impedance speaker output terminals for channel 2. Only use one of
the output lines.
2.- OUTPUT 1: 100 and 70 V line high impedance speaker output terminals for channel 1. Only use one of
the output lines.
3.- STEREO/BRIDGE MONO: selector for choosing the operating mode. You can choose between stereo
mode (2 stereo input channels or 2 individual input channels, in INPUT 1 and INPUT 2) and mono bridge
mode (just 1 input channel, in INPUT 1).
4.- INPUT 2: INPUT 2 signal input connector. For connecting the output signal of one channel from the low
impedance amplifier.
5.- INPUT 1 BRIDGE MONO: INPUT 1 signal connector. For connecting the output signal of one channel
from the low impedance amplifier. Use this input if you are going to select bridge mode.

CONNECTION
Note: to avoid damage, the power of the input signals connected to INPUT 1 and INPUT 2 must not
exceed the power supported: 500 W RMS per channel in stereo mode or 1000 W RMS in mono bridge
mode.
Stereo mode
In this application, a low impedance stereo amplifier is used together with the TF-500 to get two 100 or 70
V lines.
Place the STEREO/BRIDGE MONO selector in the STEREO position.
Connect both of the low impedance amplifier stereo output channels to INPUT 1 or INPUT 2.
Connect the speaker line to the speaker output. Use the 100 or 70 V line output in accordance with the type
of speakers you are going to connect. Use only one of the output lines.
All the speakers must be connected in parallel and the sum of the power of all the speakers must not exceed
the power supplied by the TFA-500.
