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.

-5-

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.

-6-

Two speaker zones

In this application, two ampliﬁers in low impedance mono bridge mode are used together with the TFA-500 to

get 2 independent 100 or 70 V lines.

Place the STEREO/BRIDGE MONO selector in the STEREO position.

Connect the mono output channel from each low impedance ampliﬁer to the INPUT 1 and INPUT 2 inputs.

Connect the speaker line to the speaker output. Use the 100 or 70 V line output in accordance with the type of

speakers that you are going to connect. Only use 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.

-7-

Mono bridge mode

In this application a low impedance ampliﬁer is used in mono bridge mode together with the TF-500 to

achieve 2 x 100 or 70 V lines with the same signal.

Place the STEREO/BRIDGE MONO selector in the BRIDGE MONO position.

Connect the mono output channel from the low impedance ampliﬁer to the INPUT.

Connect the speaker line to the speaker output. Use the 100 or 70 V line output in accordance with the type

of speakers that you are going to connect. Use just 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.
