Frequently Asked Questions - TR 206 LD Systems

How to connect the TR 206 to my amplifier?

Use the supplied Euroblock connectors. Connect the amplifier's speaker output (low impedance) to the INPUT of the TR 206, respecting the available impedances (2, 4 or 8 Ω). For each channel, connect the COM terminal and the chosen impedance.

What is the maximum power per channel?

The permissible power per channel is 60 W for TR 206 and 120 W for TR 212. Do not exceed this value to avoid damaging the transformer.

Can I use the TR 206 with a class D amplifier?

Yes, provided that the class D amplifier allows connection to an external transformer. If in doubt, contact the amplifier manufacturer. A warning is given in the manual.

What are the available output voltages?

The outputs provide a constant voltage of 25 V, 70 V or 100 V depending on the connection on the OUTPUT terminal. Choose the voltage suitable for your distributed speaker installation.

How to mount the TR 206 under or on a table?

Use the two mounting plates supplied. Locate the recesses with M3 threaded holes on the housing, screw the plates with the included countersunk screws, then attach the assembly to the table with screws not supplied. For tabletop mounting, first remove the rubber feet.

What to do if the sound is distorted or low?

Check that the selected input impedance matches that of your amplifier. Ensure the amplifier power does not exceed 60 W per channel. Check the Euroblock connections and cable condition.

Is it possible to repair the TR 206 myself?

No, the device contains no user-replaceable parts. Any repair must be carried out by qualified personnel authorized by the manufacturer. Unauthorized opening may cause electric shock risk and void the warranty.

How to clean the transformer?

Use a clean, damp cloth to clean the housing surfaces. Ensure no moisture enters the interior. Do not use solvents, abrasives, or cleaners. Ventilation openings should be dusted regularly.

What is the warranty of the TR 206?

The manufacturer's warranty is detailed in the manufacturer's declarations available on the Adam Hall website. See page https://cdn-shop.adamhall.com/media/pdf/MANUFACTURERS-DECLARATIONS_LD_SYSTEMS.pdf or contact your dealer.

Can I use the TR 206 outdoors?

No, the device is designed for indoor use. It is not waterproof and has no protection rating against water or dust. Use it in a dry, weather-protected environment.

INTRODUCTION

TR 206

Part of the TICA ^® series, the TR206 is a two-channel 60W loudspeaker transformer designed to take a low impedance amplifier signal and convert it to a constant voltage loudspeaker line. This allows a conventional low impedance amplifier to be used to drive multiple loudspeakers on each of its outputs, when used with loudspeakers that have a constant voltage connection.

Measuring 142 x 44 x 226 mm, its convenient form factor and included mounting plates allow it to be installed discreetly almost anywhere. Alternatively, it fits into 1/3 19-inch rack. Use the optional rack tray to slot several TICA ^® series products alongside each other and build a system to your exact requirements, using minimal rack space.

TR 212

Part of the TICA ^® series, the TR212 is a two-channel 120W loudspeaker transformer designed to take a low impedance amplifier signal and convert to a constant voltage loudspeaker line. This allows a conventional low impedance amplifier to be used to drive multiple loudspeakers on each of its outputs, when used with loudspeakers that have a constant voltage connection.

Measuring 142 x 44 x 226 mm, its convenient form factor and included mounting plates allow it to be installed discreetly almost anywhere. Alternatively, it fits into 1/3 19-inch rack. Use the optional rack tray to slot several TICA ^® series products alongside each other and build a system to your exact requirements, using minimal rack space.

CARE, MAINTENANCE AND REPAIR

In order to ensure the long-term, proper functioning of the device, it must be regularly cleaned and, if necessary, serviced. The servicing requirement depends on the intensity of use and the environment in which it is used.

We recommend a visual inspection before each operation. Furthermore, we recommend carrying out all the applicable maintenance measures specified below once every 500 operating hours or, in the case of a lower intensity of use, at the latest after one year. Warranty claims may be limited should defects result from inadequate service and maintenance.

CARE (CAN BE PERFORMED BY THE USER)

WARNING! Before carrying out any care and maintenance work, the power supply and, if possible, all device connections must be unplugged.

NOTE! Improper care can lead to impairment or even destruction of the device.

1. Housing surfaces must be cleaned with a clean, damp cloth. Make sure that no moisture can penetrate the device.
2. Air inlets and outlets must be regularly cleaned of dust and dirt. If compressed air is used, make sure that damage to the device is prevented (e.g. fans must be blocked in this case).
3. Cables and connectors must be cleaned regularly and dust and dirt must be removed.
4. In general, no cleaning agents or abrasive agents may be used, as they may damage the surface finish. Solvents in particular, such as alcohol, can impair the function of housing seals.
5. Devices must generally be stored dry and protected from dust and dirt.

MAINTENANCE AND REPAIR (BY QUALIFIED PERSONNEL ONLY)

DANGER! There are live components in the device. Even after disconnecting the mains connection, there may still be residual voltage in the device, e.g. due to charged capacitors.

PLEASE NOTE! There are no user-serviceable assemblies in the device.

PLEASE NOTE! Maintenance and repair work may only be carried out by adequately qualified personnel. If in doubt, consult a specialist workshop.

PLEASE NOTE! Improperly performed maintenance work may affect warranty claims.

PLEASE NOTE! For conversion or retrofit sets provided by the manufacturer, it is essential to observe the included installation instructions.
