An amplifier powered by battery or with transformer plugged into the electric current., the Delan THA allows Delan headsets to be made compatible with any type of telephone presently on the market.

L’amplificatore Delan THA consente di rendere compatibile le cuffie Delan con qualsiasi tipo di telefono presente sul mercato.

While its main function is to amplify the incoming signal and to optimize the transmission signal, the THA offers even more:

• Mute button to put the speaker on hold and thus silence the microphone of the operator.
• Button for the operator to select the use of the headset or the receiver.
• Control of the incoming volume.

Three ways of using the Training function

1. With the training microphone mute;

2. With the operator’s microphone mute;

3. With both training and operator’s microphones mute (only listening);

Control of the transmission volume

The THA amplifier has a selector with two different positions which automatically shows the polarity. Thanks to this function, the THA finds and uses the best configurations to achieve the highest quality transmission sound possible.
