AMT TDD-3 architecture: 

9

 

Analog input and output circuits. 

9

 

Fully digital circuit of original sound delay. 

9

 

High-quality analog-to-digital and digital-to-analog converters. 

9

 

Fully functional digital control (except for the signals mixing and their levels 
control). 

9

 

Analog circuits for the signals levels and phases changing. 

9

 

Another circuits for signals mixing. 

9

 

Application of high-quality film capacitors. 

 

Use only MONO-JACKS for TDD-3 connections.  
 

 

 

Important!  Like other top-class devices AMT TDD-3 is 
sensitive to power source quality. We insist that you use 
either the power adapter conforming to the quality 

requirements (recommended adapter: 

АМТ

 PSA0109 9V/800mA) or 

9V 6F22 battery. 
 
 

 
 
Before you start:  

For safe transportation the device was carefully packaged by the manufacturer. 
However, if the cardboard packaging is damaged you should immediately inspect 
the device for the absence of external damages.   
 

¾

 

In case of damages do NOT SEND the device to manufacturer, 
but inform the seller or transport agency, since otherwise you 
will lose the right to damage compensation. 

 

¾

 

In order to avoid damages during storage and transportation 
always use original packing. 

 

¾

 

Do not allow children to play with the device and packaging 
materials. 

 

¾

 

Please, recycle all packing materials in the way harmless to 
the environment. 

 

¾

 

In order to avoid the device overheating provide a sufficient air 
flow around it; do not cover it and do not place near other heat 
emitting devices. 

 

¾

 

Device operation near powerful radio transmitters and sources 
of high-frequency signals can result in appreciable 
deterioration of sound. In this case increase the distance 
between the device and the transmitter and use screened 
cables for all interconnections.  
 

 
CAUTION! 
Please be aware that high volume can harm your hearing and / or 
damage the dynamic heads of your acoustic system. Before turning 
the device on rotate Volume controls to extreme left position 
(counter-clockwise). Always try to adhere to moderate volume level. 
 

 
 
Specifications:  
 

Use only external devices and accessories recommended by the 
manufacturer. 

 

 

 

Powering the device from battery and power adapter  

AMT TDD-3 is powered both by battery (DC 9V 6F22) and DC 9V external power 
adapter (the required specifications are shown in Specifications). 
If the device is 

battery

 powered, the device is switched on only after insertion of  

MONO 

JACK into INPUT

 located on the river and all of the device. This is the 

way of saving your battery resource. 
 When the device is powered by power adapter, the battery is turned off. In this case 
the device switches to the power adapter use at once; the presence of 

JACK in 

INPUT is not necessary

  

Attention! In order to save the battery resource, it is recommended 
to use external power adapter whenever possible.
