Lyngdorf Audio TDA 2200 owner manual e. ADC Level - Otional, f. Communication

e. ADC Level - Otional

The ADC Level menu is accessible when the optional analog input module (A/D converter) is installed. Here it is possible to choose between the inputs on the analog input module and assign each input a LOW and HIGH level. When the LOW level is selected no amplification of the analog inputs is performed, whereas when the HIGH level is selected an amplification of +6 dB is performed.

f. Communication

The sub menus accessible in the Communication menu are:

•Comm Speed

•Comm Address

The Communication setting signals the TDA 2200’s identity to the PC interface or other Lyngdorf products. In master mode the amplifier setting is normally 1, and the addresses 2-99 can be used for individual slave amplifiers, but nothing is restricted. In the menu the current address and the new address is shown, The Up/Down keys can be used for changing the new setting, and a new selection is stored with Enter which also exits the menu again. Pressing Menu again exits the menu without changing the current settings. The PC software must know the address of the TDA 2200 in order to communicate with it.

The Comm Speed setting is the RS232 Link interface speed. The default setting is 57600 baud. With different PC’s and different lengths of cables the settings can be changed for faster communication to 9600 or 115200 baud. If a multi-amplifier set-up is installed with Master/Slave communication, a smaller delay can be observed when using higher speeds.
