1.5 Design
The TDA-500 is installed in standardized 19 "racks in accordance with DIN 41494.
The TDA-500 has two independent amplification channels with a power of 250 W each
(when operating in two-channel mode) or one independent amplifying channel with a power
of 500 W (when operating in a single-channel mode).
The TDA-500 is powered from a 230 V AC power supply. Additionally, it is possible to
connect a backup power supply in the form of a 48 V DC power supply. In the event of a
power failure, the TDA-500 automatically switches to a backup power supply.
The TDA-500 design provides:
– availability of controls and indication TDA-500. TDA-500 control and indication
bodies are located on the front panel;
– availability of protection against overvoltage, short circuit, no-load and
overheating;
– availability of mounting holes for installation in a 19 "rack;
– convenient access to the elements involved in the operation;
– the presence of potentiometers to adjust the volume of sound, high and low
frequencies for each channel;
– presence on the front panel of the TDA-500 case with LED indication for each
channel.
