The front panel of the TDA-500 contains:
1 –indicator «BATTERY» (red) – indication of operation mode from a 48 V DC power
source or battery operation;
2 – indicator «MAINS» (green) – indication of the mode of operation from the
alternating current with a voltage of 230 V;
3 – indicator «FAULT» (red) – indication of faults in the amplifier operation: overheating,
short circuit on the line or exceeding the permissible load of Channel A;
4 –indicator «OK» (green) – indication of work in the active mode of Channel A;
5 – indicator «CLIP» (red) – indication of
С hannel A overload;
6 – potentiometer «BASS» – adjustment of low frequencies of Channel A;
7 – potentiometer «TREBLE» – adjustment of high frequencies of Channel A;
8 – potentiometer «VOLUME» – volume control of Channel A;
9 – indicator «SIGNAL» (yellow) – indication of the input signal on Channel A.
For Channel B, the front panel has similar indicators and potentiometers.
The rear panel view of TDA-500 is illustrated at Figure 3.

Figure 3 – The rear panel view of TDA-500
The rear panel contains:
1 – connector «AC IN» – AC power plug for connecting the power cable. In the
connector housing there is a fuse 6 A, designed to protect the circuits of the electric network
from short-circuit currents in case of failure TDA-500;
2 – connector «DC IN» – two-pin plug, input 48 V DC;
3 – connector «OUT B» – three-pin plug,
output С hannel B;
