Description
- The amplifier "YENISEY D10.0" is designed to amplify the signal of the nominal level 0.775V (0dB) coming from the source of the sound program to the level of 240V (50dB) at the nominal load
- The amplifier is made in the form of a 19" rack, which houses a set of blocks providing a power of 10000 W
- Amplifier output transformer balanced, protected by a fusible link
- The amplifier is powered from a three-phase AC network with a voltage of 3x380V, 50Hz, with the obligatory connection of the neutral and ground wires.
- The amplifier has a protection system:
Thermal protection circuit implemented in the power amplifier unit
Circuit for monitoring the health of fuses in the audio signal path
Overload protection circuit in each PSU (power supply)
It is provided to turn off the amplifier when any of the phases is lost
- Wired broadcasting networks
- As part of warning systems for civil defense and emergencies
- As part of systems used to conduct vibration tests
