Elti has developed ....

... all in one solution...

The Elti front access series is the product of many years experience in analogue and digital technology. Providing a custom solution for special needs, this device offers a smooth changeover from analog to digital broadcasting by automatically detecting the type of the input signal and re-transmitting it accordingly. All recent settings for digital and analogue modes are saved so you can transmit with the same settings when switching over.

With a special high precision oscillator we are able to provide outstanding performance in both analogue and digital transmittion. The use of Elti power amplifiers enables you to have a perfect solution for analogue and digital network in one device. Protection circuits and microprocessor operated controls guarantee maximum reliability. The whole series is fitted with remote software upload through internet or WEB server for management and control.
