AEV STARGATE EVO Stereo & RDS Encoder



Stargate Evo is a digital stereo encoder and RDS coder for broadcast applications that has been designed using highly innovative technology.
The result is the most advanced that a stereo broadcasting system can offer, with an exceptional array of features.
Besides guaranteeing excellent stereo separation between channels, AEV’s Digital Stereo Encoder ensures a transparency of sound never before reached, whilst maintaining exceptional stability.

Stargate can be installed instantly and can be matched perfectly to any transmission system without calibration.
Stargate can be installed instantly and can be matched perfectly to any transmission system without calibration.The new Stargate Evo multicoder is powered with the latest generation
DSP, responds to the new operational needs of audio signal management for FM stations.
Inputs section: balanced analogue stereo input, digital AES/EBU, digital optical and also MPX and RDS signals coming from outside.
Stargate Evo has a color TFT LCD display; on the home page the levels of the inputs are displayed, the input selected as Main and the MPX output level.
Input switch management. The INPUT SETUP page determines: the priority scale of the inputs, named as MAIN, SUB1 and SUB2, the exchange activation time and the exchange intervention threshold.
Stereo Coder with digital synthesis, with MPX signal level adjustment, 19 KHz pilot, digital clipper activation, input levels of any external RDS signal and internally generated RDS signal.

The Stargate Evo is also fully equipped with an RDS signal decoder; through this section it is possible to decode the data of an external RDS signal, decide which ones to keep and which to modify locally, and then regenerate the RDS data package to be supplied to the local FM transmitter. The RDS Decoder also allows the PI code contained in the external RDS signal to be monitored, if the PI code is different from the one programmed, it is possible to activate the exchange from the external MPX signal and the internally generated one.
The GPI/O port takes the status of the machine’s inputs to the outside, for a simple interface with the transmitters’s telemetry.
The machine can be controlled via ethernet thanks to the internal web server, this solution frees the user from installing PC software; in addition, the Web Server can be set as CLIENT, in case of insertion in a LAN network, or as a SERVER, if you want to directly connect a PC with an Ethernet network cable.
It is possible to activate a password that limits access to the machine, inhibiting the modification of the setup parameters to unauthorized personnel.
