The superb stand-alone stereo encoder combining look-ahead and band-limited clipping techniques with latency as low as 2ms and full overshoot limiting and extremely tight peak control in both the left/right and composite baseband domains, to control STL-induced overshoots while minimizing artifacts. The 5518 is the ideal choice for network broadcasters who process with an FM audio processor (like Orban Optimod FM 8600) at the network origination point and who need a processor at every transmitter to eliminate network STL overshoots.
The 5518 includes a full-featured RBS/RBDS generator at no additional charge. The generator supports dynamic PS. It can be controlled via the 5518 presets and an ASCII terminal server that can be connected to automation to support, for example, displaying title and artist.
The built-in defeatable ITU BS412 multiplex power controller acts on all outputs to meet even the most stringent European government regulations include a full spectral protection of subcarriers and RDS/RBDS regardless of the amount of composite limiting.
A 10MHz frequency reference input allows the stereo pilot tone frequency to be locked to GPS or another high-accuracy frequency standard. This improves the performance of single-frequency networks in areas where coverage of the transmitters overlaps.
The stereo encoder's stereo sub-channel modulator can operate in normal double sideband mode and in an experimental compatible single sideband mode (SSB/VSB) that is offered to enable users to compare and assess the two modes.
Analog fallback to digital control that allows silence sense to switch the active input from analog to digital if silence is detected in the analog input signal but not on the digital input signal.
This function works vice versa as well on both analog and digital AES input.
