General architecture – On the transmitter site Use Digiplexer 2/4 as a backup processor (i.e. 2 band version) or main one (i.e. 4 band). Guarantee your audio with the Input/Output management and the embedded Audio Backup. Create high quality signals: Audio, RDS, MPX. Keep total control of the site with the I/O Remote Control functions and ScriptEasy Software.
General architecture – In the Studio Use the Digiplexer 2/4 as a main Audio Processor at a Studio. Process the sound for any format (FM, Web stream, HD radio…) Encode your RDS data locally. Configure a Monitor Audio Output for local listening.
General architecture – Studio and Tx sites Use the Digiplexer 2/4 as your main audio Processor at the Studio. (i.e. 4 band version) Use a 2 band version at each transmitter site to generate consistent high quality signals (MPX, RDS…) Configure each Digiplexer 2/4 remotely via TCP/IP.

Audio Processing – 2 or 4 Bands Process • Multi-Band Processing • A unique algorithm controls the gain for each band. • ‘Fidelity’ parameter enables control of audio coloration. (Purist / Processed) • Sound Impact System - a revolutionary algorithm to preserve dynamic and peak attack perception. • Use easy mode, or fullmode to access more parameters.
Audio Processing – 2 or 4 Bands Limiter • Multi-band Limiter • Predictive function guarantees perfect peak control without the weaknesses of standard limiters. • Mix function enables control of the balance between each band. • Use easy mode, or fullmode to access to more parameters
Audio Processing – Final Limiters • HF limiter controls HF energy • FM limiter is a revolutionary 1.5 MHzclipper(older processors work at 768kHz) • A clipper that works at 1.5MHz, a sampling rate never reached before! • Virtual Composite Clipper • HD limiter for high qualitydigital applications (HD, DAB, DRM, Webstream...) • Look ahead limiter • Low processing delay (5 ms)
Audio Processing – Final Limiters • Both peak processing paths can be used at the same time: • FM limiter for FM applications • HD limiter for digital radio applications
Audio Processing – Additional Features • Compare Function • Compare instantly current settings with other presets. • Factory and User Preset management • Keeps a complete history of your changes! • Your old settings will never be lost… • Undo / Redo function • Cancel any modification • Compare quickly how any new setting impacts the sound. • Each processing stage or parameter can be switched on/off for easy audio comparisons ON/OFF
Audio Processing – Additional Features • Basic mode • (easy configuration) • User Level (Easy/Full) • Access Controlled by Password • Various user access levels • Super Administrator (full access) • Broadcasters (no access to preset parameters) • Users (no access to output levels) • … • Full mode • (all parameters available)

Audio Backup – Security Reliability and Security: With the Digiplexer, you will always stay on the air! In case of Audio Signal Loss: • Auto-Switch (analog, digital and internal backup audio inputs): • Backup modeswitchesto a secondary input if silence is detected on the primary (configurable threshold and delay) • Priority mode switches to a main input when audio is detected. (configurable threshold and delay – useful for local programs) • Embedded Audio Backup • Play audio files previously uploaded (remotely via FTP). • Stream the audio from a remote server via TCP/IP • Use the Backup as a 3rd audio input.
Audio Backup – Security Reliability and security: With the Digiplexer, you will always stay on the air! In case of Power Loss: • Hardware Audio Bypass (AES-AES and analog-analog) • 2 second Reboot! (from power on to on air with active audio processing) In case of system crash: • You stay On the Air: • An Internal controller will automatically reboot the system, but the audio card continues to run! • The Sound4 DSP audio card is independent of the system: • Plug in the Digiplexer:you are On the Air in only 2 seconds!
