  4. GENERAL ARCHITECTURE

  5. 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.

  6. 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.

  7. 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. Use various user access levels.

  15. Audio Processing – General features

  16. Audio Processing – General features • Digiplexer 2/4: the first processor that operates at : • 192 kHz sample rate for main processing stages • 1.5 MHz sample rate for the final limiter • Processing delay is non-audible (less than 5ms). • A high pass filter can be set from 1 to 200Hz in order to control sub bass.

  17. Audio Processing – Automatic Gain Control • Predictive AGC (Automatic Gain Control): • Corrects large audio level variations (up to 30dB) • Without any pumping effect • With a Gatefunction The AGC will not increase the level in case of silence (configurable threshold)

  18. Audio Processing – Equalization and Audio Enhancement • With the 4-band* parametric equalizer: • Create your own sonic signature. • Control how the bands will work. • Use the Bass FX and the Treble FX to dynamically enhance your bass and high frequencies. • Full mode allows access to more parameters. (on/off, frequency, filter quality, gain) * Even on 2-Band version

  19. Audio Processing – Stereo Enhancement • Stereo FX • Enhance your audio’s stereo effect. • A Stereo Limiter insures reception stability by controlling the L-R MPX signal – minimal multipath effects.

  20. 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.

  21. 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

  22. 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)

  23. 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

  24. 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

  25. 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)

  38. STEREO ENCODING

  39. Stereo Encoding • Control your modulation precisely (+/-75kHz): • 1.5Mhz FM Clipper (High sampling rate never reached before!) • Use the Virtual Composite Clipper to keep a high quality MPX signal. • Control your MPX Power (ITU-R412): • MPX Power Limiter that operates on the audio processing stages for better results. • Predictive Power calculation (for instantaneous MPX power display and limitation) • MPX Power Limiter and Virtual Composite Clipper are also active on any audio output configured in FM mode.

  40. Stereo Encoding • DSP technology and perfect synchronization of all subcarriers. • Audio, Pilot and RDS signals are produced in the same unit. • Stereo Encoder, highly over-sampled for amazing stereo performance. • High Quality Composite Signal • means higher audio quality for listeners • Digital 15kHz filter offers very high performance (better 19kHz stability, L-R quality…) • Stereo encoder performance that enables the audio bandwidth to be extended to 17kHzwithout affecting the 19kHz or L-R signals.

  43. AUDIO BACK UP & SECURITY

  44. Audio Backup • The Digiplexer 2/4 is an Audio Backup device that can play an audio file in case of silence on other inputs. • Play audio files previously uploaded (remotely via FTP). • Use the Backup as a 3rd audio input. • Stream the audio from a remote source • Use standard audio formats. • MP3 • Wave • Auto-switch between 3 audio inputs (analog, digital and backup audio) • Configure delay and threshold for silence detection. • Choose the order of priority between the 3 inputs • Configure crossfades for audio input switchovers. • Fade in / fade out, for smoother audio transitions

  45. 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.

  46. 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!
