  • Page 5: Introduction

    INTRODUCTION E N G 2 INTRODUCTION Thank you for choosing this easy to use, digital 5 band audio processor for Fm band and satellite radio broadcasting. The processing is based on 5 compressors for the Bass, Mid1, Mid2, Mid3 and High audio bands. Several, easily modified parameters strongly affect the colour and richness of the sound.
  • Page 6 PC software interface. The Falcon 35 MKII features two hardware bypass: the first one connects the Right / Left audio input to the Right / Left audio output (on XLR connectors) in the event of Main AC failure. The second hardware bypass directly connects the AUX-1 Bnc to the OUT-1 Bnc, also in the event of Main AC failure.

  • Page 7: Available Versions

    AVAILABLE VERSIONS E N G 3 AVAILABLE VERSIONS 3.1 FM VERSION Thanks to its state-of-the-art digital technology, the processor integrates, as an option, a Stereo MPX coder (including composite clipper) and a RDS coder. The digital MPX stereo coder (optional) represents the ideal ‘final touch’ of processing. As it is directly built-in, it is totally harmonized with all other signal processing stages and ensures the best results in signal density while adhering to modulation limits.

    I/O CALIBRATION AND SYSTEM SETUP E N G 19.3 MONO / STEREO INPUT OPERATION (ST VERSION ONLY) The ‘INPUT MODE’ menu selects the mono versus stereo operation of the input. You can chose between a full stereo operation or a Mono mode where Left and Right input channels are mixed together before going through the main processing stages.

  • Page 49: Agc Speed

    I/O CALIBRATION AND SYSTEM SETUP E N G The Phase Rotator stage performs 1 msec Group Delay at low frequencies in respect of medium frequencies. This results in a phase rotation centered on 600 Hz frequency. 19.5 AGC SPEED One of the most important processor function is the Automatic Gain Control (AGC) system, which compensates for variations in the input level to keep the signal at 0 dB.

  • Page 50: Agc Mode

    I/O CALIBRATION AND SYSTEM SETUP E N G 19.6 AGC MODE The AGC Mode menu mainly serves to regulate the maximum level gain recoverable by the AGC (MaxGain) and its intervention time (with reference to the interval –3 to 3 dB within which the AGC works at one quarter of the user-set speed).

  • Page 51: Analog Output Pre-Emphasis

    I/O CALIBRATION AND SYSTEM SETUP E N G 19.7 ANALOG OUTPUT PRE-EMPHASIS The XLRs analog output is intended for applications requiring discrete L/R processed audio. The frequency characteristic can follow a selected pre-emphasis curve, with or without subsequent de-emphasis. The factory-default setting is with pre-emphasis engaged, accordingly to the destination country (50 or 75 uSec).

  • Page 52: Digital Audio Output Pre-Emphasis (St Version Only)

    I/O CALIBRATION AND SYSTEM SETUP E N G Remarks: Only one pre-emphasis must be kept active in a transmitting chain. It is highly recommended to use the pre-emphasis within the processor and turn off the one generated by external TX or MPX Coders. The processor’s pre-emphasis may be disabled on the analog audio outputs, but NOT on the MPX output, which remains 50 or 75 uSec pre-emphasized at all times.

  • Page 53: Analog Output Level

    I/O CALIBRATION AND SYSTEM SETUP E N G 19.9 ANALOG OUTPUT LEVEL You can adjust the analog audio output level (XLR connectors) through the Output Level control: DEFAULT SCREEN OUTPUT CALIBRATION menu OUTPUT LEVEL page The Output Level parameter expresses the peak value (in dBu) achieved by the audio output signal (which therefore corresponds to the maximum frequency deviation).

    I/O CALIBRATION AND SYSTEM SETUP E N G 19.15 POWER LIMITER CONTROL ITU 412 (ST VERSION ONLY) The ITU BS-412 regulation aims to reduce the density of the modulated signal while maintaining the same peak deviation level in order to ensure minimal or limited co-channel interference. The BS-412 definition says: “It is assumed that the maximum peak deviation of +/- 75 kHz is not exceeded.

  • Page 87: Hints And Tips About Dynamic Ps Mode

    Using the RDS SECTION (FM version ONLY) E N G 23.7 HINTS AND TIPS ABOUT DYNAMIC PS MODE When programming PS durations in Dynamic mode, two ‘gold’ rules should be taken into account. They are related to the ‘physics’ of RDS channels and are completely independent from RDS encoder architecture. WARNING: if the PS is constantly changed (as in the PS Scrolling mode), it is possible that some receivers will display a mixture of old and new PS message on the same display.

  • Page 88: Alternative Frequencies List

    Using the RDS SECTION (FM version ONLY) E N G 23.8 ALTERNATIVE FREQUENCIES LIST The list(s) of alternative frequencies give information on the various transmitters broadcasting the same programme in the same or adjacent reception areas, and enable receivers equipped with a memory to store the list(s), to reduce the time for switching to another transmitter.

  • Page 89: Af Methods A And B

    Using the RDS SECTION (FM version ONLY) E N G 23.9 AF METHODS A AND B There are two ways to transmit lists of alternative frequencies: Method A and Method B. In both cases the lists should include only those frequencies for the nearest transmitters and repeaters (with overlapping coverage areas).
  • Page 90 Using the RDS SECTION (FM version ONLY) E N G METHOD B As mentioned earlier, Method B is used with high numbers of alternative frequencies and/or when the transmitter also has frequencies that broadcast different radio program at various times of day (splitting, local programming, etc.).
