  • Page 27: Section 1 Introduction

    Because OPTIMOD-FM incorporates several audio processing innovations exclusive to Orban products, you should not assume that it can be operated in the same way as less sophisticated processors. If you do, you may get disappointing results.

  • Page 28: User-Friendly Interface

    If you wish to place level protection prior to your studio / transmitter link (STL), use the Orban Optimod 6300 or Optimod-PC 1101 or 1101e. These processors can be ad- justed so that they substitute for the AGC circuitry in OPTIMOD-FM, which is then defeated.

  • Page 29: Absolute Control Of Peak Modulation

    OPTIMOD-FM DIGITAL INTRODUCTION Absolute Control of Peak Modulation • The 5700i provides universal transmitter protection and audio processing for FM broadcast. It can be configured to interface ideally with any commonly found transmission system in the world, analog or digital. •...

  • Page 30: Flexible Configuration

    • OPTIMOD-FM 5700i is supplied with analog and AES3 digital inputs and outputs. The digital input and the two digital outputs are equipped with sam- ple-rate converters and can operate at 32 kHz, 44.1 kHz, 48 kHz, 88.1 kHz, and 96 kHz sample rates.
  • Page 31 FM exciter. Both the 5700i and 5700iFM offer this feature, making it con- venient to use the 5700iFM in dual-processor HD installations where the digital channel receives independent processing from a processor like Orban’s Optimod- DAB or Optimod-PC. Each output (Analog, Digital 1, Digital 2, Composite) can be independently configured to emit the delayed or undelayed signal.

  • Page 32: Adaptability Through Multiple Audio Processing Structures

    A special Two-Band preset creates a no-compromise “Protect” function that is functionally similar to the “Protect” structures in earlier Orban digital processors. • The 5700i can increase the density and loudness of the program material by multiband compression, limiting, and clipping—improving the consistency of the...

  • Page 33: Upgradeable To 8600S

    Via a purchased upgrade kit, the 5700i can be upgraded to full 8600S func- tionality via a network connection without removing the unit from the rack. This upgrade adds Orban’s exclusive MX limiter technology, which uses a built-in psychoacoustic model and other advanced signal processing techniques to add about 2.5 dB more high frequency power handling capability, lower distortion,...

    OPTIMOD-FM DIGITAL INTRODUCTION Input/Output Configuration The 5700i offers: • One digital AES left/right input on XLR that can also be used as a sync reference to lock the digital output sample rate and the 19 kHz pilot tone frequency. • One AES3id input on BNC that can be used as an audio input in “ratings en- coder Loopthrough mode.”...

  • Page 36: Analog Left/Right Input/Output

    1-10 INTRODUCTION ORBAN MODEL 5700i Level control of the AES3 input is accomplished via software control through System Setup (see step 5 on page 2-28) or through PC Remote. Both analog and digital outputs are active continuously. The 5700i’s output sample rate and 19 kHz pilot tone frequency can be locked to the 5700i’s internal crystal clock, to the sample rate present at its AES3 input, or to a...

  • Page 37: Subcarriers

    1-11 OPTIMOD-FM DIGITAL INTRODUCTION Subcarriers The stereo encoder has two unbalanced 600Ω subcarrier (SCA) inputs with rear- panel BNC connectors to accept any subcarrier at or above 23 kHz. The subcarriers are mixed into each composite output and their level is not affected by the compos- ite level control for that output.

  • Page 38: Computer Interface

    1-12 INTRODUCTION ORBAN MODEL 5700i The remote control of overshoot compensation and SCA modulation (see page 2-43) is not latching. You must supply a continuous current to the programmed remote input to hold the gain at its compensated level. Use...

  • Page 39: Rj45 Ethernet Connector

    1-13 OPTIMOD-FM DIGITAL INTRODUCTION RJ45 Ethernet Connector The 5700i can be connected to a 10, 100, or 1000 Gb/sec Ethernet network that sup- ports the TCP/IP protocol and is connected via CAT5 or CAT6 cabling. See Networking and Remote Control on page 2-44 for more information. Wordclock/10 MHz Sync Reference Input The sync reference input appears on a female BNC jack grounded to the 5700i’s chassis.

  • Page 40: Best Location For Optimod-Fm

    1-14 INTRODUCTION ORBAN MODEL 5700i 1) The system group delay must be essentially constant throughout the frequency range containing significant energy (30-15,000Hz). If low-pass filters are present, this may require the use of delay equalization. The deviation from linear-phase must not exceed ±10° from 30-15,000Hz.

  • Page 41: If The Transmitter Is Accessible

    1-15 OPTIMOD-FM DIGITAL INTRODUCTION the STL. Then feed the output of the STL receiver directly into the transmitter’s ex- citer with no intervening processing. If an uncompressed AES3 digital link is available to the transmitter, this is also an ex- cellent means of transmission, although it will not pass the effects of the 5700i’s composite processor (if you are using it).

  • Page 42: Transmission From Studio To Transmitter

    You will achieve a louder sound on the air, with better control of peak modulation, than if you use most external stereo encoders. An exception is Orban’s 5518 stereo encoder, which does not add overshoot and contains its own overshoot limiter and composite limiter equivalent to the one in the 5700i when operated in its stand-alone stereo encoder mode.

  • Page 43: Digital Links

    75μs preemphasis must then be applied to the codec’s output signal. This usually oc- curs in the FM transmitter’s stereo encoder or in a stand-alone stereo encoder like an Orban 5518. Some links may use straightforward PCM (pulse-code modulation) without lossy da- ta reduction.

  • Page 44: Composite Baseband Microwave Stls

    1-18 INTRODUCTION ORBAN MODEL 5700i kHz, it can be passed without additional overshoot by equally well by any link with 44.1 kHz or higher sample frequency. Currently available sample rate converters use phase-linear filters (which have con- stant group delay at all frequencies). If they do not remove spectral energy from the original signal, the sample rate conversion, whether upward or downward, will not add overshoot to the signal.

  • Page 45: Dual Microwave Stls

    Nevertheless, in a dual-microwave system, the 5700i is usually located at the main FM transmitter and is driven by the microwave receivers. One of Orban’s studio level control systems, such as the 1101e, protects the microwave transmitters at the studio from overload.

  • Page 46: Analog Landline (Ptt/Post Office Line)

    Some consultants presently offer modifications to minimize or eliminate this prob- lem. If your exciter or STL has this problem, you may contact Orban Customer Service for the latest information on such services. Analog Landline (PTT/Post Office Line) Analog landline quality is extremely variable, ranging from excellent to poor.

  • Page 47: About Transmission Levels And Metering

    1-21 OPTIMOD-FM DIGITAL INTRODUCTION In addition, at least one other mechanism can cause the noise to become audible at the radio. OPTIMOD-FM’s multiband limiter performs an “automatic equalization” function that can radically change the frequency balance of the program. This can cause noise that would otherwise have been masked to become unmasked because the psychoacoustic masking conditions under which the masking thresholds were originally computed have changed.

  • Page 48: Transmission Levels

    1-22 INTRODUCTION ORBAN MODEL 5700i Fig. 1-1: Absolute Peak Level, VU and PPM Reading The studio engineer is primarily concerned with calibrating the equipment to pro- vide the required input level for proper operation of each device, and so that all de- vices operate with the same input and output levels.

  • Page 49: Line-Up Facilities

    1-23 OPTIMOD-FM DIGITAL INTRODUCTION Line-Up Facilities Metering of Levels and Subjective Loudness The meters on the 5700i show left/right input levels and composite modulation. Left and right input level is shown on a VU-type scale (0 to –27 dB), while the metering indicates absolute instantaneous peak (much faster than a standard PPM or VU me- ter).

  • Page 50: Built-In Calibrated Line-Up Tones

    1-24 INTRODUCTION ORBAN MODEL 5700i integration time of the Short-Term Meter is always 3 seconds, while the Integrated Meter uses silence gating and its integration time is user-adjustable to 10, 20, 30, or 60 seconds. Because the meter is always monitoring program material, it integrates the previous 10, 20, 30, or 60 seconds of program material and weights all program material equally within the specified time window.

    1-25 OPTIMOD-FM DIGITAL INTRODUCTION driven equipment will undo the effect of the 5700i’s internal de-emphasis, so the 5700i’s output level should be adjusted such that the tone produces 100% modula- tion of the transmission link as measured after the link’s pre-emphasis filter. At 100Hz, switching the de-emphasis out or in will have negligible effect on the level appearing at the 5700i’s left and right audio outputs.

  • Page 52: Low-Delay Monitoring

    1-26 INTRODUCTION ORBAN MODEL 5700i • prevents the bass clipper from switching to Medium mode whenever speech is detected. By constraining the system in these ways, it ensures that the delay is always 13 ms. Switching the B to LLH (from any other mode) removes five milliseconds of delay from the signal path.

    OPTIMOD-FM DIGITAL TROUBLESHOOTING Section 5 Troubleshooting Problems and Potential Solutions Always verify that the problem is not the source material being fed to the 5700i, or in other parts of the system. RFI, Hum, Clicks, or Buzzes A grounding problem is likely. Review the information on grounding on page 2-11. The 5700i has been designed with very substantial RFI suppression on its analog and digital input and output ports, and on the AC line input.

    Many commercial monitors have this problem, but most of these problem units can be modified to indicate peak levels accurately. Orban uses the Belar “Wizard” series of DSP-based monitors internally for testing, because these units do not have this difficulty.

    STL may only be 70-75 dB. In this case, it is wise to use the Orban 8200ST Studio AGC to perform the AGC func- tion prior to the STL transmitter and to control the STL's peak modulation. This will optimize the signal-to-noise ratio of the entire transmission system.

    TROUBLESHOOTING ORBAN MODEL Whistle on Air, Perhaps Only in Stereo Reception The most likely cause is oscillation in the analog input or output circuitry. If the oscil- lation is in the output circuitry and is between 23 and 53 kHz, it will be detected in a receiver’s stereo decoder and translated down into the audible range.

  • Page 271: Shrill, Harsh Sound

    OPTIMOD-FM DIGITAL TROUBLESHOOTING Amplitude modulation of the carrier that is synchronous with the program (“syn- chronous AM”) can cause program-related crosstalk into subcarriers. Synchronous AM should be better than 35 dB below 100% modulation as measured on a syn- chronous AM detector with standard FM de-emphasis (50μs or 75μs). The subcarrier receiver itself must receive a multipath-free signal, and must have a wide and symmetrical IF passband and a linear, low-distortion FM demodulator to prevent program-related crosstalk into subcarriers.

    First, verify that a problem really exists by using a second frequency-measuring de- vice and/or verifying the problem with a monitoring service. If the problem is real, contact Orban Customer Service for a crystal replacement; there is no frequency trim available.
