  • Page 23: Section 1 Introduction

    Because OPTIMOD-TV incorporates several audio processing innovations ex- clusive 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 24: User-Friendly Interface

    If you wish to place level protection prior to your studio / transmitter link (STL), use an Orban studio level control system expressly designed for this purpose. (At the time of this writing, this is the Orban 8200ST OPTIMOD-Studio Compressor/limiter / HF Limiter / Clipper.) The 8200ST can be adjusted so that it substitutes for the broad-...

  • Page 25: Flexible Configuration

    Flexible Configuration  The 8382 includes analog and AES3 digital inputs and outputs. Both digital in- put and digital output are equipped with sample-rate converters and can oper- ate at 32 kHz, 44.1 kHz, 48, 88.2, and 96 kHz sample rates. The pre-emphasis status and output levels are separately adjustable for the analog and digital outputs.

    Windows Dial-Up or Direct Cable Connection if appropriate. The PC Remote software allows the user to access all 8382 features (including advanced controls not available from the 8382’s front panel), and allows the user to archive and re- store presets, automation lists, and system setups (containing I/O levels, digital word lengths, GPI functional assignments, etc.).

  • Page 27: Presets In Optimod-Tv

    You can store more than 100 User Presets, limited only by available memory in your 8382 (which will vary depending on the version of your 8382’s software). You can give your preset a name up to 18 characters long.

  • Page 28: Digital Aes3 Left/Right Input/Output

    Dual-mono or stereo mode is a global system parameter. You can change modes manually, via the 8382’s GPI inputs, via 8382 PC Remote software, or via the 8382’s built-in time-of-day automation. Further, the 8382 can be programmed to recognize the “stereo”...

  • Page 29: Analog Left/Right Input/Output

    In this case, the principal program modulation level must be reduced when a subcarrier is turned on. The 8382’s remote control feature allows you to reduce the 8382’s output level (thus reducing the principal program modulation level) by connecting an on/off signal from your subcarrier generator.

  • Page 30: Computer Interface

    ORBAN MODEL 8382 Computer Interface On the rear panel of the 8382 are an RS-232 serial port and an Ethernet port for in- terfacing to IBM-compatible PCs. These computer interfaces support remote control and metering, and allow downloading software upgrades.

    30-15,000Hz, and low non-linear distortion. If you use a stereo encoder, feed the encoder directly from the 8382’s left and right analog outputs. If possible, bypass the pre-emphasis network and the input low-pass filters in the encoder so that they cannot introduce spurious peaks.

    8382 to the transmit- ter. For example, the MPEG Layer 2 algorithm can increase peak levels up to 4 dB at 160 kB/sec by adding large amounts of quantization noise to the signal.

  • Page 34: Composite Baseband Microwave Stls

    The installing engineer should be aware of all of these potential problems when designing a transmission system. Any problems can be minimized by always driving a digital STL with the 8382’s AES3 digital output, which will provide the most accurate interface to the STL. The digital input and output accommodate sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz,...

  • Page 35: Dual Microwave Stls

    Nevertheless, in a system using a microwave STL, the 8382 is sometimes located at the studio and any over- shoots induced by the link are tolerated or removed by the transmitter’s protection limiter (if any).

  • Page 36: Video Microwave Stls With Audio Subcarriers

    8382’s remote control feature offers the means to reduce the peak level of the 8382’s audio output as necessary. This way, you can still use the 8382’s line-up tone to adjust the steady-state deviation to 75 kHz. Yet, the reduced peak level of the audio emitted from the 8382 ensures that the carrier deviates no further than 75...

  • Page 37: Using Lossy Data Reduction In The Studio

    1-15 OPTIMOD-TV DIGITAL INTRODUCTION Using Lossy Data Reduction in the Studio Many broadcasters are now using lossy data reduction algorithms like MPEG-1 Layer 2 or Dolby AC2 to increase the storage time of digital playback media. In addition, source material is often supplied through a lossy data reduction algorithm, whether from satellite or over landlines.

    EAS tones and data can be accomplished in three different ways: 1. Run EAS tones and data through the 8382. Note that 8382 processing may not allow the full modulation level as required by EAS standards. It may therefore be necessary to temporarily defeat the 8382’s processing during the broadcast of EAS tones and data.

    BNC connectors. Power Ground  Ground the 8382 chassis through the third wire in the power cord. Proper grounding techniques never leave equipment chassis unconnected to power / earth ground. A proper power ground is essential for safe operation. Lifting a chassis from power ground creates a potential safety hazard.

  • Page 51: 8382 Front Panel

    In high RF fields, the system is usually grounded through the equipment rack in which the 8382 is mounted. The rack should be connected to a solid earth ground by a wide copper strap—wire is completely ineffective at VHF because of the wire’s self-inductance.

    In most cases, we recommend that you leave the phase rotator active to minimize speech distortion. However, because it can slightly reduce the clarity and definition of program material, you can defeat it if you are operating the 8382 conservatively. Stereo Enhancer Controls The stereo enhancer emulates the Orban 222 analog stereo enhancer.

The AGC is also ordinarily defeated if you are using a studio level controller (like Orban’s 8200ST). However, in this case it is better to defeat the AGC globally in System Setup.
  • Page 133 In television audio, the setting of the gate threshold controls are quite critical if you want the processing to be undetectable to the audience. If this control is set too low, then the 8382 will pump up quiet sounds such as ambience and underscoring to unnaturally high levels.
  • Page 134 3-26 OPERATION ORBAN MODEL 8382 The multiband silence gate causes the gain reduction in bands 2 and 3 of the multi- band compressor to move quickly to the average gain reduction occurring in those bands when the gate first turns on. This prevents obvious midrange coloration un- der gated conditions, because bands 2 and 3 have the same gain.

    Bass Clip (“Bass Clip Threshold”) sets the threshold of Orban’s patented embedded bass clipper with reference to the final clipper. In the realization found in the 8382, this clipper uses special techniques to reduce distortion. The bass clipper is embed- ded in the multiband crossover so that any remaining distortion created by clipping is rolled off by part of the crossover filters.
  • Page 137 Some 8382 users feel that the bass clipper unnecessarily reduces bass punch at its factory settings. Therefore, we made the threshold of the bass clipper user- adjustable. The range (with reference to the final clipper threshold) is 0 to –6dB. As you raise the threshold of the clipper, you will get more bass but also more distor- tion and pumping.

Large changes in the frequency bal- ance of the compressor outputs will change this tuning, leaving the 8382 more vul- nerable to unexpected audible distortion with certain program material. Therefore, you should make large changes in EQ with the bass and parametric equalizers and the HF enhancer, because these are located before the compressors.

  • Page 188 5-14 TROUBLESHOOTING ORBAN MODEL 8382 packing sheets, thick fiber blankets, and the like are acceptable cushioning materi- als; foam “popcorn” and crumpled newspaper are not. Wrap cushioning materials tightly around the unit and tape them in place to prevent the unit from shifting out of its packing.

    Polarity (Two-Band and Bypass Modes): Absolute polarity maintained. Positive-going signal on input will result in positive-going signal on output. Processing Sample Rate: The 8382 is a “multirate” system, using internal rates from 32 kHz to 256 kHz as appropriate for the processing being performed. Audio clippers oper- ate at 256 kHz.
  • Page 190 3 electronically balanced, floating and symmetrical. A/D Conversion: 24 bit 128x oversampled delta sigma converter with linear-phase anti- aliasing filter. Converter outputs 64 kHz sample rate, which the 8382 then decimates to 32 kHz in DSP using an ultra-high-quality image-free synchronous sample rate con- verter.
  • Page 191 OPTIMOD-TV DIGITAL TECHNICAL DATA Input Reference Level: Variable within the range of –30 dBFS to –10 dBFS. J.17 De-emphasis: Software-selectable. Filtering: RFI filtered. Digital Audio Output Configuration: Stereo or Two-Channel per AES3 standard. Output configured in software as flat or pre-emphasized to the chosen processing pre-emphasis (50µs or 75µs), with or without J.17 pre-emphasis.

    RFI / EMI: Tested according to Cenelec procedures. FCC Part 15 Class A device. Shipping Weight: 19 lbs / 8.7 kg Warranty Two Years, Parts and Service: Subject to the limitations set forth in Orban's Standard Warranty Agreement. Because engineering improvements are ongoing, specifications are subject to change with- out notice.
  • Page 193 DSP code download has finished. If you hear a short audio mute on air, this may be because the 8382 has rebooted for some reason. (Of course, it could also be caused by the 8382’s audio feed’s being interrupted.) Be prepared to convey this fact to Orban customer service if you call for technical assistance.
  • Page 194 Current must flow consistently for 50msec for the signal to be inter- preted as valid. Generally, the 8382 will respond to the most recent control op- eration, regardless of whether it came from the front panel, remote interface, or RS-232.
  • Page 195 OPTIMOD-TV DIGITAL TECHNICAL DATA sends the appropriate LED control words (eight bits at a time) to the data latches that drive the LEDs directly. Component-Level Description: The meter LED matrix consists of ten 10-segment LED bar graph assemblies (CR1-CR9, CR16) and one discrete LED (CR10). Row selector latches IC4, IC5, IC6, and IC9 are controlled by the host microprocessor and alternately sink cur- rent through the LEDs selected by column selector latches IC1 and IC2, which are also controlled by the SC520.

    The A/D oversamples the audio, applies noise shaping, and filters and decimates to 64 kHz sample rate. (An Orban-designed synchronous sample rate converter in the 8382’s DSP performs the final decimation to 32 kHz. This ensures the flattest frequency response to 15 kHz without aliasing.) 3.
  • Page 197 OPTIMOD-TV DIGITAL TECHNICAL DATA 1. Stereo Digital-to-Analog (D/A) Converter Located on input/output board The D/A, IC211, is a stereo, 24-bit delta-sigma converter. It receives the serial left and right audio data samples from the DSP at 64 kHz sample rate, and converts them into audio signals requiring further, relatively undemanding analog filter- ing.

  • Page 198: Power Supply

    An integrated output sample rate converter (SRC) and AES3 line driver chip, IC502, converts the 32 kHz 8382 system sample rate to any of the standard 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz rates, and also contains a digital au- dio interface transmitter to encode digital audio signals using the AES3 interface format (AES3-1992).
  • Page 199 The output of the power supply is monitored by the power-indicator LED circuit, which causes the power LED to flash according to a preset code to diagnose prob- lems with the various power supplies in the 8382. See step (2.B) on page 4-8. Abbreviations...
