    INTRODUCTION ORBAN MODEL 6300 The rest of Chapter 1 explains how OPTIMOD 6300 fits into the DAB and DTV broad- cast plants and how to use it for netcasting. Chapter 2 explains how to install it. Chapter 3 explains how to operate OPTIMOD 6300. Chapters 4 through 6 provide reference information.

    (by connecting a Windows® computer to the 6300’s serial port through the sup- plied null modem cable). Presets in OPTIMOD 6300 There are two distinct kinds of presets in OPTIMOD 6300: factory presets and user presets. Factory Presets The Factory Presets are our “factory recommended settings” for various program formats or types.

    Digital AES3 left/right inputs and dual outputs.  Analog left/right inputs and outputs. OPTIMOD 6300 can be operated in either stereo or dual-mono mode. In dual-mono mode, processing parameters that determine the “sound” of the processor are the same on both channels.

  • Page 29: Analog Left/Right Input/Output

    You select whether OPTIMOD 6300 uses the digital or analog input either locally or by remote interface. If OPTIMOD 6300 is set to accept a digital input and the feed fails, OPTIMOD 6300 will automatically switch back to the analog input.

  • Page 31: Location Of Optimod 6300

    6300 is to be used as a studio AGC. At the transmitter is best The best location for OPTIMOD 6300 is as close as possible to the transmitter or en- coder so that OPTIMOD 6300’s AES3 output can be connected to the transmitter or encoder through a circuit path that introduces no change in OPTIMOD 6300’s output...

  • Page 32: Optimod 6300 At The Transmitter: Gain Control Before The Stl

    To achieve the full audible benefit of OPTIMOD 6300 processing, use a studio- transmitter link (STL) that is as flat as the bandwidth of OPTIMOD 6300 as used in your plant (usually 20 kHz). Ideally, you should use a 20-bit (or better) uncompressed digital link with at least 44.1 kHz sample frequency.
  • Page 33 INTRODUCTION  OPTIMOD 6300 substitutes for the AGC in an Optimod at the transmitter and provides protection limiting for the STL. Digital output #1 emits the peak-limited output of the AGC to drive the STL. The AGC is turned off in the transmitter-side Optimod.

  • Page 34: Studio-Transmitter Link

    STLs are used in two fundamentally different ways. Either they can pass unprocessed audio for application to OPTIMOD 6300’s input or they can pass OPTIMOD 6300’s peak-controlled output. The two applications have fundamentally different per- formance requirements.

  • Page 35: Digital Links

    It is practical (though not ideal) to use lossy data reduction to pass unprocessed au- dio to OPTIMOD 6300’s input. The data rate should be at least of “contribution qual- ity”—the higher, the better. If any part of the studio chain is analog, we recommend using at least 20-bit A/D conversion before encoding.

  • Page 36: Microwave Stls

    The installing engineer should be aware of all of these potential problems when designing a transmission system. You can minimize any problems by always driving a digital STL with OPTIMOD 6300’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, 88.2,...

  • Page 37: Analog Landline (Ptt/Post Office Line)

    Sometimes, several encode/decode cycles will be cascaded before the material is finally presented to OPTIMOD 6300’s input. All such algorithms operate by increasing the quantization noise in discrete fre- quency bands.

  • Page 38: Interfacing To The Transmitter

    Mondiale (DRM) system also allows reduced audio bandwidths and sample rate for speech-grade services. OPTIMOD 6300’s bandwidth can be adjusted from 10 kHz to 20 kHz to provide cor- rectly anti-aliased audio for any of these systems. As long as any anti-aliasing filters following OPTIMOD 6300’s output are phase-linear and have integer sample time...

  • Page 39: Subframe Delay

    It is therefore less likely that peaks will “slip between the samples.” Subframe Delay OPTIMOD 6300 provides an adjustable time delay of up to 96 milliseconds. This al- lows the installer to force the total delay through the processing to equal one frame (in sound-for-picture applications).

  • Page 40: Studio Line-Up Levels And Headroom

    1-18 INTRODUCTION ORBAN MODEL 6300 ABSOLUTE PEAK Figure 1-1: Absolute Peak Level, VU and PPM Reading Studio Line-up Levels and Headroom 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 41: Transmission Levels

    1-19 OPTIMOD 6300 DIGITAL INTRODUCTION Transmission Levels The transmission engineer is primarily concerned with the peak level of a program to prevent overloading or over-modulation of the transmission system. This peak overload level is defined differently, system to system. In FM modulation (FM / VHF radio and television broadcast, microwave or analog satellite links), it is the maximum-permitted RF carrier frequency deviation.

  • Page 42: Built-In Calibrated Bypass Test Mode

    Setting Output/Modulation Levels In a perfect world, one could set the peak level at OPTIMOD 6300’s output to 0 dBfs. However, there are at several potential problems that may make it desirable to set the modulation level slightly lower.

  • Page 43: Monitoring On Loudspeakers And Headphones

    In the latter case, you will route the encoded audio to the netcast server application through your network. See Processing for Low Bit Rate Codecs on page 3-4. Loudness You can expect a significant increase in loudness from OPTIMOD 6300 processing by comparison to most unprocessed audio.

  • Page 44: Choosing Your Encoder

    Thanks to the Apple iPod®, AAC/MP4/M4A is rap- idly becoming the defacto standard for downloadable music. OPTIMOD 6300 is well matched to AAC/aacPlus and to MP3. It can effectively pre- process audio intended for playback from either format. If you decide to use MP3, choose your MP3 encoder wisely, as not all MP3 encoders are created equal and pro- vide different levels of quality for a given bitrate.

  • Page 45: Pc Control And Security Passcode

    PC Control and Security Passcode PC software control provides access to OPTIMOD 6300 via network, modem or direct (null modem cable) connection, with IBM PC-compatible computers running Win- dows 2000 or XP. PC access is permitted only with a valid user-defined passcode.

There is a tradeoff between this control and the amount of gain reduction in the look-ahead limiter, which will have to eliminate attack transients exceeding the look-ahead limiter’s threshold.
  • Page 188 3-70 OPERATION ORBAN MODEL 6300 At 44.1 kHz, the output samples are not exactly the same ones that the look-ahead limiter controlled at the internal 48 kHz sample rate, so slight overshoot can occur.

    TROUBLESHOOTING ORBAN MODEL 6300 Verify that the source material at the 6300's audio inputs is clean. Heavy processing can exaggerate even slightly distorted material, pushing it over the edge into unac- ceptability. The subjective adjustments available to the user have enough range to cause audi- ble distortion at their extreme settings.

    STL may only be 70-75 dB. In this case, it is wise to use an Orban Studio AGC to perform the AGC function 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.
