OPTIMOD 6300 DIGITAL INTRODUCTION Section 1 Introduction Crucial Information for Video Applications— Please Read! To make automatic loudness control as straightforward and dependable as possible, the 6300 operates somewhat differently from other Optimods.  Dialnorm: The 6300 works very easily with Dolby Digital® transmission systems if you do one crucial thing: You must tell the 6300 what value of Dolby Digital Dialnorm metadata you are transmitting to your audience.
Page 26 INTRODUCTION ORBAN MODEL 6300 value of D that the Dolby Digital encoder is transmitting to your IALNORM audience.  Setting Output Loudness: To set the 6300’s output loudness, adjust its value or adjust the MB L IALNORM IMITER RIVE control in the active Processing Preset.

INTRODUCTION ORBAN MODEL 6300  OPTIMOD 6300 controls the audio bandwidth as necessary to accommodate the transmitted sample frequency. OPTIMOD 6300’s high frequency bandwidth can be switched instantly (typically in 1 kHz increments) between 10 kHz and 20 kHz. 20 kHz is used for highest-quality systems. 15 kHz meets the requirements of any system that uses 32 kHz sample frequency, while 10 kHz is appropriate for 24 kHz sample frequency.
Page 31: Controllable
INTRODUCTION  A special 2-band preset creates a no-compromise “Protect” function that is func- tionally similar to the “Protect” structures in earlier Orban digital processors. The 5-band and the 2-band structures can be switched via a mute-free crossfade.  The 6300 includes third-generation CBS Loudness Controllers™ for DTV appli- cations.
Page 32: Presets In Optimod 6300
(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 34: 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.

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 36: Where Access To The Transmitter Is Not Possible
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...
Page 37: Using Optimod 6300 As A Studio Level Controller
Using OPTIMOD 6300 as a Studio Level Controller See page 6-43 for a block diagram of the 6300’s signal processing and routing. Because of its versatile signal routing, OPTIMOD 6300 can be used as a combined studio AGC, digital radio/netcast processor, and low-delay talent headphone proces- sor.
Page 38 ORBAN MODEL 6300 The 6300’s AGC uses the same dual-band, window-gated, matrix technol- ogy as the AGCs in Orban’s 2300, 5300, 8300, 8382, 8400, 8500, 9300, and 9400 Optimods. It can therefore accurately substitute for the AGCs in these devices and can help maintain an all-digital signal path throughout the facility.
Page 39: Studio-Transmitter Link
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...
Page 40 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...
Page 41: Microwave Stls
Nevertheless, in a system using a microwave STL OPTIMOD 6300 is sometimes located at the studio and any overshoots induced by the link are tolerated or removed by the transmitter’s protection limiter (if any).
Page 42: Using Lossy Data Reduction In The Audio Chain Before The 6300
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 43: Aes User Bits
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, these filters will pass the band-...
Page 44: About Transmission Levels And Metering
1-20 INTRODUCTION ORBAN MODEL 6300 About Transmission Levels and Metering Meters Studio engineers and transmission engineers consider audio levels and their meas- urements differently, so they typically use different methods of metering to monitor these levels. The VU meter is an average-responding meter (measuring the approxi- mate RMS level) with a 300ms rise time and decay time;...
Page 45: Transmission Levels
1-21 OPTIMOD 6300 DIGITAL INTRODUCTION In facilities that use the BBC-standard PPM, maximum program level is usually PPM4 for music, PPM6 for speech. Line-up level is usually PPM4, which corresponds to +4dBu. Instantaneous peaks will reach +17dBu or more on voice.
Page 46 1-22 INTRODUCTION ORBAN MODEL 6300 subjective loudness.  Input levels are displayed using a VU-type scale 0 to –40dB), but the metering indicates absolute instantaneous peak (much faster than a standard PPM or VU meter). The maximum digital word at the input corresponds to the 0 dB point on the 6300’s input meter.
Page 47 TV viewers but that the BS.1770-2 meter, because of its longer integration time, may not take fully into ac- count. Created using Orban-developed modeling software, the DSP im- plementation typically matches the original CBS analog meter within 0.5 dB on sinewaves, tone bursts and noise.
Page 48 1-24 INTRODUCTION ORBAN MODEL 6300 mally heard. They published this work along with results from other tests whose goal was to model the loudness integration time constants of human hearing. These studies concentrated on the moderate sound lev- els typically preferred by people listening to broadcasts (60 to 80 phons and did not attempt to characterize loudness perception at very low and high levels.
Page 49: Test Modes
Test Tone. 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 50: Monitoring On Loudspeakers And Headphones
Monitoring on Loudspeakers and Headphones In live operations, highly processed audio often causes a problem with the DJ or presenter’s headphones. The delay through OPTIMOD 6300 can be as much as 25ms (or more, if the installer purposely adds frame-makeup delay). This delay, al- though not usually audible as a distinct echo, can cause bone conduction comb fil- tering of the DJ/presenter’s voice in his/her ears.
Page 51: Streaming And Netcasting Applications
See Processing for Low Bit Rate Codecs on page 3-5. Loudness You can expect a significant increase in loudness from OPTIMOD 6300 processing by comparison to most unprocessed audio. An exception is recently mastered CDs, which may have already been ag- gressively processed for loudness when they were mastered.
Page 52: Eas Test
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.

INSTALLATION ORBAN MODEL 6300 To permit daisy-chaining sync signals, the input impedance is greater than 1 K. If the 6300 is the last device driven by the sync coaxial cable, you should terminate it by using a BNC Tee connector and a 75 BNC terminator. This will prevent perform- ance-degrading reflections in the cable.

Page 86 2-32 INSTALLATION ORBAN MODEL 6300 When set to In, the 6300 adds “high-pass” dither before any truncation of the output word. The amount of dither automatically tracks the set- ting of the W control. This first-order noise shaped dither consid- erably reduces added noise in the midrange by comparison to white PDF dither.

Page 147: Loudness And Distortion
In processing, there is a direct trade-off between loudness and distortion. You can improve one only at the expense of one or both of the other two. Thanks to Orban’s psychoacoustically optimized designs, this is less true of Orban processors than of any others.

Page 179 3-37 OPTIMOD 6300 DIGITAL OPERATION MID WIDTH determines the bandwidth of the equalization, in octaves. The range is 0.8-4.0 octaves. If you are unfamiliar with using a parametric equalizer, 1 octave is a good starting point.

AGC DRIVE control adjusts signal level going into the slow dual-band AGC, there- fore determining the amount of gain reduction in the AGC.
Page 184 AGC GATE (“AGC Gate Threshold”) control determines the lowest input level that will be recognized as program by OPTIMOD 6300; lower levels are considered to be noise or background sounds and cause the AGC or multiband compressor to gate, effectively freezing gain to prevent noise breathing.
Page 185: Advanced Agc Controls
3-43 OPTIMOD 6300 DIGITAL OPERATION AGC B CPL (“AGC Bass Coupling”) control clamps the amount of dynamic bass boost (in units of dB) that the AGC can provide. (In V1.0, the unit of measure was percent.) The AGC processes audio in a master band for all audio above approximately 200 Hz and a bass band for audio below approximately 200 Hz.
Page 186 3-44 OPERATION ORBAN MODEL 6300 AGC Ratio determines the compression ratio of the AGC. The compression ratio is the ratio between the change in input level and the resulting change in output level, both measured in units of dB. The 6300 compressor can be operated at a compression ratio as low as 2:1. This can add a sense of dynamic range and is mostly useful for subtle fine arts formats like classical and jazz.
Page 187 3-45 OPTIMOD 6300 DIGITAL OPERATION This control works the same regardless of whether the AGC operates in left/right or sum / difference M modes, in both cases controlling the ATRIX maximum gain difference between the “channels.” Depending on the Matrix mode setting, the “channels” will handle left and right signals or will handle sum and difference signals.

3-48 OPERATION ORBAN MODEL 6300 The 2-band structure has an open, easy-to-listen-to sound that is similar to the source material if the source material is of good quality. We recommend using it when you want to preserve the spectral balance of the source material while not significantly increasing program density.
Page 191 3-49 OPTIMOD 6300 DIGITAL OPERATION 2B REL (“2B Release”) control determines how fast the 2-band compressor releases (and therefore how quickly loudness increases) when the level of the program mate- rial decreases. This release time only applies when the silence gate does not gate the 2-band Compressor.
Page 192 2B GATE (“2B Gate Threshold”) threshold control determines the lowest input level that will be recognized as program material by OPTIMOD 6300; lower levels are con- sidered to be noise or background sounds and will cause the AGC or 2-band com- pressor to gate, effectively freezing gain to prevent noise breathing.

3-52 OPERATION ORBAN MODEL 6300 prefer the more open sound of the 5-band compressor without additional loudness control. The loudness controller sidechain receives the output of the MB Limiter. Hence, the loudness controller responds accurately to all 6300 audio processing except look- ahead limiting, which is a peak limiting process whose gain reduction does not sig- nificantly affect subject loudness.
Page 195 3-53 OPTIMOD 6300 DIGITAL OPERATION BS.1770 Limiter Threshold sets the threshold of the BS.1770 safety limiter (in units of LK or LU) with respect to the active D IALNORM value. See BS.1770 Safety Limiter on page 3-13. 2B Master Compression Threshold sets the level where gain reduction starts to occur in the Master (above 200Hz) band of the 2-band Compressor.

Page 202 3-60 OPERATION ORBAN MODEL 6300 Note also that it is virtually impossible to achieve undetectable dynamic noise reduc- tion of program material that is extremely noisy to begin with, because the program never masks the noise. It is probably wiser to defeat the dynamic noise reduction with this sort of material (traffic reports from helicopters and the like) to avoid ob- jectionable side effects.

3-61 OPTIMOD 6300 DIGITAL OPERATION (6.2 kHz and above) is determined by and follows the gain of band 4. The sum of the high frequency limiter control signal and the output of the B4>B5 determines the gain reduction in band 5.
