    INTRODUCTION ORBAN MODEL 9300 The left/right digital input is on one XLR-type female connector on the rear panel; the mono digital output is on an XLR-type male connector on the rear panel. You can select whether OPTIMOD-AM uses its digital or analog input either locally or by remote interface.

    OPTIMOD-AM DIGITAL INTRODUCTION Computer Interface On the rear panel of the 9300 are an RS-232 serial port and a 100 Mbps Ethernet port for interfacing to IBM-compatible PCs either locally or through a TCP/IP net- work. These computer interfaces support remote control and metering, and allow downloading software upgrades.

    INTRODUCTION ORBAN MODEL 9300 2) The low-frequency 3 dB point of the system must be placed at 0.15Hz or lower (this is not a misprint!). This is necessary to ensure less than 1% overshoot in a 50Hz square wave and essentially constant group delay to 30Hz.

The best one can do is to use NRSC preemphasis, apply NRSC deemphasis before the lossy link’s input, and then re-apply NRSC preem- phasis at the link’s output. If only an analog link is available, use a 9300’s audio output and feed the audio di- rectly into the link.

  • Page 30: Digital Links

    1-10 INTRODUCTION ORBAN MODEL 9300 Digital Links Digital links may pass audio as straightforward PCM encoding or they may apply los- sy data reduction processing to the signal to reduce the number of bits per second required for transmission through the digital link. Such processing will almost in- variably distort peak levels;...

  • Page 31: Analog Microwave Stls

    Nevertheless, in an analog microwave system, the 9300 is usually located at the main AM transmitter and is driven by the microwave receiver. One of Orban’s studio level control systems (like our 6300) protects the microwave transmitter at the studio from overload.

  • Page 32: Analog Landline (Ptt/Post Office Line)

    1-12 INTRODUCTION ORBAN MODEL 9300 frees the system from potential overshoot. (The Orban 6300 can be configured to produce a pre-emphasized output.) Further, it is common for a microwave STL to bounce because of a large infrasonic peak in its frequency response caused by an under-damped automatic frequency control (AFC) phase-locked loop.

  • Page 33: Power Supplies

    1-13 OPTIMOD-AM DIGITAL INTRODUCTION The highly processed output of OPTIMOD-AM is carefully band-limited and peak- controlled. This output will often contain waveforms with flattops like square waves. If the transmitter has constant group delay above 30Hz, these difficult wave- forms will be transmitted intact and peak modulation will be accurately controlled. However, if low-frequency response is more than 3dB down at 0.15Hz, as would be true if a high-pass filter is present, the group delay above 30Hz will not be constant.

  • Page 34: Pre-1965 Transmitters

    1-14 INTRODUCTION ORBAN MODEL 9300 Sag is a result of inadequate steady-state regulation. It causes the conventional car- rier shift that is seen on a modulation monitor. Good transmitter engineering prac- tice usually limits this shift to -5% (which corresponds to about 0.5dB — not a highly significant loudness loss).

  • Page 35: Asymmetry

    1-15 OPTIMOD-AM DIGITAL INTRODUCTION Asymmetry While the physics of carrier pinch-off limit any AM modulation system to an absolute negative modulation limit of 100%, it is possible to modulate positive peaks as high as desired. In the United States, the FCC permits positive peaks of up to 125% modu- lation.
  • Page 36 1-16 INTRODUCTION ORBAN MODEL 9300 OPTIMOD-AM was designed with the assumption that one audio processor would be devoted to no more than two transmitters, usually called main and standby (or main and alternate). Each transmitter might be required to change power at night or to drive a different antenna array.

    1-20 INTRODUCTION ORBAN MODEL 9300 Transmission Levels The transmission engineer is primarily concerned with the peak level of a program to prevent overloading or overmodulation of the transmission system. This peak overload level is defined differently, system to system. In FM modulation, it is the maximum-permitted RF carrier frequency deviation. In AM modulation, it is negative carrier pinch-off.

The positive threshold is determined by the active transmission preset (see System Presets and Transmitter Equalization on page1-15), as are the set- tings of the highpass filter and transmitter equalizer.

    INTRODUCTION ORBAN MODEL 9300 Orban offers the optional model MRF-023 Monitor Rolloff Filter for this purpose. This filter is a small passive unit designed to be installed between the modulation monitor and the monitor amplifier. (See step 8 on page 2-5 for installation instruc- tions).

  • Page 43: Pc Control And Security Passcode

    This cutting of the bandwidth had the effect of reducing the receiver's high-frequency response, but it was felt that lower fidelity would be less obnoxious than interference. As long ago as 1978, Orban proposed and imple- mented preemphasis and low-pass filtering for AM broadcast to provide brighter sound at the receiver while minimizing interference.

  • Page 44: Nrsc Standard Preemphasis And Low-Pass Filtering

    1-24 INTRODUCTION ORBAN MODEL 9300 for conventional receivers (which implies a relatively extreme preemphasis), the newer receivers might sound strident or exceptionally bright. If the choice favored the newer receivers (less preemphasis and probably less processing), the majority of receivers would be deprived of much high-end energy and would sound both qui- eter and duller.

The purpose of the NRSC-2 RF mask is to provide a transmitted RF occupied bandwidth standard that any station with a properly operating transmitter will meet if NRSC-1 audio processing is used prior to the transmitter and if the station is not overmodu- lating.

    1. If your signal path includes a studio level controller, set it up. We recommend Orban’s 6300 Multipurpose Digital Audio Processor. The 6300 substitutes for the AGC in the 9300 at the transmitter and provides protection limiting for the STL. See Using OPTIMOD 6300 as a Studio Level Controller in the 6300’s operating manual.

  • Page 64 2-18 INSTALLATION ORBAN MODEL 9300 If you plan to modulate asymmetrically, you must leave headroom for the positive peaks. For example, you must set the DO 100% control lower than –2.0 dBfs to support 125% modulation. The most accurate way to set this control is by observing a modulation monitor or oscilloscope connected to your transmitter’s common point.

Later in this installation procedure, you will set 9300 for the highest modulation level that your facility can produce.

    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.

  • Page 190: Excessively Low Positive Peak Modulation

    TROUBLESHOOTING ORBAN MODEL 9300 Excessively Low Positive Peak Modulation The polarity of the 9300’s active output might be reversed. You can test this by edit- ing the P OLARITY field in the active System Preset. You may have not allowed enough peak headroom in the 9300’s output level set- ting.

  • Page 191: Audible Noise On Air

    STL may only be 70-75 dB. In this case, it is wise to use the Orban 6300 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.

  • Page 192: Dull Sound

    TROUBLESHOOTING ORBAN MODEL 9300 To reduce the audible effect of such ringing, minimize the amount of 5 or 6 kHz en- ergy applied to the filter. The most effective way to do this is to implement pre- emphasis with the HF parametric equalizer instead of the HF shelving equalizer. By boosting 3 kHz with the parametric equalizer, you will improve speech intelligibility on narrowband radios, yet the parametric’s bell-shaped boost curve will produce...
