    Adobe Acrobat Reader’s text search function. The 5518 FM Stereo Encoder Orban’s all-digital 5518 FM Stereo Encoder is a high-quality stand-alone stereo en- coder that operates at 64 kHz to 512 kHz sample rates and offers lowpass filtering, overshoot limiting, composite limiting, diversity delay, and an ITU412 multiplex power controller.

  • Page 22: Signal Processing Features

    The sample rate is 64 kHz and multiples thereof, up to 512 kHz. The inter- nal audio bandwidth is high enough to prevent overshoot caused by spectral truncation of the left/right input signals that are band-limited to 18 kHz or lower. This makes the 5518 compatible with all Orban OPTIMOD-FM audio proc- essors. ...

    5518-FM DIGITAL INTRODUCTION  A dual-mode composite limiter is available. The composite limiter uses a unique, “you can only do this in DSP” process that beats composite clippers by preserving stereo imaging while fully protecting the stereo pilot tone, RDS/RBDS, and subcarriers. It can operate in either “Half-Cosine Interpola- tion”...

    INTRODUCTION ORBAN MODEL 5518 The 5518 can apply J.17 deemphasis to signals applied to its digital input and J.17 preemphasis to the processed signal emitted from its digital output. J.17 is a 6 dB/octave shelving preemphasis/deemphasis standard with break points at 400 Hz and 4 kHz.

    5518-FM DIGITAL INTRODUCTION Subcarrier inputs sum into the composite baseband outputs. Rear-panel accessible PC-board-mounted trim pots allow the user to adjust the sensitivities of the two SCA inputs from <100 mV p-p to >10 V p-p to produce 10% injection with respect to 100% modulation = 4 V p-p at the 5518’s composite outputs (the factory setting is 4 V p-p to produce 10% injection).

    5518-FM DIGITAL INTRODUCTION configure the 5518 to lock its 19 kHz pilot tone and output sample frequency to this input. The sample frequency at the 5518’s digital output does not have to be the same as the reference frequency. If the output frequency is different, the output sample fre- quency will be the product of a quotient of integers times the reference frequency.

    1-10 INTRODUCTION ORBAN MODEL 5518 3) Any preemphasis used in the audio transmission system prior to the stereo en- coder must be canceled by a precisely complementary deemphasis: Every pole and zero in the preemphasis filter must be complemented by a zero and pole of identical complex frequency in the deemphasis network.

This is available from: ftp.orban.com/CIT25/CIT25 Instructions.pdf (Please note that Orban no longer manufactures the CIT25, which used the Jensen transformer.) If you need to drive an auxiliary or standby transmitter, the best way to connect it to the 5518 is via the 5518’s second composite output.

    1-12 INTRODUCTION ORBAN MODEL 5518 verely. This will force you use the 5518’s left/right overshoot limiters to apply heavy limiting, which can reduce audio quality. For any lossy compression system the higher the data rate, the less the peak levels will be corrupted by added noise, so use the highest data rate practical in your system.

  • Page 33: Dual Microwave Stls

    1-13 5518-FM DIGITAL INTRODUCTION In general, a composite microwave STL provides good audio quality, as long as there is a line-of-sight transmission path from studio to transmitter of less than 10 miles (16 km). If not, RF signal-to-noise ratio, multipath distortion, and diffraction effects can cause serious quality problems.

  • Page 34: About Transmission Levels And Metering

    1-14 INTRODUCTION ORBAN MODEL 5518 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 35: Transmission Levels

    1-15 5518-FM 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 sat- ellite links), it is the maximum-permitted RF carrier frequency deviation.

    1-16 INTRODUCTION ORBAN MODEL 5518 put, the maximum digital word at the input corresponds to the 0 dB point on the 5518’s input meter. Composite Output Level When its left/right overshoot limiter and composite limiter are enabled, the 5518 controls instantaneous, absolute peak levels to a tolerance of approximately 0.1 dB.

  • Page 49: Quick Setup

    When the 5518’s stereo encoder is driving an unbalanced exciter input, you may encounter a ground loop. (Some older exciters have unbalanced inputs.) Unlike some older Orban FM processors, the 5518 does not have a ground lift switch. If you cannot reconfigure your grounding scheme to eliminate such a loop, you can balance and float the exciter input with a Jensen JT-123-BLCF transformer (see page 2-10).

  • Page 57 When operating in Half-Cosine mode, the composite limiter produces somewhat less brightness but does not compromise stereo imaging. Be- cause this mode produces lower subjective distortion, Orban’s factory programmers prefer the sound of the Half-Cosine mode. In either mode, the baseband output is overshoot compensated and bandlimited to 53 kHz, unlike conventional composite clippers.
  • Page 58 2-20 INSTALLATION ORBAN MODEL 5518 We recommend setting the control to “0.” This sets the limiter threshold to be the same as the analog and digital reference levels, which corre- spond to 100% baseband tone modulation. This setting only removes overshoots.

The 5518 can store an indefinite number of user presets, limited only by available memory.

    OPERATION ORBAN MODEL 5518 SSB Stereo Encoder Operation Starting with version 1.2.1, the 5518 allows its stereo encoder’s stereo subchannel modulator to operate in an experimental compatible single sideband/vestigial side- band mode. Please note that to control modulation peaks successfully in SSB/VSB mode, you must activate the 5518’s composite limiter.

  • Page 131: Test Modes

    5518-FM DIGITAL OPERATION The group delay of the phase-linear filters needed to create the SSB/VSB waveform and the audio delay in the look-ahead limiter together add approximately 12 ms to the delay of the stereo encoder. When diversity delay is applied to the 5518’s com- posite output, the 5518 adjusts the delay automatically so that it is constant regard- less of mode.

    5518-FM DIGITAL TECHNICAL DATA User Control Interface and LCD Display Circuits The user control interface enables the user to control the 5518’s functionality. A rear panel GPI connector allows optically isolated remote control of certain functions, such as recalling presets, via contact closure. An RS-232 serial port and an Ethernet port allow you to connect a modem or computer to the 5518.

    TECHNICAL DATA ORBAN MODEL 5518 3. LED Meter Circuits Located on display board The meter LEDs are arranged in an 8x16 matrix, in rows and columns. Each row of LEDs in the matrix has a 1/8 duty cycle ON time. The rows are multi- plexed at a fast rate so that the meters appear continuously illuminated.

These com- ponents apply a 3 order lowpass filter to the differential signal from the D/A. This filter does not induce significant overshoot of the processed audio, which would otherwise waste modulation.

    During system initialization, the SC520 queries the DSP hardware about its opera- tional status and will display an error message on-screen if the DSP fails to initialize normally. Please note any such messages and be ready to report them to Orban Cus- tomer Service.

    Because of safety and EMI suppression requirements in the power supply, there are no user-serviceable parts in it. In case of failure, replace the entire supply with an Orban-supplied replacement (Orban part number 29270.000.01.1), which ensures that your 5518 will continue to meet all regulatory requirements for safety and emissions.
