Overview

Optimod FM/ HD 5700i (DISCONTINUED)

For years, broadcasters have trusted Optimod-FM 8500 to build audiences and ratings with its big, bold sound. Optimod-FM 5700i now offers the popular 8500 sound in a compact, cool-running 1U package at a more affordable price. The 5700i provides stereo enhancement, equalization, AGC, multiband compression, low-IM peak limiting, stereo encoding, and composite limiting—everything that you need to compete in your market.More than 20 excellent sounding, format-specific factory presets get you started. You'll find all of your favorite 8500 presets here. Although the factory presets are fully competent “out of the box,” you can customize them with easy one-knob LESS-MORE control or with more than 60 advanced controls whose versatility will satisfy even the most finicky on-air sound designer. If you have created custom presets for Optimod-FM 8500, 8400, 8300, 5500, or 5300, you'll find that they import perfectly into the 5700i, retaining your carefully designed sound.

Independent Processing

The FM and digital media processing paths split after the 5700i's stereo enhancer and AGC. There are two equalizers, multiband compressors, and peak limiters, allowing the analog FM and digital media processing to be optimized separately. The bottom line? Processing that optimizes the sound of your FM channel while punching remarkably crisp, clean, CD-like audio through to your digital channel audience.

Versatility Doesn't Stop With Sound

If you choose to use the 5700i's superb DSP-based stereo encoder and composite limiter, be assured that they deliver an FM analog signal that is always immaculately clean and perfectly peak limited, with full spectral protection of subcarriers and RDS/RBDS regardless of the amount of composite limiting.The 5700i includes a “ratings encoder loop-through” connection. This allows a ratings encoder with an AES3 digital input and output to be inserted between the output of the AGC, before the analog-FM and HD processing paths split or between the output of the audio processing and the input to the stereo encoder. This keeps the audio level driving the ratings encoder as high as possible, minimizing the number of “low audio level” alarms that the ratings encoder generates.For our European customers, a second-generation ITU BS 412 multiplex power controller smoothly and naturally complies with the standard.

RDS

The 5700i includes a full-featured RBS/RBDS generator at no additional charge. The generator supports dynamic PS. It can be controlled via the 5700i presets and an ASCII terminal server that can be connected to automation to support displaying title and artist.

Controllable

The front-panel display includes a 2x40-character LCD and LED bargraphs that show all metering functions of the processing structure (Two-Band or Five-Band) in use. The metering is always visible while you are adjusting the processor. Navigation is by dedicated buttons, soft buttons (whose functions are context-sensitive), and a large rotary knob.Ethernet connectivity is standard, as is an easy to use PC remote control application that runs on Windows XP and higher and that can control many 5700i units on a TCP/IP network. Additionally, programmable contact-closure (GPI) control plus ACSII terminal control via the 5700i's RS232 serial and Ethernet ports together give you total freedom to interface the 5700i with your facility's remote control infrastructure, whatever it might be. SNMP support offers yet another way to control and monitor the 5700i's operation via your network.

Administrating and Monitoring

The SNMP (Simple Network Management Protocol) features allow you to monitor your Optimod’s status and to send Alarm notifications via your Optimod’s Ethernet connection to your network.API: This interface can be used to allow custom third-party applications (including automation systems) to recall presets, view status and set the controls.

Upgradeable

To protect your investment, the 5700i can be upgraded to full 8600Si functionality via a purchased upgrade kit. There's no need to remove the unit from the rack, and you will immediately benefit from Orban's state-of-the-art MX limiter technology.

 

Specifications

Frequency Response (Bypass Mode): Follows standard 50μs or 75μs pre-emphasis curve ±0.10 dB, 2.0 Hz–15 kHz. Analog left/right output and digital output can be user- configured for flat or pre-emphasized output.

Noise: Output noise floor will depend upon how much gain the processor is set for (Limit Drive, AGC Drive, Two-Band Drive, and/or Multi-Band Drive), gating level, equalization, noise reduction, etc. The dynamic range of the A/D Converter, which has a specified overload-to–noise ratio of 110 dB, primarily governs it. The dynamic range of the digital signal processing is 144 dB.

Total System Distortion (de-emphasized, 100% modulation): <0.01% THD, 20 Hz–1 kHz, rising to <0.05% at 15 kHz. <0.02% SMPTE IM Distortion.

Total System L/R Channel Separation: >50 dB, 20 Hz – 15 kHz; 60 dB typical. 
Polarity (Two-Band and Bypass Modes): Absolute polarity maintained. Positive-going signal on input will result in positive-going signal on output when HD Polarity and FM polarity controls are set to POSITIVE.

Processing Sample Rate: The 5700i is a “multirate” system, using internal rates from 64 kHz to 512 kHz as appropriate for the processing being performed. Audio clippers oper- ate at 256 kHz (and are anti-aliased), while the composite limiter operates at 512 kHz.

Peak Control at HD Output: The true peak limiter is oversampled at 256 kHz, yielding a worst- case overshoot of 0.5 dB at the analog output and for all output sample rates. (To achieve this performance at 32 kHz output sample rate, it is necessary to set the 5700i’s HD lowpass filter cutoff frequency to 15 kHz.)

Processing Resolution: Internal processing has 24 bit (fixed point) or higher resolution. 
 

Delay

Defeatable Analog FM Processing delay: 0.27 to 16.384 seconds, adjustable in one- sample increments at 64 kHz sample rate to allow the delays of the analog and digital paths in the HD Radio system to be matched at the receiver output. 

Minimum Processing Delay: Processing structure dependent. Typically 17 ms for normal latency Five-band, 13 ms for low-latency Five-band, 3.7 ms for ultra-low-latency Five- band, and 17 or 22 ms for 2-band, depending on crossover structure chosen.

Sampling Rate: 32, 44.1, 48, 88.2, or 96 kHz, automatically selected.

Connector: XLR-type, female, EMI-suppressed. Pin 1 chassis ground, pins 2 and 3 transformer balanced and floating, 110Ω impedance.

Input Reference Level: Variable within the range of –30 dBFS to –10 dBFS.

J.17 De-emphasis: Software-selectable.

Filtering: RFI filtered. 
 

Digital Audio Outputs

Configuration: Two outputs, each stereo per the AES3 standard. The outputs can be independently set to emit the analog FM processed signal, the digital radio processed signal, or the low-delay monitor signal. The FM processed signal can be configured in software as flat or pre-emphasized to the chosen processing pre-emphasis (50μs or 75μs). The digital radio processing chain receives the output of the multiband limiter and processes it through a look-ahead true peak limiter that operates in parallel with the main FM peak limiting system. The DR and FM signals are always simultaneously available. Each output can apply J.17 pre-emphasis if desired.
 
Sample Rate: Internal free running at 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz, selected in software. (Use 44.1 kHz or higher for best peak control.) Can also be synced to the AES3 SYNC input or the AES3 digital input at 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz, as configured in software. 

Word Length: Software selected for 24, 20, 18, 16 or 14-bit resolution. First-order highpass noise-shaped dither can be optionally added, dither level automatically adjusted appropriately for the word length. 

Connector: XLR-type, male, EMI-suppressed. Pin 1 chassis ground, pins 2 and 3 trans- former balanced and floating, 110Ω impedance. 

Output Level (100% peak modulation): –20.0 to 0.0 dBFS software controlled. 

Filtering: RFI filtered. 

Frequency Response (Digital Audio Output (from Digital Radio Processing Chain)): For output sample rates of 44.1 kHz and above, the frequency response from input to DR-configured output is ±0.10 dB, 2.0 Hz - 20 kHz; flat or with J.17 pre-emphasis applied. The user may specify lowpass filtering to constrain the bandwidth to 15, 16, 17, 18, or 19 kHz. 

Relative Time Delay between FM and HD Outputs: Depends on setting of analog processing channel diversity delay. Once set, this delay is constant regardless of processing preset in use.
 

Wordclock/10 MHz Sync Reference

Configuration: Accepts 1x wordclock or 10 MHz reference signals, automatically selected. The DSP master clock can be phase-locked to these signals, which in turn phase-locks the 19 kHz pilot tone frequency, facilitating singe-frequency network operation. The digi- tal output sample frequency can also be locked to these signals. 

Level: Unit will lock to 1x wordclock and 10 MHz squarewaves and sinewaves having a peak value of 0.5 V to 5.0 V. 

Connector: BNC female, grounded to chassis, non-terminating to allow reference signals to be looped through via an external BNC “tee” connector (not supplied).
 

AES3id Input

Configuration: The Wordclock/10 MHz Sync Reference can also be configured as an AES3id digital audio input to drive the input of the stereo encoder. This facilitates a “rat- ings encoder loop-through” connection, where the input of the ratings encoder is driven from one of the 5700i’s AES3 outputs and the encoder’s output is returned to the AESid input.

Connector: BNC female, grounded to chassis, terminated with 75Ω. For short cable runs, there is usually no problem in driving this with an AES3 (110Ω) signal. If the cable is long enough to cause digital audio reception errors due to impedance m.ismatch, a 110Ω/75Ω transformer should be placed in-line.
 

Composite Baseband Outputs

Configuration: Two outputs, each with an independent software-controlled output level control, output amplifier and connector. 

Source Impedance: 0Ω voltage source or 75Ω, jumper-selectable.

Load Impedance: 37Ω or greater. Termination not required or recommended. 

Maximum Output Level: +16.0 dBu (13.82Vp-p). 

Pilot Level: Adjustable from 6.0% to 12.0%, software controlled. 

Pilot Stability: 19 kHz, ±1.0 Hz (10 degrees to 40 degrees C). 

D/A Conversion: 24-bit
 
Signal-to-Noise Ratio: >= 85 dB (Bypass mode, de-emphasized, 20 Hz – 15 kHz band- width, referenced to 100% modulation, unweighted). Distortion: <= 0.02% THD (Bypass mode, de-emphasized, 20 Hz – 15 kHz bandwidth, referenced to 100% modulation, unweighted). 

Stereo Separation: >50 dB, 20 Hz – 15 kHz; 60 dB typical.

Crosstalk-Linear: <= –80 dB, main channel to sub-channel or sub-channel to main channel (referenced to 100% modulation). 

Crosstalk-Non-Linear: <= –80 dB, main channel to sub-channel or sub-channel to main channel (referenced to 100% modulation). 

38 kHz Suppression: >= 70 dB (referenced to 100% modulation). 

76 kHz & Sideband Suppression: >= 80 dB (referenced to 100% modulation). 

Pilot Protection: 60 dB relative to 9% pilot injection, ±250 Hz (up to 2 dB composite proc- essing drive). 

Subcarrier Protection (60-100 kHz): >= 70 dB (referenced to 100% modulation; with up to 2 dB composite limiting drive; measured with 800 line FFT analyzer using “maximum peak hold” display). 

57 kHz (RDS/RBDS) Protection: 50 dB relative to 4% subcarrier injection, ±2.0 kHz (up to 2 dB composite processing drive). Connectors: Two BNC, shell connected to chassis ground, EMI suppressed.

Maximum Load Capacitance: 0.047 microfarad (0Ω source impedance). Maximum cable length of 100 feet/30 meters RG–58A/U. 

Filtering: RFI filtered.
 

Subcarrier (SCA) Inputs

Configuration: Two subcarrier inputs sum directly into composite baseband outputs; COMPx LVL control settings have no effect on the absolute subcarrier levels. 

Impedance: 600Ω 

SCA Sensitivity: Variable from <100 mV p-p to >10 V p-p to produce 10% injection assuming 100% modulation = 4 V p-p at the 5700i’s composite outputs. Rear-panel accessible PC-board-mounted trim pots allow user to adjust the sensitivities of the two SCA in- puts. 

Connectors: Two BNC, shell connected to chassis ground, EMI suppressed.

19 kHz Pilot Reference: SCA2 input can be re-jumpered to provide a 19 kHz pilot reference output.
