Audio Processor Quick Setup
This features provides a guided, systematic procedure for setting up your 8700i Audio Processor.

Factory Presets & LESS-MORE Control
The OPTIMOD 8700i comes with a variety of factory presets which you can use as basis to create your own signature sound. Orban is happy to help you find the perfect setup for your station. Easy LESS-MORE adjustment of the dynamics processing lets anyone get excellent results, while audio processing experts can fine-tune to their exact preferences with Intermediate or Advanced Control.

Xponential Loudness™ Algorithm
The Xponential Loudness™ algorithm reduces listening fatigue and actually improves listeners’ hearing using adaptive psychoacoustics. It revives music that has been “hypercompressed” in mastering and/or passed through lossy compression, like MP3. It’s like an audio magnifying glass that brings out hidden detail, clarifying audio and inspiring audiences to listen longer.

Subharmonic Synthesizer
The Subharmonic Synthesizer creates energy one octave below program energy in the range of 50-90 Hz when such energy is not present at the input and when music is detected. It adds punch and slam to older material while retaining musicality. 

“Multipath Mitigator” Left/Right Phase Skew Correction
Applied to both the analog and digital radio processing chains, the phase skew corrector minimizes L–R energy that can cause multipath distortion while preventing comb filtering in mono receivers and stereo receivers when they blend.

“True Peak” Control
”True Peak” Control is available for the digital radio processing with an accuracy of better than 0.5 dB. For typical program material, accuracy is 0.2 dB.

ITU BS-412 Multiplex Power Control
An improved BS-412 Multiplex Power Controller provides a new user-adjustable, program-adaptive algorithm to make operation smoother and more subtle.

ITU-R BS.1770-4 Loudness Control
Loudness Control is available for digital radio and analog radio processing chains in countries that enforce a BS.1770 loudness limit on digital and/or analog radio broadcasts.

Composite Limiter/Clipper
A patented “Half-Cosine Interpolation” composite limiter providing excellent spectral protection of the pilot tone and SCAs (including RDS). If you prefer the sound of conventional composite clipping, we also offer a defeatable composite clipper with spectral protection for the pilot tone and subcarriers. The composite clipper drives the composite limiter, which serves as an overshoot compensator for the composite clipper when it is active.

SSB Stereo Encoder Operation
Allows its stereo encoder’s stereo subchannel modulator to operate in an experimental compatible single sideband/vestigial sideband mode. In SSB mode, the sub-channel modulator acts as a pure SSB generator for L–R material in the frequency range of 150 Hz to 17 kHz and as a vestigial sideband generator below 150 Hz.

Low-Delay DJ Monitor Output
The MX limiter, Multipath Mitigator, and subharmonic synthesizer add delay that makes it impractical for talent to monitor all of the processing structures off-air with headphones. A new, dedicated headphone monitor chain (with about 6 ms delay) provides a full five-band FM processor that lets you dial in your preferred amount of “FM clipper sound.”

Streaming Monitor Output
Used with the 8700i’s remote control application, the streaming monitor facilitates checking or improving your station’s signature sound when you are unable to receive the 8700i processed FM signal off-air. The steaming feature allows you to monitor several points within 8700i. The MP3 and OPUS codecs and the Icecast2 and SHOUTcast2 streaming protocols are supported, allowing streaming directly to the client PC via your LAN or the Internet.

Dante™ Audio-Over-IP Connectivity
Dante provides a dual-redundant Ethernet connection for two stereo audio inputs and two stereo outputs, each with a dedicated level control. Sample rate conversion is provided for both the inputs and the outputs. Full AES67 compatibility is provided.

Digital MPX
The 384/192 kHz AES3 digital composite output that is compatible and interoperable with the 192 kHz standard being implemented by several transmitter manufacturers.

10 MHz/Wordclock Reference Input
10 MHz/Wordclock Reference Input: A reference input allows the internal DSP clock, the stereo pilot tone frequency and digital composite output sample rate to be locked to a 10 MHz or 1 x wordclock reference signal, facilitating single-frequency-network (SFN) and near-single-frequency-network (N-SFN) operation.

Safety Bypass Relays
Analog and AES3 digital inputs and outputs have hard-wire safety bypass relays in case of hardware or power failures.

Dual Power Supplies
The 8700i’s dual power supplies with independent AC line inputs provide redundant operation to ensuring maximum uptime. Both power supplies are monitored permanently and, in case of failure, an alarm is generated.

RDS
The 8700i Audio Processor has a built-in full-featured RDS/RBDS generator that supports static and dynamic RDS values.

Bypass Test Mode and Tone Generator
A Bypass Test Mode can be invoked locally, by remote control or by automation to perform a broadcast system test or to compare easily original and processed sound. A built-in line-up tone generator facilitates quick and accurate level setting.

SNMP Support
The SNMP (Simple Network Management Protocol) feature allows you to monitor your OPTIMOD’s status and to send alarm notifications via your OPTIMOD’s Ethernet connection to your network.

Remote Control or front panel operation
You can operate and configure the 8700i comfortably via the supplied Windows PC Software using your local network or the Internet. Alternatively all functionalities are also available via the front panel with its colored display.
