Key Features - OPTIMOD-FM 8700i Audio Processor
Dual Power Supplies
The 8700i’s dual power supplies with independent AC line inputs provide redundant operation to ensuring maximum uptime.
Safety Bypass Relays
Analog and AES3 digital inputs and outputs have hard-wire safety bypass relays in case of hardware or power failures.
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 coming Fall 2017 via an easy, free software upgrade.
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 Reference Input
A 10 MHz reference input allows the stereo pilot tone frequency and digital composite output sample rate to be locked to a 10 MHz reference signal (like GPS), facilitating
single-frequency-network (SFN) and near-single-frequency-network (N-SFN) operation.
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 5ms delay) provides a full 5-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.
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.
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.
“Multipath Mitigator” Left/Right Phase Skew Correction
The phase skew corrector maximizes both FM and Digital Radio processing paths for the quality of a mono mixdown or blend that might occur in a receiver or player device.
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.
