AUDIO NETWORKING SIMPLIFIED
BSS and Crown feature products that include native Dante and AES67 AoIP technologies with legacy support for CobraNet in some products. Through the use of BLU link, they can also be programmed and controlled through HARMAN HiQnet Audio Architect™ software. By combining this range of audio transport solution options, users have incredible flexibility to choose the right product to solve the requirements of almost any job.
In addition, AMX SVSI Networked AV encoders and decoders can stream AES67-transported audio digitally to and from BSS Soundweb London Signal Processors. Since Soundweb London Signal Processors send and receive both AES67 and Dante simultaneously, the advanced functionality, offered by Dante, can be retained between compatible devices, such as other HARMAN AES67-compatible equipment. Support of HARMAN processor, amplifier and video products, including AMX SVSI Networked AV devices, utilizing AES67, brings seamless interoperability with other non-HARMAN AES67 compatible systems. This diagram illustrates a typical application utilizing HARMAN Networked AV:
FLEXIBLE AUDIO TRANSPORT SOLUTIONS
System designers face a wide variety of audio transport standard decisions, which drove HARMAN to develop a range of signal processing solutions to meet the needs of the most popular requirements.
Crown offers a range of models that support Dante, AES67 and CobraNet. In addition, Crown offers BLU link amplifiers, which can be paired with any Soundweb London processor allowing for an incredible amount of channel count and power options.
AMX SVSI video encoders and decoders now include AES67, allowing native audio integration with BSS and Crown to complete a fully integrated audiovisual system. This video offers an additional discussion on HARMAN Networked Audio solutions:
USB AUDIO
It’s often desirable to use a computer as a source of audio or as a recording device. The BSS BLU-USB allows up to eight channels of audio to be sourced from a PC/Mac and made accessible via BLU link to other devices on the same ring. Up to eight channels of audio can also be received by the computer from the BLU link ring for recording or monitoring purposes. This diagram illustrates a typical USB Audio solution:
DANTE
يوفّر دعم HARMAN لـ Dante للصوت عبر الشبكة إمكانية نقل الصوت من خلال معالجات BSS Soundweb London BLU-806DA، BLU-326DA، أو أجهزة BLU-DA إلى أي مضخّم Crown مزوّد بتقنية BLU link. تتيح معالجات Soundweb London هذه استخدام Dante لنقل الصوت بين عدّة مواقع، مع إمكانية توجيهها من خلال المحوّلات والبنية الأساسية للشبكة الموجودة. يمكن استخدامها أيضاً كجسر لتحويل صوت Dante إلى BLU link لإعادة توزيع صوتي منخفض التكلفة يصل إلى 60 جهازاً داخل رف أو غرفة.
بالإضافة إلى استخدام مضخّمات BLU link في نظام Dante، يمكن لمضخّمات Crown DriveCore Install (DCi) DA Series أيضاً استقبال صوت Dante مباشرة. جميع موديلات DCi DA قادرة على توفير صوت 70Vrms/100Vrms لكل قناة.
جديد: تحديث البرنامج الثابت لـ Dante Domain Manager لـ BSS و Crown
معالجات BSS SoundWeb London المزوّدة بـ Dante (BLU-806-DA، BLU-326-DA، BLU-DA) ومضخّمات Crown DCi-DA (8|600DA، 8|300DA، 4|1250DA ، 4|600DA، 4|300DA) ستدعم البرنامج الثابت Dante 4.0 من Audinate، الذي يتضمّن Dante Domain Manager. يوفّر Dante 4.0 هذه المميّزات الإضافية:
- توافق مع أنظمة تكنولوجيا المعلومات
- يمكن تشغيله على جهاز VM
- الإبلاغ عبر SNMP
- دعم Active Directory و LDAP
- توافق مع المدمّجين
- يمكن تقسيم نظام الصوت إلى "نطاقات" آمنة، لكل منها عمليات دخول آمنة للمستخدمين
- لوحة معلومات قابلة للتخصيص للدعم عن بعد
- توجيه الصوت عبر الشبكات الفرعية / WAN
- سجل تدقيق لاستكشاف الأخطاء وإصلاحها

NETWORK TRANSPORT EXPANSION OPTIONS USING BLU LINK
BLU link is a great compliment to other network transport formats, such as Dante. By using the appropriate BSS Soundweb London processor, Dante can be converted to BLU link for local distribution within a rack or rack room. Designing a system with this method can alleviate network congestion and expand system options to any BLU link-enabled amplifier, processor, or accessory. This system design approach works identically regardless of AoIP protocol.
Dante & AES67
AES67 is a standard for high-performance streaming audio-over-IP interoperability. It provides a common format to pass audio digitally between two or more different audio-over-IP systems.
Many AMX SVSI video encoders and decoders support AES67, in addition to traditional SVSI encoded audio. Additionally, Soundweb London processors support AES67 audio, allowing the processor to ingest audio from video components.
This means that audio from AMX Networked AV encoder sources can be broken away digitally and sent via AES67 to BSS Soundweb London devices. From there, it can be processed and sent via AES67 to AMX decoders and/or via Dante or BLU link to HARMAN amplifiers and processors.
The growing list of supported AMX SVSI video encoders/decoders have model names ending in the “A”. This diagram illustrates a typical application utilizing HARMAN Dante & AES67:
COBRANET
HARMAN’s support of CobraNet networked audio allows audio to be passed through BSS Soundweb London BLU-800 or BLU-320 processors into any Crown BLU link-enabled amplifier. Both the BLU-800 and BLU-320 make it possible to use CobraNet to pass audio between multiple locations, capable of being routed through switches and existing network infrastructure. They can also be used as a bridge to convert CobraNet audio to BLU link for low-cost audio redistribution of up to 60 devices within a rack or room.
In addition to using BLU link amplifiers in a CobraNet system, Crown I-Tech HD Series amplifiers can also receive CobraNet audio directly. All I-Tech HD models are capable of providing 70Vrms/100Vrms audio per channel. This diagram illustrates a typical application utilizing HARMAN CobraNet:
AVB
يمكن نقل إشارات صوت AVB عبر معالجات BSS Soundweb London BLU-805 أو BLU-325 إلى أي مضخّم Crown مفعّل لـ BLU link. يتيح كل من BLU-805 و BLU-325 استخدام AVB لنقل الصوت إلى عدة مواقع وتضمن القدرة على العبور عبر المحاويل والموجهات في بيئة الحرم الجامعي. يمكن استخدامهما أيضاً كجسر لتحويل صوت AVB إلى BLU link لإعادة توزيع صوتي منخفض التكلفة تصل إلى 60 جهازاً داخل رف أو غرفة.
بالإضافة إلى استخدام المضخمات المفعّلة لـ BLU link في نظام AVB، يمكن لمضخمات Crown DriveCore Install Network Display Series استقبال صوت AVB مباشرة وهي معتمدة من AVnu® Alliance للعمل مع حلول AVB أخرى. يتوفر نموذجان من سلسلة Install Network Display Series: 4|1250ND و 8|600ND. يوضح هذا الرسم التطبيق النموذجي باستخدام HARMAN AVB:
