ACU16-C/NHB32-C

Owner’s Manual Addendum

Please make the following changes and additions to the ACU16-C/NHB32-C owner’s manual. Some of these are due to the ACU16-C/NHB32-C system software upgrade, while others are corrections and supplementary explanations.

Changes due to the software upgrade

Support for CobraNet “Low Latency” (system software v1.10)

In conjunction with the upgrade to system software V1.10, the latency setting that had been fixed at 5.33 ms can now be selected from three choices (5.33 ms/2.67 ms/1.33 ms). This allows even lower-latency distribution of audio signals. In addition, you can now make connections at the desired latency to digital mixers such as the PM5D or digital mixing engines such as the DME64N/24N via the Yamaha “MY16-C” card.

Changing the latency can be done in conjunction with NetworkAmp Manager V1.1.0E. For the procedure, refer to the NetworkAmp Manager owner’s manual (PDF format).

The latency and audio bit depth settings will determine the limits on the number of channels that can be distributed in one bundle, and the number of bundles that can be distributed.

• NHB32-C

		20-bit		24-bit
Latency
	Channels per	Maximum number of bundles	Channels per	Maximum number of bundles
	bundle	(total of input and output)	bundle	(total of input and output)
5.33ms	8	8	7	8
2.67ms	8	8	8	8
1.33ms	8	4	8	4

• ACU16-C

	Latency	Maximum number of
		bundles (input only)
	5.33ms	4
	2.67ms	4
	1.33ms	4

If two or more different latencies exist in a CobraNet network, it may become impossible for the various devices to communicate correctly. You must make sure that all CobraNet devices in a single network have the same latency setting.

Additions and corrections

Cable Length & Switching Hubs

The maximum length of a cable used in a 100Base-T Ethernet network is 100 m (a maximum of 2 km for a multimode optical fiber cable), but depending on the type of cable used and on the performance of the switching hub, there are cases in which this length cannot be guaranteed. Three or four switching hubs can be connected, but this also will depend on the performance of the switching hub.

“System Requirements (NetworkAmp Manager)” (page 10)

The following items have been added to the operating requirements for NetworkAmp Manager.

•If your computer has HyperThreading Technology, you must disable it when connecting via USB.

•This software cannot be used on a computer that has multiple CPUs (e.g., Intel’s Xeon processor or AMD’s Opteron processor).

•This software cannot be used on a computer that has a dual core CPU (e.g., Intel’s Pentium-D processor or AMD’s Athlon64 x2 processor).

•This software cannot be used on a computer running Windows XP x64 Edition.

“Installing Acrobat Reader” (page 12)

Incorrect—To view the Network Amp Manager Owner’s Manual, you’ll need to install the Adobe Acrobat Reader software, which is included on the CD-ROM. If you already have this software installed, skip this section.

Correct—To view the NetworkAmp Manager Owner’s Manual (PDF format), Adobe Reader software (free of charge) must be installed. If you don’t have Adobe Reader, please download it from the Adobe Corporation’s website. http://www.adobe.com

“PRIMARY & SECONDARY CobraNet ports” (page 22)

Incorrect—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the SECONDARY port and operation will continue uninterrupted.

Correct—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16- C uses the PRIMARY port. However, if system problems such as port malfunction or broken cable occur in the PRIMARY port, it will automatically switch to the SECONDARY port. The audio signal will be momentarily interrupted, but the duration of the interruption will depend on the performance and settings of the hub, and on the structure of the system.

“Introduction” (page 25)

Incorrect—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 512 CobraNet audio channels and 512 AES/EBU format inputs and outputs.

Correct—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging a maximum (total inputs and outputs) of 256 channels of CobraNet audio and AES/EBU audio.

“CobraNet Primary & Secondary” (page 35)

Incorrect—In the first example, if a primary connection fails, the system automatically switches to secondary and operation continues uninterrupted. However, if the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B.

Correct—In the first example, if a primary connection fails, the system automatically switches to secondary. However if the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B.

Be aware that with either connection, the time required in order to switch between primary and secondary will depend on the performance and settings of the hub.

“CobraNet Primary & Secondary, Ex. 2” (page 35)

In consideration of a case in which the primary connection fails, connect switching hub A and switching hub B.

Notes on rack-mounting the unit

E

If you install the ACU16-C/NHB32-C along with another ACU16-C/NHB32-C or other device in a rack that is not well ventilated, the temperature inside the rack may rise due to the heat generated from the devices and the devices may be unable to perform properly. When you rack-mount the unit, be sure to keep a gap of 1U (4.5cm) above and below the unit for better ventilation. Also, install the ventilation panels in these gaps or remove the partition panels.

If the temperature inside the rack is expected to be 40°C or higher (in this case, the room temperature is generally about 30°C or higher), install the fan kit on the top shelf of the rack, and install the ventilation panels between devices or remove the partition panels. The fan kit must generate a maximum wind of 1.6m3/min or higher and a maximum static pressure of 5mmH2O or higher.

Anmerkungen zum Rackeinbau des Geräts	D

Wenn Sie den ACU16-C/NHB32-C gemeinsam mit einem anderen ACU16-C/NHB32-C oder einem Gerät mit mangelhafter Lüftung in ein Rack einbauen, könnte die Temperatur im Innern des Racks rapide ansteigen und Ausfälle der vorhandenen Geräte verursachen. Lassen Sie über und unter Geräten in einem Rack jeweils 1HE (4,5cm) frei, um eine ausreichende Luftzirkulation zu gewährleisten. In diesen Öffnungen müssen Lüftungsblenden angebracht werden. Außerdem sind eventuell vorhandene Trennplatten zu entfernen.

Wenn die Temperatur im Innern des Racks die 40°C-Marke zu übersteigen droht (was der Fall ist, wenn die Raumtemperatur mindestens 30°C beträgt), müssen Sie ganz oben im Rack eine Lüftereinheit und zwischen den Geräten Lüftungsblenden einbauen. Trennplatten zwischen diesen Partien müssen entfernt werden. Die Lüftereinheit muss einen Luftstrom von mindestens 1,6m3/min und einen statischen Druck von 5mmH2O oder mehr erzeugen.

Remarques concernant l’installation de l’unité dans un rack

F

Si vous installez l’ACU16-C/NHB32-C dans le même rack qu’un deuxième ACU16-C/NHB32-C ou tout autre dispositif avec une ventilation autonome plutôt limitée, la température au sein du rack pourrait très vite monter à des valeurs qui empêchent les unités de fonctionner correctement. De ce fait, pour le montage en rack, il convient de laisser un espace d’1U (4,5cm) au-dessus et en dessous de tels dispositifs pour assurer une bonne circulation d’air frais. De plus, il faut couvrir les ouvertures ainsi laissées avec des panneaux de ventilation. Retirez toute cloison éventuellement présente entre deux unités.

Si la température au sein du rack risque de monter au-delà de 40°C (auquel cas la température ambiante s’élève à 30°C ou plus), installez un kit de ventilation en haut du rack et des panneaux de ventilation entre les unités. Retirez en outre les cloisons qui les séparent. Le kit de ventilation doit générer un flux d’air supérieur à 1,6m3/min et une pression statique de 5mmH2O ou plus.

Notas acerca de la instalación en rack de la unidad

S

Si instala el ACU16-C/NHB32-C junto con otro ACU16-C/ NHB32-C u otro dispositivo en un armario rack que no esté correctamente ventilado, la temperatura en el interior del armario puede elevarse debido al calor generado por los propios dispositivos y afectar al correcto funcionamiento de los mismos. Cuando instale la unidad en rack, asegúrese de dejar una separación de 1U (4.5cm) por encima y por debajo de la unidad con el fin de conseguir una correcta ventilación. Además, instale los paneles de ventilación en estas separaciones o elimine los paneles de partición.

Si se calcula que la temperatura en el interior del rack sea de 40°C o más (en este caso, cuando la temperatura de la habitación es de 30°C o superior), instale el kit de ventilación en la parte superior del armario rack e instale los paneles de ventilación entre los dispositivos o elimine los paneles de división. El kit de ventilación debe generar un caudal mínimo de 1.6m3/min o superior con una presión estática mínima de 5 mm H2O o superior.

Remarque importante à l’attention des utilisateurs d’un amplificateur de puissance de la série PC-N

Quand l’ACU16-C est branché à un amplificateur de puissance PC9500N ou PC4800N, il se peut (selon l’ampli de puissance) que l’affichage de niveau de NetworkAmp Manager n’indique pas la valeur correcte. Contrôlez alors le numéro de série de votre amplificateur comme suit pour vérifier si ce problème doit être corrigé ou non:

Vérifiez le numéro de série de l’amplificateur sur l’emballage ou le panneau arrière de l’appareil.

•Si les deux premières lettres du numéro de série correspondent à “IL”,“IM”,“IN”,“IO”,“IP”,“IX”,“IY”,“IZ” ou “JH”, le problème n’a peut-être pas été corrigé sur l’amplificateur. Si les lettres initiales du numéro de série diffèrent des caractères ci-dessus, vous pouvez partir du principe que le problème a été corrigé sur votre amplificateur.

•Certains amplificateurs dont le numéro de série commence par une paire de lettres mentionnée ci-dessus pourraient comporter une vignette ronde et verte collée à côté de l’étiquette du numéro de série. La présence de cette vignette signifie que le problème a été corrigé sur l’appareil en question.

Si le problème n’a pas été corrigé sur votre amplificateur de puissance, contactez votre revendeur Yamaha.
