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.

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.

Notes on rack-mounting the unit

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.

Anmerkungen zum Rackeinbau des Geräts

We nn 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 Te mperatur 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.

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

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.

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 1.6m of 5mmH2O or higher.

/min or higher and a maximum static pressure

We nn 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 1,6m 5mmH2O oder mehr erzeugen.

Notas acerca de la instalación en rack de la unidad

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.

Important Note for PC-N Series Power

Ampliﬁer Users

When you are using the ACU16-C connected to a PC9500N or PC4800N power ampliﬁer, the NetworkAmp Manager's meter may not display the correct value, depending on your power ampliﬁer. Please check your power ampliﬁer for the following items to ﬁnd out whether the problem has been ﬁxed on your ampliﬁer:

Locate the product serial number label on the packing container or on the rear panel of the power ampliﬁer.

•If the ﬁrst two alphabetical letters in the serial number are IL, IM, IN, IO, IP, IX, IY, IZ, or JH, the problem may not have been ﬁxed on the ampliﬁer. Otherwise, you can assume that the problem has been ﬁxed on your ampliﬁer.

• On units that have a serial number that begins with any of the letter combinations described above, if there is a green round sticker adjacent to the serial number label, the problem has been ﬁxed on the unit.

If the problem has not been ﬁxed on your power ampliﬁer, contact your Yamaha dealer.

Wichtiger Hinweis für den Einsatz von

Endstufen der PC-N-Serie

We nn Sie den ACU16-C an eine Endstufe des Typs PC9500N oder PC4800N anschließen, zeigen die Meter von NetworkAmp Manager eventuell nicht den richtigen Wert an. Wenn das bei Ihnen der Fall ist, können Sie folgendermaßen ermitteln, ob das Problem der Endstufe behoben werden muss:

Bringen Sie die Seriennummer Ihrer Endstufe in Erfahrung. Diese ﬁnden Sie auf dem Lieferkarton und dem rückseitigen Ty penschild.

•Wenn die ersten beiden Buchstaben der Seriennummer „IL”, „IM”, „IN”, „IO”, „IP”, „IX”, „IY”, „IZ” oder „JH” lauten, bedarf die Endstufe eventuell noch einer Aktualisierung. Andernfalls können Sie davon ausgehen, dass das Problem bereits behoben wurde.

•Auf Geräten, deren Seriennummer mit den oben erwähnten Buchstaben beginnt und bei denen das Problem bereits behoben wurde, beﬁndet sich neben dem Typenschild ein runder grüner Aufkleber.

Fehlt dieser Aufkleber auf Ihrer Endstufe, so wenden Sie sich bitte an Ihren Yamaha-Händler.

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.

Nota importante para los usuarios de

los ampliﬁcadores de la serie PC-N

Si utiliza el ACU16-C conectado a un ampliﬁcador PC9500N o PC4800N, el indicador NetworkAmp del Manager puede que no visualice el valor correcto, dependiendo de su ampliﬁcador. Compruebe los siguientes elementos en su ampliﬁcador para saber si el problema se ha solucionado:

Localice la etiqueta del número de serie del producto en el embalaje o en el panel posterior del ampliﬁcador.

•Si las dos primeras letras del número de serie son “IL”, “IM”, “IN”, “IO”, “IP”, “IX”, “IY”, “IZ” o “JH”, es posible que el problema no se haya solucionado en el ampliﬁcador. De lo contrario, puede asumir que el problema se ha solucionado en el ampliﬁcador.

• En las unidades con números de serie que empiecen por cualquier serie de letras mencionada, si observa un punto verde al lado de la etiqueta del número de serie, el problema se ha solucionado en la unidad.

Si el problema persiste en el ampliﬁcador, contacte con su distribuidor Yamaha.
