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
•ACU16-C
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
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 1.6m
3
/min or higher and a maximum static pressure
of 5mmH
2
O or higher.
Anmerkungen zum Rackeinbau des Geräts
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
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.
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 1,6m
3
/min und einen statischen Druck von
5mmH
2
O oder mehr erzeugen.
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.
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 1,6m
3
/min et une pression statique de
5mmH
2
O ou plus.
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.
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 1.6m
3
/min o superior con una presión estática mínima de 5
mm H

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
Wenn 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
Typenschild.
•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.

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

Cautions
Installation
•Keep this unit away from the following locations:
—Locations exposed to oil splashes or steam, such as near cooking stoves, humidifiers, etc.
—Unstable surfaces, such as a wobbly table or slope.
—Locations exposed to excessive heat, such as inside a car with all the windows closed, or
places that receive direct sunlight.
—Locations subject to excessive humidity or dust accumulation.
•Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A
damaged power cord is a potential fire and electrical shock hazard.
•Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard.
•This unit has ventilation holes to prevent the internal temperature from rising too high. Do
not block them. Blocked ventilation holes are a fire hazard. In particular, do not operate the
unit while it’s on its side, is upside down, or while it’s covered with a cloth or dust sheet.
•When installing the unit in a rack, you must use the rack-mounting screw holes at the rear
in addition to those on the front panel.
•When rack-mounting or stacking several units, always leave at least 1U (i.e., about 4.5 cm)
of free space above and below the unit for normal ventilation. If the airflow is restricted, the
unit may overheat, which could cause a fire.
•To relocate the unit, turn the power switch off, remove the power plug from the AC outlet,
and remove all connecting cables. Damaged cables may cause fire or electrical shock.
•This unit is equipped with a dedicated ground connection to prevent electrical shock.
Before connecting the power plug to an AC outlet, be sure to ground the unit. If the power
cord has a three-pin plug, it will provide sufficient grounding so long as the AC outlet is
grounded correctly.
Operation
•If you know you will not use this unit for a long period of time, such as when going on vaca-
tion, remove the power plug from the AC outlet. Leaving it connected is a potential fire haz-
ard.
