Handling caution
• Condensation can occur in the device due to rapid, drastic changes in
ambient temperature—when the device is moved from one location to
another, or air conditioning is turned on or off, for example. Using the
device while condensation is present can cause damage. If there is reason
to believe that condensation might have occurred, leave the device for
several hours without turning on the power until the condensation has
completely dried out.
• Do not insert your fingers or hands in any gaps or openings on the device
(ports, etc.).
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into
any gaps or openings on the device (ports, etc.) If this happens, turn off the
power immediately and unplug the power cord from the AC outlet. Then
have the device inspected by qualified Yamaha service personnel.
• Do not rest your weight on the device or place heavy objects on it, and
avoid use excessive force on the buttons, switches or connectors.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.
Always turn the power off when the device is not in use.
The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualifi ed Yamaha service
personnel about replacing defective components.

For customers using the PC9500N, PC4800N, or PC3300N power amplifiers
If your system connects the PC9500N, PC4800N, or PC3300N power amplifiers to the ACD1, there may be cases in
which Amp Editor will not display the meters correctly for some power amplifiers. Please check whether this problem
has been corrected for the power amplifier you're using. If not, please contact your Yamaha dealer.
[Checking for the correction]
If the two alphabetical characters at the beginning of the serial number label on the back of the power amp are IL, IM, IN, IO, IP,
IX, IY, IZ, or JH, and no green circular label is affixed immediately nearby it, then the product has not been corrected.
For customers using the T5n, T4n, or T3n power amplifiers
When monitoring or controlling the T5n, T4n, or T3n power amplifiers, set the GAIN switch of the T5n, T4n, or T3n to
[26 dB] to avoid clipping if you plan to input signals with a maximum input level of +24 dBu.
When the power amplifier is connected to the ACD1, the electronic volume control inside the amplifier will become
effective, and the maximum input level will become +18 dBu if the GAIN switch has been set to [32 dB].
Included Accessories
• AC power cord • Euroblock connector (16P)

Backup battery
This device has a built-in backup battery that maintains data in internal
memory even when the device's power is switched off. The backup battery will
eventually become depleted, however, and when that happens the contents of
the internal memory will be lost.* To prevent loss of data be sure to replace the
backup battery before it becomes fully depleted. When the remaining capacity
of the backup battery becomes so low that it needs to be replaced a "Low
Battery", "Critical Battery" or "No Battery" message will appear on the display
during operation or when the device is powered on. If either of these
messages appears do not turn off the power and immediately transfer any data
you want to save to a computer or other external storage device, then have
qualified Yamaha service personnel replace the backup battery. The average
life of the internal backup battery is approximately 5 years, depending on
operating conditions.
* Data items maintained in the internal memory by the backup battery are as
follows:
• Current scene parameters and number.
• Device parameters (Device Setup, Utility, Network Setup, etc.).
