Introduction  
Terms  
This section explains terminology specific to the ACD1.  
Amp Editor  
This is computer application software. With this software, you can use your computer to monitor and control the ACD1 and  
the amplifiers connected to the ACD1.  
Scene  
Settings such as Power-On/Standby or mute for each amplifier are collectively called a “scene.” By recalling a scene, the  
saved settings can be immediately applied to the amplifiers. The ACD1 can specify 49 scenes for each connected amplifier.  
Scene link  
Settings for simultaneously recalling scenes for multiple amplifiers within an area are called a “scene link.” By recalling a  
scene link, scenes can be simultaneously recalled for multiple amplifiers. Scene links can be created and recalled using  
Amp Editor.  
Device ID  
This is an ID for uniquely identifying an ACD1 unit within a network. If there are duplicate IDs within an area, it will be  
impossible to monitor/control them from Amp Editor.  
Amp ID  
This is the ID of each amplifier connected to the ACD1. Amplifiers connected to the [DATA PORT] connector of the same  
ACD1 must be set to non-overlapping IDs using the [AMP ID] switch located on the rear panel of each amplifier. For ampli-  
fiers connected to a [MONITOR/REMOTE] connector, the Amp ID is determined by the connector that is used.

NOTE • If you press and hold down this button for three seconds or longer while the HOME screen is displayed, the Device ID  
setting screen will appear.  
e [INC/YES]/[DEC/NO] buttons  
Use these to increment or decrement (INC/DEC) the value of a parameter, or to respond YES/NO to a confirmation mes-  
sage.  
NOTE To temporarily unlock the panel operation, press and hold down both the [INC/YES] and [DEC/NO] buttons for at  
least three seconds to display the message “Unlock panel: Are you sure?”. Press the [INC/YES] button. The panel lock  
will be temporarily defeated until the power to the ACD1 is turned off.  
To reset the FAULT OUTPUT connector output (to connect NC and C), press and hold down the [BACK] and [DEC/NO]  
buttons simultaneously for a few seconds while the HOME screen is displayed to display the message “Reset FaultOut  
Are you sure?”. Then press the [INC/YES] button. This operation is effective only when the FAULT OUTPUT connector

NOTE • The settings at the time you powered-off are remembered. When you turn on the power again, the unit will start up with  
the same settings.You can use the “Last Mem. Resume” setting to set up the unit so that at startup it will recall the scene  
number selected before you turned off the power to the device.  
• If Last Mem. Resume is ON, data will be backed-up to internal memory at regular intervals, so you should not turn off the  
power within five seconds after operating a parameter.  
CAUTION  
• Do not turn off the power while the display indicates “Do not turn off!”

y Ground screw  
The AC power cord is a 3-wire type. If the AC outlet used is earthed (grounded), this device will be properly earthed as well.  
Also, grounding the screw sometimes reduces hum and interference noise.  
u [AC IN] connector  
Connect to the AC mains using the supplied AC power cable.  
First connect the power cord to the ACD1, then insert the power cord plug into an AC outlet.  
i [NETWORK] connector  
This is a 100Base-TX/10Base-T Ethernet connector for connection to a computer or other device in the network.  
NOTE • Use a UTP cable or STP cable for connection to the [NETWORK] connector. (Use an STP cable in countries where FCC  
regulations apply.) Since the ACD1 supports Auto MDI/MDI-X, it will automatically detect whether the connected cable is  
of the straight type or crossover type, and will configure itself to create the appropriate connection. Therefore, you can  
use either a straight or crossover cable.  
• The maximum length of a cable between a network switch and the ACD1 is 100 meters. Due to the quality of cables and  
network switch performance, however, proper operation at the maximum length cannot be guaranteed in some cases.  
o [GPI] connector  
This Euroblock connector provides access to the unit’s GPI (General Purpose Interface) interface for transfer of control sig-  
nals to and from external equipment. The ACD1 provides 4-port input and 4-port output. The +V terminals have an output  
voltage of 5 volts. The IN terminals detect voltage changes from 0V to 5V. The OUT terminals are open-collector outputs,  
and change between Open and Close. For details on connections and usage, refer to “Connector wiring” (page 18). For  
details on calibrating the [GPI IN] connectors, refer to “Utility” (page 13).  
! [FAULT OUTPUT] connectors  
This is a Euroblock connector that can inform an external device when an abnormality occurs with the ACD1’s CPU, or  
when there is an event for which Fault Output has been specified in the Alert Setup dialog box of Amp Editor. For details on  
connections and usage, refer to “Connector wiring” (page 18).  
! [DATA PORT] connector  
This is an RJ-45 connector that can be connected to a maximum of 32 PC-N/Tn series units so that they can be monitored/  
controlled from the ACD1. You can use CAT5 or better UTP straight cables to make daisy-chain connections for a maxi-  
mum of 500 meters.  
The Amp ID of amplifiers connected to this connector must be set to non-overlapping numbers in the range of 0 to 31.  
NOTE • Use a UTP cable in which all eight pins are connected.  
! [MONITOR/REMOTE] connector  
These are D-Sub 15-pin connectors that allow up to eight XP/XH/XM series units to be connected so that they can be mon-  
itored/controlled from the ACD1. You can use three-row D-Sub 15-pin straight cable to make a connection for a maximum  
of 50 meters.  
Amplifiers connected to these connectors will be assigned an Amp ID between 32 and 39 according to the connector to  
which they are connected.

Connector wiring  
This section explains how to wire the [GPI] and [FAULT OUTPUT] connectors located on the ACD1’s rear panel.  
Euroblock plug connection  
Be sure to use the supplied Euroblock connector. If you lose the connector, contact your Yamaha dealer.  
Cable preparation  
• To prepare the cable for attachment to a Euroblock connector, strip the wire as  
shown in the illustration, and use stranded wire to make connections. With a  
Euroblock connection, the stranded wire may be prone to breakage because of  
metal fatigue due to the weight of the cable or due to vibration. When rack-mount-  
ing your equipment, use a lacing bar when possible to bundle and fasten the cables.  
approx.  
5 mm  
• If cables will be frequently connected and disconnected, as in the case of a portable  
installation, we recommend that you use ferrules with insulation sleeves. Use a fer-  
rule whose conductor portion has an external diameter of 1.3 mm or less, and a  
length of approximately 5 mm (such as the AI0,5-6WH made by the Phoenix Con-  
tact corporation).  
1.3 mm  
or less  
approx.  
5 mm  
• If you use stranded wire, do not tin (plate with solder) the exposed end.  
CAUTION  
1.  
Loosen the terminal screws.  
NOTE • Use a slotted screwdriver with a blade approximately 2 mm wide.  
Slotted screwdriver

2.  
Insert the cables.  
3.  
4.  
Securely tighten the terminal screws.  
Pull the cables (not too strongly) to confirm that they are securely connected.  
Connect the Euroblock plug to the ACD1’s [GPI] connector / [FAULT OUTPUT] connector.

Voltage  
The ACD1 provides 4-port input and 4-port output.  
• The +V terminals have an output voltage of 5 V. A maximum total of 100 mA of current can be drawn.  
• The IN terminals detect voltage changes from 0 V to 5 V.  
• The OUT terminals are open-collector outputs. A maximum voltage of +12 V can be applied.  
• For each port, a maximum of 75 mA of current can flow.  
• Use Amp Editor to make settings such as parameter assignments.  
• A Euroblock plug is used for connection to the [GPI] connector.  
Euroblock connection methods are described in “Euroblock plug connection” (page 18) in this manual.  
NOTE • By specifying the input/output channels in Amp Editor, you can recall scenes or edit parameters from a connected exter-  
nal GPI device, or send signals to an external GPI device. For details on making settings, refer to the “Amp Editor owner’s  
manual.”
