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.

Controls and Connectors
yGround 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.
•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).
!0 [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).
!1 [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.
• Use a UTP cable in which all eight pins are connected.
!2 [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.
Be sure to use the supplied Euroblock connector. If you lose the connector, contact your Yamaha dealer.
1. Loosen the terminal screws.
• Use a slotted screwdriver with a blade approximately 2 mm wide.
2. Insert the cables.
3. Securely tighten the terminal screws.
Pull the cables (not too strongly) to confirm that they are securely connected.
4. Connect the Euroblock plug to the ACD1’s [GPI] connector / [FAULT OUTPUT] connector.
Euroblock plug connection
● 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.
•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).
• If you use stranded wire, do not tin (plate with solder) the exposed end.

Connect GPI (General Purpose Interface) devices (e.g., control-
lers) to the rear panel [GPI] connector.
You can use GPI to send or receive control signals to or from an
external device.
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.
•AEuroblock plug is used for connection to the [GPI] connector.
Euroblock connection methods are described in “Euroblock plug connection” (page 18) in this manual.
• 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.”
•To adjust (calibrate) the range over which the input voltage to the [GPI] connector is detected, refer to “5. Utility” (page
13).

You can connect a lamp etc. to the rear panel [FAULT OUTPUT] connector to
indicate that an abnormality has occurred.
The [FAULT OUTPUT] connector consists of NO (Normally Open), C (Common), and
NC (Normally Closed). The [FAULT OUTPUT] connector is a relay circuit, and oper-
ates as follows.
The relay contacts used in the [FAULT OUTPUT] connector are rated for a load of 1A, DC 30V. Do not apply a load that
exceeds this rating.
Use Amp Editor to make settings for the [FAULT OUTPUT] connector.
Euroblock plugs are used for the [FAULT OUTPUT] connector. Euroblock connection methods are described in “Euroblock
plug connection” (page 18) in this manual.
• In Amp Editor’s [Device Setup] menu ➝[Alert Setup], you can set Type to Fault so that a fault can be indicated by a con-
nected lamp, etc. For details on making settings, refer to the “Amp Editor owner’s manual.”
