Supported amplifiers

As of September 2009, the following amplifiers support connection with the ACD1.

• XP series : XP7000, XP5000, XP3500, XP2500, XP1000
• XM series : XM4180, XM4080
• XH series : X H 2 0 0

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 amplifiers connected to a [MONITOR/REMOTE] connector, the Amp ID is determined by the connector that is used.

Controls and Connectors

Front Panel

YAMAHA ① ② ③ ④ ⑤ ACD1 POWER ACD1

① Display

This shows information about the scene, the ACD1 itself, or the connected amplifiers. This will light red when an abnormality (a WARNING or higher alert) occurs. This will also blink blue and white when the Identity operation is performed in Amp Editor.

When you turn on the power, a HOME screen like the following will appear. The HOME screen shows the Device ID and the name of the ACD1 specified by Amp Editor.

Device ID Device Label ..... The name of the ACD1 assigned by Amp Editor is displayed. If characters not supported by the ACD1 are used, "will be displayed in those locations.

② [BACK] button

Use this to move to the previous screen or parameter.

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.

Rear Panel

Diagram of an electronic device rear panel with labeled ports and connectors, including a 3D network interface and I/O port.

⑥ 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.

⑦ [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.

⑧ [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.

⑨ [GPI] connector

This Euroblock connector provides access to the unit's GPI (General Purpose Interface) interface for transfer of control signals 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,

1. Power-off the ACD1.

1. While holding down the [BACK] button, turn the power on.

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-mounting 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 ferrule whose conductor portion has an external diameter of 1.3 mm or less, and a length of approximately 5 mm (such as the Al0.5-6WH made by the Phoenix Contact corporation).

- If you use stranded wire, do not tin (plate with solder) the exposed end.

1. Loosen the terminal screws.

NOTE • Use a slotted screwdriver with a blade approximately 2 mm wide.

2 mm Loosen Slotted screwdriver Euroblock plug

GPI connector

Connect GPI (General Purpose Interface) devices (e.g., controllers) to the rear panel [GPI] connector.

You can use GPI to send or receive control signals to or from an external device.

GPI

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.
• F or 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 external GPI device, or send signals to an external GPI device. For details on making settings, refer to the "Amp Editor owner's manual."

● Example : Controlling the ACD1 from a switch

ACD1 +5V CPU← A/D 100k +V IN

● Example : Lighting the LED of an external device from the ACD1

ACD1 +5V +V 10 OUT CPU → Q Max. 75 mA

FAULT OUTPUT connector

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 operates as follows.

FAULT OUTPUT NO C NC

	Normal state Abnormal state Powered-off
NO Open Closed Closed
NC Closed Open Open

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.

NOTE In Amp Editor's [Device Setup] menu → [Alert Setup], you can set Type to Fault so that a fault can be indicated by a connected lamp, etc. For details on making settings, refer to the "Amp Editor owner's manual."

● Example : Using an LED to indicate normal/fault status of the ACD1
