Introduction About the documentation This document explains mainly the operation and specifications of the ACD1 amplifier control device itself. When using the ACD1, you will also need to consult various manuals other than this document.
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.
Controls and Connectors Front Panel q w e r t q 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 Identify 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.
Controls and Connectors Rear Panel y u i !2 o !0 !1 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.
Panel operations By pressing buttons on the panel you can monitor or control various parameters of the ACD1 itself or of the connected amplifiers. The following parameters can be monitored/controlled. Category Sub category Operation performed 1. Scene (page 10) Recall Recalls a scene on the specified amplifier. Store Saves a scene for the specified amplifier. 2. Amp Control (page 11) On/Standby Switches the power of the specified amplifier between On and Standby.
Panel operations The main roles of each button are as follows. Button Role [NEXT] Moves to the next screen or parameter. [BACK] Moves to the previous screen or parameter. [▲INC/YES] Increments the value of a parameter (INC) or responds YES in response to a confirmation message. [▼DEC/NO] Decrements the value of a parameter (DEC) or responds NO in response to a confirmation message. Press the [▲INC/YES] button Press Increments the value of a parameter.
Panel operations 5. Use the [▲INC/YES] / [▼DEC/NO] buttons to select the ID of the amplifier for which you want to store settings. 6. Press the [NEXT] button to move to the scene number. 7. Use the [▲INC/YES] / [▼DEC/NO] buttons to select the scene number that you want to store. 8. Press the [NEXT] button to move to . 9. Press the [▲INC/YES] button to move to the screen where you can specify the scene name. 10. Use the [▲INC/YES] / [▼DEC/NO] buttons to edit the first character of the scene name. 11.
Panel operations Scene (“1. Scene”) Here’s how to recall or store scenes for a specified amplifier. 1.Scene å Recall ■ Recalling a scene (“1. Scene” ➝ “Recall”) Amp ID: 01 å 01:Scene Name Recalls a scene for the specified amplifier. Parameter Amp ID Range 00–39, ALL Attributes of the scene Explanation Selects the ID of the amplifier for which to recall a scene. If you select “ALL,” the correspondingly-numbered scene will be recalled for all amplifiers.
Panel operations Controlling an amplifier (“2. Amp Control”) These settings allow you to control an amplifier connected to the ACD1. 2.Amp Control å Standby ■ Power on/standby (“2. Amp Control” ➝ “Standby”) Switches the power of the specified amplifier between On and Standby. Parameter Range Amp ID: 01 å Standby Explanation Amp ID 00–39, ALL Selects the ID of the amplifier whose power will be switched. If you select “ALL,” the power of all amplifiers will be switched to the specified state.
Panel operations Amplifier output monitor (“3. Output Monitor”) This indicates the output level of the amp connected to the ACD1. 3.Output Monitor å ■ Amplifier output (“3. Output Monitor”) Displays the output level for each channel of the specified amplifier. Parameter Range Amp ID: A~B~ 01 å Explanation Amp ID 00–39 Selects the ID of the amp whose output level you want to view. Level 0 Nothing will appear in the meter if the level is below 0 dBu.
Panel operations ■ Identify (“4. Device Setup” ➝ “Identify”) Blinks the “Identify” icon of the corresponding ACD1 in Amp Editor. Identify ON å Parameter Identify Range ON/OFF Explanation If this is [ON], the “Identify” icon of the corresponding ACD1 in Amp Editor will blink. Turning this [OFF] will defeat the blinking. Utility (“5. Utility”) Here you can make overall settings for the ACD1 and view various types of information. 5.Utility å Battery ■ Backup battery check (“5.
Panel operations ■ LCD backlight (“5. Utility” ➝ “LCD Backlight”) This specifies the lit status of the ACD1’s LCD backlight. Parameter LCD Backlight Range LCD Backlight ON å Explanation ON The backlight will stay lit. Auto OFF The backlight will go dark automatically. It will light when you perform a panel operation, and will automatically go dark ten seconds afterward. ■ Restricting panel operations (“5. Utility” ➝ “Panel Operation”) Here you can turns panel operation lock on/off.
Panel operations ■ Enabling scene recall operations via EMG commands (“5. Utility” ➝ “EMG Scene Setup”) Specifies whether the EMG scene will be recalled when the EMG (Emergency) signal is received. The following three types of EMG signal can be received.
Panel operations ■ GPI IN calibration (“5. Utility” ➝ “GPI Calibration”) Calibrates the detected range of the [GPI IN] connector input voltage. Parameter Range Port No.: 3 Min:3.4V->4.2V å Explanation Port No. 1–4 Selects the port of the [GPI IN] connector that will be calibrated. Minimum/maximum value setting Min/Max Selects whether you will be setting the minimum (Min) or maximum (Max) value for the input voltage. Voltage value -- Indicates the input voltage.
Panel operations ■ Port settings for an external controller (“6. Network Setup” ➝ “IP Ctrl Port #”) Here you can specify the port number that will be used to control the ACD1 from an external device such as an AMX or Crestron unit. Parameter Port No. Range 49153–50049 IP Ctrl Port # 49153 å Port number (hexadecimal) Specifies the ACD1’s port number. Change the port number if there are other devices (other than the ACD1) that use the same port number.
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.
Connector wiring 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. GND OUT GND IN 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.
Connector wiring 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.
Appendix Display messages Messages that may appear in the ACD1’s display and the appropriate responses are listed below. For more about alert messages, refer to the Amp Editor owner’s manual. Message Response Panel locked! To prevent unintended operation, panel operations have been locked by the Panel Operation setting. To temporarily defeat Panel Operation, hold down both the [▲INC/YES] / [▼DEC/NO] buttons for at least three seconds.
Appendix Troubleshooting Symptom Possible causes Response All scene data saved in the ACD1 has disappeared The power was turned off while the ACD1’s data was being saved Once again synchronize the unit with Amp Editor to transmit the settings from Amp Editor. The internal battery has run down Go to “5. Utility” ➝ “Battery” to check the battery status.
