Front and Rear Panels Front Panel fig.1 6 1 2 3 4 5 7 8 In some cases, it may be possible to make settings on the device connected via R-BUS to disable front panel operations. 1 PHANTOM Buttons 1–8 When connecting the XLR input jack to a device that requires phantom power, turn this on. When phantom power is being supplied, the PHANTOM indicator will light. Supplying phantom power to a dynamic mic or an audio playback device will cause malfunctions.
Front and Rear Panels 5 MANUAL Button Selects whether operation of the front panel PHANTOM buttons / PAD buttons / INPUT sensitivity knobs will be enabled or disabled. If you want to enable operation of these buttons/knobs, make the MANUAL indicator light. If you wish to remotely control the ADA-7000 from a device connected via the R-BUS connector, make the MANUAL indicator go dark. 6 CLOCK SOURCE Button Selects the source of the sampling clock.

To avoid malfunction, connect only the power supply cord that was supplied with the unit. 2 WORD CLOCK IN/OUT Connectors IN: When supplying a sampling clock from an external device to the ADA-7000, input the WORDCLOCK signal here. Use this when you want the reference clock to be another device that outputs a high-precision sampling clock, or when synchronizing to a device that has only a WORDCLOCK OUT.
Front and Rear Panels TERMINATOR Switch: Turn this on if the ADA-7000 is the last device in the word clock signal chain. Normally you will leave this turned on. Turn this off only if you are using a relay connector to distribute the word signal to other devices. fig.3a.e Sampling Clock Master Digtal Tape Recorder Connector TERMINATOR SWITCH: OFF WORD CLOCK IN ADA-7000 WORD CLOCK IN WORD CLOCK SLAVE CLOCK SOURCE: WORD CLOCK OUT: This outputs the sampling clock on which the ADA-7000 is operating.
An Example of Connection As an example, we will explain how to connect a Roland VM-7200 mixing processor. * To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections. * This instrument is equipped with balanced (XLR) type input jacks. Wiring diagrams for these jacks are shown below. Make connections after first checking the wiring diagrams of other equipment you intend to connect. fig.
Turning the Power On * Once the connections have been completed (p. 11), turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. * This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally. 1. 2. Turn on the power of the ADA-7000. 3.
