11System ConfigurationDecide what kind of system to form. Determine the num-ber of the external devices, the connection form, and themode (p. 14 Unit Modes and Signal Flow).dConnectionsConnect the components to the unit.dSettingsConfigure the following settings:• Modes (pp. 14 to 17)• Input line assignment (if using the SUB OUT jack) (p.18)• Output line assignment to MULTI IN/LINE IN.(p. 19)dSticking a Label (p. 26)Stick the supplied label on each component.dAdjusting the Input and Output Levels (pp. 29 to 31)Adjust the input and output levels with the knobs on thefront panel.dAttaching/detaching the acrylic cover (p. 28)Attach the acrylic cover on the unit front panel to preventwrong operation.INSTALLATION■ Work Flow ■ Before InstallationCaution:Contact your dealer for installing the unit.Be sure to toggle the power off and unplug the unit fromthe receptacle before installation. Follow the safetyinstructions.● Power ConnectionConnect the power cord by any of the following methods,making sure to provide a breaking device in each case.(1) Connect the power cord to the power control unit.(2) Install the unit near a receptacle and connect the powercord to the receptacle via a breaking device. Thebreaking device should be installed near an operator.(3) Connect the power cord to a circuit breaker in a panelboard that has a contact distance of 3.0 mm or more.Use a circuit breaker that will interrupt each circuit ofthe main power supply (except a ground-protectiveconductor).● Installation Place• Install the unit out of direct sunlight and away from out-lets of heated air. Installation in a humid, dusty or shakyplace may cause trouble.• Keep a distance between this unit and a transformer,dimmer, image device, CRT monitor, etc. as much aspossible. Failure to do this may cause induction noise.● Rack MountingKeep the temperature in the rack below 45 °C . Failure todo this may cause damage to internal components.● Grounding the UnitGround the unit by the grounding terminal at the rear side.If the devices are connected in unbalanced connections,synchronize each grounding potential as follows:• Synchronize the power supply phases.• Synchronize the power supply lines.• Connect each device's grounding terminal or chassiswith a thick grounding wire of each device.Failure to do this may cause induction noise.Note: If the unit is placed more than 10 m away fromother external devices, grounding the unit near an unbal-anced external device is recommended.● Condenser Microphone• When using a condenser microphone, connect it to anexternal device.• Do not connect external devices supplying phantompower, as it may damage the unit.
