Otherwise, you will need to use equivalent packaging materials. • Use a cable from Roland to make the connection. If using some other make of connection cable, please note the following precautions. • Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable. • Howling could be produced depending on the location of microphones relative to speakers. This can be remedied by: •Changing the orientation of the microphone. •Relocating microphone at a greater distance from speakers. •Lowering volume levels. 5 f ■pi| • I « A «I .

' ) { Rear Power Indicator Lights when power is on. - Digital In Indicator This lights up when output is received from a connected digital device or during standby. Connect the digital-signal output device, set the "Input Select switch" to DIGITAL INPUT, and set the "Digital Input select switch" according to the connector to which the device is attached (Coaxial or Optical). * When the connected digital-signal output device is not powered up, the Digital In indicator does not light up. 10 6 8 9 a I a-AMP MONITOR nCfsnd SfS9.£ Power cord' 3 1 1 Analog Input XLR/TRS Phone Input Connector (Analog Input) This is for connecting XLR or TRS phone plugs. XLR type TRS Phone type phone type (Unbalanced) (Balanced) Both balanced and unbalanced connections are possible. The pin assignment for the connector is as shown below. Before making any connections, make sure that this pin assignment is compatible with that of all your other devices. GND(SLEEVE) 1 :GND I 3:COLD HOT(TIP)- 6 Names of Things and What They Do 2 Digital Input Coaxial Input Connector (Digital Input) This is the digital input connector for coaxial cable. It cannot be used for input of analog audio signals (no sound is produced). Optical Input Connector (Digital Input) This is the digital input connector for optic-fiber cable. Use commercially available optical cable for audio equipment to make the connection. Optical-connector Protective Cap After removing the protective cap, put in a safe place so that it doesn't get lost. When not using the optical connector, attach the cap to keep the connector safe. - When using the optical connector, be sure that the cap you removed is placed out of the reach of children. If a child has accidentally swallowed a cap, see a doctor immediately. Digital Input Select Switch This switch selects Optical or Coaxial. Select the connector used for the input signal. Assign Switch This switch selects the stereo position of the digital signal. It selects Right, L+R, or Left when using two DS-90A monitors for stereo sound (with digital signals). Choose the setting appropriate for your setup. With the DS-90A, there is no difference between L and R. When using the digital input connectors of two DS-90A monitors for stereo sound, the digital signal can be input to either L or R. 3 Input Select Switch Used to select Digital Input or Analog Input. Select the connector used for the input signal. 4 Thru (Digital Out) Connector When connecting multiple DS-90A monitors with digital signals, this connector is used for output to the second DS-90A. Refer to "Connection Examples" (P. 8,9). 5 Input Level Control This adjusts the input level. Turning the control clockwise increases the sound from the speakers. 6 LF Trim Control This adjusts the sound quality of the bass range (60 Hz, +/-3 dB). 7 HF Trim Control This adjusts the sound quality of the treble range (10 kHz, +/-3 dB). The LF Trim and HF Trim controls on the DS-90A are designed to correct the sound quality of the sonic field. Use these to make fine adjustments to match the usage conditions. 8 Power Switch This switch turns the power on/off. Before turning the power on or off, yon must lower the volume of this unit and your connected device etc. 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. 9 AC Inlet Connect the included Power cord here. Plug it firmly in, so that the cable does not accidentally become disconnected. 10 Heat Sink This is a heat-radiating plate that dissipates excess heat. 7 Connection Examples Important Notes on Precautions When Connecting Placement and Turning on the Power • During setup and transport, be careful not to damage the • To prevent malfunction and/or damage to speakers or vibrating portions (the speaker cone and diaphragm). other devices, always turn down the volume, and turn off the power on all devices before makin...
