User manual ROLAND DM-20 MANUAL 2

[. . . ] In addition to XLR and TRS phone analog input, the DM-20 is provided with digital input connectors (coaxial and optical) that support 96 kHz sample rate and 24-bit digital audio. Digitally input signals are reproduced faithfully through 24-bit D/A conversion, thus preventing noise or a drop in sound quality. You can use the monitors with a wide variety of equipment and applications through selective use of the analog and digital settings. No part of this publication may be reproduced in any form without the written permission of ROLAND CORPORATION. [. . . ] The unit should be connected to a power supply only of the type described in the operating instructions, or as marked on the unit. Do not force the unit's power-supply cord to share an outlet with an unreasonable number of other devices. Be especially careful when using extension cords--the total power used by all devices you have connected to the extension cord's outlet must never exceed the power rating (watts/amperes) for the extension cord. Excessive loads can cause the insulation on the cord to heat up and eventually melt through. Never climb on top of, nor place heavy objects on the unit. Never handle the power cord or its plugs with wet hands when plugging into, or unplugging from, an outlet or this unit. Before using the unit in a foreign country, consult with your retailer, the nearest Roland/EDIROL Service Center, or an authorized Roland/EDIROL distributor, as listed on the "Information" page. Before moving the unit, disconnect the power plug from the outlet, and pull out all cords from external devices. Before cleaning the unit, turn off the power and unplug the power cord from the outlet. The unit should be located so that its location or position does not interfere with its proper ventilation. Whenever you suspect the possibility of lightning in your area, pull the plug on the power cord out of the outlet. â· During setup and transport, be careful not to damage the vibrating portions (the speaker cone and diaphragm). â· Be sure to place the monitor so that the heat sink on the rear panel is not obstructed. Also, make sure the monitor does not touch any curtains or other fabrics. â· The heat sink performs cooling when the monitor is placed as shown below. Do not place the monitor on its side or upside down. For everyday cleaning wipe the unit with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a cloth impregnated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation. Use a reasonable amount of care when using the unit's buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions. [. . . ] * When the connected digital-signal output device is not powered up, the Digital In indicator does not light up. Turning the control clockwise increases the sound from the speakers. This adjusts the sound quality of the treble range (10 kHz, +/ -3 dB). This adjusts the sound quality of the bass range (80 Hz, +/-3 dB). [. . . ]
