Important Safety Instructions

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

15. Damage Requiring Service Unplug the apparatus from the wall outlet and refer servicing to qualified service personnel under the following conditions:

A. When the power-supply cord or plug is dam-

aged,

B. If liquid has been spilled, or objects have fallen

into the apparatus,

C. If the apparatus has been exposed to rain or

water,

D. If the apparatus does not operate normally by

following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the apparatus to its normal operation,

E. If the apparatus has been dropped or damaged in

any way, and

F. When the apparatus exhibits a distinct change in

performance this indicates a need for service.

16. Object and Liquid Entry

Never push objects of any kind into the apparatus through openings as they may touch dangerous voltage points or short-out parts that could result in a fire or electric shock. The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases shall be placed on the apparatus. Don’t put candles or other burning objects on top of this unit.

17. Batteries

Always consider the environmental issues and follow local regulations when disposing of batteries.

18. If you install the apparatus in a built-in installation,

such as a bookcase or rack, ensure that there is adequate ventilation. Leave 20 cm (8") of free space at the top and sides

and 10 cm (4") at the rear. The rear edge of the shelf or board above the apparatus shall be set 10 cm (4") away from the rear panel or wall, creating a fluelike gap for warm air to escape.

Precautions

1. Recording Copyright—Unless it’s for personal use only, recording copyrighted material is illegal without the permission of the copyright holder.

2. AC Fuse—The AC fuse inside the unit is not userserviceable. If you cannot turn on the unit, contact the dealer from whom you purchased this unit.

3. Care—Occasionally you should dust the unit all over with a soft cloth. For stubborn stains, use a soft cloth dampened with a weak solution of mild detergent and water. Dry the unit immediately afterwards with a clean cloth. Don’t use abrasive cloths, thinners, alcohol, or other chemical solvents, because they may damage the finish or remove the panel lettering.

4. Power WARNING

BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME, READ THE FOLLOWING SECTION CAREFULLY. AC outlet voltages vary from country to country. Make sure that the voltage in your area meets the voltage requirements printed on the unit’s rear panel (e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).

The power cord plug is used to disconnect this unit from the AC power source. Make sure that the plug is readily operable (easily accessible) at all times.

Pressing the [On/Standby] button to select Standby mode does not fully shutdown the unit. If you do not intend to use the unit for an extended period, remove the power cord from the AC outlet.

5. Preventing Hearing Loss Caution

Excessive sound pressure from earphones and headphones can cause hearing loss.

6. Batteries and Heat Exposure War nin g

Batteries (battery pack or batteries installed) shall not be exposed to excessive heat as sunshine, fire or the like.

7. Never Touch this Unit with Wet Hands—Never handle this unit or its power cord while your hands are wet or damp. If water or any other liquid gets inside this unit, have it checked by the dealer from whom you purchased this unit.

Amplifier Precautions

Before using the DTA-70.1 power amplifier, be sure to read the page above entitled Important Safety Instructions and this page of Amplifier Precautions.

Ventilation

While using the DTA-70.1, the internal temperature will fairly rise. Excessive temperature rise may affect the amplifier performance. To prevent damage from occurring due to high internal temperatures, it is vital to have proper ventilation and passage of air to carry out the heat and keep the internal temperature within acceptable ranges.

Caution

• Do not place the DTA-70.1 inside cabinets or closets where there is poor passage of air and ventilation.

• Do not place the DTA-70.1 near external heat sources such as heaters or hot air ducts.

• Do not place other components or object on top of or under the DTA-70.1.

• The cover of the DTA-70.1 contains ventilation holes to allow the passage of air. Do not cover or block these holes in any way.

If you are planning to place it within a cabinet, either open holes in the rear panel of the cabinet to improve ventilation or use a fan to force air circulation.

As a general rule, if during idling the cover is too hot to touch, then ventilation needs to be improved.

Installation location and space

Make sure that the floor or cabinet or rack where it will be located is strong enough to support its weight. You will also need to leave enough space behind the DTA-70.1 to allow room for the power cord and other cables for connecting system components. A minimum of four inches is required behind the DTA-70.1 to allow room for the cables and cords without excessively bending them. Do not place the DTA-70.1 near TV or radio. This may cause noise or instable video on radio or TV respectively.

Power cord

Do not use a power cord other than the one supplied with the DTA-70.1. The power cord supplied is designed for use with the DTA-70.1 and should not be used with any other device.

Be sure to only use wall sockets that properly fit the plug of the power cord. If the socket does not match the plug of the power cord, you will need to prepare an adapter. Always use an adapter that is properly certified for this application.

Speakers

Connected speakers should have an impedance of 4 ohms or greater.

If speakers with an impedance of less than 4 ohms are connected, it may damage the DTA-70.1.

Care

From time to time you should wipe the front and rear panels and the cabinet with a soft cloth. For heavier dirt, dampen a soft cloth in a weak solution of mild detergent and water, wring it out dry, and wipe off the dirt. Following this, dry immediately with a clean cloth. Do not use rough material, thinners, alcohol or other Chemical solvents or cloths since these could damage the finish or remove the panel lettering.

Whenever performing maintenance on the DTA-70.1, any of its supplied accessories, or any device connected to it, do not use solvents or cleaners of any kind that are inflammable or combustible. When you clean the input/output terminals on the rear panel, do not use contact restorer. Doing so may cause resin deterioration.

Other

Below is a list of actions that you should never perform.

• Do not use the DTA-70.1 as a broadcast system or musical instrument amplifier.

• Never use a generator, DC/AC converter, AC/AC converter, or transformer to supply power for the DTA-70.1.

• Never perform a “thumb test” (checking whether current is reaching the lead wire on the hot end of the input by touching it with your fingers) on the ends of the input jacks or input cables. Doing so may damage the speakers.

• Do not short across the output terminals or across the output terminals and rear panel.

• Never remove the cover of the DTA-70.1.

• Do not install the DTA-70.1 in a location within the reach of small children.

Lightning storms

During lightning storm, never touch the power cord, plug or cover of the DTA-70.1, and any devices connected to the DTA-70.1.

Power

WARNING:

BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME, READ THE FOLLOWING SECTION CAREFULLY.

AC outlet voltages vary from country to country. Make sure that the voltage in your area meets the voltage requirements printed on the unit’s rear panel (e.g., AC 220-240 V, 50/60 Hz or AC 120 V, 60 Hz).
