Read instructions: Retain these safety and operating instructions for future reference. Heed all

warnings printed here and on the equipment. Follow operating instructions printed in this user guide.

Do not open: There are no user serviceable parts inside. Refer any service work to qualified technical personnel

only.

Power sources: Only connect unit to mains power of type marked on rear panel. Power source must provide a

good ground connection.

Power cord: Use the power cord with sealed mains plug appropriate for your local mains supply as provided with

the equipment. If the provided plug does not fit into your outlet consult your service agent. Route the power cord

so that it is not likely to be walked on, stretched or pinched by items placed upon or against.

Grounding: Do not defeat the grounding and polarization means of the power cord plug. Do not remove or tamper

with the ground connection on the power cord.

Ventilation: Do not obstruct the ventilation slots or position the unit where the air required for ventilation is

impeded. If the unit is to be operated in a rack, case or other furniture ensure that it is constructed to allow

adequate ventilation.

Moisture: To reduce the risk of fire or electrical shock do not expose the unit to rain, moisture, or use in damp or

wet conditions. Do not place a container of liquid on it, which may spill into any openings.

Heat: Do not locate the unit in a place close to excessive heat or direct sunlight, as this could be a fire hazard.

Locate the unit away from any equipment, which produces heat such as: power supplies, power amplifiers and

heaters.

Environment: Protect from excessive dirt, dust, heat, and vibration when operating and storing. Avoid tobacco

ash, drink spillage and smoke, especially that associated with smoke machines.

Handling: To prevent damage to the controls and cosmetics avoid rough handling and excessive vibration.

Protect the controls from damage during transit. Use adequate padding if you need to ship the unit. To avoid injury

to yourself or damage to the equipment take care when lifting, moving or carrying the unit.

Servicing: Switch off equipment and unplug the power cord immediately if it is exposed to moisture, spilled liquid,

objects fallen into opening, the power cord or plug becomes damaged during a lightning storm, or if smoke odor or

noise is noted. Refer servicing to qualified technical personnel only.

Installation: Install the unit in accordance with the instruction printed in the user manual.

The ART HVA Series 1 and 4 are class-D installation amplifiers. They are suitable for both

70/100V line installations (selectable through dip-switches). Each channel has its own

gain control and LED indicators (signal, clip and protection). The input and output connections

are made through Euroblock connectors. The amplifiers are a 1U rack 19-inch size is very

appropriate for many types of installations, taking advantage of its multichannel design.
