1. Keep this manual for future reference. 

2. Heed all warnings. 

3. Follow all instructions. 

4. Do not use this unit near water. Do not spill water or other liquids into or on the unit. Do not

operate the EPAK 2500R while wet or standing in liquid. 

5. Clean only with dry cloth. 

6. Do not block the air intake or exhaust ports. Install the unit in accordance with the

instructions. 

7. Do not operate the EPAK 2500R near heat producing devices such as radiators, heat registers,

stoves or other apparatus that produce heat. 

8. Always operate the unit with the chassis ground wire connected to the electrical safety earth.

Do not defeat the safety purpose of a grounding-type plug. A grounding type plug has two
pins and a third grounding prong. The third prong is provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 

9. Connect only to AC power outlets rated 115-250V, 50-60Hz. 

10. Do not use this EPAK 2500R if the power cable is broken or frayed. Protect the power cable

from being walked upon or pinched particularly at the plugs and the point where it exits from
the apparatus. 

11. Only use accessories specified by the manufacturer. 

12. The unit is intended to be used in a 19” rack. Follow the mounting instructions. When a rack

on wheels is used, use caution when moving the loaded rack to avoid injury from tipping over. 

13. Unplug this apparatus during lightning storms or when unused for long periods of time. 

14. Do not connect an EPAK 2500R output in parallel or series with any other EPAK 2500R’s

output. Do not connect the EPAK 2500R output to any other voltage source, such as battery,
mains source, or power supply, regardless of whether the EPAK 2500R is turned on or off. 

15. Do not run the output of any EPAK 2500R back into another channel's input. 

16. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has

been damaged in any way such as: 

• Power-supply cord or plug is damaged 

• Liquid has been spilled into the unit 

• An object has fallen into the unit 

• The unit has been exposed to rain or moisture 

• The unit does not operate normally 

• The unit was dropped or the enclosure is damaged 

17. Do not remove top or bottom covers. Removal of the cover will expose hazardous voltages.

There are no serviceable parts inside and removal may void the warranty. 

18. An experienced user shall always supervise this professional audio equipment, especially if

inexperienced adults or minors are using the equipment.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER.
