Unpacking
Please take a few minutes to read this manual to familiarize yourself with important information regarding installation, product features, and operation.
As with most electronic devices, ORIGINAL PACKAGING (OR EQUAL) IS REQUIRED in the unlikely event that the product needs to be returned for servicing.
Short Form Instructions
1. Do not connect the AC power until step 6. The ac mains POWER switch should be in the OFF position.
2. Adjust both of the LEVEL controls to the fully attenuated position (turn fully counter-clockwise).
3. Connect an appropriate line level input signal to either the balanced XLR or the balanced 1/4” TRS (Tip­Ring-Sleeve) connector marked INPUTS.
4. Move the MODE selector to the desired position. The Stereo position is the most common.
5. Connect the OUTPUTS to the speaker load according to the mode of operation determined in the previous step.
6. With the ac mains POWER switch in the OFF position, plug in the supplied Universal AC power cord to the product and connect to an appropriate AC source.
7. Depress the ac mains POWER switch to the ON position. The indicator within the power switch will illuminate.
8. The product is ready for operation. Slowly increase the LEVEL control to the desired operating level. Avoid illuminating the PEAK indicator and do not apply too much power to the speakers.
9. Operate the product and the system in a manner which DOES NOT illuminate the PEAK warning indicator.

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.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. 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 or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
