User manual PEAVEY IMPACT FIRENZA

[. . . ] Before using this appliance, read the operating guide for further warnings. WARNING: When using electrical products, basic cautions should always be followed, including the following: Do not use this apparatus near water. Do not block any of the ventilation openings. install in accordance with manufacturer's instructions. [. . . ] Begin checking levels with the mixer output level controls all the way down, and bring them up slowly with the Impulse 1015P volume control set to the desired setting (halfway up recommended to start). Be sure to keep the mic away from the front of the speaker after switching the mic input ON and during level setting of the microphone, as very loud feedback will occur!The recommended placement of the person using the microphone is to the side and slightly to the rear of the Impulse 1015P, not out in front of the speaker system. When not using the mic input, be sure to switch off the mic (7) for the lowest noise and hum pickup. Set the microphone level using the Volume control (6), the sound source may be louder during the actual presentation, and there is also the possibility that the microphone may be brought closer to the front of the speaker later on. For best results, the microphone should be held close to the user mouth instead of a foot or more away. Do not "eat" the mic that is, do not put your lips right on the mic, as this can often result in a boomy sound. The best results are obtained when the mic is approximately 2-3" away from the mouth. When using the mic input (8) and the regular inputs (5) for simultaneous music, speech or singing, the volume for the mic should be set first using the Level control (6) as described above. The level fed to the regular inputs should be set to the desired level and matched to the microphone levels using the source Level Control or mixer. USE OF MULTIPLE IMPACT FIRENZAs (or other Impulse series powered products) Multiple parallel inputs allow the Impulse 1015P to be "daisy-chained" from one to anther. Even though the Impulse 1015P is an extremely powerful and high output unit, it does ultimately have limits, and it may require additional powered units (or a sub-woofer) to provide enough sound output or coverage. In this case, try turning the mixer levels down a little to see if that clears things up. After checking everything listed to check in this manual and anything else you can think of to check safely, if the system still exhibits problems, carefully note all conditions and check with your Peavey dealer for advice. CARE AND MAINTENANCE Your Impulse 1015P is a sturdy, durable product that will provide years of reliable use if cared for properly. Use common sense and read the safety warnings to avoid hazardous operating conditions. Tightening the bolts on the rear panel may require that the front speaker grille be removed, and then the woofer, and reaching in from the front to restrain the nuts from spinning. The unit must be disconnected from the AC power source before any work is done on it. Sunlight/Heat Avoid prolonged exposure to direct sunlight, as this may cause the unit to overheat and thermally shut off. Excessively hot operating conditions can also cause a thermal shut down. Do not store in extremely hot or cold conditions or extremely high humidity. Always allow unit to come to room temperature before use.
