User manual PEAVEY IMPULSE 100P

[. . . ] Impulse® 100P Operation Manual For more information on other great Peavey products, go to your local Peavey dealer or online at www. peavey. com Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: Risk of electrical shock -- DO NOT OPEN!CAUTION: To reduce the risk of electric shock, do not remove cover. [. . . ] In that case, reduce the mixer output level, and turn up the volume control on the Impulse 100P. The amplifiers in the Impulse 100P are equipped with DDTTM, with an LED indicator to show DDT has engaged. If the sound seems heavily compressed, check this indicator, and if it is indicating more than occasionally, then the drive level from the mixer (or the volume control on the Impulse 100P) needs to be reduced. When first turning on the sound system, turn on all upstream electronics first, then the Impulse 100P with its volume control fully CCW (all the way down). Begin checking levels with the mixer output level controls all the way down, and bring them up slowly with the Impulse 100P volume control set to the desired setting (1/2 way up recommended to start). USE OF MULTIPLE IMPULSE 100Ps (or other Impulse series powered products) The provision of multiple parallel inputs allows the inputs of the Impulse 100P to be "daisy-chained" from one to the other. Run the first cable from the mixer to the first Impulse 100P, then hook a cable from one of the first Impulse 100P's inputs to the second Impulse 100P's input. This can be continued for several units, depending on how long the cables are, and the total capacitance of all the cables. With a low source impedance, such as a typical mixer output, and typical balanced cables, 2 or 3 Impulse 100Ps can be daisy-chained from one output using 30' or 40' cables without obvious loss of high frequencies. The Loop-Thru jacks (7), can also be used to connect one other Impulse 100P or one other Impulse 1000 series powered unit, and conveniently control volume from just one of the units. Connect a well shielded 1/4" to 1/4" phone plug patch cord from the Loop Out jack one unit that has the input connected to the signal source, and then plug this cable into the other unit's Loop In jack. The volume control of the first unit now controls the volume for both identically. Do not connect cables to the jacks while the units are ON and the Volume is turned up!APPLICATIONS The Impulse 100P has a variety of applications such as sound reinforcement, public address, side fill system, or musical playback. With the optional monitor stand kit, the Impulse 100P makes an excellent stage monitor. A typical signal source for the line-level inputs (5) of the Impulse 100P would be a sound reinforcement mixing console (mixer), or the output from a CD player, Minidisc player, or tape deck. 8 TROUBLESHOOTING No Output at All First, make sure the unit has AC power and is turned on. If so, the Power LED (4) should be illuminated. If it is not, check that the On-Off switch (3) is in the "On" position, check the IEC power cord connection (2), making sure it is fully engaged and seated. Make sure the AC line cord is plugged into a working AC outlet, and last, check the fuse (2) {see the REAR PANEL/Fuse section for safety instructions}. Then, make sure that the inputs of the Impulse® 100P are getting a signal by plugging the cable run into the Impulse 100P's inputs to some other device capable of determining this (for example, a power amp and speaker). If there is still no output, then be sure the volume control has been turned up to a reasonable level (1/3 to 1/2 way). Has the Impulse 100P been in direct sunlight or excessive heat?
