User manual KLIPSCH KA-1000-THX

[. . . ] DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. PROTECT the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. USE only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. [. . . ] REAR PANEL INPUTS AND OUTPUTS / CONNECTIONS AND SETUP Make all connections with the power turned "OFF" on both the subwoofer amplifier and your receiver or preamplifier!Line Level Input The Line Level input consists of a pair of gold-plated RCA phono jacks. (Use a shielded, high quality subwoofer interconnect cable of appropriate length with RCA plugs on each end. ) This input can function as either a Line Level input or an LFE Input, depending on the position of the THX On/Off switch. Line Level Output The Line Level output consists of a pair of gold-plated RCA phono jacks. this output is an unfiltered passthru of the Line Level input signal. It can be used to connect to a second KA-1000-THX amplifier or to connect back to your electronics if needed. This is a simple connection that is easy to use, secure and foolproof. You simply align the tab on the connector with the slot on the output jack, fully insert the connector, turn it clockwise and the collar locks into place (Figure 1). To remove it, pull back on the collar and while holding it back, turn it counterclockwise and pull it out. If you are using two KW-120-THX subwoofers, connect the second one in the same fashion to the KA-1000-THX's second output jack. (A single, 20-foot length, THX Ultra certified subwoofer speaker cable is provided with each KW-120-THX subwoofer enclosure. Crossover Adjustment ­ With the THX switch in the "On" position as suggested for this type of setup, the crossover control will not function. Your receiver or processor will perform the crossover functions for the subwoofer in this situation. When using either the KL-650-THX or KL-525-THX as your front speakers, select the 80Hz (THX) crossover frequency. Level Control ­ With the THX switch in the "On" position as suggested for this type of setup, the level control will not function. Your receiver or processor will perform the volume level functions for the subwoofer in this situation. Phase Control ­ In some installations the setting of the Phase control may not make much difference, whereas in others it may be necessary to go back and forth between the Phase and Level controls for a while in order to get the very best blend with the main speakers. Since each control setting (including the one for crossover frequency in the receiver or processor) affects the optimum settings for the others, it often takes a while to get everything dialed in just right. Start with the Phase control at 0° and play a recording with a prominent, repeating bass line in your listening position. Repeat this process with the control in the 90° and 180° positions. Insert the line cord into this jack, set the Master Power switch to "Off", then insert the power cord into an appropriate AC receptacle. [. . . ] If you don't have their specifications, take an educated guess based on the size of the speakers. A large speaker will usually work down to lower frequencies than a small speaker. So for a large floorstanding loudspeaker, you might start with the Crossover frequency set all the way down to 40Hz, whereas for very small satellite speakers you might want to turn it all the way up to 120Hz. typical bookshelf speakers would tend to be in the 50Hz to 80Hz range.
