I had a question on how the amp can hook up...at least i think that is what is was. Specifications are subject to change without notice. "convert those from "balanced / professional line level" to "unbalanced / consumer line level" 2 Calculated SPL at 1 m, speaker operating at rated RMS power with pink noise within specified frequency range 3 Maximum input power tested in accordance with IEC 268-5 recommendations, 50 Hz – 20 kHz band limiting, 6 dB signal crest factor. 2. Now you can hook up as many subs as you want. It is only 14" (355.6mm) wide by 26" (660.4mm) tall, so it fits into some very tight spaces – especially when laid on its side and slid under a riser platform stage. The CP Series loudspeakers are equipped with a universal power supply that can use input AC power voltages ranging from 100 – 240 VAC at 50 – 60 Hz. You’ll run your volume much higher to get the volume. When people put a sub left and right and send the sub the L or R out only, you are denying yourself the subs full potential because of decreased input voltage. Most powered speakers have balanced XLR or TRS jacks, or both. In some cases, you may find an RCA connector marked LFE (Low Frequency Effects) on a receiver or pre-amp; hooking up the "LFE" jacks usually only sends bass special effects of a 5.1- encoded movie to the subwoofer. It’s possible (though rare) that your mixer only has unbalanced outputs. The second option is the KW181 subwoofer. Yes, you can crank the sub up more on the amp panel, but proper gain staging goes a … These are problematic in long runs, and are more susceptible to picking up noise and interference.

The level controls on your mixer may now be brought up. 1 All frequency ranges specified refer to measured free field response. Replacements are available from QSC. If the QSC- supplied cord is lost or damaged, a standard 18-gauge IEC power cord may be used. The mixer has no further outputs to connect the subwoofer. The subwoofer has unbalanced inputs, which seems to be at "Consumer Line-Level; So now we need to do the following: Take the mix-output from both Alto TS210's, to feed the subwoofer. Almost all current mixers have balanced output jacks, again with XLR, TRS, or both connectors. If the QSC-supplied cord is lost or damaged, a standard 18-gauge IEC power cord may be used. Connect the AC Power cord to the facility’s AC outlet. The other benefit of this connection is if you had more than two subwoofers, three or four let’s say, you can keep chaining them in this manner, going from the input on one to its output to the input on the next subwoofer out of its output to the input on the following subwoofer and so on.
