Designed to deliver professional-quality audio, the 12" QSC K12.2 12" 2000W Powered Speaker Kitis a highly flexible, easy to use, 2000W powered portable PA speaker for today's working musicians, singer/songwriters, mobile DJs, and other sound providers. The speaker works in a variety of orientations and configurations for use as a main PA or stage monitor. When used as a main speaker, a pair of K12.2s is well equipped to cover an audience of 300+.

Two inputs (A and B) feature combo XLR-1/4" connectors with input A offering a Mic/Line selection and input B offering Mic/Hi-Z selection, which is designed for connecting high-impedance signals such as guitars and other instruments. Additionally, channel 3 provides a 3.5mm TRS auxiliary input for connecting portable audio devices. With independent mic and line inputs, the K12.2 is a great choice for any singer/songwriter or solo performer with an instrument. You have independent control over mic and instrument levels, while the aux input provides backing tracks or incidental music between sets.

The highly efficient 2000W Class-D amplifier powers the 12" woofer and 1.4" titanium compression driver, which provide full-range audio (50 Hz to 20 kHz) with a sound pressure level powerful enough to ensure the entire audience can hear your performance. QSC's Directivity Matched Transition (DMT) matches the coverage angle of the woofer at the crossover frequency with the horn pattern to ensure a uniform response across the coverage area (75° axisymetric). The Intrinsic Correction techniques ensure a smooth power response resulting in accurate performance in a wide range of acoustic spaces with little or no EQ. The K12.2 includes a power cord.

Related Questions and Answers

Q: 1. Which cable is needed to connect to iPad

A: The QSC K12.2 Two-Way 12" 2000W Powered Portable PA Speaker with Integrated Speaker Processor could receive a hardwired signal from an iPad via its 3.5mm auxiliary input connection. To achieve this, a standard 3.5mm TRS to TRS cable would be required, such as the Pearstone Stereo Mini Male to Stereo Mini Male Cable (Black, 10')(BH #PEMMSA110B). The auxiliary cable would then need to be adapted to Lightning or USB Type-C with one of the 3.5mm adapters offered by Apple (or similar), depending on the connection on the iPad.

Q: 6. this speaker has output line ?

A: Yes. It has a 3 pin XLR line output and a 1/4 line output. Speaking of the 1/4 output, I have checked its electrical connections and as it turned out, it has separated L and R outputs and can drive a stereo TRS connector, although I don't know if the speaker actually drives a mono signal on it or a stereo one. The technical spec sheet has minimal information and doesn't specify it either. However, since it has stereo input, it might be that it drives a stereo output on the 1/4 line output.

Q: 7. There's a IPhone plug connection for a IPhone... Can this plug be used to plug a Android phone into it also? or this is only for a IPhone

A: The iPhone input on the Pyle Pro PPHP1237UB is a standard 1/8 line input and connects with a cable from the headphone jack on any smartphone or small portable mp3 player.

Q: 8. Confused about the output... How much adtional watts can the receiver give to another speaker? Assuming it can work that way.

A: The ouput from the unit is a line level signal. It needs to be connected to another powered speaker, or amplifier.

Q: 9. Do any of the K8.2, K10.2 or even the K12.2 have phantom power going to any of the inputs?

A: The inputs on these speakers do not provide phantom power. For microphones that require phantom power, it will be best to use a separate mixer that can provide power to the mics.

Q: 10. What was the power problem with the K-12?

A: The original K12 was a little under powered, which has been rectified with the K12.2
