Introduction

The CSM Series of stage monitors is a very low profile, high output wedge speaker that provides the highest output to size ratio of any premium brand. These high performance speakers use a high power, 3" neodymium magnet compression driver, coupled with a 4" voice coil woofer on the CSM12 and CSM15 and a 3" voice coil woofer on the CSM10. The CSM series features a selectable pattern control “shutter” system that by opening the shutter, converts the vertical coverage to an asymmetrical pattern of +45° and -75° relative to the baffle, while maintaining a nominal 50° pattern in the horizontal. As a result, the user is able to limit the amount of sonic HF energy spilling over into the audience, while increasing its upstage coverage angle.

In addition, the CSM Series features integral hardware that provides up to an additional 15° (in 1° increments) of angle to the enclosure as well as a recessed connector pocket that allows the user to dress the cable a full 360° in any direction.

Signal Processing

The CSM Series is designed as a “Best in Class” stage monitor system package. The amazing performance of the CSM models is a result of extensive and sophisticated application of digital signal processing. The algorithms have been developed using QSC processing products and can not be readily replicated on other DSP platforms. In order to enjoy all the performance that your QSC CSM speakers can deliver, it is important to use the correct QSC signal processors loaded with the appropriate processing settings. Visit the Support section of the QSC website (www.qscaudio.com) and navigate to “Technical Support” - “Software Downloads” to obtain the correct settings for your monitor model, QSC processor and application. Note that application specific settings for full-range, bi-amp, stage monitor and utility applications are available.

QSC will, from time to time introduce new digital signal processing platforms so check the “CSM Series” section of the QSC website for the latest processor recommendations.

Power

In order to take full advantage of CSM Series capabilities abundant and clean amplifier power is required. Recommended amplifiers and power levels:

CSM10

•LF amplifier: QSC PL340 or other amplifier capable of at least 800 W @ 8Ω; 1250 W @ 4Ω & 2000 W @ 2Ω.

•HF amplifier: QSC PL325 or other amplifier capable of at least 500 W @ 8Ω; 850 W @ 4Ω & 1250 W @ 2Ω.

CSM12 and CSM15

•LF amplifier: QSC PL380 or other amplifier capable of at least 1500 W @ 8Ω; 2500 W @ 4Ω & 4000 W @ 2Ω.

•HF amplifier: QSC PL325 or other amplifier capable of at least 500 W @ 8Ω; 850 W @ 4Ω & 1250 W @ 2Ω.
