CSM Series

The CSM Series are system packages comprising stage monitor loudspeakers, proprietary digital signal processing, and high power amplifiers in a tightly integrated design that offers the highest output-to-size ratio of any premium brand stage monitor on the market to date. 

Combining elegant industrial design with state-of-the-art driver and waveguide technology, these very-low-profile wedges embody all the contemporary desired attributes asked for by today's most demanding monitor engineers. This level of performance is only possible by the specific application of very sophisticated and carefully tailored QSC digital signal processing, combined with exact high power amplification. We believe that the results speak for themselves. 

The processing algorithms developed for CSM go way beyond simple crossovers and equalization. Processing has been designed to allow the monitors to play at extremely high levels while eliminating the artifacts that could cause a system to exhibit harshness, breakup or lack of clarity. You will be astonished at how well a vocal can sit on top of an instrument mix, even when the system is pushed to its limits.

In order to achieve this feat, the Concert Stage Monitors require abundant, clean power resulting in enormous dynamic headroom. PowerLight 3 Series amplifiers fill this bill perfectly. 

CSM monitors utilize a selectable pattern control "shutter" system that enables the user to limit the amount of sonic energy spilling over into the audience, while increasing its upstage coverage angle. By opening the shutter, the vertical coverage is converted to an asymmetrical pattern of +45° and -75° off axis, while maintaining a nominal 50° pattern in the horizontal.

In addition to the generous upstage coverage of the CSM waveguide - special integral hardware provides up to an additional 15° (in 1° increments) of angle to the enclosure to gain a more extreme upstage coverage. 

One of the problematic conditions that have long plagued most stage monitor designs is the location of the input and output speaker connections. If they are located on the sides, they can often be in the way when placing multiple monitors side by side. If they get mounted on the down-stage side (facing the audience), they tend to become unsightly and cluttered in view from the audience. If they are placed on the up-stage side (facing the musician), they tend to wind up under the performers feet and often get damaged or broken during performances. 

QSC CSM monitors utilize a unique recessed connector pocket mounted on the bottom side of the enclosure, that with the use of its four corner rubber feet, enable the user to dress the cables in any direction needed (360°), while fully protecting the cable end connectors from damage or sight issues.
