QSC K.2 Series™ Firmware Update necessary for all customers:
When played at excessive levels with audible distortion, K10.2 models may experience a critical low frequency driver failure with no amplifier protection to alert the user. The unit may also overheat, with the potential to damage the rest of the loudspeaker. This issue is remedied by updating the firmware from version 1.0.8 or 1.1.0 to version 1.2.0. With this update, if a failure occurs the amplifier will power off voltage to both drivers and allow the user to complete a listening test to determine if the loudspeaker requires service.
Owners of K10.2 loudspeakers MUST check their firmware version and, if necessary, install the firmware update. Owners of K12.2 and K8.2 will also benefit from amplifier protection improvements in the new firmware, and are encouraged to update their loudspeakers as well.
This firmware version 1.2.0 also includes the required firmware update for QSC K.2 Series™ loudspeakers in 220-240 V regions. This update is user-installable and takes only a few minutes to complete.
QSC remains committed to quality, reliability, and the satisfaction of our customers. Please assist us in this regard by ensuring your K.2 product is running the latest firmware.
