This amplifier is compatible with all types of public addressing systems, live concerts, stage shows, indoor and outdoor programs, and religious programs. It features 7 microphone inputs and 2 auxiliary inputs, with individual volume controls and tone controls for bass and treble. The CKA-400 also includes a built-in digital player with USB, SD card, and Bluetooth connectivity for versatile audio playback. For advanced audio setups, it offers pre-amplifier and line output for connecting to a booster amplifier and recording programs. A resettable circuit breaker protects against overload and short circuits, and it has an instant transfer to DC power from a car battery in case of AC power failure. A box speaker/driver unit selector switch is included to optimize sound output based on the connected speakers, with the bass boost being defeated in the driver unit position for safer operation of driver units.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":57,"@type":76,"position":81},"https://docshare.wps.com/document/general/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/cka-400-pa-mixer-amplifier/203775/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/cka-400-pa-mixer-amplifier/203775.png","ImageObject",300,407,{"name":92,"@type":93},"Maeve","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-07","2026-09-04",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What are the input channels available on the CKA-400 amplifier?","Question",{"text":112,"@type":113},"The CKA-400 features 7 microphone inputs and 2 auxiliary inputs, along with one Line input and a built-in digital player with USB, SD card, and Bluetooth.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What are the power output specifications of the CKA-400?",{"text":117,"@type":113},"The CKA-400 delivers 450W RMS Max power output and 400W RMS at 10% THD.
