RECEIVING INSPECTION

INSPECT YOUR CX MIXER FOR ANY DAMAGE which may have occurred during shipping. If any damage is found, notify the shipping company and call CARVIN immediately.

SAVE THE CARTON & ALL PACKING MATERIALS. If you have to reship your mixer, always use the original carton and packing material. This will provide the best possible protection for the mixer during shipment. CARVIN and the shipping company are not liable for any damage caused by improper packing.

SAVE YOUR INVOICE. It will be required for warranty servicing of your unit. Always check the invoice against the items you have received.

SHIPMENT SHORTAGE. If you find some items missing, it may be that they were shipped separately. Please allow several days for the rest of your order to arrive before inquiring. If you determine (after allowing an appropriate amount of time) you have not received all the items you ordered, please call CARVIN.

FOR THE NEW OWNER

Congratulations on your selection of CARVlN products: “The Professional’s Choice.” Your new CX series mixer demonstrates CARVIN’s commitment to producing the highest quality and most sophisticated engineering in the audio industry today. Its wide acceptance and use by industry professionals illustrates the basis for CARVIN’s recognition as “The Professional’s Choice.”

The CX series mixers were designed to be a professional quality mixer in a com- packed package. The desire was to pack as many professional features into the smallest package we could, without sacrificing the quality of any one of the fea- tures or the mixer. The CX1252 includes a full function 12 channel stereo mixer, two nine band graphic equalizers, a 128 preset digital signal effects processor, and a 500 Watt stereo power amplifier capable of 250 Watts a side into 4 ohms. The CX842 is an 8 channel stereo mixer with a 400 Watt power amplifier. The CX842 has all the features of the CX1252 including the two nine band graphic equalizers and the effects processor. Each CX series mixer is the size of a 5 space rackmount unit surrounded by a 3/4” poplar plywood cabinet covered with Duratuff carpeting making the CX mixer road worthy and ready for a show any- where.

If you would like to comment on any features or the performance of your new mixer, please feel free to contact us. Comments from our customers have helped us to improve and further develop our products and our business.
