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. Congratulations on your selection of CARVlN products: The Professionals Choice. Your new CX series mixer demonstrates CARVINs 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 CARVINs recognition as The Professionals 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. May you enjoy many years of success and fun with your new CARVIN mixer!

LIST THIS UNIT CONTAINS HIGH VOLTAGE COM- PONENTS INSIDE! REFER SERVICING TO QUALIFIED SERVICE PERSONNEL! CAUTION RISK OF ELECTRIC SHOCK 2 If youre like most new owners, youre probably in a hurry to plug your CX mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and the unit turned off, complete the following procedures: 1. CONNECTING AC POWER TO YOUR MIXER - Check the rear panel to make sure the mixer received uses the proper AC Line Voltage. (USA 120VAC, Europe 240 VAC ...etc.) - Use only a grounded (3 prong) power outlet to prevent a shock hazard. This gives the quietest grounding for your mixer. 2. CONNECTING SPEAKERS (Powered Models Only) - Use the right and left 1/4 speaker jacks on the rear panel which are con- troled by the main level control on the front). The speaker cables should be non-shielded and at least 18 gauge(AWG) wire. For speaker cable runs of over 20 feet 16 gauge wire is recommended.. NOTE: Do not run your speakers through microphone wire, gui- tar cables, or multi-conductor microphone junction boxes or snakes as they are sometimes referred to. This wire is normal- ly shielded and of a very light gauge causing a substantial loss of power and oscillations at high frequencies in the amplifier. All speaker wires must be non-shielded . 3. SpeakerGuardtm and the PROTECT LED - The protect LED comes on along with the output relays in three different pro- tection modes: Shorted speaker outputs, Speaker Impedance below minimum rating, and when the amplifier exceeds maximum operating temperature. - In event the LED comes on turn off the amplifier and Identify and correct any speaker cable or speaker jack shorts and make sure the total speaker Impedance for each output is 4 ohms or greater. Also make sure the fan is not blocked and check that cool air can circulate around the rear of the mixer. 4. CONNECTING INPUTS TO YOUR MIXER - For low level balanced devices such as microphones, plug into the balanced MICinputs using a shielded microphone cable with XLR ends. - For high level unbalanced devices such as Tape Recorders and Keyboards plug into the LINEinput jacks using a shielded cable with 1/4 phone ends. 5. TURNING YOUR MIXER ON - Adjust all channel and master level controls to their off positions (fully counter clockwise). - Adjust all EQ tone controls- the channels Hi, Mid, and Bass and the two master 9 Band Graphic EQs to their center detent position. - Adjust all the Channel PAN controls to their center detent position. - Turn the mixer on by the rear panel power switch and watch for the power LED to come on. Your mixer is now ready to operate. QUICK START UP MAINTENANCE To bring back the new look, your CX mixer can be washed with mild detergent and/ or a warm damp soft cloth. This will remove normal dust and oil from the front and back panels. Never spray cleaners or detergents directly at the unit. The mixers are virtually sealed from outside dust and dirt, but it is recommend- ed to keep the mixer free from dust, dirt, and moisture as much as possible.
