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.
