Reference Front & Rear Panels The following applies to both the MW12CX and MW12C. In cases where different features need to be described for each model, the MW12CX feature will be described first, followed by the MW12C feature in brackets: MW12CX (MW12C). Channel Control Section Channels 1 to 4 (Monaural) Channels 5/6 and 7/8 (Stereo) Channels 9/10 and 11/12 (Stereo) 1 1 4 2 3 3 5 6 6 7 7 8 9 9 0 0 0 A A A B B B C C C D D D 1 MIC Input Jacks (CHs 1 to 4, 5/6, 7/8) These are balanced XLR-type microphone input jacks (1:Ground; 2:Hot; 3:Cold). 2 LINE Input Jacks (CHs 1 to 4) These are balanced TRS phone-jack line inputs (T:Hot; R:Cold; S:Ground). You can connect either balanced or unbalanced phone plugs to these jacks. 3 LINE Input Jacks (CHs 5/6 to 11/12) These are unbalanced phone-jack stereo line inputs. 4 LINE Input Jacks (CHs 9/10, 11/12) These are unbalanced stereo RCA pin jacks. NOTE Where an input channel provides both a MIC input jack and a LINE input jack, or a LINE input jack and an RCA pin jack, you can use either jack but not both at the same time. Please connect to only one jack on each channel. 5 INSERT Jacks (CHs 1 to 4) Each of these jacks provides an insert point between the equalizer and fader of the corresponding monaural input channel (CHs 1 to 4). The INSERT jacks are ideal for connecting devices such as graphic equalizers, compressors, or noise filters into the corresponding channels. These are TRS (tip, ring, sleeve) phone jacks that carry both the send and return signal (tip = send/out; ring = return/in; sleeve = ground). NOTE Patching external devices via an INSERT jack requires a special insert cable such as illustrated below (insert cable sold separately). To the input jack of the external processor To the INSERT I/O jack Tip: OUT E E E F F F G G G H H H I I I Sleeve (Ground) Ring: IN Tip: OUT Tip: IN To the output jack of the external processor CAUTION The signal output from the INSERT jacks is reverse-phased. This should not be a problem when connecting to an effect unit, but please be aware of the possibility of phase conflict when connecting to other types of device. A reversed-phased signal may result in degraded sound quality or even complete sound cancellation. MW12CX 16 MW12CX/MW12C Owner's Manual
