Controls and Connectors Rear input/output block Channel I/O connectors section CH25/26-31/32 {CH17/18-23/24} CH1-24 {CH1-16} Master I/O connectors section Power section Channel I/O connectors section q Mono inputs • INPUT A: These are balanced XLR-3-31 type input jacks (1: Ground; 2: Hot; 3: Cold). • INPUT B: These are TRS phone-jack type balanced inputs. You can connect either balanced or unbalanced phone plugs to these jacks. NOTE On any given channel, you may use either an XLR or phone jack, but not both. • INSERT: These are unbalanced TRS (tip=send/out;, ring=return/in; sleeve=ground) phone-type bidirectional jacks. You can use these jacks to connect channels to devices such as graphic equalizers, compressors, and noise filters. NOTE Connection to an INSERT jack requires a special insertion cable as illustrated below. Use a separately-sold Yamaha insertion cable (YIC025/050/070). To the input jack of the external processor To the INSERT jack Sleeve (ground) Ring: IN Tip: OUT Tip: OUT Tip: IN To the output jack of the external processor w Stereo inputs • LINE: These are stereo input jacks that connect linelevel instruments, such as a CD player. These are unbalanced phone-jack and RCA pin-jack line inputs. NOTE On any given channel, you may use either a phone or RCA pin jack, but not both. Master I/O connectors section e MATRIX OUT (1, 2) These are impedance-balanced (*) TRS phone jacks. These jacks output the signal adjusted by the knobs in the MATRIX section. * Impedance balanced Since the hot and cold terminals of impedance balanced output jacks have the same impedance, these output jacks are less affected by induced noise. r MONITOR OUT (L, R) These are impedance-balanced(*) TRS phone output jacks that you connect to your monitor system. These jacks output the signal before or after the faders for the various buses. The PFL and AFL indicators in each section indicate which signal is being output. NOTE The PFL switch has priority when both the PFL switch and AFL switch are on. To monitor the post-fader signal, make sure to turn off all PFL switches. 22 MGP32X/MGP24X Owner's Manual
