OVERVIEW   

 

Stereo Mixer 1U   is   a   versatile,   expandable   audio   mixer   for   the   Intellijel 1U   format.   It   has   two   pairs   of   
front   panel   inputs,   each   with   its   own   level   control,   and   a   mixed   output   pair.   For   each   input   pair,   the   
left   channel   is   normalled   to   the   right   channel,   for   mono   operation.  

Using   3-pin   Link   connectors   on   the   back   panel,   you   can   chain   multiple   Stereo Mixer 1U’s   together   in   
series,   giving   you   the   ability   to   mix   together   even   more   inputs,   or   to   create   sub-mixes   for   routing   
audio   around   larger   systems.   You   can   also   these   same   connectors   to   patch   Intellijel’s   Mixup   and   
XY IO 1U   modules   to   these   back-panel   chains,   and   you   can   connect   them   directly   to   the   ¼”   audio   
jacks   on   an   Intellijel   Palette   Case,   a   7U   case   with   2nd-generation   Audio   Jacks   Board,   an   Outs   
module,   or   a   v2   Headphones 1U.   

 

Because   Stereo Mixer 1U   is   designed   specifically   for   audio   (and   not   for   CV   mixing),   it’s   AC-coupled,   
and   uses   audio-grade,   logarithmic   attenuators   for   a   smooth,   even   response   across   the   entire   
volume   range.
