The Epsilon 32-500 is a 32 channel summing mixer unique in the mixing market because it’s capable of combining 3 summing styles using only 1 machine. This means 3 different ‘’analog consoles’’ in 1 summing mixer. The 3 summing modes are: 500 series, Kahayan Bus and External Bus (see page 7). The Epsilon 32-500 is the first summing mixer that allows you to use 500 series modules. You can use their solid 4000 – 500 series modules or any 500 series preamp working as a summing bus (see page 7). Another unique aspect to the Epsilon 32-500 is the possibility to expand through the use of external rack modules (in External summing mode). These modules can add new summing styles. We recommend Kahayan modules like the Kahayan Vintage 12k72 or Solid 4000, and also preamps. Their equipment possesses the ability of expansion meaning it is in constant evolution. All components are hand-selected one by one. The Assembly is completely handmade. The Rack consists of 3 rack units of 35 cm depth. Furthermore the unit was conceived as a Summing Bus and can be used as mastering equipment using only two channels.
