Monitor engineer Renato Carneiro works with Brazilian artists Zeze di Carmargo, Luciano and Os Mutantes.
On the L/R bus of the desk, I build a full mix and then route this send to two channels. In an analog desk, I put a pair of cables on the L/R outs to two free input channels. On a digital board, I use a free EFX machine, bypassed (you can select a multiband compressor on this machine and master your main mix), defining the input of the machine as the L/R send and the outputs as two free input channels paired in stereo. This full mix — through these channels — is then sent to the all the band's in-ears. Then I sum the inputs that each bandmember would like to hear louder in their mixes.
