SB168-ES has 16 remotely controllable, high quality mic pre-amp inputs patching to EtherSound and 8 line level outputs from EtherSound. SB168-ES units can be daisy chained together to provide up to 64 channels of analog input and 32 channels of analog output. Digital mixing consoles such as the Yamaha PM5D, M7CL, or LS9 can be connected to the SB168-ES for remote analog input and output interfacing on stage or wherever needed. This type of system eliminates noise problems that are unavoidable with conventional analog console plus multicore-cable type setups and dramatically reduces microphone cable length for superior sound quality. Cabling between the console and stage box units is also simplified for fast, easy setup.
