EtherSound ES8in/ES8mic/ES8micCL

8 channel EtherSound audio bridge
ES8in / ES8-Mic / ES8micCL

Key Workflow: Insertion of eight analog mic or line level audio channels to a 100 Mbps EtherSound nework

ES8 products allow converting eight analog intputs to eight EtherSound channels.
ES8in accepts line level signals, whereas ES8mic versions accepts mic or line level signals allowing to directly connect up to 8 microphones to the EtherSound network.

At a glance

ES8 products feature 8 balanced analog inputs that are inserted to an EtherSound network. While ES8 handles line level analog signals, ES8mic and ES8micCL allow direct connection of dynamic and static (condenser) microphones. Compared to the ES8mic, ES8micCL adds an analog compressor/limiter/noise gate to each input.

All the parameter od ES8 products can be remotely controlled from the EScontrol software application.

ES8 are available with XLR connectivity, or terminal block connectivity.
