EtherSound ES220/ES220-L

Two channel EtherSound audio bridge
ES220 / ES220-L

Key Workflow: Insertion/extraction of two analog audio channels to/from a 100 Mbps EtherSound nework

ES220 is a full-duplex two channel EtherSound bridge that allows converting two balanced analog input channels to two EtherSound channels, and extracting two EtherSound channels to two balanced analog output channles.
ES220-L is the one direction version of ES220, and allows the user to configure it for inserting two EtherSound channels from the two analog inputs, or for extracting to EtherSound channels to the two analog output.

At a glance

ES220 and ES220-L  feature two balances analog inputs and/or outputs, allowing the connection of any audio device with two analog channels to an EtherSound network. Like the other EtherSound products, ES220 can be remotely controlled for the Digigram free software application EScontrol or any third party EtherSound control application.
