le to send the audio over Ethernet using the COBRANET™. Standard. 2 FUNCTIONING DESCRIPTION The ZES-22 allows both, the injection and extraction of analog audio channel in a network of Ethernet COBRANET™. COBRANET™ allows up to 65536 “bundles” (where a ´bundle´is a package with up to 8 channels of digital audio). A ZES-22 can get up to 4 input channels and 4 output channels within the COBRANET™ network. These channels can be connected to any of the analog channels using the internal array. Also, it has a digital system integrated with the signals (DSP) being able to make signal gain adjustments, equalization, filtering, limitations, etc. Figure 1: Internal Diagram (Default) LDA Audio Tech - Severo Ochoa, 31- 29590 MALAGA, SPAIN.

: Port X, only available in some models. Configuration for FW 1.0.4 or higher for ETX v05 plate.(*) Table 1: Connections Description (*) Versions of HW V05 are recognized by software by the MAC address. Those start with a different number of: 00: 50: c2 .... or 70: B3: D5. 2.1.1 ANALOGIC CONNECTION The ZES22 accepts and manages the devices of balanced and unbalanced audio. The following diagrams explain how to connect different types of audio devices. 2.1.1.1 UNBALANCED SOURCE INPUT To be able to connect an unbalanced source of 2 wires to the ZES22, you have to connect the positive output of the unbalanced source to the positive I/O input of the ZES22. Connect the ground input source with ZES22 main source, and unite the negative input with the ground source of the ZES22 input.
