Description

Relay switch analogue symmetrical audio signals consists of 4 independent channels, each of which provides switching between 2 signal sources to a common output by external control command GPI, or with the help of the button "A / B" located on the front panel of the switch. When pressing the button "A/B" unconditional switching of all 4 channels takes place, the released position of the button allows channel-by-channel (independent) switching between inputs using external GPI control signals. Switching of signals is asynchronous.

In case of power failure, the switch outputs are connected to the main inputs. The switch has two power supplies to connect it to two independent network feeders. For normal operation of the device it is sufficient to connect at least one power supply.

The front panel of the switch has mounting holes for installing it in a telecoms rack or console of standard 19" width.
