The Nyquist 2-channel Audio over IP (AoIP) Gateway provides customers with a bridge between analog and digital signal channels. The GA400P digitally encodes analog signals and transmits them over the network, where they are then decoded by a second AoIP device to provide line-level audio to analog systems, such as amplifiers, and analog paging or sound systems. Similarly, the GA400P can take analog audio signals, encode them in digital format and distribute them over the Nyquist network. The NQ-GA400P incorporates two balanced line-level inputs and two balanced line-level outputs, along with two Form-C SPDT-type 2-amp dry contact relays that activate when a signal is present on a corresponding line-level output. Designed to operate over a 10/100 Ethernet network, the NQ-GA400P AoIP Gateway is IEEE 802.3af–compliant and can be powered using Power over Ethernet (PoE) switch or PoE injector when a PoE switch isn’t available.
