General
The AMS-4171 consists of one "video" and two "balanced audio" switches. Each switch is arranged as a changeover set with two inputs and two outputs. No terminations are provided on the board allowing the switcher to be used in a wide variety of applications and with signals of various types and impedances.

The "video" path uses enhanced performance relays to provide switching capabilities for high-speed data signals up to 1.485 Gb/s and may be used with analogue video, SDI, HDSDI, ASI or G.703 data signals.

The "audio" path may be used for balanced or unbalanced audio or control signals (RS232, RS422, RS485 etc).

The AMS-4171 is ideally suited to applications where a simple choice between two inputs or outputs is required and may be easily driven by audio, video or other detector circuits for automatic path selection.		 Front panel switches allow a choice of local or remote control operation.

Front panel LED indicators are used to indicate the status of each relay circuit.

Remote control is via a switch to ground connection, where video and audio may be operated independently or with audio following video by means of link settings.

An optional SNMP (Simple Network Management Protocol) plug-in module is available for remote monitoring and control when used in conjunction with IRT's 4000 series frame fitted with SNMP capability.

The AMS-4171 is designed to fit IRT's standard Eurocard frames as well as IRT's 4000 series frame for use with IRT's SNMP system and may be used alongside any other of IRT's analogue or digital Eurocards.
