GPS722 is the 2:1 system switcher which implemented XLR and a BNC connector.
The function that can switch analog and digital audio signal to secondary from a primary system with locality or remote is most suitable for emergency broadcasting system.

“Basic control”
It is possible for choice of momentary contact or the alternate contact to command mode of GPI port 1 by the setting of the internal switch.
(at the time of an order)
It becomes “REMOTE” mode at the time of the power-up, and primary is chosen.
In this state, it is switchable by a command from GPI port 1 in primary or secondary.
Operation with the front panel is enabled when it switches it to “LOCAL” mode.
It does not accept all remote commands in this state, but the tarry is output.

“Sub control”
Control is possible in GPI port 2.
An application such as returning from secondary to primary automatically is thought about as a use example by an end tarry of the play of the equipment for emergency.
In addition, it does not accept the primary select command when DISABLE command is applied.
In addition, it can confirm the DISABLE input with LED of the front panel.
It does not accept a command with the “LOCAL” mode like GPI port 1.

“Switching”
The signal switch by the relay allows connection and a signal level with every equipment.
The action that primary is chosen at the time of power down is safe for emergency.

“Supporting signal”
It supports an analog audio, digital audio, word clock and a video.
In addition, it is most suitable for the applications such as a monitor speaker switch, the source selector because it uses a superior relay for sound quality.

“Termination”
It is loaded 600 Ω or 110 Ω between hot and the cold of the XLR input port which is not chosen.
Likewise, as for the BNC port, it is done a terminal at 75 Ω.
It makes analog or the digital choice with an internal switch. Likewise, as for the BNC port, it is done a terminal at 75 Ω.
