Control Software

Control Phoenix

Control and configure your equipment from your computer.
All front panel controls are available in the CONTROL PHOENIX PC application, which allows you to remotely configure and operate an array of audiocodecs.

All codecs can be controlled on the network (local or remote) from one PC. An optional multi-codec application allows to detect all AEQ IP audiocodecs in a local network to control them in a coordinated way from a PC or group of PCs. It also allows remote equipment to be controlled via the Internet, favouring a comprehensive management of the communications network.


All front panel controls are available in the CONTROL PHOENIX PC application, which allows remote configuration and operation of a fleet of audiocodecs.

Audio presence indicators and remote vumeters can be displayed to facilitate the indication of the level of incoming and outgoing audio on each device, regardless of the location of each piece of equipment.

It incorporates an agenda with copy functions, which allows to have a central and individual agenda for each codec.
