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.

Control all codecs 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.


Audio presence indicators and remote vu-meters can be deployed to provide the In- and Output Level indication for each AudioCodec regardless of its location.

Control Phoenix includes an agenda with copying functions, which allows to have a central and individual agenda for each codec.

External synchronism
• Possibility to synchronise the AES/EBU outputs with the Input sampling frequency.

Encoding modes

Encoding algorithms

AEQ recommends the use of OPUS algorithm. Equipment provides OPUS with Fs= 48kHz, mono, stereo, selected 4 mono and 3 stereo modes, bitrates between 12 and 192 Kbps, bandwidth between 6 and 20 kHz.For compatibility with other AEQ and third party  equipment , Venus 4 can work with a wide selection of algorithms; G711 Law A, Law u, G722, AEQ-LD, MPEG 1 and 2 – LII, linear PCM, and others on request.

Connection tools

Smart RTP
To simplify the operation of the unit, AEQ offers the Smart RTP automatic call set-up mode.
SIP Server
In addition, it offers Phoenix VENUS 4 and VENUS 4+ users the services of its own SIP server at no additional cost. Features subject to change without notice.
SIP Relay
Optional SIP Relay service to facilitate audio transport via a trunking server.
Optional SMARTALK service that generates web links for PCs or mobile devices to instantly download an OPUS audiocodec from the cloud that automatically connects via a SIP server to the audiocodec.
