The AoIP44 is an economical subrack designed to interface balanced analogue audio circuits to and from a Network audio system featuring Dante. It provides 4 audio inputs to the network and also 4 audio outputs from the network on balanced 3 pin XLRs. As well as being mains powered with the standard signature backup DC powering option, the AoIP44 can be powered from an external PoE source via its network interface.

The AoIP can be used as a simple low cost audio I/O break out unit on a large Dante audio network where it can be integrated extremely easily using the Dante controller and is fully compatible with any manufacturers Dante equipment. It can also be used in very simple audio over IP scenarios where just 4 bi-directional audio circuits are needed to be distributed across a building's network infrastructure, in which case 2 x AoIP44 units can be used connected together across the network. The AoIP44 is equally suited for high integrity broadcast purposes, intercom, just simple paging facilities or simple distribution of non-critical audio.

Being part of our Signature Range the AoIP44 comes as standard with removable rack ears (to allow front or rear mounting in 19" racks), mounting holes to allow under desk mounting (the holes are equally suited for screwing the unit into odd places!) and an optional external DC power supply for applications requiring redundant power supplies. It is housed in an all anodised aluminium chassis.

The AoIP44 uses a chipset called 'Ultimo' supplied by Audinate (The people behind Dante). This Ultimo chipset runs firmware that provides the processing for the audio over IP circuits. 

Audinate updated the Ultimo chipset to become an Ultimo X4 chipset.  We started supplying AoIP44s fitted with the X4 variant around the end of 2017.

The original Ultimo chipset and the Ultimo X4 require different firmware. It will not do any damage loading the wrong firmware into either the Ultimo or Ultimo X4 chipsets, so if you're unsure which you have fitted try one and if it doesn't work try the other.    

Latest Version of the Ultimo Chipset Firmware:

Latest Version Of The Ultimo Chipset Firmware is AOIP44_v1.1_Dante_v4.0.10.2 Ultimo4

The download location of the above file is: Ultimo4.dnt

Latest Version of the Ultimo X4 Chipset Firmware:

Latest Version Of The Ultimo X4 Chipset Firmware is AOIP44_v1.1_Dante_v4.2 Ultimo X.dnt

Please note these addresses are locations of the files and not web pages, if you put the above address in your browser it should automatically download the file. You may see ‘page not found’ but all that you actually need is for the file to be downloaded.  


The firmware that runs on the Ultimo chipset is updated using Audinate’s Firmware updating tool. The updating tool and a user guide can be downloaded from Audinate’s website:

Please note we strongly advise that when you do the update, only your PC and the AoIP44 that you want to update are on the network to save accidentally updating the wrong Dante device.
