Wheatstone IP88-3A Analogue Input/Output Blade

In stock
Brand: WheatstoneWheatstone


The IP-88A-3 converts each hardware physical input -- audio or logic -- to a data stream on the network, and converts data streams to hardware digital outputs. It handles analogue input and output, each with eight stereo channels, 16 mono channels, or any combination totaling 16 discrete channels. It also provides twelve channels of universal logic (GPIO); all signals are routable anywhere on the WheatNet-IP network.


I/O BLADEs are far more than mere access units connecting studios, elements and Wheatstone control surfaces in the WheatNet-IP Intelligent Network.

Yes, I/O BLADEs convert audio and logic inputs to data streams on the network and convert outgoing data streams to hardware outputs.

But these 1RU I/O units – which come in analogue, digital and analogue/digital I/O units - also have intelligence inside. Each I/O BLADE comes with a CPU and operating system so you can do amazing things with your audio network, starting with routable mixing, logic-follow-audio and a whole lot more. 

Each of these access units, or BLADEs, communicates at lightning speed across the network via Gigabit Ethernet interface, and includes logic control, utility mixers and a dedicated controller that gives it its own intelligence. Each BLADE holds the entire brain trust of the studio operation for exceptional redundancy and scalability. 

Every WheatNet-IP BLADE access unit is self-aware, and can reconfigure itself in an emergency. In fact, each BLADE in the network can recover settings for your entire studio operation!

More than a mere node, this BLADE has two eight-channel utility mixers for mixing, summing and controlling audio. With all that functionality built-in, this sleek unit could save you up to 50% in network hardware costs alone.
