With the release of the version 3.3.1 drivers for Windows XP/Vista and Mac OS X, PreSonus’s hugely popular FireStudio Tube and FireStudio Project FireWire recording systems have just taken a quantum leap in functionality. This new driver provides multi-unit support, meaning you can now daisy-chain multiple FireStudio Projects and FireStudio Tubes in pretty much any combination, creating systems that fit in just a few rack spaces, yet have an extensive (and impressive) number of ins and outs. Two and three units daisy-chained in any combination has been tested at PreSonus, however, be aware that the number of units that can be daisy-chained in your setup depends on your computer’s processor speed, amount of RAM, and computer configuration. Let’s say, for example, that you have a FireStudio Project and a FireStudio Tube. With driver version 3.3.1, you can daisy-chain the two units to create a 26-input system! Add another FireStudio Tube and get another sixteen analog inputs with ten microphone preamps! That’s a 42-input recording system with a total of 28 mic preamps – all in just three rack spaces!!
Note that the inputs and outputs on each unit in the chain remain independent from one another, so you cannot monitor the inputs of any unit in the chain through the outputs of any other units in the chain, but you can easily create a mix within your DAW.
