Getting Started - Focusrite Saffire PRO 40 User Manual

Getting Started

The Saffire PRO 40 has 2 x 6 pin Firewire ports on the back. You can connect your computer to either Firewire port, and this
will work with any of the current Firewire standards and connections; Firewire 400 (6 pin or 4 pin connection); and Firewire 800.
BEFORE YOU CONNNECT THE SAFFIRE PRO 40 TO YOUR COMPUTER, PLEASE RUN THE INSTALLER. This will ensure that the
correct drivers are used, thus preventing any unexpected behaviour
The Saffire PRO 40 requires power, supplied via the included power cable.
The Saffire PRO 40 ships with a 6 pin Firewire cable. However on Windows laptops, the Firewire connection may be 4 pin Firewire.
If this is the case with your computer, you will need to purchase a 6 pin to 4 pin cable.
You may have a Firewire 800 connector on your computer. In this case you will need to purchase a 6 pin Firewire 400 to 800 cable.
Note:
Firewire considerations - Most computers will generally be equipped with 1 Firewire bus. You may have multiple Firewire ports
(connectors) on your computer, but these are all connected to 1 physical chip which controls the bus.
The Firewire chip is limited in the amount of data bandwidth it can handle, so the more Firewire devices connected to the Firewire
bus, the more data the bus needs to handle, and the greater chance there is of having more data than can be dealt with.
The Saffire PRO 40 should be able to work along side other devices connected to the same Firewire bus. However whether this
will work for you will depend on what other Firewire devices are connected, and what they are doing. For example a Firewire disk
used for back-up or a digital camera should not cause any problems; but when using a Firewire hard disk that is streaming all your
samples, or a Firewire DSP box such as Focusrite Liquid Mix, (i.e. when there is a lot of data streaming on the Firewire bus,) there is
a chance that more data is streamed than the Firewire chip can handle. This will result in audio drop outs, or reduced performance
on either the Saffire PRO 40 or the other connected Firewire device.
For this reason, we would recommend that you use a separate Firewire bus for each Firewire device. This may be a PCI / PCIe card
in your desktop, or a PCMCIA or Express card in your Laptop.
