Apple Logic Pro 9 - Manual (Page 34)

Note: Condenser microphones require power to function. This can be provided by a
separate pre-amplifier or a phantom powered mixing console.
Connecting Your Audio and MIDI Devices
You need to connect your external audio and MIDI devices to your computer to allow
communication between Logic Pro and the devices. The following sections introduce
you to Mac expansion capabilities, audio and MIDI cabling, and other things you should
consider when connecting audio and MIDI interfaces to your system.
Computer Expansions
Depending on your Mac system, some or all of the following expansion capabilities are
available, which can be used for audio and MIDI interfaces:
• FireWire (IEEE 1394)
• USB
• PCI Express
• ExpressCard/34
Note: Data transfer rates discussed in the following sections are theoretical maximums.
In real-world use, this will be reduced due to system overheads. In general, protocols with
faster theoretical maximums will deliver data more quickly than slower protocols.
FireWire (IEEE 1394)
FireWire is a professional and consumer standard that can be used for both audio and
MIDI devices, as well as hard disks and other peripherals. It combines fast data transfer
rates, high storage capacities, and plug-and-play connection. All current Mac computers
offer FireWire connectors, and a number of FireWire audio and MIDI interfaces are available.
FireWire 400
FireWire 400, also called IEEE 1394a or i.LINK, is the consumer and professional standard
for formats such as DV, DVCAM, DVCPRO, DVCPRO 50, DVCPRO HD, and HDV. FireWire is
an inexpensive and easy way to capture and output high-quality digital video using a
variety of camcorders and decks and is capable of data rates as high as 400 Mbps. Standard
FireWire cables can be up to 4.5 meters long.
