Chapter 1 Setting Up Your System 17
PCI (Peripheral Connect Interface)
PCI interfaces, unlike FireWire and USB interfaces, require that you install a dedicated
sound card in your computer. PCI provides high bandwidth and fast data-transfer rates,
allowing you to record and play back large numbers of files at the highest possible
sample rates and bit depths.
PCMCIA
PCMCIA is a consumer standard for connecting devices to a laptop computer. PCMCIA
provides a lower data-transfer rate than FireWire or USB, but provides a compact,
affordable solution for connecting an audio interface to your computer, while keeping
your USB and FireWire ports available for other devices. Most current Macintosh laptop
computers support PCMCIA connections via a built-in card slot.
Audio Cabling
There are several types of audio cables and connectors used on professional and consumer
audio equipment, at a range of prices and levels of quality. When connecting microphones
and musical instruments to an audio interface or a mixer, make sure the interface has the
proper input jacks for the type of connectors and cables you plan to use.
XLR
XLR cables and connectors are used on professional-quality microphones, monitors, and
other musical equipment. They provide a high-quality, balanced signal at +4 dB level.
1/4-Inch Audio
1/4-inch connectors (sometimes called “phone plugs”) are used on a wide variety of
professional and consumer musical equipment, including musical instruments and
amplifiers, speakers, and external effects devices. They can be either balanced (+4 dB)
or unbalanced (–10 dB). Some devices require Tip-Ring-Sleeve (TRS) connectors to
transfer the audio signal.
