18 Chapter 1 Setting Up Your System

RCA

RCA connectors are used on consumer audio equipment such as home stereo systems

and videocassette recorders.

Optical Digital (AES-EBU and S/PDIF)

AES-EBU and S/PDIF are both used to provide an optical digital connection to

professional and consumer audio equipment, including audio interfaces, DAT (digital

audio tape) machines, hardware samplers. Both carry a stereo digital signal. AES-EBU is

balanced, and has an operating level of 5 volts, while S/PDIF is unbalanced and has an

operating level of roughly 1/2 volt. There are adapter cables available to convert

between the two protocols. S/PDIF carries additional information with the audio signal,

including SCMS copy-protection information.

1/8-Inch Miniplug

Miniplug connectors are used for audio input and output to computers and on some

consumer electronic devices, particularly portable ones.

Audio Output

Being able to monitor the audio output of your projects at a high level of quality is

crucial to achieving professional results. In general, you should use the best output

equipment your budget allows.

Speakers and Monitors

You can play back audio through your computer’s speakers or headphone jack, but the

audio output may not be high enough for you to evaluate your music at a professional

level of quality. Connecting external speakers or monitors to your system allows you to

hear the audio output with greater fidelity and a wider dynamic range. In general, you

should use the highest-quality speakers or monitors you can afford in order to hear

your projects at the highest level of audio quality.

For detailed information on connecting external speakers to your audio interface, see

the documentation that came with the speakers.
