Figure 33 on page 499 illustrates the speaker arrangements of each surround format. Speaker place-
ment for each format is approximate. For proper placement, alignment, and calibration of surround
monitoring systems, consult the documentation that came with your speakers and other monitoring
equipment. Placement of speakers is crucial to accurate monitoring of any mix, but this is especially
true with multichannel mixing for surround sound.
