RV-8 Setup
3-39
During the microphone check, DO NOT:
7 Separate the microphones
7 Scatter the microphones throughout the listening
space
7 Obstruct the line-of-sight path between the micro-
phones and the speakers
7 Position the microphones on the floor, on seat
cushions, or in locations obstructed by furniture and
other fixtures, where echoes might obscure
calibration noise signals
7 Position the microphones within 2 feet (0.61m) of
speakers and walls or more than 30 feet (9.14m)
from any one speaker
The illustration to the right provides an example of
improper microphone placement during the microphone
check. The microphones are scattered throughout the
listening space rather than positioned as close together as
possible in a location that is equidistant from the front left
and right speakers.
