2.9.3 Theater Equipment Check
Prior to adjusting the EQ, please check all of the components in the audio system for proper installation
and operation.
2.9.3.1 Speakers
 Check that all speakers ar
e properl
y mounted and secured. Ensure there are no loose parts
or mounting hardware left around the speakers that could be a source of noise or rattles.
 Check the aiming of all speakers. Verify there are no obstructions in front of the speakers.
Ensure that, if equipped, the masking, screen frame, and sound wall do not block the
speakers.
 Verify speaker cables are secured to the speakers and are of a suitable gauge.
 Verify each speaker has no missing or open drivers.
 Check that all speakers are connected to the correct channel.
 Verify that the high and low frequency drivers for each channel are in phase. Also, check
each channel is in phase with the others.
2.9.3.2 Amplifiers
 The gain settings of all the screen channel amplifiers and surround amplifiers should be
roughly the same. If a particular amplifier requires a vastly different gain setting or
operates differently than the others, it should be checked and repaired.
 Check all of the amplifiers for distortion or noise.
 Verify that the cooling fans are operating correctly and that the air vents are clean and free
from obstructions.
2.9.3.3 Theater
The theater should have all of the acoustic treatments installed prior to setting the EQ. Any
excessive noise from air conditioners, hallways or other sources should be minimized. All
theater seats must be installed. Remove any plastic coverings from chairs or speakers prior
to any EQ (Audio) alignment.
2.9.4 Assign Channels on RS20i
After installing the RS20i and connecting the cabling for inputs and outputs, the next step is to assign
channels.
The RS20i allows custom defined channel names for the input channels. The input channels are named
through the Channel Names screen.
In general, the default assignments must be preserved for the first 8 channels in order to maintain
compatibility with the HDMI input channel assignments, and with the Hearing Impaired output channel.
Default channel names are listed in Table 8 below.
