SPEAKERS SETUP AND LEVELS SETUP
SPEAKERS SETUP
Speakers size
The first few adjustments tell the SR-19EX which type of speakers are
in use. This is important as it adjusts the settings that determine which
speakers receive low frequency (bass) information.
If you use full THX speaker systems which are approved by LUCASFILM
LTD, set to the
SMALL/THX position for front L/R ch., center ch. , surr. L/
R ch., surr.back ch, and then select subwoofer =YES.
In turn, these settings will determine which speakers receive low
frequency (bass) information.
For the purpose of establishing proper bass reproduction, use the
LARGE settings if the speaker being used at any position is a
traditional full-range loudspeaker that is capable of reproducing
sound below 80 Hz.
Use the SMALL setting for smaller, frequency-limited satellite
speakers that are not able to reproduce sounds below 80Hz. Note
that when “small” speakers are used, a subwoofer is required to
reproduce low frequency sounds.
Low frequency sounds from every channel in your system can be fed
to a single subwoofer, since low frequency sounds are non-
directional and not location sensitive. The SR-19EX will automatically
send low frequency signals from any channel set to “SMALL” to the
Low Frequency Effects (Subwoofer) channel.
Remember that the “large” and “small” descriptions do not refer to
the actual physical size of the speakers, but to their ability to
reproduce low frequency sounds.
If you are in doubt as to which category describes your speakers, consult
the specifications in the speakers’ owner’s manual, or ask your dealer.
SPEAKER TYPE AND POSITIONING FOR THX SURROUND EX
Type
THX suggests the use of pair of dipolar speakers for the Sb channels
but a pair of monopole type speaker may also be used.
Positioning
It has been found that an angle of 150
°
from the Front Center speaker
is a good starting point for establishing the location of Sbl and Sbr
speakers. This is suggested from AES preprint #4860. The optimum
position for Surround Back speakers is somewhat room dependent.
The Surround Back channel should be enveloping but not lost in the sound
of the side speakers. Most dipoles have an arrow on them to indicate their
orientation towards the screen. So for the side dipole, the arrows point
forward. For the back dipoles, the arrows should point towards each other
to achieve the correct acoustical phasing in the room:
