SURROUND VIA HEADPHONES
Please note that you cannot control a surround mix by using headphones. Firstly,
all channels fed to the headphone output would have to be mixed, which is not an
option that is available on conventional headphones. Secondly, no standardized
surround headphones that could produce a correct surround playback are
available on the market!
The so-called "surround" headphones create only a virtual surround sound space
generated from a single stereo source (!) and can not reproduce a true surround
signal!
Some systems such as AKG
Prologic and DOLBY
surround signal into a binaural ("two-ear") audio signal to be played on
conventional headphones.
Even the YAMAHA
receivers/amplifiers merely uses the internal DSP chip to generate virtual
surround effects for conventional headphones.
"GAPS" WHICH MAY OCCUR DURING SURROUND PANNING
When you modify a sound source in a circle, "acoustic gaps" may occur, or
you may perceive acoustic jumps from one speaker to another. This is by no
means a defect of the surround option of the DDX3216, it is a normal
phenomenon that occurs on all 5.1 surround systems.
The reason is the fact that 5 (+1) loudspeakers can not perfectly cover any
one area. Theoretically, a more ideal solution with far greater uniformity of
coverage would be an 8 (+1) system. The current standard (supported by the
DDX3216) is a 5.1 surround system; you should be aware of the limitations of
"rotating".
SURROUND MUSIC
Surround sound in pure musical productions is still a relative novelty, aside
from the failed attempts at achieving quadraphonic sound. There are no
universally accepted guidelines for surround music productions. DVD audio is
