Multi-Channel Stereophonic Philosophy
LX901 LX801 LX701 LX502
In a multi-channel system, all adjacent channels should be
stereophonic—that's the concept of Pioneer's Multi-Channel
Stereophonic Philosophy. In a normal stereo reproduction, the same
type of speakers are placed at equal distance from the listener, and
driven with the same amplifier. Similarly, for an ideal multi-channel
reproduction environment, all channels should have the same
speakers, placed at equal distance from the listener, and driven by
the same amplifier. However, such arrangements are physically and
economically difficult in a home setting. For example, it wouldn't be
practical to fix the same type as the front speakers on to the ceiling
as top speakers. The shape of the room and furniture placement will
also limit speaker positions. So Pioneer developed the following
three steps to create the ideal reproduction environment within a
home.
[ m i n a m o t o ]
Step 1
"Direct Energy Design" technology that realizes simultaneous high-power
output for all channels.
Selection of optimal parts and incorporation of cutting-edge technology.
[ w a z a ]
Step 2
Automate the monitoring methods of professional studios and create the
"Ideal Reproduction Environment."
Measure the listening environment's features and compensate the speaker
size, distance, frequency characteristic, and phase with DSP technology.
[ t a m a s h i ]
Step 3
"Sound Tuning" by professional engineers brings out the "master sound."
The master sound made through these steps reproduces audio just
as the creator intended, offering an immersive sensory experience.
Additionally, with the latest object-based surround sound formats
such as DTS:X and Dolby Atmos , you can enjoy incredibly rich
®
multi-dimensional audio in sync with what you see.
