L
LFE
This is an abbreviation of Low Frequency Effect, which is an output channel
that emphasizes low frequency effect sound. Surround audio is intensified
by outputting 20 Hz to 120 Hz deep bass to the system subwoofer(s).
M
MAIN ZONE
The room where this unit is placed is called the MAIN ZONE.
Modem
Device that connects to your broadband internet provider, and is very
often supplied with the service.
A type that is integrated with a router is also often available.
MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data compression scheme,
using the “MPEG-1” video compression standard. It compresses the data
volume to about one eleventh its original size while maintaining sound
quality equivalent to a music CD.
MPEG (Moving Picture Experts Group),
MPEG-2, MPEG-4
These are the names for digital compression format standards used for the
encoding of video and audio. Video standards include “MPEG-1 Video”,
“MPEG-2 Video”, “MPEG-4 Visual”, “MPEG-4 AVC”. Audio standards

Progressive (sequential scanning)
This is a scanning system of the video signal that displays 1 frame of video
as one image. Compared to the interlace system, this system provides
images with less flickering and jagged edges.
Protection circuit
This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
If a malfunction occurs in this unit, the power indicator blinks red and the
unit switches to standby mode.
S
Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the “sampling
frequency”. The larger the value, the closer the reproduced sound is to
the original.
Speaker impedance
This is an AC resistance value, indicated in Ω (Ohms). Greater power can
be obtained when this value is smaller.
