The Dolby surround which reproduces a surround
intelligence applying a delicate time delay to the difference signal added to
2usual ch signals (L-R) is supported.
Two surround functionalities,
matrix surround and hole surround, are carried.
It spreads by taking out with matrix surround the signal which added the
negative phase component of opposite ch for 2ch signals which mixed a little
signal on either side conversely from rear from a front, and admiration
surround, rear か and others reproduces 2usual ch signals from a front, applying
an echo to the composite signaling of (L+R).
The input of four visual
equipment and the input terminal of one audio equipment are carried.
Simultaneously, two monophonic outputs convenient for an interconnection of the
output-terminal which can be edited up to three sets, and a subWoofer and a
center channel are carried.
The stereo power amplifier which can drive a front or the speaker of rear
is carried, and it is. This amplifier carries the independent input terminal
and can operate independently.

all the surround selectors and volumes can be controlled.
decoder's excess of a maximum permissible input will switch on the overload
indicator which tells it.
Three kinds of volumes, a master volume, 4
mode balance control volume, and each channel independent volume, are carried.
The one-touch preset volume functionality (sound memory functionality)
is carried, and the memory of a favorite sound volume and balance can be carried
out to three kinds.
The hole effect control functionality in which the amount of sound echoes of hole surround can be adjusted is carried.
remote control which can operate the surround change in the 3 modes, volume
control and a balance coordination, volume memory, etc. is attached.
control of video systems, such as NECVC-N8HF-N31, N5, N3, N63, N65, etc., is
also possible for this remote control.
