(See page 21.)
In a concert hall, the extent or shape, image
localization, and echoicness or anechoicness can be
appreciated even if the eyes are closed.
This is because sound reflections from all directions
are heard besides the direct sound from stage
(instruments or voices) simultaneously.
Our auditory sense can recognize the extent of the
hall by the time difference between the direct sound
and the reflections, the shape of the hall by the
directions of the reflections, and the echoic or
anechoic characteristic by the attenuations of the
sound. :
Therefore, simulating the time difference or direction
of the reflections and the attenuating time may
reproduce the sound field of an actual concert hall.
As sound produced by performers is reflected by all
objects in the hail, it is heard not only from the direct
front but also from the sides, rear or ceiling.
LSh-—1
These reflections cannot be reproduced by the
conventional 2-channel (2-speaker) system, but
require extra speakers to reproduce sound reflection
(this is called the sub speaker). The DSP-1 is
designed to reproduce the realistic sound field
experienced in a concert hall in a normal listening
room by simulating sound reflection from all directions
based on actual measured data, using extra speakers
surrounding the listener. Furthermore, the digital signal
processing circuit adopted in this unit can be used to
produce special sound effects, such as combining
phase-difference signals, changing pitch or changing

7 Source volume adjustment l
When playing the amplifiers input source, adjust with
the volume control of amplifier.
When playing the amplifiers input source mixing with
the MIX INPUT signal, adjust the volume with the
amplifiers volume control and the MIX INPUT LEVEL
control of this unit.
When playing the tape deck connected to this unit,
adjust with the TAPE PB LEVEL control of this unit.
When using the integrated amplifier or receiver having
no pre-out/main-in jacks, adjust the volume also with
the amplifiers volume control. a
& Balance adjustment
Using the MUTE key (MAIN, EFFECT) of the remote
control transmitter, adjust the level of the power
amplifier so that the source-only volume is equal to
the volume level of only the effect sound.
* When the volume control is not provided with the
amplifier for Source reproduction, set the MAIN
LEVEL switch on the rear panel of this unit to the
“—10 dB” position to lower the source volume.
With this adjustment, the difference of the volume
levels between speakers having different sensitivities
or amplifiers having different gains can be corrected.
When the sensitivity is different between the front and
rear sub speakers, select the “DELAY” program in the
SOUND EFFECTOR mode, and adjust the power
amplifier to this unit so that the volume level of the
front sub speakers becomes equal to that of rear sub
speakers. (In the ACOUSTIC/SURROUND mode,
balance between the front and the rear differs in each
sound field data.)
