DETAILED DESCRIPTION OF THE INVENTION In the present invention, a pseudo 4 (1) in 4channel amplifier is normally equipped with a single amplification system for rounding of a 4channel sound source independently in a 4-channel amplifier. It arranges four speakers on the
left and right and back left and right to generate a three-dimensional sound, but in the case of 4channel amplification like e, in the case of a 2-channel sound source, the left and right Only the
speakers are separated and there is no cane coming out, and there is no 4-channel true sense of
presence from stunned jin and niece. On the other hand, there are overwhelmingly many records,
tapes, etc. for 2 channels at present as Nakundo source, and those for # 4 channel increase. As a
matter of fact, even those for% 2 channels also coexist in large quantities, and even if they are for
umbrella p and amplifier (4 channels), the original function can not be fully exhibited. Therefore,
for the purpose of extracting some of the functions of the four-channel amplifier, it is conceivable
to use it as a pseudo four-channel. That is, the 2-channel sound source Honjo-oki signal is given
to the front left and right speakers to operate normally, and no signal such as 4 is given to the
rear left and right speakers. The signal at the left and right is output at the same time as that of
the other speaker at the rear, and this signal and the signal 1aO7j phase 1 is supplied to the
other speaker II! A similar 4 channel system has been adopted, and in order to obtain such an
effect, the conventional l14m4 channel-consulting technique is based on its guidance using
Tokunnu. Among the 4 being used, the bridge circuit is constructed and the signal arrangement
(31 is taken out, so there is something that is not so good-the expansion impedance of the former

one is low and the increase is sl- There are 4 of Toll, 11 of the Jh 4 which have the drawbacks of
the complex that the path construction is complicated and the adjustment is decoupled. In
addition,% of the conventional quasi 4-channel system F 1%, the signal given to the left and right
speakers is the difference between the front left and right)), right and left)) $ phased and the
front left acid content of the hoar Right handedness is not given to the left and right rear
speakers, its rounding, from one life that is a pseudo 4 channel system to the last, depending on
the birdhouse may be heard from the outrageous of synthetic sound from the outrageous . The
left and right speakers are given to the left and right speakers, leaving some good signal
components) and given to the left and right rears corresponding to them + 4) Car to adjust the
plaster to its directionality Because it is required to be done by 0 in order to get the 11 sense of
nature 11-11 ItLh.
The purpose of this device is to make it possible to obtain a pseudo-four channel all with an
impedance matching with a simple structure and a simple way configuration as well as a natural
presence: each of the ninety-four guns independently In four-channel amplification with an
amplification system, any two systems of amplification systems t * are used as the input field of
two tubes, and the guns of two transistors are used. And the resistance value of each of the two
separate input signals via #kIIt, and the difference between them is determined by leaving the
components of the group of input signals of the two systems, and (5) these are respectively
determined by the above It was given to the amplification system of two lines of two lines and
different lines of work, so as to procure each second line gun at each increase in the line @ line of
S line and to perform amplification of large signals respectively). Than is. One example of this
invention based on both! I hesitate. Jhs preamps @-()) each having input terminals 11) 1m) (3)

round amplification system is configured, and the preamplifier (5), the main amplifier (11), the
front left speaker, the preamplifier (6), the main amplifier wheel, and the wax front right speaker
-4, 1 # pump (7) and May amp 11 are rear left shoulder speakers-. In the case of the right
amplifier and the main amplifier, the right side for the right-handed sobi ★-one united with it,
the input terminal (1) (d) (from When the If is given, each amplification system amplifies the No.

These paces company resistance I8 (goods) are connected to the power supply terminal (d) and%
t is connected through resistance @ (d). The collector resistance% (am) of each transistor (g) is
connected to the power supply terminal (−) via the light source resistance (a), and the emitter is
connected to a power supply terminal (am) to be connected to the emitter. 9. The collector of the
transistor and the emitter of the transistor (c) are aggravated through JIIIlts of different
resistance values, and these resistances (d) are (2) An output terminal connected to the main
amplifier 11 is connected via the. Furthermore, the resistance of the transistor 18) and the
collector of the transistor are respectively ** via resistances of different resistance values, and
the capacitor I is interposed between the solder piles rs- The output terminal-is closely read by
the main ang I. In this case, the resistance (-) and the Fi resistance value are equal, and both the
resistance (-) and the resistance value are strong, and the resistance (-) of the resistance (-) is the
resistance (-) It is set to be bigger than that. In such a configuration, if the Pound North is for 4
channels, a signal is given to each of the input terminals (1) 12 41, and the preamplifier i 57 (67

and the synthetic sound by these 1; is different to the listener and greatly enhances the threedimensional presence. However, even if the source is a two-channel (9) input power terminal (1)

the front left preamplifier (5) is applied to the input terminal (d), the signal of the front spring
preamplifier (6) is applied to λ ladder, and thus each pace of the transistor and (d) When the λ

At the output terminal (t) side, the signal component of the input terminal a9 is emitted
corresponding to the value of the resistance (d), and the rear right speaker a @ is operated. Even
when different signals are given to the pre-input terminal ash, the signal generated at the output

extreme case, when the signal is given only to the input terminal (2), the output terminal (III- has
a different phase, and seven strong i5 also cause JIL remarks). In this way, the left and right

to a sense of presence. As a result, the sound source for 2 channels is also used by the sound

transistors. If the input impedance is high enough for practical use ■ suitable for stepping, take
the difference between the signals of the two systems) and emphasize the distribution of the
