transmission system J 紘 consists of, for example, recording and reproduction systems to a

decoder 4 by the transmission system 3 in the same manner as the ll1rlA system (the decoder 4
is a transfer circuit J having an equal phase shift characteristic, 40. This phase shift cycle, 7 + 4870601-08 · -4 pyess, has a phase shift object image 90 ° shifted from the phase shift

It is added to S 九 1 to perform three-dimensional reproduction of sound. However, both of the
above mentioned methods are compatible with each other! There are 5 big 11411 I good with no

with 4 units of the 4 ss by the decoder 4 of 1 ss WA, the a ss s s s s s s s 3 s s s 3 If Dyannell's
signal R18 is 18 to 4f Yannel in the 4th rg decoder 4, it is not possible to demodulate the gang in
a nearly satisfactory state, and it is impossible to obtain the second dannel stereo effect. This is,
as is apparent from the figure, the Engorda 2I; the signal conversion method in the phase
relationship of each signal and the ma)! Because the signal mixing method in the l's circuit is
different, 1) Therefore, from the vector diagram shown in FIG. Therefore, unless dedicated
decoders are used, they can not be demodulated in the state ("-@ + 48-70601-10, which is
extremely inconvenient, 7 and uneconomical. This device has been made in view of the above
situation C, and the purpose of the device is to convert a number of channel signals obtained
from the field into a plurality of 3 channel signals obtained by kC-conversion of 3 channels by
different conversion methods. The signal can be easily converted (demodulated) to the original
dannel's signal by t-Para 1 · iI placement, and very convenient! It is assumed that ll1r-like
acoustic signal conversion ** is provided5. This device is based on the following device. That is,
when the decoder 4m in the first II is rewritten, it becomes 5 as shown in FIG. (Note that each

phase shift characteristic of transition cycle @ II, I-is j! Even if this is done, there will be no layer
at all.) Also, if the decoder 4v in FIG. S is rewritten, it becomes as shown first. However, as shown
in FIGS. S and 5Ii3 or b, the decoder 4 in the fifth WJr- configures the matrix circuit @ 43 so that
signal mixing between the left and right data channels in the front, rear and rear is not
performed. Since the key signature and -10-48-7060i-114: ", J 'rear ax separeley v11 y is one
degree 5 ° there is a improvement in the above separage bran To both To and aft Each left and
right Dangne kr #! If matox rm * 4 J is configured so that the temperature of the signal at J is
performed, five cycles may be considered as shown in eaE-.
The ninth circuit and the seventh e! When comparing with the circuit of A, it can be seen that
both are very mat, thus sharing each phase shift circuit by switching the circuit of Figure 7 and
the looping of Figure 9 appropriately. There will be one thing you can do. From this point of
view, the present invention is configured to share each phase shift circuit, and selectively
switches the configuration of the matrix circuit according to the conversion system of the
encoder by the switching circuit * C, and the signal of the channel number is Different conversion
method documents: Therefore, the conversion of only three deyan signals to the three deyan
symbols For example, the three deyan signals of the slI class Je′′I and Ll # ′ ′ l by the same
device. Signal C is converted. Hereinafter, with reference to one embodiment t-rg plane of the
present invention;) 4B-706 () 1-12'Ai, '! 1! 7 ♂ II & sound. In the tenth layer, 11. II is an input
terminal for exclusively applying the three lines of the signals Lmsj or Ll * "l, and this input
terminal 11.2. One left-hand signal input terminal 11 of II is 11 at each input end of transfer alil
step II, 14. It is controlled. Further, the other group 91M signal input terminal 12 of the input

see phase shift characteristics. The threshold value layer is used, and one having a phase shift
characteristic which is 1Pj nine times from the shift m characteristic of the phase shift circuit xJ,
sg is used. Each of the phase shift circuits IIJJ to J # has a 5 cm configuration to operate under
the same conditions with respect to the frequency at which the gold channel is connected. Thus,
the output signals of each of the transfer m circuits JJA-s- are, respectively, the same circuit 1rCapplication 89. J-11, connect the vehicle power terminal J 9 cm through the output terminal line
