DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a four channel
device, in particular, a volume, balance, three-way fadercon) reel device used in this blue tatami
mat device. User O Depending on the choice, noise or snareo sound. (Kotoku building 's
Marutoto' Noknaappupurea like a small bowl in the soup building ? ? ? small. The recent
ambition of the tri-channel audio system allows the playwright to be dispersed into the audio
range generated by the da separate speakers. So far the sound of the 41 rumors-the channel Mu '
Adjusting the volume or balance of the multi-channel sound station 111 such as that needed to
be done separately was rather a shame rather than a hardship. Such a dual channel sound reader
is incorporated into a cartridge type tape player. This type of tape player is widely used in
automobiles for the convenience of mastering the tape cartridge. In this type of tape braker, the
cartridge can be held by inserting the cartridge into the player simply and quickly, and the player
can operate the player mounting by itself, so that the driver can easily use the car while traveling
safely for example # 1 while driving- There are advantages to Such features Yr-containing
cartridge w-nerp blair includes a switch w that operates the tape playback mw as the cartridge is
fully inserted. In order to open the tape player, it is only necessary to withdraw the cartridge
partially or completely, and simultaneously with the end of the entire track of the tape in the
cartridge, the cartridge is automatically released by the nappe player and the acoustic load wI is
removed. There is a turtle. Although this type of tape player is a good catch, the corresponding
channel pair on the tape must be reproduced in monaural or stereo sound quality as compared to
a real orchestra. I did not know. However, it has been found through empirical # that Jl is more
open than the 7 ''-channel fl '' 1 H mono and Sanareo-devices. I wonder if the listeners should be
at the center of the voice, I! You can listen at any position of F9 rg within a range that can
change the 0-sentence speech generation pattern to give a feeling of being completely wrapped
in a eleven o'clock god. However, the Yoshi mentioned above and this are relatively different

purpose of the present invention is to make the listener easily located in the center of sound 1 as
well as being a construction crab area A poly, a balance and 7 ada controlled 11 paths for a
reference channel sound reproduction device which enables to obtain the relative balance

In addition, all seven units 7 + 1Q?-I'112 follow a single volume control element, and Z is
characterized by two. Although it is possible to provide DC power distribution used to control the
gain of each channel simply by following the balance or 7 ADA controller, the sum or total gain
of these channels is substantially 4 ? Do not change. -To explain simply 2 и k reference channel

the magnetic pick-up of a plurality of conversion devices such as pick-up elements or parts of V
And with the input terminal to supply another input signal from the tank! -Provide. The output
tubes of each channel are suitably connected to speakers or sound-playback devices. The
magnitude of the sound converted through each channel is controlled by the signal gain of that
particular channel, which is shown in FIG. 11 by the transistors connected to the respective
channel and the ground potential, these transistors The variable gain control 1NIII operates as
follows: each channel electrode of each transistor of channel 0 is ? 11 ? ? ?1? ? ? ? ??

movable! By adjusting the position of the lp @ child, it is possible to boost the eclipse of the gain
of each channel and place it at the center of the entire listener's voice, but the sum of the gains of
all rate channels is PIF! Keep it constant! Therefore, the user can not only balance or position
himself at the center of the sound quickly and easily within the area limited by the 41 @ speaker,
but also emits from the 4 L speakers The resulting relative total volume can be kept constant
throughout the balance of the acoustic system.
The present invention is described with reference to FIG. Figure 1 shows a multi-track magnetic
napper indicated generally at 10 by an appropriate bracket for the roto-tape player 10)) as
shown in the figure so that the car can be easily operated by the car 0J111. 1A7-?1 "Set it to-0,

When the cartridge is inserted into the playero 0 by providing an inlet 4 for inserting the
cartridge 1 into the playero 0, the player is automatically turned off and the player is
automatically cut off by making the cartridge 1 into at least a non-locking hook. Let's go. The
cartridge lIK contains one program, each program contains one independent signal ? lIOindependent channels. l Tratta napp can be inserted. If the cartridge is of this type, it can be
identified by a notch lla or a strike or something else, a single 4 FwI cartridge, a balanced Ada 7
controller, and a single independent cartridge. Sound-channel tube control can be performed. In
the recording of the independent channel ts of the referee of the audio signal information by the
tape player 10K, the sound-information 11 of each channel is in this case another speaker XI, ff,

resistance cost factor is configured with a balance control function and a voltage divider j, and
one end is a first channel and a first channel 36, and the ffKa end is a first channel and a third
channel. Connect to The movable contact of the voltage divider j can be easily adjusted across the

In this way, it is possible to balance the channels of each coffin and at the same time maintain the
