DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a channel divider for dividing a tone signal into a number of periods IIIL to form a multiamplifier, multi-speaker system. In general, in the case of forming a multi-amplifier, multi-scan
system, a channel divider is connected to the output of the crypt amplifier to perform band
division. However, when driving with another full-range speaker set or a speaker set within
another network, the output of the channel divider is already divided into a specific number of 'tL
number bands, so its S degree You can not change the pillow. In order to correct such
inconveniences, a manual bus switch is provided in the channel divider sect, so that the input
signal from the input channel can be connected to the bass channel output channel if it is IpH.
This is a second class that can be used for R as well for full band reproduction. However, if the
power switch and the pass switch are set to the channel divider in this manner, for example, a
bus switch can be used to set the power supply even if the channel divider's ability to cure is
unnecessary. Although it is difficult to use a channel divider or a channel divider, it may cause
one use due to misunderstanding such as misfortune that has been lost in the multichannel
system. The present invention is intended to solve the above-mentioned inconveniences in the
conventional Nayan technology, and the following description will be made in the water 0, that is,
the drawing is the invention of Jin. An example of this is shown in the pro 7 diagram, 1 is the
input end of the audio note, 2 is the 1M buffer amplifier applied to this human power unit, and
the buffers of 3-1 to 3-411C. Is a plurality of filters connected in parallel to the output terminal
of the amplifier 2, and ? is from above to и и и и и I filter, middle am banded bass film, middle low
band bandpassed film, low pass filter, etc. I'm talking about 11 J minutes. The reference
numerals 4-1 to 4-4 are output ends which ltd the valley filter power of the above-mentioned
band pass filter and also reduce the force of the valley filter. The SW2 is a power switch with a
slide operation knob (not shown) for the IIII of this cha / non-refuse divider set, and the power
switch is turned on. The power supply 1 is applied to the direct current operation power supply
5 or the buffer ansis 2 or the like.
When the power switch S town is turned on, the master C detection circuit 6 whose IILM3 is
turned on is activated to detect the presence of the mu C power source and start the timing
circuit 1. The timing circuit 1 has a function of turning on the relay drive circuit 8 after a lapse of
time of about 3 to 5 seconds after receiving the excitation 11 signal from the circuit C feed
circuit 6, and thus the power switch After turning on the switch SWt, the relay drive circuit 8 is
turned on in 3 to 5 seconds to energize the relay 9. The relay 9 is provided with interlock
switches SW1-turtle to at, -a, and in the relay 3 activation state, each switch is connected to the
contact point f11111 and thus the input end 1 is provided. The added signal is applied to the
valley filters 3-1 to 3-4 through the buffer amplifier 2, and the band-divided field power is
provided to the output layers 4-1 to 4-4. Also, the power switch 5 (the relay drive Ji! ??? ??
Since the circuit 8 is also turned off, the relay 9 is de-energized, so that the switches BW, -a to
SW knee all switch to the contact giI, and the signal '? to 1 ░ I applied to the input end 1 is a
buffer angle 2 To the output end 4-4 of the low-pass channel via the bypass line 10 as it is. In
this case, the other output terminals 4-1 to 4-3 are shorted to the ground by the switches sw and
-b to SW1-a so that unnecessary signals are not output. 2 i mentioned above i + i! ???????
?????????? The circuit 1 may be omitted, and the relay drive (route) path 8 may be
directly connected to the detection detection circuit 6 so that the relay 9 is energized
simultaneously with the turning on of the power switch SW8. However, if configured in this way,
there will be 2 noises that cause noise 1 to m 4-1 to 4-4 due to 21i 1 good lumps when the
power is turned on. It is preferable to insert the p and p retiming circuit 7 in advance. ? As
apparent from the explanation of the kidney and 7t or more, the channel divider of the present
invention operates a relay in conjunction with a power switch, and this relay causes the output
from each filter to be extracted or the input signal is one output end as it is Because it has been
switched to pass 5 to pass, it is possible to keep turning on the power 2 even though the function
of the channel divider is unnecessary, or the channel divider may not use ?. It is possible to
eliminate misuse that causes misunderstanding and the like of whether or not the pressure is
reduced by the multi-channel method.
