VCA-100(WALL VOLUME CONTROLLER)
impedance of C2~G and C1 ~ G is 0Ω, and C2 ~
V2 and C1 ~ V1 become 10kΩ.
If the volume is set to minimum by turning the
volume control completely counter-clock wise, the
impedance of C2 ~ G and C1 ~ G is 10kΩ, and C2
~ V2 and C1 ~ V1 become 0Ω.
※ Caution :
Unplug the main device in case the
VCA-100 is connected and disconnected to the
main device.
* VCA (Voltage Control Amplifier) function
VCA (Voltage Control Amplifier) is the circuit
whose volume is set by the voltage level of a
control signal, and allows controlling the remote
volume without noise by using the VCA control.
This is VCA controller which enables to operate the
remote volume control without any noise caused
by the connection wire through connecting the
main device adopting VCA control function with the
VCA control terminal of the VCA controller.
