The procedure of high and low bass or lowering of this circuit and the volume adjustment are similar to the previous circuit. The volume adjustment part connects the reference potentials of pin 4 and pin 2, so the pitch of pin 3 and pin 6 are reduced to different degrees. If a network with the same frequency is connected between feet 3 and 6, you can get different output signals with different volume levels at the sleeve head. This signal can control the audio equipment of the left and right channels respectively.
YJVFT series mine explosion-proof and intrinsically safe high-voltage VFD Motor is a highly integrated product of motor and variable frequency integrated machine. The Inverter Motor is applicable to belt conveyors, transfer machines, scraper conveyors, emulsion pumping stations and other coal mines that match the motor and the size of the connection. The Integral Drive Systems can realize the device's heavy-duty soft start, dynamic speed control and other functions.
