Mp-1212 series audio frequency sweep signal generator USES advanced voltage controlled oscillation circuit to produce stable and low distortion sine wave signal. Output amplitude and output frequency are displayed by digital tube. The sweep bit can reach more than 1:1000. The start point and end point of the sweep can be set arbitrarily between (20hz-20khz). (maximum output power: type B ≥20W, type D ≥40W, type E ≥60W, type F ≥80W, type G ≥100W). This machine also has the functions of starting up delay output, short circuit protection, etc., easy to operate, widely used in electroacoustic, telecommunications, etc., especially suitable for loudspeaker, earphone production and audio manufacturers.
