Rek RK1212BL 20W sweeping frequency signal generator

General description.

 

RK1212 Series Audio Sweep Signal Generator have been used an advanced press-controlled oscillator circuit. It can produce stable, low-distortion sine wave signal. It is digital display for the output amplitude and frequency. The Sweep range ≥1:1000 ,you can set the  sweep start and the end arbitrarily. The Max power: BL type≥20W,D type≥40W,E type≥60W,F type≥80W,G type≥100W. This equipment also has the function of the boot delay output, short circuit protection. It can be used to test the "positive" "negative" polarity function for all types of speakers, headphones, Dynamic receiver. Easy to operate, widely used in acoustics, telecommunications, etc., especially suitable for the production and sound box speaker manufacture. This instrument not only can be used for the audio testing because it can generate audio signal, but also can quickly determine the positive and negative polarity and the pure tone targets of speakers.
