Information

The Power Amplifier Type 2706 has been designed to drive small vibration exciters, particularly the B & K Vibration Exciter Type 4809. By switching to the 1.8 Amp. RMS output current limit, it is possible to drive the Mini Shaker Type 4810 safely at fu(I rating. Power capacity of Type 2706 is 75 VA into a 3 0, load. The overall votage gain is 40 dB, and input attenuators allow to adjust the level at a desired value when no level adjustment is available on the signal source, which makes it ideal for use with the Reverberation Processor Type 4422. Its very low harmonic distortion and low noise level make it suitable for a wide range of applications in vibration and acoustics. Type 2706 is fully protected against short circuited output and excessive heat sink temperature. When clipping of the output level occurs, a warning lamp is lit.
