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.
