BRUEL & KJAER 2706 - Introduction

1. INTRODUCTION
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 full rating.
Power capacity
of Type 2706 is 75 VA into a 3 n 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.
