What is a Transformer
Attenuator?
A Transformer Attenuator
is device used to control the sound output of an individual
speaker, in a 25V or 70V commercial sound system.
An Attenuator allows the operator to vary the signal
level from the audio source to each individually controlled
speaker as desired.
