Introduction

QSA

®

 stands for Quiet Sound Amplifier. The BEAN 

is a personal sound amplifier that automatically 

enhances soft sounds. Loud sounds pass through  

as though nothing is in the ears.

The BEAN provides the highest fidelity sound 

amplification available at any cost. The sound  

quality of the BEAN is superior to that of all  

known custom-fitted devices, and is available  

without medical referral or prescription.

The circuitry in the BEAN incorporates a patented  

new ultra-low-distortion output amplifier, along 

with all of the important features and benefits of the 

original K-AMP

®

 circuit first described over 30 years 

ago by Mead Killion, Ph.D., Sc.D.(hon), a well known 

engineer and professor of audiology. No circuitry, 

including digital technology, has proven superior to 

the sound quality of K-AMP circuitry – the engine 

of the BEAN.
