Introduction
QSA
®
stands for Quiet Sound Amplifier. The QSA
is a personal sound amplifier that automatically
enhances soft sounds. Loud sounds pass through
as though nothing is in the ears.
The QSA device provides the highest fidelity sound
amplification available at any cost. The sound
quality of QSA devices is superior to that of all
known custom-fitted devices, and is available
without medical referral or prescription.
The circuitry in QSA devices 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 QSA devices.
