DPI SERIES USER MANUAL
1
Introduction
Thank you for choosing the Q4audio DPI series for your ap-
plication. You have made an excellent choice. DPI series is part
of a new breed of power ampliers using our proprietary switching
output stage, also called class D (CLD) topology.
The rugged steel chassis and conventional power supply
based on a low ux toroïdal transformer make it a perfect match
for applications where portability is not a premium requirement.
DPI incorporates unique features that require some study be-
fore being applied. One of these features is the EFL® (Extended
Feedback Loop) remote sensing technique. If you intend to use
this feature read the section on this subject carefully.
