INTRODUCTION
Getting to know your Dreadnaught D
This Dreadnaught D has been put through a rigorous and unique testing procedure that ensures that it will
last for many years with minimal service requirements. This procedure includes the following:
•
All assembled circuit boards are given a thorough visual inspection and are then tested in a bench-
reference Dreadnaught D.
•
The tested, assembled circuit boards are then installed in a new Dreadnaught D and the whole unit
is tested for every function and parameter.
•
The unit is put on a burn-in torture rack to test for any possible component failures.
•
It is then tested on an audio analyzer for all pertinent parameters.
•
The unit has all remaining chassis components installed and then undergoes a complete visual
inspection, which assures that all Dreadnaught D’s meet visual specifications.
•
The Dreadnaught D then undergoes a critical listening and functional test.
Burn-In Time
While the Dreadnaught D amplifier will sound wonderful without any burn-in time, users may experience
small sonic improvements during the first week or so of operation.
Reference Manual Conventions
For clarity purposes, references to buttons and LED’s will be shown in bold capital letters.
