Protection
The amplifier protection:
•
is short-circuit proof
•
has over current limiting
•
Has gradual power limiting if amplifier
becomes too hot
•
will cut out if a continuous DC offset
appears on output
•
will cut out if output current exceeds 12
A
average continuously over a period of a
few minutes
•
is protected against most input overloads
The power supply protection:
•
will cut out if most common faults are
detected in the power supply (such as
over-voltage, master clock at incorrect
frequency, excessive temperatures)
•
is protected against most mains
transients
Components
(Footnote 4)
For reliability, all semiconductors are at least
industrial grade. All electrolytics are rated to
105
°
C.
•
only highly linear resistors and
MKP10/FKP1 capacitors are employed in
the critical audio path
•
six-layer PCBs are used in the power
amplifier to minimize stray magnetic fields
and to accurately define voltages
•
four-layer PCBs are used in the power
supply to minimize E.M.I. and voltage
transients, which improves reliability and
power efficiency
Compartments
There are four heavily shielded compartments:
•
a power supply unit
•
an input amplifier section
•
a power amplifier compartment
•
an output filter compartment
Filtering
Series and common mode EMI filtering is
present:
•
on the mains input
•
between the amplifier and power supply
High frequency filtering is present at the inputs
and output.

Footnotes
1.
THD specifications of our typical best
competitors are 200,000 parts per billion.

"Industrial" grade is a higher grade than
the "commercial" grade used by most
manufacturers.
