Overview
Your Sunfire Amplifier
is a two channel

chassis for the purpose of reproducing music
or video soundtracks. It accepts line level
signals from a controlling preamplifier and
amplifies them to a higher level, suitable for
driving powerful stereo and home theater
speakers.

Meter
The front panel meter indicates the total
energy available from the tracking
downconverter power supply. It is calibrated in
Joules and will normally indicate approxi-
mately 480 Joules for the Signature Edition
and 400 Joules for the Standard Edition. Note
that it does not move under normal use.

Crystal Base
The glass base is intended to ensure
proper airflow under the amplifier. A good
choice for the amp location is centered
between the loudspeakers on the floor, using
the glass base to prevent the carpet from
restricting the airflow. If you choose to place
the unit on a shelf or other hard surface, the
base will isolate the amp from vibration and
will help make an attractive installation.

Illumination
The meter is illuminated by an incandes-
cent lamp operating at a very warm color
temperature. I have been influenced by the
scale lighting of classic electronic equipment
from the 1950’s, with their warm dim glow,
usually with a “headlight effect” from the lamp.
I incorporated that historical look and feel into
this meter lighting. It is decidedly not “evenly
back-lit” with a cool to cold color temperature.
I hope you like my unusual meter lighting
treatment.

A switch has been provided on the
underside of the unit toward the front. This
switch gives you the ability to dim the meter
lamp to reduce distractions in a home theater
environment. I like the brighter of the two
settings, as it illuminates the meter nicely and
matches my other Sunfire equipment. Feel
free to choose the setting that suits you.
