Front Panel Features
Overview
Your Cinema Grand Ampli
Þ
er
has
seven chan nels of power ampli
Þ
ca-
tion combined in one chassis for the
purpose of re pro duc ing music or video
soundtracks. It accepts line level
signals from a controlling preampli
Þ
er
and ampli
Þ
es them to a higher level,
suitable for driving powerful stereo
and Home Theater speak ers.
Meter
The front panel meter indicates the
total energy available from the track-
ing downconverter power supply. It is
cal i brat ed in Joules and will normally
indicate ap prox i mate ly 480 Joules
for the Signature 400~seven, and
400 Joules for the 200~seven. Note
that the needle does not move under
normal use.
Crystal Base
The glass base is intended to en-
sure proper air
ß
ow under the ampli-
Þ
er. It prevents any carpeting from
restricting the air
ß
ow.
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 at trac tive installa-
tion.
Illumination
The meter is illuminated by an
in can des cent lamp operating at a
very warm color tem per a ture. I have
been in
ß
uenced 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,” nor
with a cool to cold color temperature. I
hope you like my unusual meter light-
ing treatment.
A switch has been provided on the
un der side of the unit toward the front.
This switch gives you the ability to
dim the meter lamp to reduce distrac-
tions in a Home Theater environment.
I like the brighter of the two settings,
as it il lu mi nates the meter nicely and
matches my other Sun
Þ
re equipment.
Feel free to choose the setting that
suits you.
