Front Panel Features
Overview
Your Cinema Grand AmpliÞ er has
seven chan nels of power ampliÞ 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 preampliÞ er
and ampliÞ 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 airß ow under the ampli-
Þ er. It prevents any carpeting from
restricting the airß 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 inß 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 SunÞ re equipment.
Feel free to choose the setting that
suits you.
