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.
