Front Panel Features

Overview

Your Cinema Grand AmpliÞ er has

Þ ve 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~Þ ve and 380
Joules for the 200~Þ ve. 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 ampliÞ er.
It prevents the carpet 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.
