Overview

Your Cinema Grand AmpliÞer has Þve channels of power ampliÞca- tion combined in one chassis for the purpose of reproducing music or video soundtracks. It accepts line level signals from a controlling preampliÞer and ampliÞes 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 track- ing downconverter power supply. It is calibrated in Joules and will normally indicate approximately 480 Joules for the Signature 400~Þve and 380 Joules for the 200~Þve. Note that the needle does not move under normal use.

Crystal Base

The glass base is intended to en- sure proper airßow under the ampliÞer. It prevents the carpet from restricting the airßow.

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 installa- tion.

Illumination

The meter is illuminated by an incandescent lamp operating at a very warm color temperature. I have been inßuenced 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 underside 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 illuminates the meter nicely and matches my other SunÞre equipment. Feel free to choose the setting that suits you.
