CHAPTER 1 Introduction Bob Carver, AmpliÞer Designer, Physicist Dear Friend: Thank you for purchasing my SunÞre Cinema Grand Þve channel power ampliÞer. I hope you enjoy it and the music it makes as much as I have enjoyed creating it for you. This magniÞcent ampliÞer represents my very latest thinking - and my best ampliÞer design ever. I’ve spent over twenty years developing it, and cannot imagine how I could make it any better, or reÞne it any further.
CHAPTER 1 Cinema Grand Editions The Cinema Grand Þve channel power ampliÞer is available in two editions: • Signature 400~Þve • 200~Þve The Signature 400~Þve has twice the power output, and uses heavier output terminals compared to the 200~Þve. Each Signature 400~Þve is personally signed on the front panel by Bob Carver. This manual uses illustrations of the Signature 400~Þve. The operational details, features, and connections to loudspeakers and preampliÞers are the same for both models.
CHAPTER 1 Unpacking Installation Your SunÞre AmpliÞer should reach you in perfect condition. If you do notice any shipping damage, please contact your SunÞre Dealer immediately. Read and follow all safety instructions shown on pages 2 and 3. Gently lift out the unit and remove all the packing material and accessories. It is important to save all the packing materials and the box in case your ampliÞer ever needs to be moved or shipped for repair. Make sure that you keep your sales receipt.

CHAPTER 1 Rear Panel Features 1 2 3 4 5 6 5 7 6 7 6 5 6 Sunfire Corporation Cinema Grand Signature 400 ~ five 1. AUTO/ON/OFF Switch 2. 12 VDC Trigger Input Your Cinema Grand AmpliÞer is designed with an automatic on/off circuit. Although the AUTO-ON signal sensing turn-on is adequate for most installations, the 12 VDC trigger inputs are offered as an optional way to turn on the ampliÞer.
CHAPTER 1 4. XLR Inputs If your preampliÞer has XLR outputs, connect them to these XLR inputs. Use them instead of the RCA inputs because balanced connections offer superior noise rejection. The female XLR inputs are wired as follows: Pin 1 is ground Pin 2 is positive (hot) Pin 3 is negative (cold) Balanced connections pass the input signal along two conductors. If there is any external noise and interference passing into the audio lines, both conductors will receive the same amount of noise.
CHAPTER 2 System ConÞgurations The following pages show some typical connections that you might make in your installation. They show how the inputs and outputs of the Cinema Grand AmpliÞer are connected to your preampliÞer and speakers.
CHAPTER 2 Balanced Connections If your preampliÞer has XLR outputs, it can be connected to the XLR inputs as shown. This example shows the connections to the SunÞre Theater Grand IV processor.
CHAPTER 2 Biamping If your speakers can be biamped, the Cinema Grand AmpliÞer can be conÞgured to provide a very powerful stereo system. The following connections are shown in the diagram on the next page. Output connections • Connect the ampliÞer’s right rear output to the right speaker’s woofer input terminals and connect the ampliÞer’s right front current source output to the right speaker’s upper range input terminals. If you prefer, you could use the right front voltage source instead.
CHAPTER 2 Biamping Connections Note: The remaining center channel can be used to drive a center speaker, or left unconnected.
CHAPTER 2 Biwiring Connections If your speakers can be biwired or biamped, they will have completely separate input terminals for the woofer section and the upper range. See the speaker diagram and discussion on page 12. UNBALANC ED PREAMP O U TPUTS R L Make sure that any links between the woofer and upper range posts are removed from the speakers when you want to biamp or biwire them. Consult your speaker owner’s manual for details.
APPENDIX Series and Parallel speaker connections The connection of more than one speaker per channel will tend to degrade the speaker’s frequency response, and may make the ampliÞer run hot. For the best results use one speaker per channel. Parallel For example, if you want to parallelconnect two speakers to the front right channel of the ampliÞer: If you do want to connect more than one speaker per channel, there are two main ways: Series or Parallel.
APPENDIX Troubleshooting Guide The SunÞre AmpliÞer is expertly designed and built to provide years of trouble-free performance. Most problems that occur can usually be solved by checking your setup or making sure that the audio and video components connected to the processor are on and fully operational. The following information will help you deal with common setup problems you may experience during normal use of your unit. If the problems still persist, please contact your SunÞre Dealer for assistance.
APPENDIX • Check that the interconnect cables to the ampliÞer do not have any broken connections. • If you are still having a problem, remember that SunÞre’s dealers and technical support staff will assist you. Other causes of noise • Speaker noise may also be caused by interference or noise on your AC line. Make sure there are no large appliances sharing the line, or halogen lamps or lamps with dimmer controls. • Try connecting your system to another AC socket on a separate line.
