CHAPTER 1 Introduction Bob Carver, AmpliÞer Designer, Physicist Dear Friend, Thank you for purchasing my SunÞre Cinema Grand seven 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 seven channel power ampliÞer is available in two editions: • Signature 400~seven • 200~seven The Signature 400~seven has twice the power output, and uses heavier output terminals compared to the 200~seven. Each Signature 400~seven is personally signed on the front panel by Bob Carver. This manual uses illustrations of the Signature 400~seven. 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 Front Panel Features Cinema Grand Power Supply Energy 100 2 00 300 400 500 0 JOULES Load Invariant High Fidelity Super Definition Power Amplifier Signature 400 ~ seven Sunfire Four Hundred Watts per Channel by Seven Channels Overview Meter Illumination Your Cinema Grand AmpliÞer has seven channels of power ampliÞcation combined in one chassis for the purpose of reproducing music or video soundtracks.
CHAPTER 1 Rear Panel Features 1 2 3 4 5 6 6 7 6 6 6 7 6 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. These balanced connections offer superior noise rejection compared to the unbalanced RCA inputs. 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. This also shows the Current Source output connections to the front left and right speaker inputs. (The Voltage Source outputs can be used instead, as shown on the previous page.
CHAPTER 2 Biamping If your speakers can be biamped, the Cinema Grand AmpliÞer can be conÞgured to provide a very powerful system. The following connections are shown in the diagram on the top half of the next page. Output connections • Connect the ampliÞer’s right rear output to the right speaker’s woofer input terminals. 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 UNBALANC ED PREAMP OU TPUTS R Line-level audio signals L From: PreampliÞer main RCA outputs To: AmpliÞer RCA inputs Line-level audio signals From: AmpliÞer Front L/R RCA To: AmpliÞer Rear L/R RCA inputs + - Note: The remaining channels can be used to drive other speakers, 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 OU 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 your 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. Poor bass performance • Make sure that your preamp does not have the bass level turned down. • Many surround preampliÞers have controls which can direct all the bass to subwoofers, or let your main speakers play the full range. Make sure that the preampliÞer has been correctly set. If you are not using a subwoofer, set the speaker options to “Large.
