User's Manual Introduction Dear Friend: Bob Carver, Amplifier Designer, Physicist Thank you for purchasing my Sunfire Cinema Grand Signature Edition five channel power amplifier. I hope you enjoy it and the music it makes as much as I have enjoyed creating it for you. This magnificent amplifier represents my very latest thinking - and my best amplifier design ever I’ve spent over twenty years developing it, and cannot imagine how I could make it any better, or refine it any further.
User's Manual Unpacking Your Cinema Grand Amplifier should reach you in perfect condition. If you do notice any shipping damage, please contact your Sunfire Dealer immediately. Maximum output current 120 amperes peak to peak per channel Maximum output voltage 58 Vrms 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 amplifier ever needs to be moved or shipped for repair.
User's Manual Installation Read and follow all safety instructions shown on pages 2 and 3. Observe the following precautions when choosing a location for your Cinema Grand Amplifier: • Protect it from prolonged exposure to direct sunlight and other direct sources of heat, such as heating vents and radiators. • Do not expose the unit to rain or moisture. If fluid or a foreign object should enter the unit, immediately turn off the power and contact your Sunfire Dealer.
User's Manual Front Panel Features Overview Illumination Your Cinema Grand Amplifier has five channels of power amplification combined in one chassis for the purpose of reproducing music or video soundtracks. It accepts line level signals from a controlling preamplifier and amplifies them to a higher level, suitable for driving powerful stereo and home theater speakers. The meter is illuminated by an incandescent lamp operating at a very warm color temperature.
User's Manual Rear Panel Features 5 8 7 4 2 1 6 1. AUTO/ON/OFF Switch 3. XLR Inputs Your Cinema Grand Amplifier is designed with an automatic on/off circuit. If your preamplifier has XLR outputs, connect them to the XLR inputs. Use them instead of the RCA inputs because balanced connections offer superior noise rejection. • In the AUTO-ON position, the amplifier will automatically turn on if an audio signal is present at the left front or center inputs.
User's Manual The top post of each pair is the positive output, and connects to the positive (red) post of your speaker. The bottom post of each pair is the negative, and connects to the negative (black) post of your speaker. The posts can accept bare wire, spade terminals, and dual or single banana connectors. 6. Current Source Fuses Each current source output has an in-line fuse to protect your speakers. If one ever opens, there will be no output to that speaker. 7.
User's Manual System Configurations 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 Amplifier are connected to your preamplifier and speakers. RS + R + C + RS LOUDSPE AKERS If your preamplifier has RCA outputs, it can be connected to the amplifier inputs as shown. This diagram also shows how the voltage source outputs connect to the input posts of your front speakers.
User's Manual RS + R + C + RS LOUDSPE AKERS + L BALANCE PREAMP O D UTPUTS R C L LS + LS If your preamplifier has XLR outputs, it can be connected to the XLR inputs as shown. This diagram also shows the current source output connections to the front speaker inputs. (The voltage source outputs can be used instead, as shown on the previous page).
User's Manual Biamping If your speakers can be biamped, the Cinema Grand Amplifier can be configured to provide a very powerful stereo system. Inputs Output connections • Connect the amplifier’s right rear output to the right speaker’s woofer input terminals and connect the amplifier’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.

User's Manual Biwiring 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. 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.

If used, they can be connected as shown on pages 10 and 11.
User's Manual Speaker connections If your speakers cannot be biwired, the normal configuration is to have one speaker connected per channel. The connection of more than one per channel will tend to degrade the speaker’s frequency response. For the best results use one speaker per channel. If you want to connect more than one speaker per channel, there are two main ways: series or parallel.
User's Manual Troubleshooting The Sunfire Cinema Grand Amplifier 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 components connected to the amplifier 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 Sunfire Dealer for assistance.
User's Manual • Try moving the speaker cables away from any power cords. Try just one speaker, connecting it to different channels and see if an amplifier channel is bad. • Check that the speaker wires have been connected correctly: Make sure that the positive of each speaker connects to a positive output of the amplifier, and the negative of each speaker connects to a negative output.
