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. No matter what, its perfor-  
mance is, at Þrst, somewhat difÞcult to believe.  
The Signature 400~Þve can produce 400 watts rms per channel into 8 ohms and 800 watts rms into 4 ohms.  
The 200~Þve can produce 200 watts rms per channel into 8 ohms, and 400 watts rms into 4 ohms.  
The big breakthrough feature of the Cinema Grand is its uncanny tracking downconverter, which uses 18 Herculean  
Mosfets in the Signature 400~Þve and 12 in the 200~Þve.  
The circuit boards are heavy glass epoxy, double sided, with a Faraday shield on the back side. All resistors in the sig-  
nal path are 1% tolerance, metal-Þlm. Critical capacitors are Þlm devices with high dielectric strength and ultra low absorp-  
tion characteristics. An enormous Cinema Grand power source built around a massive power transformer provides the  
ultimate muscle for limitless dynamics.  
I could go on and on, but here’s the best part: I’ve included two kinds of outputs on the front left, right, and center :  
(1) a standard voltage-source (i.e., near zero impedance) output for all typical applications and:  
(2) a higher-impedance current-source output, which many prefer for electrostatic, planar magnetic, or ribbon speak-  
ers. Or you can biwire your system with the voltage source driving the woofer(s) and the current source driving the  
upper part of the system. In many cases this provides by far the best possible interface between the ampliÞer and  
the speaker system.  
Whichever way you decide to hook up the SunÞre Cinema Grand, it will create a multilayered soundstage that is deep,  
wide, three-dimensional, and utterly believable. The optional current-source output can coax forth a sensuous, delicately  
detailed musical voice long associated with low-powered classic tube ampliÞers. (The current-source characteristic of  
vacuum tubes is the dominant factor in the soundstage delivery of classic tube ampliÞers.)

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 immedi-  
ately.  
Read and follow all safety instruc-  
tions shown on pages 2 and 3.  
Make sure that the power  
cords of all your components  
are attached to the same outlet  
or at least to the same circuit.  
This will reduce the possibility  
of a ground loop in the system.  
Observe the following precautions  
when choosing a location for your  
Cinema Grand AmpliÞer:  
Gently lift out the unit and remove  
all the packing material and acces-  
sories. 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.  
Protect it from prolonged  
exposure to direct sunlight and  
other direct sources of heat,  
such as heating vents and  
radiators.  
Make sure that the total cur-  
rent draw does not exceed  
the current rating of your AC  
outlet or power strip.  
Use the XLR inputs if your  
preampliÞer has XLR outputs.  
These balanced connections  
provide superior noise rejec-  
tion.  
Do not expose the unit to rain  
or moisture. If ßuid or a for-  
eign object should enter the  
unit, immediately turn off the  
power and contact your SunÞre  
Dealer.  
Make sure that you keep your sales  
receipt. It is the only way to establish  
the duration of your Limited Warranty  
and it may come in useful for insur-  
ance purposes.  
Whenever possible, keep the  
power cords away from the  
signal cables or speaker wires  
to prevent any hum or audio  
interference being heard in the  
speakers.  
Please take a moment to Þll out and  
mail the SunÞre Customer Response  
card. Also read the serial number lo-  
cated on the rear panel, or the under-  
side of the chassis, and record it here:  
Avoid excessive exposure to  
extreme cold or dust.  
Do not place heavy objects on  
top of the unit.  
Choose reliable hookup cables,  
also called patch cords or RCA  
cables. They should be fully  
shielded and as short as pos-  
sible for the job.  
Allow adequate ventilation  
around the ampliÞer; do not  
cover the ventilation slots.

AC Power Considerations  
Ensure that the unit is plugged into  
an outlet capable of supplying the cor-  
rect voltage speciÞed for your model.  
The outlet should be capable of sup-  
plying 15 amps for the 120 V model,  
8 amps for the 230 V model.  
Some patch cords can be a  
very tight Þt and there is usu-  
ally a preferred method of get-  
ting them off. Some have to be  
removed with a twisting action.  
Be gentle or you may damage  
the jacks of the ampliÞer or  
your other components.

Care  
If you need to clean the front sur-  
face, Þrst turn off the power and then  
use a dry soft cloth, rubbing with the  
grain. Be careful not to scratch the  
display window.  
Some special patch cords  
can only be hooked up in one  
direction, these are usually  
marked with arrows.  
It is usual for the right patch  
cord plugs to be red and the  
left connections to be white,  
grey or black. Video connec-  
tions are usually yellow.  
Connection Tips  
Before setting up your new system,  
please consider the following :  
Always make sure that your  
components are all turned  
OFF before making or  
changing connections.

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

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.  
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.  
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.

The voltage range for the trigger  
input is from 5 to 18 VDC. The input  
impedance is approximately 600  
(20 mA @ 12V).  
1. AUTO/ON/OFF Switch  
Your Cinema Grand AmpliÞer is  
designed with an automatic on/off  
circuit.  
2. 12 VDC Trigger Input  
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.  
3. RCA Inputs  
In the AUTO-ON position, the  
ampliÞer will automatically  
turn on if an audio signal is  
present at the right front or  
center inputs, or if it receives  
a 12 VDC input voltage at the  
trigger inputs. The ampliÞer  
will automatically turn off after  
a few seconds if the trigger  
voltage is removed, or after  
approximately 30 minutes in  
the absence of an audio signal.  
Your Cinema Grand AmpliÞer has  
three sets of inputs for each of the Þve  
channels. Two are unbalanced RCA  
inputs and one is a balanced XLR  
type.  
The SunÞre Theater Grand II, III  
and IV Processors have a compatible  
12 VDC trigger output (see page 11).  
This can be used to automatically turn  
on the Cinema Grand when the The-  
ater Grand Processor is turned on  
The two RCA inputs for each chan-  
nel are joined together internally, and  
either one can be connected to the  
corresponding output of your pream-  
pliÞer. The other can be used as a  
daisy-chaining output, sending the  
preampliÞer output signal to another  
channel or to another ampliÞer.  
1/8" mono mini jacks are provided  
for ease of installation, along with a  
terminal strip to allow more ßexibility

CHAPTER 1  
NOTE: The Current Source output  
is a Voltage Source modiÞed to yield  
a Current Source impedance of one  
ohm. This corresponds approximately  
to a vacuum tube ampliÞer output im-  
pedance and constitutes the dominant  
factor in the soundstage delivery of  
classic vacuum tube power ampliÞers.  
4. XLR Inputs  
5. Current Source Outputs  
and:  
6. Voltage Source Outputs  
The front left, front right, and center  
channels each have a Voltage Source  
output and a Current Source output.  
The Voltage Source output has a  
source impedance of approximately  
zero ohms. The Current Source has  
a source impedance of approximately  
one ohm. The left rear and right rear  
channels have Voltage Source out-  
puts only.  
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:  
7. Current Source Fuses  
Pin 1 is ground  
Each Current Source output has an  
in-line fuse to protect your speakers. If  
one ever opens, there will be no out-  
put to that speaker. Turn off the power  
if you ever have to change a fuse.  
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 inter-  
ference passing into the audio lines,  
both conductors will receive the same  
amount of noise. This noise is then  
rejected in the balanced input stage of  
the Cinema Grand AmpliÞer.  
The top post of each binding post  
pair is the positive output, and con-  
nects 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.  
8. IEC connector  
The ampliÞer comes with a detach-  
able Linecord which attaches here.  
Make sure it is Þrmly pushed in place.  
Connect the other end to an AC outlet  
which is properly conÞgured for the  
type of plug and has the correct volt-  
age for your model.

According to your musical taste,  
you may select the Current Source for

For cone based systems, use either.  
For a biwired system, use the Current  
Source for midrange and treble driv-  
ers, and use the Voltage Source for  
the subwoofer(s). These are sugges-  
tions only. By all means, please feel  
free to experiment with other wiring  
options.

The 12 VDC trigger connection  
shown can be used to turn the ampli-  
Þer on when the preampliÞer turns on.  
Alternatively, you could use the ampli-  
Þer's AUTO-ON switch. The ampliÞer  
will then automatically turn on when a  
preamp audio signal is received.

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 speak-  
er’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.  
Inputs  
Tweeter  
Connect the ampliÞer’s left  
rear output to the left speaker’s  
woofer input terminals and  
connect the ampliÞer’s left front  
current source output to the  
left speaker’s upper range in-  
put terminals. If you prefer, you  
could use the left front voltage  
source instead.  
Woofer  
A speaker which can be biamped or  
biwired will have two sets of binding  
posts. Sometimes these posts are  
joined with shorting links for normal  
operation.  
Input connections  
Each ampliÞer channel has two  
RCA inputs which are connected  
together internally.  
Make sure that any links are  
removed when you want to  
biamp or biwire the speak-  
ers. If not, this may cause  
damage to the ampliÞer.  
Connect the preamp stereo  
output to the front channel  
RCA jacks. Then install short  
interconnects from the other  
unused front RCA jacks across  
to the rear channel RCA jacks.  
In this way, the front and rear  
ampliÞer channels are fed with  
the same signal from your  
preamp.  
Each speaker can be driven by two  
ampliÞer channels, one to drive the  
woofer and one for the upper range.  
You will need to use four ampliÞer  
channels to run two speakers.  
If you use the Cinema Grand Ampli-  
Þer for biamping, then a total of three  
speakers can be connected. You will  
need an extra two channel ampliÞer if  
you want to run the surround speak-  
ers in a Home Theater system.  
Note: you cannot use XLR  
cables in, with RCA out, or  
RCA in with XLR out. There is  
no direct internal connection  
between the RCA and XLR  
inputs.

Biamping with an external  
crossover  
If you have an external active  
crossover, you can greatly increase  
the efÞciency of your system. The  
crossover will split the preampliÞer  
output signals into two frequency  
ranges.

The front channels of the Cinema  
Grand AmpliÞer each have two pairs  
of outputs which can be used to biwire  
your speakers. The idea is to use the  
voltage source to drive the woofer,  
and the current source to drive the  
upper range. This will offer improved  
performance and still allow you to  
connect Þve speakers for your home  
theater system.

shown above. Otherwise, connect it  
and the rear speakers as shown on  
pages 10 and 11.  
Input connections  
Connect your preampliÞer’s outputs  
to the ampliÞer’s corresponding input  
jacks. If your preampliÞer has XLR  
outputs, use these wherever possible.

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  
Parallel  
For example, if you want to parallel-  
connect two speakers to the front right  
Ideally, the total average  
impedance should be no less  
than 2 ohms per channel.  
channel of the ampliÞer:  
run hot. For the best results use one  
speaker per channel.  
You must make sure that the  
lower impedance does not  
cause the ampliÞer to over-  
heat, shut down, blow the line  
fuse, or pop your circuit break-  
er. If this happens, you should  
reduce the number of speakers  
wired in parallel, rewire them in  
series, or use more than one  
power ampliÞer.  
If you do want to connect more than  
one speaker per channel, there are  
two main ways: Series or Parallel.  
Amplifier  
Outputs  
Series  
For example, if you want to  
series-connect two speakers to the  
front right channel of the ampliÞer:  
The positive output terminal of  
the right channel connects to  
the positive input post of the  
Þrst speaker and to the positive  
post of the second speaker.  
Amplifier  
Outputs  
The negative output terminal  
of the right channel connects  
to the negative input post of  
the Þrst speaker and to the  
negative post of the second  
speaker.  
The positive output terminal of  
the right channel connects to  
the positive input post of the  
Þrst speaker.  
The total impedance of equal  
speakers in parallel is found  
by dividing the impedance of  
one speaker by the number of  
speakers. For example, two  
eight ohm speakers in parallel  
is a four ohm load (eight ohms  
divided by two), four eight ohm  
speakers in parallel is a two  
ohm load (eight ohms divided  
by four).  
The negative input post of the  
Þrst speaker connects to the  
positive input post of the sec-  
ond speaker.  
The negative input post of the  
second speaker connects to  
the negative output terminal of  
the right channel.  
The total impedance of speak-  
ers in series is found by adding  
their impedances together. For  
example, two four ohm speak-  
ers in series is an eight ohm  
load.  
Parallel connections are harder  
on the ampliÞer than series  
connections, as the total im-  
pedance is lower compared to  
driving a single speaker, and  
the ampliÞer must produce  
more current to drive them.  
Series connections are easier  
on the ampliÞer than parallel  
connections as the total imped-  
ance is higher than driving a  
single speaker.

APPENDIX  
Troubleshooting Guide  
The SunÞre AmpliÞer is expertly  
designed and built to provide years of  
trouble-free performance. Most prob-  
lems that occur can usually be solved  
by checking your setup or making  
sure that the audio and video compo-  
nents connected to the processor are  
on and fully operational.  
Try to have all of your equipment  
on the same electrical outlet or  
circuit. Group all the low power  
components (preamp, CD player,  
DVD etc.) on a single outlet or  
power strip. This is provided that  
the overall current draw from your  
equipment does not exceed the  
rating of the outlet or breaker.  
The ampliÞer shuts down  
often or the line fuse blows  
often  
Check that the positive and nega-  
tive speaker wires are not shorted  
together.  
Make sure that no speakers are  
shorted internally. If you have an  
ohm-meter, disconnect the speaker  
wires and measure the resistance  
between the speaker’s positive  
and negative terminals. If the read-  
ing is less than 2 ohms, the speak-  
ers may have an internal short.  
Measure all speakers and check  
their impedance speciÞcations.  
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.  
Disconnect all cables which come  
from outside the room, and check  
if the hum goes away. This in-  
cludes such connections as cable  
TV, satellite TV, or roof top an-  
tennas. Make sure that they are  
disconnected where they Þrst enter  
the room, so they are making no  
connection to the preampliÞer or  
the TV, or any other component. If  
the hum is caused by the cable TV  
line, then you will need a “ground  
loop isolator.” This is an inexpen-  
sive device Þtted in line with the  
coaxial cable feed. Contact your  
cable company or your SunÞre  
Dealer for assistance.  
No sound from one or  
more speakers  
Speaker cables may have come  
undone. Turn off your system and  
check the cables, and tighten the  
ampliÞer and speaker binding  
posts.  
If you have connected speakers  
in Parallel, the overall impedance  
may be too low. It is recommended  
that you rearrange the speakers  
in Series to increase the overall  
impedance, thus taking some of  
the load off the ampliÞer.  
Broken audio cable.  
The preampliÞer volume level is  
low for the channels concerned.  
Recheck the preampliÞer calibra-  
tion procedure.  
Make sure that the ampliÞer has  
good ventilation and is not over-  
heating. Use the crystal base to al-  
low good airßow underneath. If the  
ampliÞer is in a closed rack, open  
up the rear panel or use a quiet fan  
for improved ventilation.  
Disconnect all connections from  
the preampliÞer to your TV, VCR or  
DVD.  
The preampliÞer Mute switch is on,  
or an external processor loop or a  
tape monitor loop is engaged.  
As a test, disconnect any other  
component which has a grounded  
power cord.  
Check that your preampliÞer or  
source is running the correct sur-  
round sound mode. Maybe it is set  
for stereo when you were expect-  
ing 5.1 surround sound.  
A Hum is heard in your  
speakers  
This problem is more than likely  
caused by a “ground loop” in your sys-  
tem, rather than a fault in the ampliÞer.  
Follow these steps to isolate the main  
cause of the hum, there may even be  
more than one.  
NOTE: Never remove the ground pin  
from any power cords. This is very  
dangerous.  
If the hum persists, disconnect all  
the source components one at a  
time from the back of the preampli-  
Þer, until you identify the problem.  
Check in case any missing chan-  
nels have been turned off in a  
preampliÞer setup menu. For  
example, the center ampliÞer  
channel will not receive a signal  
if the preampliÞer has been set to  
"Phantom."  
Ground loop isolators are available  
for audio lines and video. You can  
ask your SunÞre Dealer for assis-  
tance.  
If your preampliÞer has XLR bal-  
anced outputs, use them because  
they offer greater immunity to  
noise Þelds.  
The Auto/on/off switch might be in  
the off position.  
Try moving the speaker cables  
away from any power cords. Try  
just one speaker, connecting it to  
each ampliÞer channel and see if  
one channel is bad.  
Remember to turn off all compo-  
nents in your system, including  
the ampliÞer, before disconnecting  
or connecting any cables during  
troubleshooting.  
One of the fuses for the current  
source outputs may have blown.

sist you. Make a list of the things  
you have tried.  
Poor bass performance  
If you are still having a problem,  
remember that SunÞre’s dealers  
and technical support staff will as-  
sist you.  
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.”  
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 an-  
other AC socket on a separate line.  
Check that the speaker wires have  
been connected correctly: Make  
sure that the positive of each  
speaker connects to a positive out-  
put of the ampliÞer, and the neg-  
ative of each speaker connects to  
a negative output. If one speaker is  
wired incorrectly, than it will be “out  
of phase” with the others, resulting  
in poor bass performance.  
Keep power cords away from au-  
dio cables.  
Do not place the preampliÞer di-  
rectly on top of the ampliÞer.  
If the hum is heard from within  
the ampliÞer and not through the  
speakers, this may also be caused  
by interference on the AC or DC  
lines. The power transformers  
may turn this interference into an  
audible noise. Internal hum can be  
made worse by a shelf or cabinet  
resonating, so try moving the am-  
pliÞer to another shelf.  
If you have connected the ampliÞer  
using the XLR inputs, make sure  
that the XLR cables are wired cor-  
rectly. If one has the hot and cold  
reversed, then this will also cause  
a speaker to be out of phase.  
Turn-on and turn-off  
thumps  
Try moving your preampliÞer  
further away from your ampliÞer.  
Sensitive preamp circuits may pick  
up hum from the ampliÞer trans-  
former’s magnetic Þeld.  
Plug the ampliÞer into an  
unswitched AC outlet, and use the  
AUTO-ON feature. This will allow  
the ampliÞer to turn on and off with  
good manners.  
Try moving your components further  
away from the TV, especially if  
you ever notice the screen has  
changed color in the area closest  
to the component.  
Current source outputs not  
working  
If you are biamping or biwiring,  
make sure that the current source  
fuses have not blown.  
If you have very high efÞciency  
speakers, these may show up  
noise which other speakers may  
not.  
If these fuses blow often, it is  
acceptable to replace with a slo-blo  
7 ampere fuse.  
If you are still having a problem,  
remember that SunÞre’s dealers  
and technical support staff will as-
