causing injury to a person or damage to the unit. Mount the unit according to the manufacturer’s instructions with  
the suggested mounting accessory.  
4. WALL OR CEILING MOUNTING: Mount the unit to a wall or ceiling only in the manner recommended by the  
manufacturer.  
5. WATER AND MOISTURE: Do not use the unit near water (for example, near a swimming pool, bath tub, wash  
bowl, kitchen sink, or laundry tub) or in a damp environment (like a basement or outside in the rain).  
6. OBJECT AND LIQUID ENTRY: Do not push objects of any kind into the unit through openings as they could touch  
dangerous voltage points and short-out parts, possibly resulting in a fire or electric shock. Avoid spilling liquid of any  
kind on the unit. If water or any metal object (such as a paper clip, coin, or staple) accidentally falls inside the unit,  
disconnect it from the AC power source immediately and contact Cary Audio Design for further instructions.  
7. HEAT: Position the unit away from heat sources such as radiators, heat registers, stoves, or other units  
(including amplifiers) that produce heat.  
8. VENTILATION: Slots and openings in the cabinet create ventilation to protect the component from overheating.  
These openings on the top and bottom panels must remain unobstructed. Allow at least 6 inches (16cm) of clearance  
above the unit and an opening behind the unit for airflow. Do not place the unit on a  
bed, sofa, rug, built-in bookcase, or rack without adequate ventilation.  
9. GROUNDING OR POLARIZATION: As a safety feature, the unit may be equipped with a polarized alternating  
current line plug in which one blade is wider than the other. This plug will fit into the power outlet only one way. If  
you cannot insert the plug fully into the outlet, try reversing the plug. If the plug still will not fit, contact a licensed  
electrician to update your obsolete outlet. Do not defeat the safety purpose of the polarized plug.  
10. POWER SOURCES: Operate the unit only from the power source indicated on the marking label. If you are  
unsure of the type of power supplied to your home, consult your unit dealer or local power company.  
11. POWER CORD PROTECTION: Arrange power supply cords so that they do not suffer from foot traffic or pinching  
by items placed on or against them. Pay close attention to cords where plug enter the AC outlet and where they exit  
from the unit.  
12. LIGHTNING: For added protection during a lightning storm or when is the component is idle for long periods of  
time, unplug the unit from the wall outlet and disconnect the antenna or cable system. This will help protect the  
unit from lightning and power line surge damage.  
13. POWER LINES: Do not locate an outside antenna system in the vicinity of overhead power lines or other electric  
light or power circuits. When installing an outside antenna system, take extreme care to avoid touching the power  
lines or circuits; contact with them could be fatal.  
14. OVERLOADING: Do not overload wall outlets, extension cords, or integral convenience receptacles as this  
increases the risk of fire or electric shock  
15. REPLACEMENT PARTS: When replacement parts are required, be sure the service technician has used replacement  
parts specified by the manufacturer or those having the same characteristics as the original parts. Unauthorized  
substitutions may result in fire, electric shock or other hazards.  
16. SAFETY CHECK: Upon completion of any service or repairs to the unit, ask the service technician to perform safety  
checks to ensure the unit is in proper operating condition.

INTRODUCTION  
Congratulations!  
You have purchased one of the most exotic integrated stereo audio amplifiers available. Within its power  
range, the SLI 80 displays the operating characteristics of a true "high-end" amplifier. Careful design,  
parts selection and proper circuit topologies contribute to incredible reliability and enjoyment.  
For the technically minded, a review of the circuit in your new SLI 80 is in order. Your new SLI 80  
integrated stereo amplifier operates in a class A/B-1 mode utilizing a negative fixed bias supply. The KT-  
88/6550 output tubes are configured in push-pull. The triode mode provides 40 watts/channel of output  
audio power and switching to the ultra-linear mode yields 80 watts/channel of output power. In the  
opinion of the designer the triode mode sounds the best.  
The output transformers in your SLI 80 are the most important component in the amplifier and have  
been specifically designed by Cary Audio Design for use in the SLI 80. Negative feedback is derived from  
a separate winding on the output transformer. This feedback winding and circuitry is used to reduce the  
noise floor and improve the speaker damping characteristics. Only 4 dB of feedback is utilized. The phase  
inverter is a self-balancing split load configuration utilizing the 6SN7 octal base dual triode. The  
preamplifier circuit is a resistive coupled Class A triode voltage amplification stage. The power supply in  
the SLI 80 features a 200% duty cycle EI laminate power transformer.  
The high voltage section features full wave vacuum tube (CV-729/5U4) rectification (not cheap voltage  
doublers used in many amplifiers) to a PI-L capacitive network. The input signal from the volume control  
is direct coupled (DC) to the first grid of the 6922. There are no coupling capacitors in line with the input  
signal on the SLI 80. The sub-woofer output is derived from a voltage divider network on the input stage  
of the SLI 80.  
A great deal of attention during design of your new SLI 80 was concentrated on the "overload recovery"  
ability of the amplifier. The ability of an amplifier to instantly recover from clipping is much more  
important than is commonly believed. In the power war of amplifier manufactures the mentality is  
focused on high and then even higher power output to solve the clipping problem. When in reality the  
most critical aspect is how fast a recovery an amplifier can achieve after overload. Most of the music  
being listened to in an average listening room is only requiring about 3 watts of power. It is on the  
transients of loud low frequency program material that tremendous signal voltages will appear at the  
input of the amplifier. It is in this situation that the overload recovery ability of an amplifier is of critical  
concern. The SLI 80 will overload symmetrically at any frequency in the audio band-pass. The SLI 80 will  
also yield faithful reproduction of extremely low frequencies at full output levels. Power transformer,  
power supply regulation and output transformer design and careful shaping of the overall frequency  
response curve all play a very important part in the ability of the SLI 80 to recover quickly when  
overloaded. The high voltage rail will fluctuate no more than a volt between soft and loud passages.  
Another technical feature of your new SLI 80, aside from how compact and gorgeous it looks, is the  
delightful, sensual beauty of the music it recreates. The first thing that will strike you about the SLI 80  
integrated amplifier is the incredible transparency and resolution of detail in the music. The SLI 80's  
sensual nature is best revealed in the sense of life it displays in female vocalists.  
The SLI 80 integrated presents music with such presence and directness, you'll be drawn into the music  
hour after musically satisfying hour. This is the result of circuit techniques, which eliminate any  
discernible crossover notch at low levels, and also contributes to the freedom from listening fatigue. The  
SLI 80 will draw you in even further as you realize how lucid and utterly uncolored neutrality reveals  
delicate nuances in the sound stage.  
Enjoy the music and of course please read this complete manual for a complete understanding of trouble  
free operation.

INSTALLATION  
This section describes the unpacking and installation procedures for your new component.  
Unpacking  
All Cary Audio Design shipping containers have been specially designed to protect their contents and  
special care has been taken to prevent damage under normal shipping conditions. Mishandling should be  
evident upon inspection of the shipping container. If shipping damage is found after visual inspection,  
take care not to destroy the evidence. If necessary, document the damage with photographs and contact  
the transport carrier immediately.  
Carefully remove your new component from its packing carton and examine it closely for signs of  
shipping damage. We strongly recommend saving all original packing cartons to protect your amplifier  
from damage should you wish to store it or ship it for after-sales service.  
Warranty Card  
IN THE USA: If you are the original purchaser of a new unit from an AUTHORIZED CARY AUDIO  
DESIGN DEALER, please fill out the enclosed warranty registration card and return it to Cary Audio  
Design within 15 days of your purchase. Cary Audio Design also suggests that you keep your original  
packing cartons in case you ever need to ship the unit when moving to a new home. Warranty  
restrictions apply. Consult the warranty section at the end of this manual for details. Please be certain to  
keep a copy of the original sales receipt from your AUTHORIZED CARY AUDIO DESIGN DEALER to  
validate the warranty if ever needed. The warranty is for the original purchaser only and does not  
transfer to any subsequent owner.  
OUTSIDE THE USA: Your local Authorized Cary Audio Design Distributor will make his own warranty  
policy for your country. Please check with them for the terms of warranty for your new amplifier.  
Placement  
In general, the location of your new SLI 80 is not critical. Certain precautions must be taken to ensure  
optimum performance. Avoid extremely hot locations such as near radiators or other heating units. Keep  
the top of the SLI 80 clear of books, paper or other equipment to protect against overheating! DO NOT  
place your SLI 80 in a closed bookcase - overheating will damage the amplifier! Allow 8 to 10 inches  
above the unit for proper ventilation.  
Power Requirements  
The SLI 80 is designed to operate from house current mains. The design voltage is 117 VAC at 50/60Hz.  
(Foreign units 234 VAC at 50/60Hz.)  
Cables  
The speaker cables from the output posts of the SLI 80 to the speaker system can be any convenient  
length your set-up requires. Select speaker cables of sufficient size to preserve the outstanding  
performance capabilities of your SLI 80. Heavy gauge #16 wire is suitable for distances up to 10 feet;  
#12 for 25 feet. Most audio dealers will have proper speaker cable in stock for this purpose.

OPERATION  
Signal input connection is made via the input jacks on the rear of the SLI 80 located on the rear panel.  
The interconnect cables from the output of the CD player, tuner, etc. can be any convenient length your  
set-up requires. The choice of a high quality interconnect cable is important. Once again, your audio  
dealer will have the proper cables in stock for this purpose.  
Your new SLI 80 is ready for operation after the speaker and interconnect cables have been installed.  
(Refer to the tube placement sheet in Charts and Drawings for proper installation)  
4/8 OHM Switch  
Select the proper impedance that is called for in you speaker specification. Make sure that both left and  
right channels are the same. An improper setting may not yield peak performance. Listen carefully to  
each setting and choose the setting that matches your speakers best.  
AC Off/Operate Switch  
Simply turn the rotary switch to the "operate" position. Observe that all 10 tubes are lit (filaments).  
Headphone/Output Switch  
Make this selection based on which output you want to use. If you are using headphones it would be best  
to have the headphones installed before switching to headphones. If the music is playing loud and you  
switch to headphones without headphones in place it may damage the unit.  
Break-In Period  
The tubes, capacitors and output transformers take approximately 100 hours of music playing to fully  
settle in for peak performance. The SLI 80 will sound good from the start and after the first couple of  
hours you will notice increased depth and tighter bass. This break-in period defies all engineering theory,  
but is true with high performance vacuum tube audio amplifiers.  
Bias Measurement  
The bias is factory preset. It is a good idea to measure it during the initial setup to make sure it is set to  
the specifications provided at the end of this manual. The AC voltage may be different from one area to  
the next. Follow the instructions provided. You will need a meter that allows you to read up to 100mA.  
WARNING  
MAKE SURE AMPLIFIER IS UNPLUGGED FROM AC MAINS BEFORE  
SERVICING.

SERVICE AND CARE  
The chassis may be cleaned with a soft towel and Windex® or a similar window cleaner. Spray it on the  
cleaning cloth to moisten it, not on the component. Do not use solvents or harsh chemicals to clean the  
preamplifier. They may remove the labels from the chassis. The frequency and need of cleaning will be  
governed by operating environmental conditions. Avoid letting the component become dusty or wet. A  
‘feather duster’ type cleaner will also work well for cleaning the component.  
Tube Replacement  
If it becomes necessary to replace the tubes in the SLI 80 amplifier, a matched quartet set of output  
tubes of the same brand should be used. A new tube kit is available from Cary Audio Design. You should  
get a few years or more from the output tubes with everyday usage and many, many years of use from  
the 6922 & 6SN7 input tubes.

LIMITED WARRANTY  
How State Law Relates to the Warranty  
Some states do not allow limitations on how long an implied warranty lasts and/or do not allow the  
exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions  
may not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights which vary from  
state to state.  
International Purchasers (Export Markets)  
Cary Audio warrants its merchandise to purchasers within the United States exclusively for use  
within the United States. It provides no other warranties, expressed or implied. If you are living  
outside of the United States, please consult your local dealer or distributor to determine the details  
of your local warranty.
