Cary Cinema Power Amplifiers
Congratulations! You have just purchased one of the finest solid state power amplifiers made.
Whether two, three or five channels, your Cinema power amplifier is the perfect foundation
for your home stereo or theater system. In addition to the awesome power, the Cinema
power amplifier delivers flawless reproduction of musical detail and subtle special effects.
Cary Cinema power amplifier features include:
•Remote trigger (works with + 4.2 to + 32 Volts DC, see page 5)
•Short circuit protection,
•Thermal Protection circuits,
•DC offset protection,
•Matched Sanken, 50 Mhz multiple emitter output transistors.
•Soft start circuit prevents “Brown outs” when amplifier is turned on.
For the technically inclined, the following is an overview of the design characteristics of the
amplifier:
The input of the amplifier is fed into a high quality Burr-Brown op-amp for Balanced to Single-
Ended conversion. This input circuit is connected to a constant current source, differential
style with a current mirror. The pre-drive circuit is constant current Single-Ended Class A.
The output is a follower stage that uses special “designed for audio” high speed power
transistors that have excellent linearity characteristics. The power supply consists of a 700 or
1400 VA toroidal power transformer and either two or four 33,000uF/80V electrolytic
capacitors. Special attention was paid to circuit stabilization and speed of the amplifier to
reduce transient inter-modulation (TIM) distortion.
The Cinema power amplifier has three protection circuits to prevent damage to your speaker
and the power amplifier.
•AC Fuse - Fused with a 3.5A/7.5A for 240V and a 7.5A/15A for 120V.
•Thermal protection - if a channel overheats its output is disconnected until it cools down
to a safe operating temperature.
•DC offset sensor - If an amplifier malfunction or signal source malfunction occurs, the
potential exists for providing DC voltage to the loudspeaker. If this happens, the channel
will automatically shut down. No damage can occur.
In building the Cinema power amplifiers significant effort has been focused on building an
amplifier that delivers outstanding mechanical performance, is easy to use, and has sonic
properties that will delight the most demanding customer. Thank you for choosing Cary
Cinema Design and enjoy your new Cary Cinema power amplifier.
* Short circuit protection activates if load impedance is about 1.6 ohms or less. Constant tripping of short circuit
can degrade output transistors. To reset protection, turn the amplifier off, wait 10 seconds, then turn the
amplifier on.

INSTALLATION
This section describes the unpacking and installation procedures for your Cinema power
amplifier.
2.1 Unpacking
All 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 Cinema power amplifier 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.
2.2 Warranty Card
If you were the original purchaser of this unit and you purchased it in the United States, you should 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 of this manual for details. Please be certain to keep a copy of the original sales receipt from your
Authorized Cary Cinema dealer.
2.3 Cinema Amplifier Placement
The Cinema power amplifier is designed for use inside climate controlled rooms. It must be protected
from the elements and temperature extremes. For example, avoid placing the unit in extremely hot
locations such as near radiators or other heating units. Avoid installation where it might be damp or
wet to avoid potential shock hazards.
2.4 Power Requirements
The Cinema Amplifier is designed to operate from residential or commercial AC current mains. The
design voltage is 117 VAC at 50/60Hz (Foreign units 234 VAC at 50/60Hz).
2.5 Cables
The speaker cables from the output posts of the Cinema Amplifier to the speaker system can be any
convenient length, as your speaker set-up requires. Select speaker cables of sufficient size to preserve
the outstanding performance capabilities of your Cinema Amplifier. Heavy gauge #14 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. Consult your Authorized Cary Cinema dealer for advice.

6
2.6 Interconnects
Signal input connections are made via the input jack on the rear of the Cinema amplifier, either single-
ended or balanced. The interconnect cables from the output of the processor can be any convenient
length your installation 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.
WARNING: Do not touch the speaker output binding posts during
normal operation. You may be shocked. Do not short-circuit the speaker
output binding posts. Damage may occur or the fuse may blow. Do not
parallel or “bridge” the speaker output binding posts as this will damage
the amplifier.
OPERATION
Your new Cinema power amplifier is ready for operation after installing the AC power cord, speaker
and interconnect cables. Make sure the RCA/XLR switch is in the proper input selector position for
your particular installation.
3.1 On-Off Power Switch
Push the main power switch on the front panel to the “ON” position for normal use. (Set it to
OFF for remote turn on/off operation and it will be turned on and off by the trigger in the
surround sound processor.) LED’s 1-2, 1-3 or 1-5 will light up. At this point you can play music
or start the movie. Flip the main power switch to OFF for normal shut down.
3.2 Break In Period
The transistors and capacitors take approximately 100 hours of music playing to fully settle in for peak
performance. The Cinema power amplifier will sound good right out of the box and continue to
improve as it goes through ‘break in.’ After the first couple of hours you will notice increased depth and
tighter bass.
SERVICE AND CARE
The Cinema power amplifier 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 amplifier. Do not use solvents
or harsh chemicals to clean the amplifier. They may remove the labels from the chassis. The frequency
and need of cleaning will be governed by operating environmental conditions. Avoid letting it become
dusty or wet. A ‘feather duster’ type cleaner will also work well for cleaning the amplifier.
4.1 Factory Service
