INSTALLATION _____________________________________________________

This section describes the unpacking and installation procedures for your new component.

Unpacking

All Cary Audio Design shipping crates 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 component 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

The CAD 211 AE is designed for use in homes. 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. Its location among the user’s audio components is not critical; however, certain precautions must be taken. Avoid moisture, direct sunlight, and dusty areas.

Power Requirements

The CAD 211 AE is designed to operate from house current AC mains. The design voltage is 117 Volts AC at 50/60Hz (Foreign units 234 Volts AC at 50/60Hz).

Speaker Cables

The speaker cables from the output posts of the CAD 211 AE to the speaker system can be any length that your setup requires. Select speaker cables of sufficient size to preserve the outstanding performance capabilities and sound quality of your new power amplifiers.

Heavy duty #14 gauge wire is suitable for distances up to 15 feet; #10 gauge is good for 25-30 feet. Most audio dealers have high performance speaker cable in stock for this purpose. We strongly urge you to try several types to find the best ones for your combination of components and speakers.

6

Interconnect Cables

Signal input connection is made via the RCA input jack on the rear of the amplifier located next to the output binding posts. The input interconnect cables from the output of the preamplifier can be any length your installation requires. A shielded high quality interconnect cable is important to reduce chances for hum or interference. Ask your Authorized Cary Audio Design audio dealer for advice.

WARNING!

Page 10 shows correct tube placement positions, 300B tube bias settings and ‘Cat Eye’ tube brightness adjustment. Page 11 shows 300B tube pin configuration. FAILURE TO INSTALL THE

TUBES CORRECTLY WILL DAMAGE THE UNIT. Watch the tube pins carefully on the 300B tube during installation as it is possible to force the tube to plug in ‘wrong’ during installation. The

300B tube has no ‘safety key’ center pin on the tube to prevent incorrect installation. It has two large pins and two slightly smaller pins. Please look carefully at the tube pins and the tube socket holes to note the two different size connections prior to installation. Incorrectly plugging in the 300B driver tube will possibly damage the amplifier and is not covered by the manufacturer’s warranty.

OPERATION ________________________________________________________

Your new amplifier is ready for operation after the speaker cables, interconnect cables and the tubes have been installed.

On-Off Power Switch

Push the AC toggle switch toward the rear, to the “ON” position. The 6SN7 input tubes, 1629 Cat Eye tube and the 300B driver tube will light up in this setting.

Standby Toggle Switch

Push the toggle switch toward the rear of the unit to operate. The installed output tube will light up.

Break In Period

The tubes, capacitors and the output transformers take approximately 100 hours of music playing to fully settle in for peak performance. Small imperfections in the tube surfaces will ‘boil off’ during the break in period as well. The amplifier will sound good right out of the box but it will improve as break in occurs.

After the first couple of hours you will notice increased depth and tighter bass. This break in period is true with most high performance audio amplifiers.

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 as 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.

Replacing Vacuum Tubes

If it becomes necessary to replace the tubes, the same brand as installed new should be used. A complete new tube kit is available from Cary Audio Design. Although useful tube life varies depending on the nature and degree of use, under normal home use, the 845 or the 211 output tube and the 300B driver tube should last many years in the CAD 211. The 6SN7 input tubes should last even longer.

NOTE: Any current production or New Old Stock (NOS) types of 845, 6SN7 or 300B tubes will work fine in the CAD 211 Anniversary Edition amplifier. The voltages are fine for all available types.

WARNING

Make sure the amplifier is unplugged 30 minutes from the AC mains before replacing the tubes to avoid risk of shock and high heat from the 845 tube.

Factory Service

Careful consideration has been given to the design of this product to keep maintenance problems to a minimum. If problems arise, refer to the trouble-shooting guide at the end of this manual. If the problem is not easily solved, we suggest that you contact our Customer Service Department by phone at (919) 355-

0010, 1–5 pm Eastern Standard Time, to describe your problem in detail. Do not return the component to the factory without a Return Authorization Number (RA) from the Customer Service Department.

Cary Audio Design assumes no responsibility if the transportation company refuses to pay a damage claim due to your improper packing or lack of insurance should the unit be lost in shipment. We strongly suggest using the original packing cartons for shipping any Cary Audio Design component.

Non-Warranty Repairs

Cary Audio Design will provide repair service for its products charging on a time and expense basis. At this time, the standard non warranty service bench fee is $125 with all parts used for repair charged extra. This may change with time and is not a quote for service. Please call us at 919-355-0010 for more information about out of warranty service and repair fees.

WARNING

Make no attempt to put the CAD 211 in service outside of the cabinet or with the cabinet open! Contact with the high voltages found inside the unit can be fatal! Remove the AC power plug from the wall and allow 30 minutes for the high voltage capacitors to discharge through bleeder resistors before attempting to change the tubes or to clean the inside the amplifier.

8

CAUTION

Never remove or insert the AC plug when the unit is on or the AC power switch is in the “ON” position. Obstruction of the top portion of the amplifier will result in the tubes overheating.

Set the 845 tube bias to 100 mA DC

Current

Insert the ¼” bias meter plug into the bias jack on the back of the amplifier chassis. Connect the bias cable red alligator clip to the positive (+) connection on your meter. Connect the bias cable black alligator clip to the negative (-) connection on your meter. Check the 845 tube bias current reading and adjust for a

100 mA reading on the Volt Ohm Meter (VOM) or DC current meter if the reading is different than 100 mA DC current. Check and readjust to 100 mA again after the CAD 211 amplifier is warmed up for 10 minutes. Remove the ¼” plug from the bias jack and enjoy the music!

Note: Bias is factory preset to 100 mA. Bias should be reset when installing a new replacement 845 tube.

The LARGE pair of 300B tube pins should be installed toward the front of the CAD 211 AE amplifier tube socket. Look carefully at the tube pins to be sure that you insert them correctly. It is possible to force the tube pins into the socket the wrong way if you are not careful! If you install the tube wrong you will probably damage the amplifier and the tube. This damage will not be covered by the manufacturers warranty for a new amplifier. If you have any doubts about this, have the 300B tube installed by your dealer.
