Warnings

To prevent re, or shock hazard, do not

expose your CD9SE to rain or moisture.

Do not place objects containing

water on top of this unit.

This unit contains voltages which can cause

serious injury or death. Do not operate with cover removed. Refer servicing to your

authorized Audio Research dealer or other qualied personnel.

The detachable power cord on your CD9SE is

equipped with a heavy gauge, 3-conductor cable and a standard three-prong grounding plug. For absolute protection, do not defeat the ground power plug. This

provides power line grounding of the CD9SE

chassis to provide absolute protection from electrical shock.

For continued protection against re hazard,

replace the fuse only with the same type

and rating as specied at the fuse holder.

Do not operate the CD9SE player without the

supplied CD9SE clamp installed on the CD.

Gently place clamp on disc to prevent damaging the spindle mechanism.

If the unit is to be operated in an enclosure

such as an equipment rack, make certain

that adequate airow above and to each

side of the unit is provided, and ensure that the ventilation fans on the back panel are not obstructed.

The appliance coupler at the rear of this unit

must be accessible for emergency power disconnect.

This unit is RoHS compliant.

A note about packaging...

Save all packaging in a dry place away

from fire hazard. Your CD9SE compact disc

player is a precision electronic instrument and should be properly cartoned any time shipment is made. You may not have occasion to return your unit to the factory for service, but if that should prove necessary, or other occasion requiring shipment occurs, the original packaging

will protect your CD9SE from unnecessary

damage or delay.

Whenever the CD9SE power is on, the door

covering the drive mechanism/tray area should remain fully closed after inserting or removing a CD. Following this procedure will maintain proper ventilation and also

minimize dust intrusion on the lens and

drive mechanism.

Before operating the CD9SE

Carefully remove each of the six vacuum

tubes (ve 6H30, one 6550WE) from

their protective foam blocks and install them in their sockets on the circuit board, matching the “V” number on the tube with each matching numbered tube socket.

The 6550WE is mounted horizontally in

the socket on the metal bracket. When installing or removing the 6550WE vacuum tube in the V5 socket location, grasp the metal bracket with one hand while inserting the tube with the other to prevent

exing of the circuit board and possible

damage to it.

Note: double damping rings are installed

at the factory on each 6H30 tube for maximum sonic performance.

Installation

In your system

To insure normal component life and safe

operation this unit must be operated only in an upright position. Adequate

airow and proper cooling can occur

only if there is no restriction above and behind the unit and on either side.

The special non-marring elastomer feet

provide adequate spacing and stability only on a smooth, hard surface, and also assist to isolate the CD player from spurious vibrations. For upright stability and best performance, never operate the unit while it is sitting on a soft surface such as a thick rug or carpet.

Due to its weight, this CD player must

be supported on a surface specically

rated for such a load. Check with the manufacturer of your support system to be sure it is rated to handle this weight.

If the unit is to be operated in an enclosure

such as an equipment rack, make certain

that adequate airow above and to

each side of the unit is provided.

The ‘ambient’ operating temperature should

never exceed 120° F or 49° C. Improper installation will cause premature tube

failure and will aect your warranty,

as well as the service life of the unit.

It is normal for a vacuum tube CD player

to run quite warm, and if used for prolonged periods, hot to the touch. All components within are, however, operated at safe, conservative levels

and will not be improperly aected

thereby, providing the requirements outlined above are adhered to.

A Note about Vacuum Tubes

The vacuum tubes in your CD9SE have

been burned in, tested and electrically matched to provide the best performance

and reliability of your preamplier. That

said, vacuum tubes must be replaced from time to time. The 6H30 tubes in

the CD9SE should have an expected

life of approximately 4,000 hours, while the 6550WE tube in the power supply should have a life expectancy of approximately 2,000 hours. These life expectancies are only approximate.

Connections

Digital Connections

The CD9SE offers four digital inputs, and two

standard digital output options. Which option is best for your system will depend on your personal listening preference, the nature of your system installation requirements, and the options allowed by your external digital processor, if one is used.

Digital Inputs

RCA: Connect to a transport or other device

equipped with an RCA digital output. Press the INPUT button until the ‘RCA’ LED is illuminated.

USB: Connect to a Windows-based PC or

Mac computer for music playback from your computer. Press the INPUT button

until the ‘USB’ LED is illumindated.

Software installation is not necessary for Mac or Linux users. Windows users can find the necessary software at www.audioresearch.com.

AES/EBU: Connect to a transport or other

device equipped with an AES/EBU digital output. Press the INPUT button until the ‘AES/EBU’ LED is illuminated.

Digital Outputs

BNC: Use 75-ohm impedance coaxial cable

with locking BNC-type connectors. An RCA/BNC adaptor is also supplied.

AES/EBU: For connection to digital

processors having the AES/EBU-Standard interface.

Analog Outputs

Single-Ended (RCA): For connection to

the inputs of a line-level preamplier or integrated amplier.

Balanced (XLR): For connection to the

balanced inputs of a line-level preamplier.

Caution

The digital outputs supply only a digital

signal and should therefore only be connected to an input which is suitable for this signal. Never connect either of these digital outputs to a non-digital input of

a preamplier (such as those labeled CD, AUX, PHONO, TAPE, etc.) or to a power amplier. To do so is to risk damage to your

system and may void any or all warranties involved.

Toslink: Connect to a transport, computer

or other device equipped with Toslink

(optical) digital output. Press the

INPUT button until the ‘Toslink’ LED is illuminated.

Systems operation note: The CD9SE

should be the rst component turned on

in your system, followed by other source components, the preamp, and last the power amp. This will prevent any extraneous turnon noise an upstream component might generate from reaching the power amp, which could amplify the noise, which might potentially damage the loudspeakers. When powering down the system, reverse the

order: Mute the preamp, turn o the power amp rst, then the preamp, then the CD9SE

and other source components. If the above is followed, it will help to avoid accidental loudspeaker damage.

Next: Selects the next track to play.

Continue pressing to cycle forward through tracks. (Track number will appear on
