NOTE ON INSTALLATION

IMPORTANT! 

Before installation, remove the red plastic transit

screw from the bottom of the unit. Remove by turning 90° counter-

clockwise and then pulling it out of its position. Never use force to

remove the screw; refer also to the label attached to the transit

screw. Retain the transit screw, should you need to transport the CD

Player over some distance (e.g. when moving house). To avoid

damage, it is important that the transit screw is replaced.

Install the NAD C521 Compact Disc player on a level, vibration-

free surface. (Severe vibration, or operation in a tilted position,

may cause the player to mis-track.) The player may be stacked

with other stereo components, as long as there is adequate

ventilation around it. If the player is placed in close proximity to

a radio tuner (AM or FM), a VCR, or a television set, the operation

of its digital circuits may produce static that would interfere with

reception of weak broadcast signals. If this occurs, move the CD

player away from other devices or switch it off when viewing or

listening to broadcasts.

REAR PANEL CONNECTIONS

1. LINE OUTPUT

Connect a cable from these jacks to your amplifier. Plug one end

of a twin RCA-to-RCA lead into the L (upper) and R (lower) output

jacks. Connect the other end of the cable to your stereo amplifier’s

CD input, or to any other “line-level” input jacks (such as the

AUXiliary inputs). Do NOT connect this cable to the amplifier’s

PHONO input jacks. The RCA sockets on your NAD C521 are

colour coded for convenience. Red and white are Right and Left

audio respectively, and yellow for NAD Link and Digital Out.

Ensure that leads and sockets are not damaged in any way and all

sockets are firmly pushed home.

2. DIGITAL OUTPUT

The digital playback signal is available at this output jack. The

serial data output is taken after the error correction but before the

digital-to-analogue conversion and filtering. The output is

transformer-isolated from the built-in D-to-A circuits. It may be

connected to any digital signal processor that conforms to the

Sony/Philips (SPDIF) standard. 

To use the digital output, connect a cable from this jack to the “CD

Digital” or equivalent input on a digital processor or recorder. For

best results, the cable should be a 75 ohm coaxial cable of the

type used for video signals, with an RCA phono plug at each end.

(To distinguish them from similar phono-plug cables used for

analogue audio signals, video and digital signal cables often are

colour-coded with yellow plugs.)

3. NAD LINK IN/OUT

The NAD-Link connector is used to pass commands from other units

fitted with NAD-Link connectors. This allows centralised control of a

complete system, and also allows some of the basic functions of

other NAD components (such as a tuner, or cassette-deck) also

equipped with NAD-Link to be controlled with an NAD system remote

control. To function with such other units, connect the C521’s NAD-

Link Out to the NAD-Link In on the other unit. NAD-Link connectors

can be daisy-chained, IN to OUT, so that a whole system can be

controlled from the remote control facilities of one unit.

NOTES: 

It is advisable not to connect NAD-Link if these units that

have their own built-in remote control command receiver and are

positioned together, in direct view from the remote control

handset. If you are unsure, try operating the products without

NAD-Link first; If the unit responds to the remote control

command, it will not be necessary to connect NAD-Link.

Never loop the last unit back to the first NAD unit in the NAD-Link

chain. Unplug all units from the mains before connecting or

disconnecting NAD-Link.

4. AC LINE CORD

Connect this power cord to an AC mains wall outlet or to an AC

convenience outlet at the rear of your amplifier. 

FRONT PANEL CONTROLS

1. POWER ON/OFF

Press this green button to switch on the power to the disc player.

Press again and release to switch the power off. The display will

light up to indicate the unit is switched on and ready for use.

2. DISC DRAWER

To play a disc, press the OPEN button to open the disc drawer.

Place the CD within the large circular recess in the drawer, with

its transparent playing surface facing down. The label must face

UP. CD-3 discs (3-inch CD “singles”) can be played without the

aid of an adapter. Place the disc in the drawer, centered in the

smaller circular recess, with its label facing UP.

NOTE: 

This player was not designed to accommodate a “damping

disc” placed on a CD, nor two CDs stacked together. It plays audio

CDs, but not discs identified as CD-RW, CD-V, DVD, CD-I, CD-ROM,

or PHOTO CD. Refer also to chapter “A note on CD-R and CD-RW

audio discs”
