Save the RCD-991 shipping carton and all enclosed packing mate-  
rial for future use. Shipping or moving the RCD-991 in anything  
other than the original packing material may result in severe dam-  
age that is not covered by the warranty.

COMPACT DISC PLAYER RCD-991  
Fill out and send in the owner’s registration card packed with the  
RCD-991. Also be sure to keep the original sales receipt. It is your  
best record of the date of purchase, which you will need in the  
event warranty service is required.  
Output Connections  
The RCD-991 gives you a choice of analog or digital output sig-  
nals. The analog output signal from the built-in Digital to Analog  
converter is used with conventional analog audio components.  
The digital output, which provides an unprocessed digital data  
signal, is used with outboard D/A converters or digital processors.  
Placement  
Use common sense when placing the RCD-991 in a cabinet or  
when stacking other equipment. Make sure that the shelf or cabi-  
net can support its weight. Do not stack heavy components on top  
of the RCD-991. Avoid placing the unit where it may be subject to  
excessive heat such as on top of a large power amplifier or near a  
heat register. For best performance, avoid placing the unit where  
it may be subject to vibration, such as near a speaker.  
Note: To prevent loud noises that neither you nor your speakers  
will appreciate, make sure the CD player is turned off when you  
make any signal connections.  
13  
Analog Outputs  
[See Figure 2 for wiring illustration]  
AC Power and Control  
The analog output signal is available from two different types of  
connectors on the back panel of the RCD-991. A pair of standard  
RCA jacks supplies a conventional unbalanced analog output sig-  
nal from the RCD-991 to the source inputs of an audio preamplifier,  
integrated amplifier, or receiver. Alternatively, a pair of three-pin  
XLR-style jacks supplies a balanced-line analog output signal for  
use with preamplifiers that are equipped with similar input con-  
nections.  
16  
AC Power Input  
Your RCD-991 is configured at the factory for the proper AC volt-  
age in the country where you purchased it (either 115 volts or 230/  
240 volts. The AC line configuration is noted on a decal on the  
back panel.  
RCA connections are found on virtually all components. Not as  
many components feature XLR connections, but, when available,  
they may provide less chance of noise and improved signal qual-  
ity. Use whichever type of signal connection matches your par-  
ticular system configuration.  
Note: Should you move your CD player to another country, it may  
be possible to reconfigure it for use on a different line voltage. Do  
not attempt to perform this conversion yourself. Opening the en-  
closure of the RCD-991 exposes you to dangerous voltages. Con-  
sult a qualified service person or the Rotel factory service  
department for information.  
Select high quality audio interconnect cables. Connect the left  
channel output of the RCD-991 to the left channel source input on  
the preamplifier or other component. Connect the right output of  
the RCD-991 to the right channel source input on the preamplifier  
or other component.  
The RCD-991 should be plugged directly into a 2-pin polarized wall  
outlet or into the switched outlet on another component in your  
audio system. Do not use an extension cord.  
Be sure the power switch on the front panel of the RCD-991 is  
turned off (in the "out" position). Then, connect the supplied power  
cord to the AC power receptacle on the rear of the unit and the  
AC power outlet.  
14  
15  
Digital Outputs  
and Switch  
[See Figure 3 for wiring illustration]  
If you are using the RCD-991 as a disc transport with an outboard  
D/A converter or other digital processor, you need an unproc-  
essed digital data stream from the RCD-991, taken before the  
built-in D/A converter. This signal is supplied by the RCD-991s  
back-panel digital output jacks.  
If you are going to be away from home for an extended period of  
time such as a month-long vacation, it is a sensible precaution to  
unplug your CD player (as well as other audio and video compo-  
nents) while you are away.  
Both optical and coaxial digital signal connectors are provided.  
Use whichever type best matches your other components. Using a  
standard 75 ohm coax or optical digital cable, connect the appro-  
priate RCD-991 digital output jack to the digital input connector on  
the outboard D/A converter.

Power Switch  
and Power Indicator  
The power switch is located on the front panel of your CD player.  
To turn the CD player on, push the switch in. The LED indicator  
above the switch and the DISPLAY will light up, indicating that the  
CD player is turned on. To turn the CD player off, push the button  
again and return it to the "out" position.  
A switch to the right of the digital outputs enables or disables the  
digital outputs. To use the digital outputs, this switch must be in  
the on position. If you are not using the digital outputs, we recom-  
mend turning the switch off, because it removes the digital output  
circuitry from the signal path.  
Note: If you are using a switched outlet to turn on and off your  
CD player, you should leave the power switch in the "on" position.  
When AC power is applied to the unit, it will power up in fully ac-  
tive mode.

OPEN Button  
Operation  
When the transport disc drawer is closed, pressing this but-  
ton automatically opens the drawer. To close the drawer,  
press this button again. The drawer can also be closed by  
pressing the PLAY button.  
The RCD-991 can be operated using its front panel buttons or  
from corresponding buttons on the supplied infrared remote con-  
trol. Specific instructions for each of these controls are detailed  
below. Some of the buttons are duplicated on the front panel and  
on the IR remote control. However, there are many instances  
where the buttons are only available on one or the other. These  
are noted in the following instructions.  
When the drawer is open, the DISPLAY will read “OPEN”.  
When it is closed with no disc, the display will read “NO  
DISC”. When the drawer closes with a disc inserted, the DIS-  
PLAY will indicate the number of tracks on the disc and the  
total time of the disc in minutes and seconds.  
Infrared Remote Control

PLAY Button  
Before using the IR remote control, it is necessary to install two  
“AAA” batteries (supplied). Remove the plastic cover on the  
back of the IR remote, install the batteries (observing the + and –  
polarity indications), and reinstall the cover.  
Press the PLAY button to start playing the disc. If the disc  
drawer is open, it will close automatically. The number of the  
track being played and the time remaining will be shown in  
the display, along with the PLAY indicator.  
To use the IR remote control, aim it at the IR sensor located on  
the front panel of the RCD-991.  
Normally, the disc will start playing with the first track. How-  
ever, you can select a different track using the TRACK but-  
tons or the DIRECT ACCESS buttons (see below) before  
pressing the PLAY button to start playing a different track.

Display  
A lighted DISPLAY on the front panel of the RCD-991 provides  
useful information about the status of the unit, activation of spe-  
cial features, and track/time information for the disc being  
played. Each of these indicators is described in the detailed op-  
erating instructions that follow.

Disc drawer  
A motor-driven disc drawer, located in the center of the RCD-991,  
slides out to accept a compact disc and retracts to play the disc.  
Place the compact disc in the drawer label-side up. Make sure  
the disc is properly centered in the tray.  
12 29  
TRACK Buttons  
These buttons are used to select tracks on the disc. When a  
disc is playing, pressing the right TRACK button advances to  
the beginning of the next track. Pressing the left TRACK but-  
ton returns to the beginning of the current track. Pressing  
twice quickly in succession returns to the beginning of the  
previous track. The new track number appears in the DIS-  
PLAY.  
The drawer can be closed in two ways: pushing the  
OPEN button or pushing the PLAY button.  
Transport Control Buttons  
These buttons are also used to select a track before pressing  
the PLAY button or when memorizing tracks for the PRO-  
GRAM play mode (see below). These selections are made by  
continuously pressing the TRACK buttons until the desired  
track is reached.  
These buttons provide basic control functions for the disc trans-  
port mechanism. Except where noted, all functions are available  
on the RCD-991 front panel and the IR remote control. The circled  
numbers provide a convenient reference for finding the button  
on the illustrations of the RCD-991 and the IR remote control at  
the front of this manual.  
In PROGRAM mode, the TRACK buttons advance or reverse  
to the next track in the memorized selection list.

COMPACT DISC PLAYER RCD-991  
In addition to properly reproducing the enhanced sound quality of  
HDCD-encoded discs, an HDCD-capable player performs signifi-  
cantly better with conventional CDs thanks to an advanced digital  
filter that not only provides precise upsampling but optimizes the  
performance of the D/A converter by minimizing quantizing errors  
with dither, deglitching circuits, and slew rate adjustments.  
18  
DIRECT ACCESS Buttons (remote only)  
These eleven numeric buttons (labeled 1 through 10 and >10) are  
used to directly access a track from the remote control instead of  
stepping through the tracks using the TRACK buttons.  
The first ten tracks on a disc can be selected by pressing the cor-  
responding button. For example, to play the third track, press the 3  
button on the remote control. The number of the selected track  
will appear in the center of the DISPLAY and the track will play.  
HDCDs operation is completely transparent. The system automati-  
cally senses an HDCD-encoded disc and decodes it according to  
the instructions recorded on the disc. The HDCD LED on the front  
panel lights to when an HDCD-encoded disc is being played.  
To select track 11 or higher, first press the >10 button, then all of  
the digits of the desired track number. For example, to play track  
12, press >10, then 1, and then 2. Use the 10 button for the 0 digit.  
To play track 20, press >10, then 2, and then 10.  
When playing conventional CDs, you hear the music exactly as  
the artist intended but with a startling realism, thanks to the au-  
dible benefits of the advanced HDCD filter.  
There is also a four by four matrix of track numbers (1 – 16) lo-  
cated at the right side of the display. This display indicates all of  
the tracks on the disc. If there are more than 16 tracks on the disc,  
all of the digits will light accompanied by the word OVER, regard-  
less of which track is playing. This matrix is independent of the  
main numeric area of the DISPLAY, which will always indicate the  
currently playing track, even if above 16.  
25  
PROGRAM Button (remote only)  
This button, labeled PROG, allows you to memorize as many as 20  
tracks on the current disc for playback in a specific order. For ex-  
ample, you could instruct the RCD-991 to play track 5, followed by  
track 3, followed by track 8. Programs can only be memorized  
from the handheld remote control. To begin a program:  
The DIRECT ACCESS buttons may also be used to memorize tracks  
in PROGRAM mode (see below).  
1) Insert a disc and press the OPEN button to close the drawer. The  
RCD-991 will read the contents of the disc.  
2) Press the PROGRAM button on the remote control. The PROGRAM  
indicator will light up in the DISPLAY, along with “P–00” indicating  
that the unit is waiting for the first track to be memorized.  
28  
SEARCH Buttons (remote only)  
These buttons fast forward or fast reverse through the currently  
playing disc as long as they are pressed. While the buttons are  
pressed, you will hear high-speed audio. Releasing the buttons re-  
turns to PLAY mode.  
3) Enter the first track number using the DIRECT ACCESS buttons on  
the remote control. Your selection will be memorized automati-  
cally and the DISPLAY indicator will change to “P–01”, indicating  
that one track has been memorized. Continuing entering the rest  
of your selections using the DIRECT ACCESS buttons. There is no  
need to press the PROGRAM button between selections; each se-  
lection is memorized as soon as it is entered.  
Additional Features  
These convenience features add extra functionality to the  
RCD-991, including the ability to play high-definition HDCD discs,  
to memorize a group of tracks to be played, to repeat a disc, pro-  
gram, or track over and over, to play the tracks on a disc in ran-  
dom order, to automatically play the first 10 seconds of each  
track, to select from several available time displays, and to select  
different dither modes.  
Once you have memorized a play list, the RCD-991 remains in  
PROGRAM mode until you open the disc drawer or press the  
STOP button twice in succession. If you press the PLAY button,  
the memorized program will play instead of the entire disc, start-  
ing with the first selection in the memorized list.  
When a PROGRAM has been memorized, most functions that  
would normally effect the entire disc operate on just the memo-  
rized program. For example, the TRACK buttons advance to the  
next track in the memorized program, not the next track on the  
disc. Likewise, the REPEAT button (see below) continuously plays  
the memorized program, not the entire disc.  
2
HDCD  
HDCD® (High Definition Compatible Digital) is a system developed  
by Pacific Microsonics, Inc. that enhances a CDs sound quality. It  
is based on the latest research in how we hear and depends on  
sophisticated algorithms (or mathematical equations) to optimize  
the link between the recording studio and our home.  
27  
REVIEW Button (remote only)  
This button is used to review the memorized tracks in PROGRAM  
mode. Press the button and the first memorized track number will  
appear in order in the DISPLAY, flashing for approximately five  
seconds. Pressing the REVIEW button again while the track num-  
ber is flashing will continue the review sequence, showing the  
next memorized track. Continue pressing the REVIEW button to  
see the complete memorized track list.  
In the recording process, an HDCD encoder analyzes music to de-  
termine how best to reproduce it. The encoder then embeds a se-  
ries of instructions on a CD along with the music. These  
commands tell an HDCD-equipped CD player how to best repro-  
duce the complex musical signal so that we hear even more of the  
original recording than conventional CDs allow us to.  
4
RCD-991  
If you do not press the REVIEW button while the track number is  
flashing, the review process is terminated and the unit resumes  
whatever mode it was in before you started to review, except that  
the last reviewed track number will remain active and shown in  
the display.  
time remaining on the entire disc (or memorized program).  
Pressing the button a third time reverts to the standard  
elapsed time display. When the TIME feature is activated, the  
word REMAIN appears in the DISPLAY.  
DITHER Button (front panel only)

Note that you may remove a selection from the play list during the  
review procedure using the CLEAR button, as described below.  
DITHER Display  
3
Dither is a very small amount of digital noise added to a sig-  
nal to improve a CD player’s overall sound quality. Proper  
types and amounts of dither can improve a digital-to-analog  
converter’s linearity, particularly during very soft (low-level)  
musical passages.  
26  
CLEAR Button (remote only)  
This button allows you to remove a track selection from the  
memorized program play list during the review procedure de-  
scribed above. Follow the review procedure until the desired  
track number is flashing. Then, instead of pressing the REVIEW  
button to continue, remove the displayed track by pressing the  
CLEAR button while the number is still flashing. You may then con-  
tinue the review procedure.  
Dither’s precise effects vary depending on: the exact dither  
type and level chosen, D/A converter type, other system  
characteristics, and the type of music being played.  
The RCD-991 allows you to choose different types and levels  
of dither. The effects may vary but careful listening will re-  
veal what selection is best for your system and musical taste.  
21  
RANDOM Button (remote only)  
This instructs the CD player to play tracks from the entire disc in  
random order. Once all of the selections have been played once,  
the disc will stop playing, unless the REPEAT Button (see below)  
has been engaged, in which case the random play will continue  
until the STOP button is pressed. When the RANDOM button is en-  
gaged, the word RANDOM appears in the DISPLAY.  
Select different dither types by sequentially pushing the  
DITHER button. The DITHER DISPLAY will change to indicate  
the kind of dither then being generated. Remember that  
dither-induced sonic differences are subtle and that there is  
no wrong setting for your RCD-991. Experiment to find the  
most pleasing dither selection.  
19  
REPEAT Button (remote only)  
This button allows you to repeat the current track or the entire  
disc continuously until the feature is cancelled by disengaging the  
REPEAT button or pressing STOP. The REPEAT button steps se-  
quentially through the available options. Press the button once  
and the RCD-991 will repeat just the current track, displaying the  
indicators REPEAT 1 in the DISPLAY. Press the button a second  
time and the RCD-991 will repeat the entire disc, displaying RE-  
PEAT ALL in the DISPLAY. Press the button a third time to cancel  
the REPEAT function.  
The DITHER DISPLAY, located to left of the main DISPLAY,  
shows a single digit indicating the types of dither provided by  
the RCD-991 as follows:  
A blank dither setting indicates that dither is off.  
Dither settings from 0 through 6 are seven progressively  
higher levels of ultrasonic noise-shaped dither. The 0 setting  
provides minimum amplitude dither which corrects quantiza-  
tion errors only. The 1-6 settings add increasing levels of ul-  
trasonic (30-80 kHz) weighted dither designed to smooth out  
non-linearity errors in multi-bit D/A converters. The 1 setting  
indicates the least amount of noise shaped dither; the 6 set-  
ting indicates the highest level.  
As noted above, REPEAT can be used in conjunction with the  
RANDOM play feature.  
Note: The REPEAT function is automatically cancelled when the  
disc drawer is opened.  
A dither setting of 7 is minimum amplitude triangular PDF  
dither. This low level broadband dither is not weighted to-  
wards the ultrasonic range and is intended to correct quanti-  
zation errors only. It has a similar effect as the 0 setting, but  
with a different type of noise.  
20  
SCAN Button (Remote Only)  
This feature automatically plays the first ten seconds of each  
track on the disc. To activate the feature, press the SCAN button.  
The word INTRO appears in the DISPLAY. To stop scanning and re-  
sume normal operation at the current track, press the SCAN but-  
ton again or press the PLAY button.  
A blank dither setting indicates that dither is off.  
24  
TIME Button (Remote Only)  
Normally, the RCD-991 displays the elapsed time of the currently
