SAFETY INSTRUCTIONS
1.
Read Instructions – All the safety and operating
instructions should be read before the appliance is
operated.
2.
Retain Instructions – The safety and operating instructions
should be retained for future reference.
3.
12.
Power-Cord Protection – Power-supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the
appliance.
Heed Warning – All warnings on the appliance and in the
operating instructions should be adhered to.
14.
Cleaning – The appliance should be cleaned only as
recommended by the manufacturer.
4.
Following Instructions – All operating and use instructions
should be followed.
15.
Power Lines – An outdoor antenna should be located away
from power lines.
5.
Water and Moisture – The appliance should not be used
near water – for example, near a bathtub, washbbowl,

swimming pool, and the like.
16.
6.
Carts and Stands – The appliance should be used only with
a cart or stand that is recommended by the manufacturer.
6A.
An appliance and cart
combination should be
moved with care.
Quick stops, excessive
force, and uneven
surfaces may cause
the appliance and cart
combination to overturn.
Outdoor Antenna Grounding – If an outside antenna is
connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides
information with regard to proper grounding of the mast
and supporting structure, grounding of the lead-in wire to
an antenna-discharge unit, size of grounding conductors,
location of antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode.
See Figure A.
17.
Nonuse Periods – The power cord of the appliance should
be unplugged from the outlet when left unused for a long
period of time.

location or position does not interfere with its proper
ventilation. For example, the appliance should not be
situated on a bed, sofa, rug, or similar surface that may
block the ventilation openings; or, placed in a built-in
installation, such as a bookcase or cabinet that may
impede the flow of air through the ventilation openings.
19.
Damage Requiring Service – The appliance should be
serviced by qualified service personnel when:
9.
Heat – The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.
10.

(6) Cueing
•
"Cueing" is the action of moving to a specified point (the cue point) and waiting for playback to begin (cue mode). When the
PLAY/PAUSE button is pressed after cueing, playback starts immediately. (Instant Start)
• When the track search operation is completed after pressing the TRACK buttons, the player locates the position at which
the sound starts and automatically cues there. (Cue to Music)
• I f the CUE button is pressed during the search operation with the jog dial or the scanning operation with the shuttle dial,
the point at which the button is pressed is set as the cue point and cueing starts.
• Figure 12 shows the relationship between the play and back cue operations.

(7) Searching
• Searching is the function which allows you to continuously monitor a certain section of the disc and manually change the
playback position in small increments. Searching is used to set playback start points and loop points with precision.
• Turn the jog dial while in the play, pause or cue mode to begin searching. The sound for one revolution of the disc is output
repeatedly. The point at which the sound starts (the search point) is indicated on the LCD.
• When the jog dial is turned, the point from which the sound is output moves a number of frames corresponding to the number
of clicks, and the time display on the LCD also changes.
• The search point moves in the forward direction when the jog dial is turned clockwise, in the reverse direction when the jog
dial is turned counterclockwise.
• The search point displayed on the LCD during the search operation is automatically stored in the memory as the cue
point.
• I f the jog dial is turned while in play mode, playback resumes
automatically once the jog dial is released.

Scanning
Scanning allows you to move quickly forward or backward through the CD while monitoring the sound, and is used, for example, to locate a specific section in a song.
Turn the shuttle dial while the player is in the play, pause or cue modes to begin scanning. The disc moves rapidly forward
or backward and the sound is output. The current point (scan point) is indicated on the LCD.
The scanning speed depends on how far from the center point the shuttle dial is turned. The more it is turned, the faster the
scanning speed.
Turn the shuttle dial clockwise to scan in the forward direction, counterclockwise to scan in the reverse direction.
The scanning point indicated on the LCD is automatically
stored in the memory as the cue point.
• When the shuttle dial is released during scanning, it returns
to the neutral position, scanning stops and the search mode
is set. However, if scanning was started from play mode,
playback resumes.
• When the dial is turned all the way to the end, the point of
playback is skipped approximately one minute, played for
about 3 seconds, then skipped again, etc.

MATCHING THE BEATS PER MINUTE (BPM)
• With the DN-2500F, there are two ways to adjust the playing speed and match the BPMs of the two CDs:
• Use the pitch slider to adjust the BPM statically. One of three adjustments ranges can be selected by the Preset Mode.
• Use the PITCH BEND buttons to change the BPM temporarily. Use this after adjusting the BPM with the pitch slider.
(1)
Pitch Slider
• To adjust the BPM by sliding the pitch slider up or down, first press the PITCH button to enable the pitch slider. The PITCH
LED will turn on.
• With the pitch slider, the pitch can be adjusted within one of three ranges (± 4%, ± 8% or ± 16%).
( Can be selected with preset item 3.)
• The BPM decreases when the pitch slider is moved upwards, increases when the pitch slider is moved downwards.
Figure 15
16
(2) Pitch Bending
The BPM increases or decreases temporarily while the PITCH BEND + or PITCH BEND - button is pressed.
The extent to which the PITCH BEND button changes the BPM is proportionate to the amount of time the button is pressed.
The longer the button is held down, the greater the percentage of change.
The PITCH BEND button changes the BPM within a range of ± 12% when the pitch adjustment range is ± 4% or ± 8% ,
and within a range of ± 1 8% when the pitch adjustment range is ± 16%.
Figure 16 shows an example of how to use the pitch bend function. In this example, both players are playing and the BPM
has already been matched with the pitch sliders.
The CD1 and CD2 BPMs are matched
but the bass beats are off.
The bass beats also match.

Precautions on handling compact discs
Do not allow fingerprints, oil or dust to get on the surface of the disc.
I f the disc is dirty, wipe it off with a soft dry cloth.
We recommend using DENON's AMC-22 CD CLEANER.
Do not use benzene, thinner, water, record spray, electrostatic-proof chemicals, or silicone-treated cloths to
clean discs.
Always handle discs carefully to prevent damaging the
surface; in particular when removing a disc from its
case or returning it.
Do not bend the disc.
Do not apply heat.
Do not enlarge the hole in the center of the disc.
Do not write on the label (printed side) with a hardtipped implement such as a pencil or ball point pen.
Condensation will form if a disc is brought into a warm
area from a colder one, such as outdoors in winter. Do
not attempt to dry the disc with a hair dryer, etc.
2.
Precaution on storage
After playing a disc, always unload it from the player.
Always store the disc in the jewel case to protect from
dirt or damage.
Do not place discs in the following areas:
1) Areas exposed to direct sunlight for a considerable
ti me.
2) Areas subject to accumulation of dust or high
humidity.
3) Areas affected by heat from indoor heaters, etc.
