Playback Speed Control
- The long stroke sliding fader adjusts the play speed of CDs or MP3 discs
by ±12.0 percent in increments of 0.1 percent. This pitch control can
be turned off for normal playback by pressing the pitch button.
- Pitch lock function: When pressing the pitch button again while pitch
control mode is on and the pitch display is lit, you cannot change
playback speed even if you move the sliding fader.
- Apart from pitch control on the front panel, playback speed can also be
adjusted using a preset function that allows the speed to be increased
by up to ±3.0 percent in increments of 0.2 percent. When this preset
function is engaged, pitch control on the front panel is disabled.
Program Play (Maximum 99 Tracks)
- Three different programs can be stored in nonvolatile memory.
- The unit incorporates a memory function that boots the unit
up automatically in the program mode when a programmed
disc is inserted.
End Monitor
When this button is pressed while in standby mode, the end of the
selected track is reviewed. The review duration can be preset between
5 and 35 seconds. While in continuous mode, the unit plays the final
portion of the last track on the disc.
End of Message (EOM)
At the end of a track, the FL display flashes, providing a visual warning
to the operator that the track will end shortly. The point at which the
EOM warning begins can be preset within a range of 0 to 60 seconds,
seven steps.
Power-On Playback
When the unit is powered up:
1) Play the entire disc from the first track of the disc
2) Play the program sequence from the beginning
Next-Track Reserve
Turning the track select knob during playback reserves the next track to
be played back. After the current track has finished playing back, the
unit continues by playing back the reserved track.
Search Accuracy (One Frame = 1/75 Second—CD Only)
RS-232 Serial Port (AMX/CRESTRON compatible)
Parallel (D-Sub 25-Pin)
When connected to an external controller, the DN-C635 allows users to
use play, pause, and conduct other simple functions easily by contact
closure control.
Fader Start
The parallel remote (D-sub 25-pin) connector allows fader start operation
from a mixing console. You can select fader start mode as follows:
Start Only - Player starts when fader switch is turned on.
Start, Pause - Player starts when fader switch is turned on; player pauses
when fader switch is turned off.
Sleep Function
This function increases drive life by shutting down the servo systems of
the transport if a button is not pressed within the time specified. The
sleep time can be specified in the preset menu or defeated.
Function Preset
Three different function presets can be stored into a non-volatile memory
via buttons operated on the front panel (“*” indicates the default setting).

DN-C635 Expanded Connection In/Out
1. Cascade Function
The ports (CASCADE IN/OUT) of multiple DN-C635 units can be linked
by cables to enable continuous relay playback among the units.
2. Synchronized Recording
The port (EXT. SYNC OUT) of the DN-C635 unit can be linked to
other Denon recorders (DN-780R and other models) by cables to
enable simultaneous recording. (Up to 20 units can be connected
for continuous recording of the source.)
Eight Times Oversampling Digital Filter
Display of Playback Locations
A bar graph display indicates playback points on the track being
played. Elapsed time and remaining time displays are switched using
the TIME button.
Mono Playback
When “MONO” is on in the preset menu, tracks recorded in stereo are
output as a mix of L and R channels.
Next Track Standby
Pressing the STDBY/CUE button during play stops playback and makes
the unit enter a standby at the beginning of the next track. This comes
in handy in combination with the program function when determining
tracks (numbers) to be played back.
Other Features

- Headphone jack with volume control
