Do not place the compact disc player where it could be exposed to dripping or splashing.
Do not remove or bypass the ground pin on the end of the AC cord. This may cause radio frequency
interference (RFI) to be introduced into your playback system.
The ventilation grids on the top and bottom of the Evolution 525 must be unobstructed at all times during
operation. Do not place flammable material on top of or beneath the component.
Turn off all systems' power before connecting the Evolution 525 to any component. Make sure all cable
terminations are of the highest quality, free from frayed ends, short circuits, or cold solder joints.
Caution: Visible and invisible laser radiation. When the cover is open, avoid exposure to beam.
This unit employs a laser. To prevent possible eye injury, only a qualified service person should remove
the cover or attempt to service this device. Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
THERE ARE NO USER-SERVICEABLE PA RTS INSIDE A N Y K R E L L P R O D U C T.
1 . Open the shipping box and remove the top layer of foam. You see these items:
2 . Grasp the underside of the foam end-caps that encase the Evolution 525 and lift it straight
out of the shipping box.
3 . Place the Evolution 525 in a safe location and remove the protective plastic wrapping.
Place the Evolution 525 on a firm, level surface, away from excessive heat, humidity, and
moisture. The Evolution 525 requires at least two inches (5 cm) of clearance on each side and
at least two inches (5 cm) of clearance above and below the component to provide adequate
ventilation. Installations inside cabinetry may need extra ventilation.
Do not place the Evolution 525 near hum sensitive components such as preamplifier phono
stages or turntables. Although the Evolution 525 is well shielded, placing it near these
components could create interference and cause hum.
The Evolution 525 has superb regulation and does not require a dedicated AC circuit. Av o i d
connections through extension cords or multiple AC adapters. High
quality 15 amp grounded AC strips are acceptable. High quality AC line conditioners may be
used if they are grounded and meet or exceed the unit's power supply rating of 50 VA .

Connecting the
Evolution 525
to Your System
Follow these steps to connect the Evolution 525 to your system.
1 . Make sure all power sources and components are off before connecting inputs and
outputs.
2 . Neatly organize the wiring between the Evolution 525 and all system components.
Separate AC wires from audio cables to prevent hum or other unwanted noises from
being introduced into the system.
3 . Balanced outputs use three-pin XLR connectors. Single-ended outputs use RCA
connectors. Maintain the correct left/right orientation of these outputs (EV 525a and
EV 525av).
4 . To play DVD discs (EV 525v and EV 525av), connect desired video output to
preamp/processor or display's video input. For use with a preamplifier/processor,
connect digital audio output to digital audio input. A l t e r n a t i v e l y, connect multi-
channel analog audio outputs to preamplifier/processor multi-channel analog inputs.
5 . For two-channel compact disc playback only, connect the Evolution 525 digital audio
outputs (EV 525t) to the D/A convertor or preamplifier/processor digital input or
balanced/single-ended analog audio outputs (EV 525a and EV 525av) to the
preamplifier balanced or single-ended analog audio inputs.
6 . Plug the AC power cord into the IEC power connector on the back panel. Then plug
the AC power cord into the wall socket.
Press the back panel power switch (38) labeled “1”. When the Evolution 525 is
initialized and in the stand-by mode, the red stand-by LED (2) on the front panel
illuminates. Then press the power button on the front panel or the power key (1) on the
remote control, to place the Evolution 525 in the operational mode. When the blue
power LED (2) illuminates, the Evolution 525 is in the operational mode.
1. Insert disc into the slot (23)
2. Press the play button or key. The format type is visible in the front panel display. T h e
format type disappears and the front panel display reads TRACK 1 and the track
time, as the disc begins playing.
3 . Adjust the volume level through your system volume control.
4 . Press the stop button or key to end disc playback.
5 . Press the play button or key (6) to begin playback again, from the first track.
6 . To return the Evolution 525 to the stand-by mode, press the power button or key (1).

Krell recommends using balanced
interconnect cables. Balanced
interconnect cables not only can
minimize sonic loss but are also
immune to induced noise,
especially with installations using
long cables. Balanced connections
have 6 dB more gain than single-
ended connections. When level
matching is critical, keep this gain
value in mind.
N o t e
The Evolution 525 reads data discs.
For example, if you prepare a CDR or
DVR containing MP3 audio files, you
can play the discs on the Evolution
525. The following terminology appears
in the front panel display, to help you
navigate a data disc:
ROOT = The beginning of the disc.
F = A closed folder.
TO P = An open folder.
Press the enter button or key (11) to
open a folder, move to the previous
f o l d e r, or play a track.
Press the up and down arrows or keys
(10) to move between tracks in a folder.
