• Evolution 525v - 1080p DVD video transport, digital audio output only

• Evolution 525a - High performance CD player with Krell CAST™ and balanced analog

outputs

• Evolution 525av - Complete package including audio and video options

Please contact your authorized dealer, distributor, or Krell if you have any questions not
addressed in the owner’s reference.

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 PARTS INSIDE ANY KRELL PRODUCT.

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. Avoid
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. Alternatively, 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. The
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).

1. Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.

2. Unplug this apparatus during lightning storms or when unused for long periods of time.

3. Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as a power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.

4. The apparatus must be placed on a firm, level surface where it is not exposed to
dripping or splashing.

5. The ventilation grids on the top of the apparatus and the space underneath it must be
unobstructed at all times during operation. Do not place flammable material above or
beneath the apparatus.

6. Before making connections to the Evolution 505, ensure that the power is off and other
components are in mute or stand-by mode. Make sure all cable terminations are of the
highest quality, free from frayed ends, short circuits, or cold solder joints.

Please contact Krell if you have questions not addressed in this guide.

AC POWER GUIDELINES

P/N 310415
v 1.0

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.

Note

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.
TOP = An open folder.
Press the enter button or key (11) to open a folder,

move to the previous folder, or play a track.
Press the up and down arrows or keys (10) to move

between tracks in a folder.

Pin assignments for XLR
connectors:

Pin 1 Shield (ground)
Pin 2 Non-inverting (hot) (0°)
Pin 3 Inverting (cold) (180°)
