A Letter from Dan D’Agostino  
Dear Audio Enthusiast,  
Thank you for your purchase of the Krell Evolution 505 SACD/CD Player. Source  
components are the first, vital link in the audio signal chain, and an audio system  
can perform no better than the source allows. For this reason, I have made every  
effort to include the best technology in the design of this new Krell product.  
At the heart of the Evolution 505 are separate, linear power supplies that insure  
perfect operating conditions for the drive mechanism and audio circuits. Discrete,  
Class A gain stages are balanced and are utilized from input to output. Current  
Mode topologies enable wide bandwidth performance, while Current Audio Signal  
Transmission (CAST) transmitters insure the most robust connection to other  
Evolution components. All of these technologies are heard in the authentic and  
satisfying audio reproduction of the Evolution 505.  
I hope that you enjoy your new Evolution 505 source component.  
Sincerely,  
Daniel D’Agostino  
Chief Executive Officer

SECTION  
ONE  
Evolution 505 Features and Technology  
This section describes the innovative features and technology of the Evolution 505  
SACD/CD Player, and defines CAST and other key terms used in this reference.  
The Evolution 505 works to carefully transmit audio signals without damaging the  
ephemeral staging and dimensional components of the music. A combination of  
advanced technologies and inspired design elevate the Evolution 505 SACD/CD  
Player’s performance to the reference level.  
Features  
The Evolution 505 has Class A, balanced, Krell Current Mode topology from input  
to output for increased bandwidth. New current mirror stages feature LED voltage  
reference. Developed for the Evolution Two, these current mirrors operate with  
three times less distortion than previous designs. A zero feedback design pre-  
serves the original harmonic structure of the recording, and a 500 K bandwidth  
promotes low distortion and phase coherent performance.  
The Evolution 505 uses PCM 1738 differential advanced segment DACs for supe-  
rior dynamic range, and a DCI drive with independent suspension for enhanced  
ergonomics and reliability.  
The Evolution 505 will read redbook, CDR, 44.1 WAV, AAC (adts, and adif), DVD-  
R, RW, +R, and RW discs. The 16 character, dot-matrix LED display is highly visi-  
ble and features an adjustable intensity.  
For flexibility of control, the back panel features a 2-way, RS-232 interface, an  
RC-5 connector, and 12 VDC trigger inputs and outputs. Krell Can Link connec-  
tors allow the Evolution 505 to operate in link mode with other Evolution compo-  
nents.  
The outputs include balanced XLR, single-ended multi-channel outputs, and a pair  
of Evolution CAST™ outputs, for the most robust connection to other Evolution  
components.  
A 65 VA linear power supply is used for the drive mechanism, for absolute voltage  
stability. A separate 45 VA linear power supply for the audio circuits is optimized to  
power critical Class A audio topologies.

Revolutionary Krell CAST Technology  
Current Audio Signal Transmission, termed CAST, is a revolutionary method of  
connecting analog audio components for unparalleled sonic performance.  
Innovative engineering combines the new Krell CAST circuitry with existing Krell  
Current Mode technology to create entire CAST systems that reproduce music  
with incredible range, tonality, and precision.  
The Voltage Signal Transmission  
and the Traditional Audio System  
Traditionally, signal is transmitted in the voltage domain between two components.  
In an audio system, each component is a discrete entity with unique characteris-  
tics that act upon the musical signal independently. Each component is unaware  
of the other components in the system. The cables that connect the components  
also have their own electrical characteristics, which affect the sonic presentation  
of the entire system. CAST transmission unifies individual components and inter-  
connects into an electrically-linked whole. The original signal remains unaltered  
from source to speaker.  
CAST Basics  
Here is how a CAST audio system works: Internally, each CAST source transfers,  
or amplifies, current using Krell Current Mode circuitry. This current signal is then  
output using CAST circuitry. When the signal is received by a CAST input, Krell  
Current Mode circuitry again takes over until the signal reaches the loudspeaker.  
By maintaining the musical signal in the current domain from beginning to end, an  
entire CAST system behaves as if it is one component. With CAST, circuit board  
properties and signal transmission aberrations between components are eliminat-  
ed. Cable impedances and their effects on the transmitted signal are non-existent.  
How CAST and Krell Current Mode Interact  
While CAST is a new method of transferring the musical signal between compo-  
nents, its origin stems from Krell Current Mode, the technology developed to  
transfer the musical signal within a component. CAST combined with Krell Current  
Mode takes circuitry signal transmission to the next evolutionary level.  
continued  
7
(SECTION ONE: Evolution 505 Features and Technology continued)  
In essence, Krell Current Mode maintains the integrity of the signal within the  
component and CAST preserves the transmitted signal between components.  
Together, CAST and Krell Current Mode technologies unify separate Krell compo-  
nents into a single global circuit. Krell Current Mode technology enjoys bandwidth  
increases up to an order of magnitude greater than their voltage based counter-  
parts. This dramatic increase in circuit bandwidth delivers near perfection in the  
audible band that typically suffers from phase distortions in voltage circuits.  
CAST Cable Construction  
A CAST system uses cables manufactured by Krell and other manufacturers spe-  
cially licensed by Krell. Thin and flexible CAST cables are constructed with the  
same build quality as other Krell components and are aesthetically matched to the  
components that Krell manufactures. An all-metal body and locking connectors  
with gold contacts are part of the standard no-compromise specification devel-  
oped for every CAST cable made.  
Evolution CAST  
By employing radical current mirror circuitry, the Evolution 505 components ele-  
vate the CAST technology to another level. This advanced use of the technology  
increases the linearity, transient speed, and bandwidth of the Evolution compo-  
nents while reducing the distortion by an order of magnitude.  
The Best Musical Performance  
When you operate a CAST system, you will hear significant improvements in every  
performance area: speed, precision, dynamic range, depth and width of the sound  
stage, transient impact, tonal balance, harmonic distortion, and more. The goal for  
CAST is the same company goal used for all Krell products. Krell strives for the  
delivery of the best performance of a musical event for you, using the full expres-  
sion of technology to date.

Definition of Terms  
The following are definitions of key terms used in this owner’s reference:  
Inputs and Outputs  
Balanced  
A symmetrical input or output circuit that has equal impedance from both input  
terminals to a common ground reference point. The industry standard for profes-  
sional and sound recording installations, balanced connections have 6 dB more  
gain than single-ended connections and allow the use of long interconnect cables.  
Balanced connections are completely immune to induced noise from the system  
or the environment.  
CAST and Evolution CAST  
Krell Current Audio Signal Transmission, or CAST, is a proprietary Krell circuit tech-  
nology for connecting analog components, transmitting the audio waveform  
between components in the current domain rather than in the voltage domain. The  
speed and bandwidth provided by Krell CAST and its circuitry update, Evolution  
CAST, yield accurate, realistic music reproduction, enabling connected compo-  
nents to perform as if they are all part of a single circuit.  
Single-ended  
A two-wire input or output circuit. Single-ended connections are not recommend-  
ed for connections requiring long cable runs. Use care when using single-ended  
connections, because the ground connection is made last and broken first. Turn  
the system off/on prior to making or breaking single-ended connections.  
Operation  
Off  
When the back panel power switch (34) is in the down (0) position, or the AC  
power supply cord is disconnected, the component is off, and the stand-by/power  
LED is not illuminated.  
Stand-by  
A low-power-consumption status that keeps the audio and regulator circuits at  
idle. The stand-by/power LED (2) is illuminated in red when the component is in  
stand-by mode. Krell recommends leaving the component in stand-by mode when  
it is not playing music.  
Operation  
When the power button (1) or key is pressed, the standby/power LED (2) is illumi-  
nated in blue, and the component is in operational mode and ready to play music.  
continued

(SECTION ONE: Evolution 505 Features and Technology continued)  
Technology  
Krell Current Mode  
A proprietary Krell circuit topology in which the audio gain stages of a component  
operate in the current rather than the voltage domain. This unique technology pro-  
vides the component with exceptional speed and a wide bandwidth.  
SACD Disc  
A Super Audio Compact Disc (SACD) is an audio disc that provides exceptional  
high quality sound. Based on the new Direct Stream Digital (DSD) technology, a  
format that comprises a 1-bit system, a SACD has a sampling frequency 64 times  
higher than that of a conventional audio CD. With a frequency response of over  
50 kHz, and a dynamic range of 120 dB over the entire audible spectrum, the  
results are spectacular: There is no better audio disc reproduction.  
You will recognize a SACD by the super audio compact disc logo.  
There are three SACD disc types:  
1. A single layer disc consists of one high density (HD) layer.  
2. A dual layer disc consists of two HD layers, and can store twice as much infor-  
mation as a single layer disc.  
3. A hybrid disc consists of one standard compact disc layer with conventional  
two-channel audio compact disc information, and one HD layer.  
SACD Disc: Hybrid Disc Type  
Each SACD disc type may contain two areas of recorded information: a high-quali-  
ty two-channel area and a high-quality multi-channel area. Recorded information  
may vary per area. Refer to the disc inlay for more information.  
The hybrid SACD disc type has the most versatile disc playback options, with two  
areas of recorded information for SACD playback as well as backward compatibili-  
ty with existing standard CD and DVD players via the standard compact disc layer.  
On a hybrid SACD disc, the two layers are read from the same side of the disc.  
The HD layer is read by a DVD laser. The reflective conventional compact disc  
layer is read by the CD laser through the second, semi-transmissive HD layer.  
CDDA  
This is the digital audio file type utilized for standard CD’s. CDDA stands for a  
Compact Disc Digital Audio system.  
Data Disc  
This is a disc composed of digital audio files of a type other than CDDA. The most  
widely recognized non-CDDA digital audio file type is MP3.

(SECTION TWO: Unpacking and Placement continued)  
Placement  
Before you install an Evolution 505 into your system, please follow the guidelines  
in this section to select a location for your component. This will facilitate a clean,  
trouble-free installation.  
The Evolution 505 does not require a special rack or cabinet for installation. The  
preamplifier chassis measures 17.3 in. (43.8 cm) wide, 6 in. (15.3 cm) high, and  
17.3 in. (43.8 cm) deep.  
Place the Evolution 505 on a firm, level surface, away from excessive heat, humid-  
ity or moisture. The Evolution 505 requires at least two inches (5 cm) of clearance  
on each side, and at least two inches (5 cm) of clearance above the component to  
provide adequate ventilation. Installation inside cabinetry may require additional  
ventilation.  
Do not place the Evolution 505 near hum sensitive components such as preampli-  
fier phono stages or turntables. Although the Evolution 505 is well shielded, plac-  
ing it near these components could create interference and cause hum.  
Note  
The Evolution 505 incorporates an advanced suspension system and does not require addi-  
tional mass coupling or isolation. You may experiment with feet or cones as long as they  
are not permanently affixed to the unit. Any unauthorized modifications to the unit or elec-  
tronics will void the warranty.  
IMPORTANT  
Do not attach enhancement accessories such as rings, mats, or dampers to individ-  
ual discs. These accessories may interfere with the disc transport, resulting in erratic  
playback and/or poor sound.  
AC Power Guidelines  
The Evolution 505 has superb regulation and does not require a dedicated AC cir-  
cuit. Avoid connections through extension cords or multiple AC adapters. High  
quality 15 amp AC strips are acceptable. The use of AC line conditioning devices  
or filters may be used if they are grounded and meet or exceed the unit’s power  
supply rating of 100 VA.  
IMPORTANT  
When the internal line fuse needs to be replaced, contact your dealer, distributor or  
Krell. The line fuse is not intended to be replaced by the user.

Connecting the Evolution 505 to Your System  
Using Balanced Connections  
Krell recommends using balanced interconnect cables. Balanced interconnect  
cables can not only 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.

Connection Steps  
Follow these steps to connect the Evolution 505 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 505 and all system compo-  
nents. Separate AC wires from audio cables to prevent hum or other unwanted  
noises from being introduced into the system.  
3. Remember that balanced outputs use three-pin XLR connectors. Single-ended  
outputs use RCA connectors. Maintain the correct left/right orientation of these  
outputs.  
4. To play an SACD, you need to use the analog audio outputs. Digital audio out-  
puts are only available for conventional compact discs.  
For multi-channel SACD (SACD MULTI), two-channel SACD (SACD STEREO), and  
conventional compact disc playback, connect the Evolution 505 multi-channel  
analog audio outputs to the surround preamp/processor multi-channel inputs.  
All multi-channel analog audio outputs are available in the SACD MULTI format.  
The center (C), subwoofer (SW) and surround (SL, SR) multi-channel outputs  
are not available in the CD or SACD formats. The left (L) and right (R) multi-  
channel outputs are always active.  
5. For two-channel and conventional compact disc playback only, connect the  
Evolution 505 balanced analog audio outputs or the left (L) and right (R) multi-  
channel outputs to the preamplifier balanced or single-ended analog audio  
inputs.  
6. For conventional compact disc playback only, connect the Evolution 505 digital  
coaxial output or digital optics output to the corresponding preamp/processor  
digital input.  
7. Plug the AC power cord into the IEC power connector on the back panel. Then  
plug the AC power cord into the wall socket.

Using the Title Button or Key (13)  
Use the title button (13) or key to select one of the three disc formats that the  
Evolution 505 plays: CD (conventional CD), SACD STEREO (two-channel SACD) and  
SACD MULTI (multi-channel SACD). The currently selected format is shown in the  
front panel display (18). The default format for all SACD discs is SACD MULTI.  
The tracks on the selected disc format are the only tracks that can be played. To  
access tracks on alternate disc format, press the title button or key again. If there  
are no tracks in a particular format, that format does not appear in the front panel  
display.  
Perform the following steps in order to access the different formats on a  
hybrid SACD:  
1. Press the stop button (5) or key. The front panel display reads the total tracks  
and time on the disc.  
2. Press the title button (13) or key until the desired format is seen in the front  
panel display. The format name disappears and the front panel display reads  
the total tracks and time on the disc. Press the play (6) button or key to begin  
playing the selected format.  
Note  
The front panel display reads “CHANGING LAYER” whenever you move between the conven-  
tional CD and SACD layers.  
Navigating a Data Disc  
The Evolution 505 is capable of reading MP3 audio files from data discs that you  
prepare on a personal computer. The front panel display indicates ROOT when you  
are at the beginning of the disc, F corresponds to a closed folder, and TOP desig-  
nates an open folder.  
Use the following buttons and keys to navigate within a data disc:  
1. Press the enter button (11) or key to open a folder or move back to a previous  
folder, or to play a track.  
2. Press the up and down arrow buttons (12) or keys to move among tracks in a  
folder.

(SECTION FIVE: Evolution 505 Operation continued)  
Using the Filter Button or Key (17)  
Four filters make subtle changes to the high frequencies at ultrasonic levels, alter-  
ing the sonic presentation from your loudspeakers. Once a filter setting has been  
selected, it is held in memory even if the Evolution 505 is turned off and then  
returned to operational status.  
Filter 1, 2, 3, and 4 are available in any SACD format. Only Filters 1 and 2 are  
available in the conventional CD format. All filters have a different output gain,  
higher bandwidth, and a more gradual rolloff in the SACD format, compared to  
Filter 1 and 2 in the CD format.  
Filter 1 and 2 are designed to eliminate aliasing artifacts that are the result of the  
D/A re-construction process.  
Conventional Compact Disc Format Filters  
Filter 1 operates flat from 20 Hz to 20 kHz, with a very steep roll-off characteristic  
above 20 kHz (21.5 kHz, -3 dB).  
Filter 2 operates up to 20 kHz (-3 dB) with a more gradual roll-off characteristic  
when compared to Filter 1.  
SACD Format Filters  
Filter 1 in the SACD format, has the same relative output gain as Filter 1 and 2 in  
the CD format, and it has the highest bandwidth of the four SACD filters. Filters 2,  
3 and 4 in the SACD format, operate at reduced bandwidth with steeper slope fil-  
tering and different output gain.  
Filter 1 operates up to 180 kHz (highest bandwidth) and has the slowest roll-off  
characteristic with no change in output gain.  
Filter 2 operates up to 75 kHz and has the steepest roll-off characteristic. It has a  
+0.5 dB increase in output gain over the entire audio pass band compared to  
Filter 1.  
Filter 3 operates up to 80 kHz and has the 2nd steepest roll-off characteristic. It  
has a +5.5 dB increase in output gain over the entire audio pass band compared  
to Filter 1.  
Filter 4 operates up to 90 kHz and has the 3rd steepest roll-off characteristic. It  
has a +3.5 dB increase in output gain over the entire audio pass band compared  
to Filter 1.

Using the Repeat Key (22)  
Press the repeat key once to repeat the current track. The front panel display (19)  
reads REPEAT SINGLE. Press the repeat key twice to repeat the whole disc. The front  
panel display reads REPEAT ALL. Press the repeat key a third time to cancel this  
function.  
Using the Repeat A/B Key (23)  
To create an A/B loop, start by playing a track. When you hear the part that you  
want as the beginning of the loop, press A/B to insert the start position. Press A/B  
again to insert the finish position. A/B playback will automatically begin and will  
continue indefinitely. To delete, press A/B again, or press the stop button (5) or key.  
Using the Front Panel Display (19)  
The front panel display shows the disc type, the elapsed time of the track, and the  
feature that has been selected, for example: REPEAT ALL or REPEAT SINGLE. Press the  
display button (21) or key to show track time remaining, disc elapsed time, or disc  
time remaining. Press the dim button (20) or key to reduce the brightness of the  
display.  
Using the 12 V Trigger (31)  
This function allows you to turn other components on or off, or to and from stand-  
by, from the Evolution 505. When the Evolution 505 is switched between stand-by  
and the operational mode, the 12 V trigger sends a signal from the 12 VDC Out  
that will switch other components, allowing whole systems or parts of systems to  
be easily coordinated.  
The 12 VDC input allows you to turn the Evolution 505 on or off, or to and from  
stand-by, from other components.  
Note  
When the component is in the operational mode, the 12 VDC Out provides 12 V of DC out-  
put. When the component is in the stand-by mode or off, the DC output is 0 V. The 12 VDC  
output current is limited to 30 mA. Consult the owner’s reference of the components used  
in a custom installation to take full advantage of the remote capability of the Evolution 505.  
Using the RS-232 Port (32)
