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

The Evolution 505 has Class A, balanced, Krell Curr
to output for increased bandwidth. New current mirror stages feature LED voltage
reference. Developed for the Evolution Two, these current mirrors operate with

ee times less distortion than previous designs. A zero feedback design pre-

thr
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 supe­rior 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), DVD­R, RW, +R, and RW discs. The 16 character, dot-matrix LED display is highly visi­ble and features an adjustable intensity.

For flexibility of control, the back panel features a 2-way, RS-232 interface, an
RC-5 connector

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 characteris­tics that act upon the musical signal independently
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 inter­connects into an electrically-linked whole. The original signal remains unalter
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

How CAST and Krell Current Mode Interact

While CAST is a new method of transferring the musical signal between compo­nents, its origin stems from Krell Current Mode, the technology developed to
transfer the musical signal within a component. CAST combined with Kr
Mode takes cir

cuitry signal transmission to the next evolutionary level.

(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 compo­nents into a

single global circuit. Krell Current Mode technology enjoys bandwidth

increases up to an order of magnitude greater than their voltage based counter­parts. 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 spe­cially licensed by Krell. Thin and flexible CAST cables ar
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 ar

By employing radical current mirror circuitry, the Evolution 505 components ele­vate the CAST technology to another level. This advanced use of the technology
increases the linearity, transient speed, and bandwidth of the Evolution compo­nents while reducing the distortion by an or

der of magnitude.

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 profes­sional 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 tech­nology for connecting analog components, transmitting the audio waveform
between components in the curr
speed and bandwidth provided by Krell CAST and its circuitry update, Evolution
CAST, yield accurate, realistic music reproduction, enabling connected compo­nents 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 recommend­ed 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.

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 pro­vides 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 T

ype

Each SACD disc type may contain two areas of recorded information: a high-quali­ty 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 compatibili­ty 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.

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 r

ecognized 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, humid­ity 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 preampli­fier phono stages or turntables. Although the Evolution 505 is well shielded, plac­ing it near these components could create interference and cause hum.

Note

The Evolution 505 incorporates an advanced suspension system and does not require addi­tional 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 elec­tronics will void the warranty

IMPORTANT
Do not attach enhancement accessories such as rings, mats, or dampers to individ­ual 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 cir­cuit. 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.

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) multi­channel 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) multi­channel outputs to the pr

Using the Filter Button or Key (17)

Four filters make subtle changes to the high frequencies at ultrasonic levels, alter­ing 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 incr

ease in output gain over the entir

e 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 incr

ease in output gain over the entir

e audio pass band compar

ed

to Filter 1.

Filter 4 operates up to 90 kHz and has the 3r

d steepest roll-off characteristic. It
has a +3.5 dB increase in output gain over the entire audio pass band compared
to Filter 1.

This function allows you to turn other components on or off, or to and from stand­by, 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 out­put. When the component is in the stand-by mode or off, the DC output is 0 V
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.
