INTEGRIS CDP – Owner’s Reference Guide

1
Introduction
Thank you for your purchase of the Integris CDP Compact
Disc Player and Linestage Preamplifier. This Owner’s
Reference Guide contains information that will permit you
to obtain maximum performance and utility from the
Integris CDP’s extensive features.
Unpacking and Repacking
Do not discard any packing materials! You will need them
to transport the unit, should that be necessary. Shipping
without all proper packaging materials may result in
damage.
.
1. Open the box along the top flaps and remove the
top section of protective foam. Remove and set
aside the bubble envelop of small parts.
2. Reach around the sides of the unit and lift straight
out of the shipping box.
3. Remove the unit from its clear poly bag without
tearing the bag. Placing it on a soft but secure
surface can make removal easier.
4. Remove the transport bay foam insert. You may
wish to leave it in place until the unit has been
placed in its final location – this will keep the lid in
place during any further movement of the unit.
5. Carefully open one end of the small-parts bubble
envelope and remove its contents:
•Magnetic transport disc clamp
•Integris R-676 remote
•4 AAA alkaline batteries
•USB cable
Remove all items from their sub-packaging. Place
the small item packaging back in the bubble
envelope.
6. Place the small-parts envelope, transport foam
insert, and the box’s top foam section back inside
the box. Close the box and store in a dry area.
Placement
The Integris CDP employs a top-loading CD transport that
requires sufficient space above it for a user to comfortably
load and remove discs and the disc clamp. Ideally the
Integris CDP should be placed on a top shelf or where a
generous clearance exists.
For optimal placement, put the Integris CDP on a firm level
shelf away from heat, humidity, moisture, and vibration.
Avoid direct exposure to sunlight.
While stacking components on top of the Integris CDP is
not possible, if necessary, the unit may be placed on top
of other components. The user should be certain that any
supporting components provide a stable and inert
platform.

8. CD Scan/Skip Reverse (REV)
9. CD Scan/Skip Forward (FF)
These buttons enable two functions during CD playback:
•Track Skip – Apply a momentary contact of
approximately ¼ second or less to the REV or FF
buttons to have the transport return to the beginning
of the track already playing (REV) or advance to the
beginning of the next track (FF). Press repeatedly to
skip by several tracks.
•Scan – Hold either button down for 1 second or more
to move within a track. Initial scanning rate is 3X
normal speed and increases to 15X when held for
several seconds. One of the reverse or forward scan
symbols, <<<, <<, >>, >>>, will appear on the display.

12. Menu (MENU)
The MENU button accesses a sophisticated set of user-
customizable features:
MENU setup areas
Input Name Setting
Analog Level Trim
Volume Control Bypass
Preferences Save and Reset
These are extensively explained in the MENU – Optional
User Settings section of this Guide.
13. Volume Up (VOL +)
14. Volume Down (VOL -)
VOL+ and VOL- will incrementally raise or lower the
preamp volume control within a range of -60dBu to
+20dBu. Lowering the volume to below -60dBu mutes the
circuit: the display will provide a VOLUME MUTE message.
In normal use, the Volume setting is always shown on the
top line of the display regardless of Input selection.
During adjustment, a visual volume bar-scale appears
temporarily on the display’s bottom row to further aid in
setting the volume level:

Single presses of the VOL buttons will result in changes
relative to the Volume setting range:
Volume range Setting Change
-20 to +20 dBu 0.5dB
-40 to -20 dBu 1.0dB
-60 to -40 dBu 2.0dB
Holding the buttons continuously will temporarily increase
the size of the volume control increments to allow for
rapid volume adjustment.
15. Balance Left (BAL L)
16. Balance Right (BAL R)
Each press of the BAL L or BAL R buttons decreases the
opposite channel output in 0.5dB increments. From a
nominal center balance position of 0dB, the maximum
cut is -6dB. Pressing beyond -6dB puts the lowered
channel into full MUTE mode. To restore the balance
toward the nominal center position or beyond, press the
opposite balance button.
Balance settings are held on the display for two seconds,
and appear such as this example for a reduction in Left-
channel output:

Back Panel Features and Definitions
1-4 Mains Power Panel
The Integris CDP is designed for use with all major AC
power systems. The unit has built-in RFI filtering for
superior performance.
1. Mains Power Inlet
A power cord with an IEC 10-15Amp female plug is
required to connect AC power to the Integris CDP. We
recommend quality aftermarket power cords and direct
connection to a quality AC outlet for best performance.
2. Power Switch
The mains rocker switch illuminates in the On position.
The mains switch may be used to isolate all of the Integris
CDP’s internal circuits from AC power.
3. Mains Power Fuse – ¼A
The fuse is a 0.25 x 1.25 inch slow-blow type rated at
1/4Amp/250V. Replace only with the same type and
value.
4. Voltage Selector
Confirm that the voltage selector is set to the nearest
standard voltage in your area. All products should be
delivered preset to the correct voltage but exceptions
can occur. Do not connect power until you are certain
of the correct voltage setting.
5-9. Analog Preamp Inputs
The analog preamplifier section of the Integris CDP has
five line-level buffered Inputs. Highest quality
components are used to allow external sources to
achieve their maximum potential.
5-7. Unbalanced Inputs 1-3
These three inputs accept signals via unbalanced RCA-
equipped interconnect cables, the most common type
in use. The Integris CDP’s RCA jacks are premium high
performance components from cabling specialist Cardas
Audio.
8-9. Balanced Inputs 1-2
These two inputs accept signals via balanced XLR-
equipped interconnect cables.
10-14. Digital Inputs
The Integris CDP has five digital inputs that accept PCM
(pulse code modulated) signals from 32kHz-192kHz at 16-
24 bit word length for two-channel playback. Examples
of these sources include CD transports, DVD-Audio, DAT
decks, and many PC-based applications. All digital
inputs are routed through the Quantum resampler and
Delivered to the onboard DAC (digital to analog
converter) at a sample rate of 24 bit/192kHz.
Switching off power will reset all user-
configurable operating parameters to
factory default or to the last saved user-
settings, if present.

10-11. S/PDIF 1-2
These connections accommodate the most common
digital interconnect interface using RCA-connector
equipped cables and 75ohm load impedance. These
Inputs also accommodate PCM sample rates different
than the S/PDIF standard of 16 bit/44.1kHz.
12. BNC
This connection is essentially the same as S/PDIF 1-2 but
with an alternate cable connector, the BNC.
13. AES/EBU
This is a balanced digital connection, as found on some
digital sources requiring an XLR equipped digital
interconnect and 110ohm load impedance.
14. TOSLINK
This input allows connection to a source with Toslink (EIAJ)
optical transmission of the standard S/PDIF digital signal.
15-16. Digital Outputs
The digital outputs are monitoring loops that allow return
of the digital signal input to the source or to a secondary
component or system.
These signals are returned at the native sampling rate at
which they are received: Quantum resampling is not
applied. The internal CD transport is available from these
outputs at the standard sampling rate of 16 bit/44.1kHz.
15. S/PDIF
This connection accommodates the most common
digital interconnect interface using an RCA-connector
equipped cable and 75ohm load output impedance.
16. TOSLINK
This output allows connection to a receiver with Toslink
(EIAJ) optical transmission.
17-18. Analog Outputs
The preamplifier’s analog outputs are capable of
properly driving virtually all audio power amplifiers. Their
buffered outputs provide low output impedance and
high current capability to drive both high- and low-
impedance loads. All signals are managed by the
volume control circuit unless the Volume Control Bypass
feature is enabled – see the MENU – Optional User
Settings section. Balanced and unbalanced signal
outputs may be used individually or simultaneously.
17. Balanced Outputs
This connection type, requiring XLR-equipped analog
interconnects, is recommended when connecting to
power amplifiers with fully-differential circuits. It may also
be preferred in EMI/RFI prone environments or for
especially long cable runs.
18. Unbalanced Outputs
This connection type, requiring RCA-equipped analog
interconnects, is the most common cable and connector
Non-PCM signals are not accommodated: these
include DSD and other one-bit formats as well as
compressed formats such as MP-3 and Dolby
Digital.

type found on audio amplifiers. These outputs, using
connectors from Cardas Audio, provide a very high level
of performance in most situations.
19-20. Upgrade Potential
Aurum Acoustics has designed the Integris CDP to be
modular, expandable, and upgradeable. The internal
digital and analog systems are designed for possible
upgrades and enhancements. Other new hardware
and software applications may be created for the
Integris CDP to increase its performance and utility. With
the COM Port and Expansion Panel, the user will have the
option to self-install new offerings. Check
www.aurumacoustics.com and with your Aurum
Acoustics retailer for developments.
19. COM Port
Firmware upgrades can be made via connection of this
RS-232 serial port to a PC. As needed, Aurum Acoustics
will make available software and instructions allowing the
user to execute a firmware update. Presently there are
no user-accessible features serviceable via the COM
Port.
20. Expansion Panel
The area behind the expansion panel is presently an
unused space available for adding new hardware
options. Aurum Acoustics may develop high
performance accessory modules permitting even
greater integrated capabilities from within the Integris
CDP platform.
