Introducon
Thank you for choosing the CP1 to be a part of
your high performance music listening system.
Each CP1 is handcraed, using the very latest,
no compromise, cung edge technology and
componentry. This ensures the best possible
sound reproducon currently available and
guarantees many years of listening enjoyment.
We understand that you are eager to begin
listening; however, please take a few minutes to
read through this guide for useful informaon
concerning the operaon of your new preamplier.
OAD Ultradelity equipment takes a considerable
me to run in before it performs at its best. The
duraon varies, but under some condions the
sound may connue to improve for over a month.
Beer and more consistent performance will be
achieved if the system is le switched on for long
periods. It is worth remembering however that
equipment le connected to the mains can be
damaged by lightning.
Aer reading this manual, if you have any further
quesons regarding your preamplier, contact
your dealer or OAD Ultradelity customer service
– they will be happy to help you to make the most
of your new component.
Happy Listening!
Warnings
• To prevent re, or shock hazard, do not expose
your CP1 to rain or moisture.
• Do not place objects containing water on top
of this unit.
• This unit contains voltages which can cause
serious injury or death.
• Do not operate with covers removed. Refer
servicing to your authorized OAD Ultradelity
dealer or service personnel.
• A power cord is shipped with your CP1 that
meets the required safety standards. It is
important for both safety and performance
that the standard cable supplied is not
modied.
• A switch at the rear of the CP1 must be
accessible in case of emergency power
disconnect. The power buon on the front
touch display panel of this unit, when o,
does not disconnect all power from this unit.
This unit is in standby mode when not on.
For connued protecon against re hazard,
replace the fuse only with the same type and
rang (see page 8 for fuse informaon).
• Your hi- system, including the CP1, can be
damaged by lightning and should be turned
o and disconnected from the mains when
there is risk of lightning strike.
• We recommend that all connecons to the
CP1 are made with either the mains power
cord disconnected or the rear mains switch le
in the ‘0’ (OFF) posion. When all connecons
are made and checked, move the rear mains
switch to ‘1’ (ON) posion.
Venlaon
Due to its highly sophiscated ve power supplies,
the CP1 will run slightly warm when not in standby.
You must allow for this in installaon, by providing
for free air circulaon around the product. Never
block any venlaon openings. Allow at least 50
mm of clearance around these products for proper
venlaon. Electronics should not be subjected to
sources of excessive radiant heat. Excessive heat
can shorten the life of the product.
Packaging
Save all packaging in a dry place away from
re hazard. Your CP1 is a precision electronic
instrument and should be properly boxed any me
shipment is made. It is very unlikely that you will
have to return your unit to the factory for service,
but if that should prove necessary, the original
packaging will protect your CP1 from unnecessary
damage or delay.
Interconnect Cables
RCA/Phono Interconnect plugs and sockets should
be kept clean and free from corrosion.
The CP1 is ed with silver plated oxygen free
copper input and output sockets that will tarnish
over me. Tarnished or oxidised silver does not
degrade the quality of contact. This is a disncve
property of silver plang. If you wish to clean the
connectors, switch o the equipment, pull the
plugs out of their sockets, and push them back in
again. Contact cleaners and “enhancers” should
not be used as the lm they deposit may leave a
deposit and degrade the sound.

Idencaon of Connecons & Controls REAR PANEL
1 AC MAINS INPUT
• The CP1 comes supplied with a detachable mains power cord. Connect corresponding end of the
mains power cord to the AC mains input of CP1 and the plug connected to a mains power source.
• Always disconnect the mains power plug from the mains power source rst, before disconnecng the
cable from the CP1’s AC Mains input socket.
2 POWER SWITCH
• Supplies the AC mains power to the CP1.
• When the POWER switch is set to ON (1) posion, the CP1 will run through its boot up procedure and
within 30 sec will be ready to play.
• If you do not intend to use the CP1 for long periods of me (such as when on holidays), switch o (0)
the POWER switch. With POWER switched o, neither the front touch panel display (Standby) buon
nor the remote control’s power buon can acvate the CP1.
3 FUSE HOLDER
• Your CP1 is ed with a fuse. If it needs to be replaced you must use the same type and rang. Installing
an incorrect fuse may cause damage and this will void the warranty of your CP1.
4 AUDIO OUT
• The main outputs that connects the CP1 to the corresponding audio inputs of external power ampliers.
5 AUDIO IN
• Use single-ended analog audio input for sources (CD Player, tuner, DAC or other applicable devices).
• If your CP1 has the oponal PHONO card installed then connect the twin RCA lead from your turntable
to INPUT 1.
6 PHONO GROUND CONNECTOR
• Turntables normally include a single wire earth lead. Use the CP1 phono ground connector to connect
this lead. Unscrew the terminal to connect the earth lead. Tighten the terminal to secure the lead.
7 & 8 PHONO DIP SWITCHES
• Adjust switches to suit your type of MM cartridge, gain level and parallel capacitance. See pages 8 & 9.

Introducon
The CP1 phono card gives vinyl playback with the lowest noise gure possible. The phono card is able to
play extremely low output moving coil (MC) cartridges without a step-up transformer. The extremely low
noise and high gain design of the phono card is capable of cleanly and quietly delivering a line level signal
output with a phono cartridge input of down to 80 micro-volts.
Cartridge loading is automac when connecng a MC cartridge due to its unique design. For moving
magnet (MM) cartridges, parallel capacitance loading is provided for. Parallel capacitance can be adjusted
from 100 pF to 750 pF.
Adjustment of switches
Adjustment is to be made with the CP1 switched o or beer sll with your power amplier switched o.
Changes made to the phono card loading have the possibility of sending pulses to your power amplier
that could damage speakers if the volume of the preamp is set suciently high.
On the rear panel you will see two sets of DIP switches. These switches allow you to select cartridge type
(moving magnet or moving coil), select gain, and adjust cartridge loading.
Just above these DIP switches you will see graphic representaon of how the two pairs of switches can be
adjusted. Switches 6,7 & 8 of DIP switch on the right have no eect and should be ignored. The phono card
ships from the factory with a default seng of moving coil at 100 ohms with a gain of 71 dB.
In order to set the switches for your parcular cartridge, you will need to have some knowledge of its
specicaons. If you do not have that cartridge informaon, please contact your dealer or OAD directly.
We will aempt to help you with that data, however we do not have factory data on every cartridge ever
built. Select Moving Magnet (MM) or Moving Coil (MC) according to the type of cartridge you have. In all
instances the switch-tab for any selecon will need to be down for ‘on’ and up for ‘o’.
Gain seng (G)
The gain control aenuates the overall gain of the phono card stage in such a way that when the gain is
reduced, the noise levels seen at the output of the CP1 are reduced proporonally. In this way, there is no
penalty in selecng one gain seng over another. The exemplary signal, distoron and noise gures of the
CP1 are never compromised by changing gain sengs.
Choose a gain seng that allows the volume control to operate within a range similar to that of your other
source components. If phono is your only source component, then pick a gain seng that allows your
preamp a fairly advanced gain seng at whatever you consider to be a comfortable listening level. In most
cases, set gain switch up for MC cartridges and down for MM cartridges.
Moving Coil setup
For MC cartridges, switch 4 (MM) of both DIP switches are set to up for ‘o’.
In MC mode, parallel capacitance is switched out and has no eect.
All technical specicaons are subject to change without prior nocaon.

9
Depending on the output voltage of your MC cartridge, you may need to adjust DIP switch 5 (G). Up will
set the phono card to 71dB and down will set the gain to 61dB. For most MC cartridges, the higher gain
seng will be necessary to achieve normal listening levels.
Moving Magnet setup.
For MM cartridges, switch 4 of both DIP switches are set to down for ‘on’.
It will be impossible to give suggesons for correct capacitance with any given cartridge, due to the huge
variaon in capacitance of turntable cables. The opmal value is selected by listening.
There are three capacive loading switches with values of 100pF, 220pF and 330pF. These are in addion
to a xed value of 100pF. You may select any switch or number of switches; the values are addive. The
range of values available is 100pF – 750pF. The correct value is that which gives the best overall tonal
balance. Typically, if the cartridge sounds too bright, then more capacive loading is required. Set switches
1,2 & 3 of both le and right DIP switches to the same posions when seng the parallel capacitance. For
most MM cartridges, the lower gain of 35dB will be the preferred seng.
Resisve loading for moving magnet is xed at 47kOhm. If you require something other than 47kOhm,
please contact the OAD factory.
Do not set the preamp so that it enhances one recording only. Listen to a variety of material and adjust
accordingly.
