Introducon
Thank you for choosing the UP1 to be a part of your high performance music listening
system. Each UP1 is handcraed, using the very latest, no compromise, cung edge
technology and componentry. This ensures the best possible sound reproducon 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 informaon concerning the operaon of your new
phono amplier. OAD Ultradelity equipment takes a considerable me to run in before
it performs at its best. The duraon varies, but under some condions the sound may
connue to improve for over a month. Beer 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.
Aer reading this manual, if you have any further quesons regarding your preamplier,
contact your dealer or OAD Ultradelity 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 UP1 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 Ultradelity
dealer or service personnel.
• A power cord is shipped with your UP1 that meets the required safety standards. It
is important for both safety and performance that the standard cable supplied is not
modied.
• Your hi- system, including the UP1, 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 connecons to the UP1 are made with the mains power cord
disconnected.
Packaging
Save all packaging in a dry place away from re hazard. Your UP1 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 UP1 from unnecessary damage or delay.
Interconnect Cables
RCA/Phono Interconnect plugs and sockets should be kept clean and free from corrosion.

Seng up your UP1
The UP1 gives vinyl playback with the lowest noise gure possible. The UP1 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.
Parallel capacitance can be adjusted from 100 pF to 420 pF.
Adjustment of switches
Adjustment is to be made with the UP1 switched o, or beer sll, with your power
amplier switched o. Changes made to the phono card loading have the possibility of
sending pulses to your power amplier that could damage speakers if the volume of the
preamp is set suciently high.
On the rear panel you will see two pairs of DIP switches (DIP10 & DIP4) for both le and
right channels. These switches allow you to: select cartridge type (moving magnet or
moving coil); select gain; and adjust cartridge loading.
A graphic representaon of how the two pairs of switches can be adjusted is printed on the
rear panel of the UP1. The UP1 ships from the factory with a default seng of moving coil
at 100 ohms with a gain of 70 dB.
In order to set the switches for your parcular cartridge, you will need to have some
knowledge of its specicaons. Select Moving Magnet (MM) or Moving Coil (MC) according
to the type of cartridge you have. In all instances the switch-tab for any selecon will need
to be up for ‘on’ and down for ‘o’.
Gain seng
The gain control aenuates 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 UP1 are reduced
proporonally. In this way, there is no penalty in selecng one gain seng over another.
The exemplary signal, distoron and noise gures of the UP1 are never compromised by
changing gain sengs.
Choose a gain seng 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 seng that allows your preamp a fairly advanced gain seng 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, DIP10 switch 1 is set to ‘on’ for 60dB of gain. For addional gain in 5dB
steps, select ONLY one DIP4 switch to set the overall gain to either 65dB, 70db, 75dB or
80dB.
In MC mode, parallel capacitance is not recommended. Set DIP10 switches 9 and 10 ‘down’
to remove the eects of any added capacitance.
DIP10 impedance seng switches 2 to 8 should be set to your cartridge type as specied
by the manufacturer.
Moving Magnet setup
DIP10 impedance seng switches 2 to 8 are set ‘down’ to give an impedance of 47K Ohm.
DIP10 switch 1 is set ‘down’ for a MM gain of 40dB. For addional gain in 5dB steps, select
ONLY one DIP4 switch to set the overall gain to either 45dB, 50db, 55dB or 60dB.
