Introduction
We prefer that your Trilogy dealer delivers, installs, sets up and explains your 906’s operation to you.
However, we still recommend that you read through this manual thoroughly and keep it to hand for
reference.
Should any part of this manual or the operation of the 906 not be clear to you, please do not hesitate to
contact your Trilogy dealer. If they are not available please contact ourselves directly.
Unpacking
Be careful when unpacking your Trilogy 906 Phono Stage. Store the packaging safely for future use. It is
the ideal method of protecting your 906 from damage during transport.
Environment

out the mains plug from the wall socket. Contact your dealer to arrange an inspection before further use.
The 906 generates a small amount of heat and is cooled by convection. Do not place either unit near
sources of heat such as radiators or in direct sunlight. Do not enclose in a cupboard. Do not place directly
on carpet.

Conguration

switches for this purpose. The switches are marked 1 to 6 with an “ON” to give indication of directionality.
They are independent for each channel and must be set the same for left and right channels.
Your phono cartridge will have an optimum working load which should be provided by the cartridge
manufacturer. It is expressed in resistance (R or Ohms) and capacitance (pF or pico Farads). It will also

Connections
It is good practice to complete all interconnections before switching on to avoid any damage to your
loudspeakerswhilepluggingin.Doublecheckthephonopreamplier’scongurationswitchesbefore
connecting to your system.
The rear panel features 4 RCA phono sockets. Connect the phono plugs from the turntable’s cartridge
to the left and right sockets marked “INPUT”. The 906 outputs should be connected to a suitable
preamplier.Doublecheckleftandrightchannelsareconnectedcorrectly.Ifaturntablearmearth
connection is provided, it can be connected to the earth binding post adjacent to the sockets. Other arm
cable connector types will require an adaptor; seek advice from your Trilogy dealer.
Power Supply
The AC input voltage has been set for the country it was purchased in. Check that the label on the rear
panel matches your AC supply voltage before plugging in. The AC inlet cable provided should be used. If
another cable is used check it is wired correctly and fused appropriately.
The wires in the AC input cable supplied are coloured in accordance with the following code:
Green and yellow: Earth
Blue: Neutral
Brown: Live
WARNING! The 906 must be earthed. Do not disconnect the AC earth at any time. If in doubt about any
aspectofpowersupply,consultyourTrilogydealeroraqualiedelectrician.

on power supply and system solutions from our highly acclaimed sister company.
The IEC inlet carries a ceramic 20mm fuse. If the unit stops working, check and replace this fuse with
one of the same type and value if necessary: 250mA T for 230V version, 500mA T for 100V and 120V
versions. If the fuse repeatedly fails, do not use the unit and contact your Trilogy dealer for service.
WARNING! Failure to replace the fuse with the same type and rating will invalidate the warranty
and may result in an electric shock and/or fire hazard.

As with all high resolution audio equipment, a period of break in is required before the unit will achieve its
full performance potential.
As the 906 consumes little power, we recommend leaving it powered permanently for optimum
performance.

Cleaning
Dust the unit regularly with a soft cloth or soft brush. For more stubborn marks make sure the unit is
switched off and disconnected from the power supply. Use a slightly damp cloth with a very small amount
of mild detergent such as washing up liquid. Do not use a wet cloth.
Becarefulwhencleaning.Neveruseabrasivesoralcoholbasedagents,theywillharmthesurfacenish.
Do not allow the unit to become wet when cleaning.
Servicing
Your 906 has been designed to provide a lifetime of reliable service and should not need servicing if
operating normally.
There are no user serviceable parts inside. Do not open or attempt to repair the unit. Refer to your
authorised Trilogy dealer for repair if necessary.
Declarations
This product is guaranteed against defects in material and workmanship for 3 years from the date of
purchase. Proof of purchase is required.
The Guarantee is not transferable and is offered to the original purchaser only. This guarantee does not
limit your statutory rights within the country of purchase.
Failure to comply with any of the above instructions during installation or operation will render the
manufacturer’s warranty null and void.
Marking by the “CE” symbol (shown left) indicates compliance of this device with the EMC
(Electromagnetic Compatibility) and LVD (Low Voltage Directive) standards of the European Community
The 906 has been tested to ensure that its operation is not adversely affected by normal background
levels of radio frequency interference, and that it does not itself generate excessive amounts of radio
frequency energy.
If your 906 exhibits sensitivity to nearby radio frequency devices or is suspected of affecting another
device, increase the distance between them. If the problem persists, consult your Trilogy dealer.

Glossary
AC
Alternating current: The electrical
polarity reverses over time. Used
mostly for high voltage power
transmission such as mains.
Gain

power or amplitude of a signal from the
input to the output.
Burn In
Period of time which a new
assembly takes to reach mechanical
and electrical equilibrium.
Magnetic
Field
An expression of electromagnetism.

Cartridge
Loading
The electrical termination the phono
cartridge “sees” when connected.
Resistance
The degree to which an element opposes
an electric current through it.
Capacitance
The ability to hold an electrical
charge, resulting in decreasing
impedance with frequency.
Shunt Voltage
Regulator
A circuit which provides a constant
voltage for a load using a constant current
source to provide the current and a
control element that regulates the voltage
across the load.
DC
Direct current: The electrical
polarity is constant. Used mostly for
powering active circuits.
Series Voltage
Regulator
A circuit which provides a constant
voltage for a load using a control element
in line with the power rail and the load.
