Unpacking
Be careful when unpacking your 903, it is heavy. Seek assistance if necessary. Store the packaging safely for future use. It is
the ideal method of protecting your 903 from damage during transport.
Environment
Do not site the 903 near liquids, or place liquid-lled containers near the unit. If liquid does come into contact with the
unit there is serious potential for an electric shock or re hazard. Immediately pull out the mains plug from the wall socket.
Contact your dealer to arrange an inspection before further use.
The 903 is cooled by convection and so needs good circulation of room temperature air, both under and around it. Do not
place it near sources of heat such as radiators or in direct sunlight. Do not enclose in a cupboard. Do not place directly on
carpet.
A at, smooth surface is required. As with all high resolution audio equipment, your 903 is sensitive to vibration, strong
magnetic elds and radio interference. A dedicated, high performance equipment platform sited away from other appliances
is the optimum location.
Power Supply
The AC input voltage has been set for the country where it was purchased. Check that the label on the rear panel matches
your AC supply voltage before connecting the supply. The provided AC inlet cable should be used.
The 903 must be earthed through the IEC inlet connector. Do not disconnect the AC earth at any time. If in doubt about any
aspect of power supply, consult your Trilogy dealer or a qualied electrician.
To realise your preamplier’s full potential we recommend high quality mains conditioning. See www.Isol-8.co.uk for more on
power supply and system solutions from our highly acclaimed sister company. If you are not using a mains conditioner for
best performance, make a direct connection to a mains outlet. Avoid using adapters where possible.
The IEC inlet provides the unit with power. Connect with the supplied AC input cable. It can be left connected at all times
to ensure reliable operation. If not being used for extended periods of time, switch off at the mains outlet or the rear panel
power switch. The 903 carries internal fuses for protection which are not user replaceable. If the standby indicator does
not light when power is applied and power has been tested and available on the cable IEC socket, return the unit to an
authorised Trilogy dealer for servicing.
