SAFETY TIPS
In order to obtain the highest possible sound reproduction quality and for the sake of your own safety, please kindly refer to the following
- Never place the preamplifier near heat sources, such as radiators, heaters or direct sunlight. Ensure adequate ventilation and airflow
- We also warn against exposure of the preamplifier to conditions such as very low temperatures and/or high humidity.
- The preamplifier should be plugged directly into a wall socket. If you must use an extension cord, please make sure that it has load parameters sufficient to ensure proper handling of current delivery to the device.
- When cleaning, always disconnect the preamplifier from the power source. Use a dry, soft cloth. Do not use water or cleaning agents.
- If your preamplifier starts to misbehave or to work incorrectly, if it’s temperature gets too high or you start feeling smoke – immediately disconnect the device from the mains.
- Due to the risk of exposure to high voltages
- please do not open the lid of the preamplifier. ATTENTION: This warning remains in force also in a situation where the device is already disconnected from the wall outlet.
- Always replace fuses in accordance with the original, intended specification.
- Do not make repairs on your own, or adjustments beyond those as described in this manual. Execution of any unauthorised repairs or modifications of the device result in a loss of warranty

To avoid electrostatic shock to the components of the amplifier, please touch a grounded conductive surface before making any connections .Any and all connections must be made whilst the device is disconnected from the mains power supply. Before making any such connections, make sure that the amplifier is switched off.
Follow the instructions below to connect your sound system correctly.
STEP 1 INTERCONNECTIONS
Connect the record player equipped with MM/MC HO cartridge to the MM INPUT of
the phonon stage. If your record player is equipped with MC cartridge, press
GAIN switch at the back panel of the phonon stage.
Connect the earthing wire to the screw terminal GND in phonon stage.
Connect the OUTPUT of the phonon stage to a line input (AUX, CD, Tuner, Tape
or Video) on your amplifier.
Make sure that the amplifier is switched off. Connect the power cord to the
IEC socket on the rear panel of the phonon stage.
The phonon stage is designed to operate at a switched voltage of 110-120V and 230-240V/ 50-60Hz. Please check parameters of your mains network, if needed switch to right voltage using switch at the back . Please ensure that you have installed suitable fuse for desired voltage. Connecting the device to a mains network with incorrect parameters can lead to damage that is not covered by manufacturers warranty. Gaia Prestige phonostage is equipped with audio ground loop switch. If you will have problem with excessive hum, please switch ground loop switch to ON or Off position.
STEP 2 / POWER CORD CONNECTION
Make sure that the preamplifier is switched off. Connect the power cord to the
IEC socket on the rear panel of the preamplifier.
The preamplifier is designed to operate at a rated voltage of 110-120V and
230-240V/ 50-60Hz. Connecting the device to a mains network with incorrect
parameters can lead to damage that is not covered by manufacturers warranty.
GET TING STARTED
Make sure all cables are connected as described above. Select the signal
source using the selector located on the front panel of your amplifier. Set
the volume knob to minimum. Power on the Gaia Prestige preamplifier. Make sure
the turntable is turned on and gradually increase the volume with the volume
knob at your amplifier.
Please chose optimal settings at the preamplifier which suits to your phonon
cartridge
VACUUM TUBE REPLACEMENT
Power down the equipment and unplug it from the electrical outlet. This step
is crucial to prevent electric shock or damage to the device. Vacuum tubes can
become very hot during operation. Allow sufficient time for the tubes to cool
down before attempting to handle them.
Fezz Gaia Prestige is equipped with two 12AU7/ECC82 vacuum tubes. You can
easily change the tube by gently pushing and moving sideways Plexiglas window
at the top of the device. You can move it to the left or right side. Carefully
remove the vacuum tube from its socket. Take the replacement tube and align
the pins with the socket. Gently push the tube into the socket, ensuring that
each pin goes into its corresponding hole. Carefully double-check all
connections to ensure that the new tube is properly seated in the socket, and
none of the pins are bent or misaligned. Once you’ve replaced the tubes and
confirmed all connections, close the Plexiglas window, power up the equipment
and check for proper operation. If there are any issues, double-check the
tubes placement and connections.
