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 turn on the amplifeir without installed tubes and without hooked-up spekers.
- Never place the Fezz Audio Titania amplifier near heat sources, such as radiators, heaters or direct sunlight. Ensure adequate ventilation and airflow
- We also warn against exposure of the amplifier to conditions such as very low temperatures and/or high humidity.
- During normal operation, the vacuum tubes radiate significant amounts of heat – there is a risk of burns.
- The amplifier 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 Titania amplifier from the power source. Use a dry, soft cloth. Do not use water or cleaning agents.
- If your amplifier 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 amplifier.
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 unauthorized repairs or modifications of the device result in a loss of warranty.
INTRODUCTION
New version of extremely powerful and dynamic Titanic amplifier. In standard equipped with anti-vibration feet, adapted to the weight of the device. Backlight logo. Easily accessible fuses protecting the amplifier in case of a power tube failure. Sounds openly and with gusto, yet with a remarkably neutral tone. Constitutes a reference, a benchmark in the area of tight bass control, and positioning of the virtual sources. Titanic – This is simply a Titan of Sound.
INSTALLATION
UNPACKING
Please kindly check if the packaging of the amplifier has not been damaged during transit. If you find any damages, please immediately contact your dealer. Remove the amplifier and accessories from the packaging. Make sure that the content is not damaged.
Do not connect the device to the power supply if it has visible signs of damage.
PACKAGE CONTENT
The package should contain:
- Fezz Titania vacuum tube amplifier
- vacuum tube of type KT88 – 4 pcs.
- vacuum tube of type 12AX7 – 2 pcs.
- power cord user’s manual
- cotton gloves
- optional: remote control, vacuum tube protective cage
If any of the above items are missing in your package, contact your dealer immediately.
VACUUM TUBES INSTALLATION
Place the amplifier on a stable surface. Carefully remove the vacuum tubes from their packaging and install them in the appropriate sockets, as show below, and adhering to the numbering scheme as identified on the packaging.
The pins in the base of each of the vacuum tubes are “coded”, and this has the result that the insertion of the vacuum tube into the socket is possible only in one correct and appropriate orientation. If, whilst inserting the vacuum tube you will sense resistance, and you can not push the tube into the socket, please check the orientation of its pins, rotate the tube to the correct position and try again.
WHERE TO PLACE YOUR AMPLIFIER
Due to the presence of high temperatures during normal operation of the vacuum
tubes, the location that you pick to place your amplifier should ensure ample
ventilation, a free flow of air. Please maintain at least 10 cm clearance
between the housing of the amplifier, together with the vacuum tubes, and
other devices or elements of the interior.
The sound quality may be degraded as a result of vibrations. Therefore we
recommended to place the amplifier on a flat and stable surface.
Never place the amplifier near the source of heat.

The figure above shows the rear panel view of the amplifier, together with a description of the inputs and outputs allowing for connection of the other elements of your audio system.
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.
STEP 1 SPEAKERS CONNECTIONS
Check the impedance of the speaker set. Connect the speaker cable to the appropriate terminals on the rear panel of the amplifier. Depending on the impedance of the speakers, connect it to the terminal marked either 4 Ω or 8 Ω. If your speaker impedance is 6 Ω – connect the speaker wire to the terminal 8 Ω.
NEVER TURN ON THE AMPLIFIER WITHOUT CONNECTED SPEAKERS
Connect the signal source to the amplifier inputs IN1, IN2 or IN3. Select the
source of input signal by rotating the input selector located on the front
panel of the amplifier. In order to achieve the highest sound quality, use
only high-quality RCA cables.
Pay attention to the proper connection and distinction of the right (R) and
the left (L) channels. For the best sound quality, we suggest using the Fezz
FAC 01 interconnect cable dedicated for Fezz Audio vacuum tube amplifiers.
To connect a turntable, you will need to use an external phono MM/MC preamplifier or turnatble with a built-in preamplifier.
STEP 3 POWER CORD CONNECTION
Make sure that the amplifier is switched off. Connect the power cord to the IEC socket on the rear panel of the amplifier.The amplifier is designed to operate at a rated voltage of 230V / 50-60Hz. Connecting the device to a mains network with incorrect parameters can lead to damage that is not covered by manufacturers warranty.
FIRST POWER-UP AND GETTING
Make sure that all of your wiring is connected in accordance with the
information as provided above.
Select the source of signal using the rotary selector switch located on the
front panel. Set the volume control to minimum. Turn on the mains power of the
amplifier – the vacuum tubes shall begin to glow. Make sure that the sound
source is turned on, playing, and then gradually increase the volume level by
turning the potentiometer.
The operation of the amplifier narrows down to adjusting the volume via VOLUME
potentiometer and selecting an audio signal source via rotation of the SOURCE
switch.
BURING-IN PROCESS
Any tube amplifier requires an initial pre-heating (or „burn-in”) period, in
order so that it achieves its full sonic potential. This is due to the
presence of residua polarization of dielectric elements and due to a necessary
stabilization of working parameters of the vacuum tubes. The stabilization of
the electrical parameters of the system occurs in a natural process whilst
playing music through your audio system.
A preliminary degree of pre-heating of the amplifier is reached after about 10
hours of quiet music playback. Full sonic capabilities shall stabilize and
unfold within a time-span ranging from 40 to 60 hours of music reproduction at
a moderate volume levels.
VACUUM TUBES REPLACEMENT
Your amplifier is equipped with automatic bias module. It’s necessary to use vacuum tubes that have previously been preselected and paired up in quads or pairs.
- Disconnect the amplifier from the mains socket, the power supply network.
- Remove the currently installed tubes from their respective sockets. Plug in the new replacement vacuum tubes in these sockets.
POWER TUBES FUSES REPLACEMENT
Every power tube has its own safety fuse (symbol – m100mA). When power tube will fail safety fuse will blow and prevents any further damage of the amplifier. Foulty fuse is singalised by red light. Please replace the power tube fuse with new m100mA if needed. If the fuse will blow again please replace foulty power tube with new one.
OPTIONAL EQUIPMENT
VACUUM TUBES PROTECTIVE CAGE
HT (PRE-IN) INPUT
The additional HT (Pre-in) signal input makes it possible to use this amplifier as a stereo power amplifier. In order to make this possible, it is necessary that you have a separate preamplifier with its own volume control, or a receiver with ‘Pre out’ output.
Never directly connect sources such as a CD player, DVD player, BluRay players, DAC or similar devices to the HT (pre-in) input. The HT input is specifically and exclusively designed for use with preamplifiers with adjustable output volume and with recivers which are equipped with a „pre-out”
