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 power 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.

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 PA vacuum tube amplifier
- vacuum tube of type KT88 – 4 pcs.
- vacuum tube of type 12AX7 – 2 pcs.
- power cord
- user’s manual
- cotton gloves

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 POWER 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 power 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 power 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 power 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 SPEAKERS CONNECTIONS
Stereo mode:
Check the impedance of the speakers set that you own. Connect the speaker
cable to the appropriate terminals on the rear panel of the amplifier.
Depending on the impedance of the speakers that you own, 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.
Mono mode:
Bridge mono mode combines two amp channels into one mono,it gives much more
powerful amplifier channel. Be sure your power amplifier is turned off. Set
the MONO MODE switch to the “MONO” position and connect the speaker terminal
using terminal jumper to the terminals marked ‘L +’ 4 Ω and ‘R+’ 4 Ω and
second terminal jumper ‘L +’ 8 Ω and ‘R+’ 8 Ω ensuring that the ‘L+’ is
connected to the ‘+’ terminal on your loudspeaker and the ‘R+’ is connected to
the loudspeaker’s ‘-’ terminal. See picture above.
ALWAYS DISCONNECT THE TERMINAL JUMPERS WHEN THE POWER AMPLIFIER IS SET IN
STEREO
STEP 2 AUDIO SIGNAL SOURCES CONNECTIONS
Connect the preamplifier output to the signal source in the Titania power
amplifier input (IN)
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 power amplifier is switched off. Connect the power cord to
the IEC socket on the rear panel of the power amplifier.
The power 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 on page 9 of this manual. Turn on the mains
power of the Titania power 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 in your preamplifier.
BURING-IN PROCESS
Any tube amplifier/power 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.
The 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 power amplifier is equipped with automatic bias module. It’s necessary to
use vacuum tubes that have previously been
pre-selected 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. Please replace foulty power tube with new one. Please replace the power tube fuse with new m100mA if needed.
