- Never turn on the amplifeir without installed tubes and without hooked-up spekers.

- Never place the Fezz Audio Titania power amplier near heat sources, such as radiators, heaters or direct sunlight. Ensure

adequate ventilation and airow

- We also warn against exposure of the amplier to conditions such as very low temperatures and/or high humidity.

- During normal operation, the vacuum tubes radiate signicant amounts of heat - there is a risk of burns.

- The amplier should be plugged directly into a wall socket. If you must use an extension cord, please make sure that it

has load parameters sucient to ensure proper handling of current delivery to the device.

- When cleaning, always disconnect the Titania amplier from the power source. Use a dry, soft cloth. Do not use water or

cleaning agents.

- If your amplier 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 amplier.

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 specication.

- Do not make repairs on your own, or adjustments beyond those as described in this manual. Execution of any

unauthorized repairs or modications of the device result in a loss of warranty.

Nowadays HiFi audio world becomes increasingly digital, Fezz does not forget about analog lovers.

New version of Titania powem amplier is based on the Titania tube amplier. In standard equipped with anti-vibration feet,

adapted to the weight of the device. Backlight logo. Easily accessible fuses protecting the the deivce in case of a power tube

failure. Power amp combines all its advantages. Openness, full bodied sound, yet with a remarkably neutral tone. Two modes:

stereo and mono makes it very powerfull and versatile.

PACKAGE CONTENT

Place the amplier 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 identied on the packaging.

Due to the presence of high temperatures during normal operation of the vacuum tubes, the location that you pick to place

your amplier should ensure ample ventilation, a free ow of air. Please maintain at least 10 cm clearance between the

housing of the amplier, 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 amplier on a

at and stable surface.

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 amplier. 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 amplier channel. Be sure your

power amplier is turned o. 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.

Connect the preamplier output to the signal source in the Titania power amplier 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 ampliers.

Any tube amplier/power amplier 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 amplier 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.

Your power amplier 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.

1) Disconnect the amplier from the mains socket, the power supply network.

2) Remove the currently installed tubes from their respective sockets. Plug in the new replacement vacuum tubes in these

sockets.

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 amplier – 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 preamplier.

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 amplier. Please replace foulty power tube with new one. Please replace the power tube fuse with

new m100mA if needed.

Make sure that the power amplier is switched o. Connect the power cord to the IEC socket on the rear panel of the power

amplier.

The power amplier 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.

If you have veried the aforementioned situations, and your problem still persists, please contact your local Fezz Audio dealer.

If your amplier does not work as it is supposed to, it is fairly easy to diagnose and remedy some of the common malfunctions,

by following procedures as outlined in this following.

THE PROBLEM PROBABLE REASON SOLUTION

After turning the power

switch to the ON position, the

amplier does not switch on.

A blown fuse Please exchange to faulty fuse to a new one (3,15A T),

within the fuse holder as depicted with index 4 on

page 8 of this user’s manual.

An improper connection of the

mains cable

Please check if the plugs of the mains cable are properly

inserted into the electrical mains socket and to the

socket as depicted with index 5 on page 8 of this user’s

manual.

The sound produced by the

amplier is distorted. A hum

or pops have appeared and

are coming from one of the

channels.

An improper placement of the

vacuum tubes in the sockets

Switch o the amplier. Wait until the vacuum tubes

cool down. Check for proper placement of vacuum

tubes in their sockets. If necessary – correct their

orientation.

One of the driver tubes

(12AX7) has lost its nominal

working parameters

Switch o the amplier. Wait until the vacuum tubes

cool down. Exchange the positions of the driver

tubes between channels. Turn on the amplier. If the

disturbing sounds have moved to the other channel,

inform Your local Fezz Audio dealer about tube which

need to be replaced.

One of the Power tubes (KT88)

has lost its nominal working

parameters

Switch o the amplier. Wait until the vacuum tubes

cool down. Exchange the positions of the power

tubes between channels. Turn on the amplier. If the

disturbing sounds have moved to the other channel,

inform Your local Fezz Audio dealer about tube which

need to be replaced.

One of the power tube fails. It

can cause fuse failture.

Please exchange a faulty tube and then exchange

power tube fuse to a new one m100mA, within the

fuse holder as described with index 9 at page 4 of this

user’s manual.
