Follow the instructions below to connect Your sound system correctly.
STEP 1 / HOOK-UP OF THE SPEAKER
Mira Ceti 300B power amplifier works only in MONO mode. You will need two devices to
make it work in STEREO.
Check the impedance of the speaker 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 speake
r wire to the terminal 8 Ω.
STEP 2 / HOOK-UP OF THE SIGNAL SOURCE
Connect the line preamplifier or variable output to the input source in the Mira Ceti 300B
power amplifier (1)
In order to achieve the highest sound quality, use only high-quality RCA cables. For the best
sound quality, we suggest using the Fezz FAC 01 interconnect cable dedicated for Fezz Audio
vacuum tube amplifiers.
STEP 3 / HOOK-UP OF THE POWER SUPPLY CORD
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 / 50Hz. 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 STARTED______________________
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 Mira Ceti 300B mono 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.
”BURNING
-
IN” THE POWER AMPLIFIER
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.
