WARNING: Make sure that the device is not plugged into the mains before making any connections. It is also
recommended to turn off or disconnect all other devices associated while making connections to the product.
Never operate the amplifier without having first connect the loudspeakers. The operation of a tube amplifier is different
from transistor amplifier; without speakers connected, energy is dissipated through the transformers of the amplifier
which will damage the product and reduce it’s useful life.
Check the impedance of your speakers. When using a pair of speakers, you can use speakers with an impedance of
between 4, 8 and 16 ohms. BE SURE TO USE THE MATCHING TERMINALS.

Speaker connection
1- Unscrew the terminal by hand.
2- Insert the loudspeaker cable (refer to the diagram below).
3- Screw the terminal.
4- Repeat the same operation for the other 3 terminals.
Please notice the polarity of the cable and do not mix up the positive and the negative ends.
Connect the speaker cables with the amplifier after they have been connected to with the speakers.
Make sure that no wires can short the speaker outputs. Make sure that the speaker terminals are tight enough to
ensure a good electrical connection. If the terminal screws are not tight enough, the sound quality may be affected.
Use only dedicated wire to connect the speakers. A section of 1.5 mm² or more is recommended if the cable length is
greater than 3m.
