- Due to the vacuum tube construction of the amplier,
the it may heat up during use. Thus, choose a loca-
tion for installation where the appliance can be well
ventilated!
- Make sure that cables connecting the amplier to the
speakers as well as cables connected to the ports of
the amplier can be effortlessly connected.!
- Appliance can only operate with 50 Hz frequency and
230V AC voltage! The standard AC socket and the
fuse box are placed at the rear panel.
- Never operate the amplier through an ungrounded
outlet!
- The amplier can be connected to an audio system
through RCA ports at the rear panel. Input sensitivity
is 665 mV.
- According to the nominal impedance of the speakers
used, the amplier outputs are speaker ports marked
0 Ω and 4 Ω as well as 0 Ω and 8 Ω.
- Never operate the amplier without a sufcient load!
Do not power up the amplier until correct loads (4 Ω
or 8 Ω, marked on the amplier) are connected to the
output ports!
