fuse box are placed at the rear panel.
- Never operate the amplier through an ungrounded
outlet!
- The amplier 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 amplier outputs are speaker ports marked
0 Ω and 4 Ω as well as 0 Ω and 8 Ω.
- Never operate the amplier without a sufcient load!
Do not power up the amplier until correct loads (4 Ω
or 8 Ω, marked on the amplier) are connected to the
output ports!
