Loudspeaker
Connect loudspeakers to amplifier on screw terminals.The loudspeakers must be connected in a series or
parallel circuit so that the charge impedance of the loudspeakers is the same as the charge impedance of
the amplifiers, and that the power supplied by the amplifier does not exceed that withstood by the loudsp-
eakers.Loudspeaker’s resistance during operation must not exceed 8 ohm or fall below 4 ohm.
Stereo Mode
The amplifier can operate two speakers or two speaker groups. It is able to deliver 2 x 300 watts for 4
Ω
speakers
and 2 x 200 watts for 8
Ω speakers. Connect speaker with red (positive) and black (negative)
terminals in this mode.
Bridged Mode
Output power of amplifier can be doubled to switch over to bridge mode and operate one speaker or one
speaker group. Connect speaker with two red screw contacts in bridged mode The final impedance must
be working at 8Ω stable use.
Alternatively, it is possible to operate one 100V PA speaker or speaker group in 200 watts. In this case, use
the two positive terminals (red) for the connection.
