the master volume control.
Power outline voltage complies with power input voltage (IEC voltage).
Loudspeaker Connection
Note: Use only 100V or 70V (Selectable) Line Loudspeakers
Low Impedance (8
Ω
)
This output allows connection of standard low impedance loudspeakers, the minimum load
impedance must be 8
Ω
, when to or more loudspeakers are use ensure that they are wired in
such a way that the load impedance is between 16
Ω
or between (4
Ω
).
Connecting a Mixer Amplifier to a Power Amplifier
These amplifier can be connected using phono to phono leads from the mixer amplifier PRE out
the power amplifier input RCA socket. Further power amplifier can be connected by connecting
from the output of first power amplifier to the input of the second. Up to three power amplifier
can be connected in this way.
Input must be from power amp in (Rear Panel) (Mic1 XLR Jack)
