Operation Manual

OUTPUTS
LOW IMPEDANCE:
Use the COM-8 Ohm output in case the distance to the loudspeakers is shorter than
50 t0 75 metres.
When using low impedance loudspeakers, the total power of the loudspeakers
should be equal or larger than the amplifier output. Otherwise one or more
loudspeakers will be damaged when
the output is at its maximum. Make
sure the total impedance remains
in between 4 and 16 ohm:
When connected in series, the
impedances of each of the speakers
can be added.
When (equal) loudspeakers are
connected in parallel, the impedance
of a single loudspeaker must be
devided by the number of speakers.
Eventually, use a combination of series
and parallel connection to obtain the
required impedance.
LINE OUTPUT:
Use the COM-25V, COM-70V or COM-100 V output terminals for loudspeaker-distan-
ces of more than 50 to 75 metres. Use only speakers with a line transformer.
In case of connection to the 100 volt output,
the power of all loudspeaker (-transformers)
connected should be equal or less than the
effective RMS output power of the amplifier
(PAX-30 = 30 Watt / PAX-120 = 120Watt).
Should more loudspeakers be connected than
the amplifier can supply, the amplifier will burn
out no matter what the settings of the volume
controls are.
All loudspeakers should be connected in parallel; with the 100 volts system, series
connection is not allowed.
