Power Sharing (Model 46-120MK2 only)
Model 46-120MK2 incorporates the principle of Power
Sharing when the outputs of Zones 1 and 3 and/or Zones 2
and 4 are congured for Hi-Z mode (i.e., for 70/100 V-line
operation). The maximum power available for ZONE 1 and
ZONE 3 combined is 240 W; the maximum power available
for ZONE 2 and ZONE 4 combined is also 240 W. Each zone
output is capable of delivering 240 W, but this gure can only
be realised if the other zone output in the odd- or even- pair
is unused.
Power Sharing is congured by adjusting the power tapping
(wattage setting) on all 70 V-line or 100 V-line speakers. In
each zone, the tappings should be set to give the required
total wattage (e.g., Zone 1: 40 W total, Zone 3: 200 W total).
The power sharing between the zones in the same odd- or
even-numbered pair can be any ratio, provided the total
wattage rating for both zones does not exceed 240 W.
The great advantage of power sharing is that it allows
installers to use one zone output to drive speakers where
only low power is needed, and the other for areas where
more is needed.
Parallel power stage operation
46 Series mixer-ampliers may be congured so that one
zone signal (mix of music and mics) is routed to two output
stages “in parallel”. This gives the installer the additional
exibility of obtaining more power to drive the loudspeakers
in a single zone. This may be particularly useful with Model
46-240, which lacks the Power Sharing capability of the 46-
120MK2.
Note that parallel operation will reduce the total number of
zones that can be catered for to either three or two.
Parallel power stage operation is congured by moving
internal jumpers J25 and/or J26. By default, the pre-amplier
stages of Zones 1 to 4 are routed to the power output stages
of Zones 1 to 4 respectively. Moving J25 from its default
setting of ‘Z3’ to ‘Z1’ will route the output of Zone 1’s pre-
amplier stage to the input of Zone 3’s output stage as well
as to Zone 1’s output stage. Similarly, moving J26 from its
default setting of ‘Z4’ to ‘Z2’ will route the output of Zone
2’s pre-amplier stage to the input of Zone 4’s output stage
as well as to Zone 2’s output stage.
Parallel power stage operation is available on both the 46-
120MK2 and 46-240, and is independent of the 46-120MK2’s
Power Sharing capability described in the preceding section
