100/70/50 V-line systems
An optional transformer kit (CXL-60T) is available for the MA60/MA60
media
, to
permit the unit to directly drive 100 V, 70 V or 50 V-line loudspeaker systems. The
transformer is rated at 50 W output, and is mounted internally. The outputs are
available on a 4-pin 5 mm-pitch screw-terminal connector which occupies the hole
9
in the rear panel normally covered by a blanking plate.
Fitting the CXL-60T transformer kit
The transformer kit comprises the following items:
•
CXL-60T toroidal transformer, terminated in a PCB-mounted 4-pin connector
•
M6 countersunk-head fixing bolt
•
Safety cover
•
2 x M3 hex pillars
•
2 x M3 x 6 screws
•
Mating 4-pin connector
•
2 x cable ties
Proceed as follows:
1. Disconnect the MA60/MA60
media
from AC mains.
2. Take the top panel off by removing the eight M3 screws (six on the top panel
itself; two through the front panel) securing it.
3. Turn the unit upside down, and remove the plastic blanking plug from the M6
hole in the base of the unit. (The hole is in the centre of the chassis, about
8 mm behind the front panel.) Insert the M6 fixing bolt supplied with the kit
through the hole.
4. Fit the transformer with the fixing screw through its central core. The top of
the transformer has a threaded M6 insert; tighten the screw from underneath
using a hex key.
