Each transformer is also supplied with an M5 hex-head screw, locknut and washer.
To fit convert one channel of a 46-120 to 70/100 V-line operation, proceed as follows:
1. Disconnect the 46-120 from the mains.
2. Remove the top cover (10 screws) and orient the unit with the rear panel towards you.
3. Mount the CXL-46T transformer on the right-hand side of the 46-120 chassis, using one of the holes in the side of the chassis
and the M5 screw, washer and locknut supplied with each transformer. The bolt passes through the centre of the toroid, and
the screw head should be on the outside of the chassis. If fitting fewer than four CXL-46Ts, any of the fixing positions may be
used. Orient the transformers so that the flying leads face the rear of the chassis.
4. For the zone being converted to 70/100 V-line operation, unplug the relevant 4-pin female connector from its
ZONE O/P
socket on the main PCB immediately behind the rear panel
SPEAKER OUTPUTS connector. There are four of these (one
per zone): CON38 (Zone 1), CON39 (Zone 2), CON40 (Zone 3) and CON41 (Zone 4) - see diagram below. Note that
CON38 is orientated at 180° relative to the other three.
