3 UNPACKING
The DX-3SP is packed in a heavy duty package easily sufficient to protect the amplifier during transportation,
even in case of fairly rough handling. The weight of the mains transformer does mean, however, that dropping
the amplifier would without doubt result in some damage when the transformer is installed inside.
3.1
Opening the carton
When opening the packing, do not cut the carton. Save the packing material for possible further re-use.
Shipment of your DX-3SP in other than factory packing may result in non-warranty damage.
3.2 Opening the DX-3SP cover
Remove the 4 screws on each side and remove the cover. An inspection of the interior of the amplifier should
reveal no damage or adversely affected components. Should there be any form of problem, notify your
supplier immediately.
3.3 Installing the transformer
Make sure the transformer is wired for the nominal mains voltage in your area. See 7.4.
Two people are needed to install the transformer. The best is to put the DX-3SP on a flat, smooth surface such
as a bench or a table-top, covered by a small carpet of a folded blanket, so that it can be moved by sliding it
on the table. Locate the cover micro-switch and temporarily tape the micro-switch down to avoid damage to
the sense wire during transformer installation
.
Lift the transformer and lower it into the chassis, positioned with the 12-pin connector towards the front of the
amplifier. Put the transformer in at a slight sidewise angle, while taking care that it does not touch the sections
of the wire loom between the control board and the front panel display. Mind also the micro-switch, the front
panel switches and the control board at the back.
