Unpacking
Carefully open the shipping carton and inspect the DDP. Every Alcons
product is thoroughly tested and inspected before leaving the factory and
should arrive in perfect condition. If you find any damage, notify the shipping
company immediately. Only you, the consignee, may initiate a claim for
shipping damage. Be sure to save all packing materials for the carrier’s
inspection.
Please save the packing material. If you ever need to ship the DDP back to
your dealer or the factory, you should only use the original packing.
Installation in the ALC amplifiers
To install the DDP module in your Alcons ALC amplifier, first switch off the
amplifier and unscrew the cover on the front panel. Set the both the Parallel
mode and the Bridge mode switch to the left hand OFF position. If the ALC
is an –ST version turn both input gain controls completely clockwise to the
32 dB gain position. Place the DDP module in the space behind the cover,
making sure the connectors have
locked. Then secure the module
with the two supplied M3x6 bolts.
The DDP controls the signal
routing for parallel/active
mode and bridge mode
itself. This means that the
parallel mode and bridge
mode DIP-switches of the
ALC amplifiers should
always be in the left
hand OFF position.
