2.2 Foot mounting
CDA-4D can also be table mounted and is supplied
with feet and feet screws, see Diagram 3.
Ensure that, once positioned, the amplifier is well
ventilated and that the ventilation apertures are not
obstructed. If the system is taken out of use for a
long period, disconnect the amplifier from the mains
power supply.
To prevent damage, maintain adequate
ventilation space to the sides of the amplifier.
CDA-4D can be stacked vertically but
be sure not to place the amplifier next to other
components, or against the side of a cabinet.
Doing so will block ventilation openings.
