Before removing the amplier from the box, please be careful of the following:
1
The Standby/Operation switch located on the rear of the amp is fragile, so care should be taken not
to damage it when lifting the amp from their foam packaging. Similarly, care should be taken not to
damage the rear binding posts.
The pearl anodized coating on the industrial-grade chassis of the amplier is highly susceptible to
ngerprints, so we recommend wearing cloth gloves when handling the amplier. Wipe away
ngerprints using a dry cloth, wiping with the grain of the chassis.
Do not wipe against the grain or use materials which contain silicon, such as the cloths used for
polishing eyeglass lenses.
Verifying that the amplier has not been damaged in shipping:
2
(Before placing the amplier for operation inspection and use in the system, the user may wish to
install the attached feet. Please understand that the feet are for convenience only—in order to
provide clearance for the user’s ngers when the amplier must be lifted—and are not intended to
be “audiophile grade. ” We believe that because isolation devices do inuence the sound to a
greater or lesser extent, they should be chosen according to the user’s taste, which is why we do not
attempt to provide “high-quality” feet that might imply recommendation of a particular tuning
philosophy. Most CF-080LS owners use their own isolation devices between the ampliers and
whatever stands or shelves they are resting upon.)
BEFORE hooking the amplier up to the system via interconnect cables, plug in ONLY the power cord
and then turn POWER switch into the ON position.
Please conrm that white LED on front panel for INPUT 1 is illuminating, showing that the ampliers
are operating properly.
If either the White LED ( INPUT 1) or level indicator is not illuminating, turn o the power to the
amplier, disconnect it from the wall outlet, and notify your dealer.
