Selector only determines what is heard through the speakers, it will not affect the signal chosen for
recording with the Recording Selector.
The Recording Selector also allows you to copy (dub) from one tape deck to another. To copy from
Tape 1 to Tape 2, select the Tape 1 setting on the Recording Selector. To copy from Tape 2 to Tape 1, select
the Tape 2 setting on the Recording Selector. Remember; the Recording Selector does not determine
what you hear through the speakers To listen to eitherTape 1 orTape 2 you must make the appropriate
selection using the Listening Selector. It should be noted that unlike conventional preamps, actual
signal switching is done on the circuit board near the rearpanel inputs.This arrangement will keep hum,
noise and distortion to a minimum by eliminating the wire necessary for front panel switches The
front panel selector is only making a mechanical change and has no wines going through the control.

THE CARE AND FEEDING OF YOUR GFP-555
Great care has been taken by ADOOM to assure that your preamplifier is as flawless in appearance
as it is electronically. The front panel is heavy gauge, high-grade anodized aluminum, bead-blasted for
durability and beauty. It the front panel should become fingerprinted or smeared, it can be cleaned with
a damp, soft cloth.
The preamplifier is protected by a line fuse on the wpanel. if the power is switched ON and the
small red LED on the front panel does not illuminate aftera few seconds, shut off the preamplifier, unplug
the AC line cord from the power outlet. and check the AC line fuse. If the fuse has opened, replace it ONLY
with a fuse of equal value after carefully checking to determine the cause of the failure This product also
contains internal fuses which are designed to open under certain overload conditions. Should the pre-
amplifier cease to function and the external line fuse is OK, it is likely that an Internal fuse has opened.
You may have this checked by your authorized ADOOM dealer, and thereby avoid the inconvenience or
unnecessary return to the factory.
REPLACEMENT WITH AN INCORRECT FUSE OR ONE OF A HIGHER RATING WILL NOT PROTECT
THE PREAMPLIFIER AND WILL VOID THE WARRANTY.
