Adcom GFP-815 - Manual (Page 4)

Introduction
Congratulations on your decision to
purchase the GFP-815 stereo preamp-
lifier. Two channel audio is better
than ever! The new DVD Audio and
SACD formats can support a wider fre-
quency spectrum (100kHz) and great-
er dynamic range (144dB) than con-
ventional CD. The GPF-815 is designed
to capture all the fidelity that high
resolution audio has to offer, with
precision broadband components and
an ultra low noise floor. Equipped
with a phono stage, this new ADCOM
preamp hasn’t forgotten about your
legacy components. Audition the GFP-
815 paired with an ADCOM power amp
and CD / DVD player and rediscover
the magic of two channel. To realize
the full potential of your new stereo
preamplifier, and before making any
connections to it, please read these
operating and installation instructions
thoroughly.
Placing the GFP-815
Unpacking the GFP-815
In the unlikely event damage has oc-
curred, notify your dealer immediate-
ly and request the name of the carrier
so a written claim to cover shipping
damages can be initiated. The right to
a claim against a public carrier can be
forfeited if the carrier is not notified
promptly in writing and if the shipping
carton and packing materials are not
available for inspection by the carrier.
Save all packing materials until the
claim has been settled.
Although the GFP-815 does not gen-
erate much heat, it is good practice to
ensure the amplifier’s long-term,
trouble-free operation to provide ad-
equate ventilation for the unit. There-
fore, the GFP-815 should be kept
away from external sources of heat
such as radiators and hot-air ducts.
We recommend that you exercise care
when placing components on top of
the GFP-815. If you are placing a heat
producing component (such as an am-
plifier) on top of or below the GFP-
815, it is recommended that you allow
at least 3 inches vertical spacing for
proper airflow.
If your system includes the use of the
phono input, you may find that pla-
cing components above or under the
GFP-815 may induce hum, caused by
the proximity of their power trans-
former to the phono cables or input
jacks. If this should occur, moving the
components will usually help reduce
the hum.
The optimal performance of your new
GFP-815 will ultimately depend on the
care with which you make the connec-
tions between the amplifier, pream-
plifier and loudspeakers. All input and
output signal connections should be
made only with high quality, low-loss,
low capacitance cables. For recom-
mendations of the type and quality of
interconnections that are best for
your applications, consult with your
ADCOM retailer.
There are no user serviceable parts
inside. Refer all servicing to qualified
service personnel.
Safety Information
The unit must be connected to a pow-
er supply only of the type and voltage
specified on the rear panel. Connect
the component to the power outlet
only with the supplied power supply
cable or an exact equivalent. Do not
modify the supplied cable. Do not de-
feat grounding and/or polarization
provisions. The cable should be con-
nected to a 3-pin polarized wall out-
let, matching the wide blade of the
plug to the wide slot of the recepta-
cle. Do not use extension cords. Do
not route the power cord where it will
be crushed, pinched, bent, exposed to
heat, or damaged in any way. Pay
particular attention to the power cord
at the plug and where it exits the
back of the unit. The power cord
should be unplugged from the wall
outlet if the unit is to be left unused
for a long period of time. Immediately
stop using the component and have it
inspected and/or serviced by a quali-
fied service agency if:
If you observe these recommendations
the GFP-815 will perform reliably in
any reasonable environment.
You should also pay attention to such
normal considerations as protection
from excessive dust and moisture.
Dust on the surface of the cabinet can
be easily and safely removed with a
duster such as made by Swiffer™. Fin-
ger prints can be removed with a soft
cloth dampened with a mild non-
ammonia cleaner.

Key Features
Before your new ADCOM preamplifier
left our factory, it was carefully in-
spected for physical imperfections
and tested for all electrical parame-
ters as a routine part of ADCOM’s sys-
tematic quality control. This, along
with full operational and mechanical
testing, should ensure a product flaw-
less in both appearance and perfor-
mance. After you have unpacked the
GTP-815, inspect it for physical dam-
age. Save the shipping carton and all
packing material as they are intended
to reduce the possibility of transpor-
tation damage should the preamplifier
ever need to be shipped again.
