OUTDOOR ANTENNA GROUNDING
If an outside antenna is connected
to your tuner or tuner / preamplifier, be sure the antenna system is
grounded so as to provide some protection against voltage surges and
built-up static charges. Section 810 of the National Electrical Code,
ANSI/NF A No. 701984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding conductors, location
of antenna discharge unit, connection to grounding electrodes, and re-
quirements for the grounding electrode.
Use No.10 AWG (5.3 mm

Introduction
Congratulations on your decision to
purchase the GF -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 G F-
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 GF -
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.
Placin the GFP-815
Unpackin 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 GF -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 GF -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 GF -815. If you are placing a heat
producing component (such as an am-
plifier) on top of or below the GF -
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
GF -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
GF -
815 will ultimately depend on the
care with which you make the connec-
tions between the amplifier, pream-
plifier and loudspeakers. All in
put 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
n
ot route the power cord where it will
be crushed, pinched, bent, exposed to
heat, or damaged in any way. ay
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 GF -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 ADCO 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
GT -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.

Troubleshootin
Servicin
Cable-TV incoming signal line (round, 75Ω) at the wall,
or the first component the cable is connected to (i.e. the
cable box, or VCR). If the hum is no longer present, you
must insert a “75Ω ground loop isolator” before recon-
necting the line. You should check with your ADCOM deal-
er to obtain one. If the “75Ω ground loop isolator” works
only partially or not at all, then please read note 2 to
complete the troubleshooting procedure.
Note 2: Make sure that the power amplifier is at least 6”
from processor or other equipment using microprocessors.
Usually putting another component between them is suf-
ficient to minimize the hum. If this does not reduce the
hum, turn the system off and disconnect all Inputs from
the amplifier. If the hum still persists, then your dealer or
service center must examine the unit/system. If the hum
disappears, try another set of RCA cables. Connect one
RCA cable at a time to see if one specific cable is respon-
sible. If any or all cables cause the hum to appear, then
the unit should be evaluated for proper operation by your
dealer or authorized service center.
lease see our website
for a list of authorized service centers in your area.
Hum can be caused by adding new components to your
system, but that does not imply there is anything electri-
cally wrong with any new component. With the advent of
audio/video and home theater systems, the problem has
become commonplace. Generally, the cause is the Cable-
TV incoming signal line. This new incoming line may add
an additional ground at a different potential to the AC
line ground of your other equipment (refer to note I and
2, to troubleshoot a hum problem).
ADCOM has a technical service department to answer
questions pertinent to the installation and operation of
your unit. In the event of difficulty, please contact us for
advice. If your problem cannot be resolved through our
combined efforts, we may refer you to an authorized re-
pair agency, or authorize return of the unit to our facto
ry.

ground loop problems which cause “hum.” To determine if
your
cable system is the contributing factor, disconnect the
Use the troubleshooting notes above to solve common sit-
uations that don’t require professional attention. If the
steps stated in possible solution do not resolve your prob-
lem, then please contact your ADCOM dealer or call the
ADCOM customer service department. Any problems not
covered here should be brought to the attention of your
ADCOM dealer or ADCOM customer service department.
A speci l note on “hum:” When there is a low-volume
“hum” audible throughout your speakers, even with the
main volume turned all the way down, you have a com
mon
phenomenon known as a “ground loop.” A ground loop is
basically a difference in ground voltages between two or
more components which are connected electrically and
which creates multiple current paths where there must
only be one. This difference in potentials creates a 60Hz
low-level sound (approximately a low A), that seems to be
a “hum.”
