ADCOM GFP-715 Owner’s Manual |
Introduction
Congratulations on your decision to
purchase the GFP-715 stereo preamplifier.
Two channel audio is better than ever!
The new DVD Audio and SACD formats
can support a wider frequency spectrum
(100kHz) and greater dynamic range
(144dB) than conventional CD. The GPF-
715 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 processor loop, a tape loop and
a phono stage, this new ADCOM preamp
hasn’t forgotten about your legacy
components. Audition the GFP-715 paired
with an ADCOM power amp and 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.
Key Features
• Class A line level preamp
• high resolution audio bandwidth
• 4 audio inputs
• 1 phono input stage
• tape output w/ monitor function
• external processor loop
• bass, treble, and balance adjust
• front panel headphone input
• remote control
Unpacking the GFP-715
Before your new ADCOM preamplifier
left our factory, it was carefully
inspected for physical imperfections
and
tested
for
all
electrical
parameters as a routine part of
ADCOM’s systematic quality control.
This, along with full operational and
mechanical testing, should ensure a
product flawless in both appearance
and performance. After you have
unpacked the GTP-715, inspect it for
physical damage. Save the shipping
carton and all packing material as they
are intended to reduce the possibility
of transportation damage should the
preamplifier ever need to be shipped
again. In the unlikely event damage
has occurred, notify your dealer
immediately 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.
Placing the GFP-715
Although the GFP-715 does not
generate much heat, it is good practice
to ensure the amplifier’s long-term,
trouble-free operation to provide
adequate ventilation for the unit.
Therefore, the GFP-715 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-715. If you are placing a
heat producing component (such as an
amplifier) on top of or below the GFP-
715, 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 placing
components above or under the GFP-715
may induce hum, caused by the proximity
of their power transformer to the phono
cables or input jacks. If this should occur,
moving the components will usually help
reduce the hum.
If you observe these recommendations,
the GFP-715 will perform reliably
in any reasonable environment. You
should also pay attention to such
normal considerations as protection
from excessive dust and moisture.
Occasional vacuuming of accumulated
dust on the chassis panels and around
the ventilating slots should be all that
is required.
The optimal perfomance of your new
GFP-715 will ultimately depend on
the care with which you make the
connections between the amplifier,
preamplifier and loudspeakers. All
input and output signal connections
should be made only with high quality,
low-loss, low capacitance cables. For
recommendations of the type and
quality of interconnections that are
best for your applications, consult with
your ADCOM retailer.
Safety Information
There are no user serviceable parts
inside. Refer all servicing to qualified
service personnel.
The unit must be connected to a power
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
defeat grounding and/or polarization
provisions. The cable should be
connected to a 3-pin polarized wall
outlet, matching the wide blade of the
plug to the wide slot of the receptacle.
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 qualified service
agency if:
• the power supply cord or plug has
been damaged;
• objects have fallen or liquid has
been spilled into the unit;
• the unit has been exposed to rain;
• the unit shows signs of improper
operation; or
• the unit has been dropped or
damaged in any way.
