| ADCOM GTP-880 Owners Manual 2
Dear fellow ADCOM product owner,
Welcome to the ADCOM family! For more than twenty years, ADCOM products have delivered
excellent performance and value for customers around the world. Our products are designed by
our experienced and demanding engineering team, built to the highest standards in our factory,
and sold and serviced through dealers, custom installers, and other retailers whose primary goal
is your complete satisfaction.
We know you are anxious to hear your new preamplifier in action, but please take a few minutes
to read this owners manual before connecting the preamplifier to your system. It is particularly
important that you connect your preamplifier to your amplifier while the amplifier and pream-
plifier are unplugged and your other equipment is turned off. This will protect your equipment
from potential short circuits that may occur during installion. In addition, it is important that you
allow for adequate ventilation around your preamplifier and other equipment, since excessive
heat buildup can shorten the life of any electronic product, including the preamplifier. Once you
have correctly connected your new preamplifier to your other components, you should be able
to enjoy many trouble-free years of performance.
We conduct a thorough quality and performance test on each and every preamplifier we build
in our factory prior to shipment. In the rare case of a defect that may occur after shipment, we
stand behind our preamplifiers with a five-year parts and labor warranty. To register for this war-
ranty, please complete and mail the enclosed warranty card back to ADCOM. Also, please keep
a copy of your sales receipt with the owners manual so you may provide proof of eligibility for
the warranty should the need arise.
We know you will be very happy with the sound and performance of your new preamplifier. We
hope you will also consider other ADCOM products, such as our line of multichannel amplifiers and
DVD players. In addition, we design and manufacture complementary products such as surge sup-
pressors and speaker selectors. Please visit our web site at www.adcom.com to learn more about
our complete line of stereo, home theater, and distributed audio/video products.
On behalf of all of us at ADCOM, I want to thank you for selecting our product for your home or
business entertainment system.
Sincerely,
Douglas Klein
President
