Please read thoroughly the operating instructions for the GTP»4OO before connecting or attempting to operate
this unit. For your own benefit. follow all the instructions in this manual and save it for future reference.
Your ADCOM GTP~400 incorporates some of the most advanced thinking in linear-gain. very-fast semiconduc-
tor design. Its superior perturrnance is the result of a thorough re-evatua‘tion of all factors affecting analog
audio performance in he Digital Age; factors such as headroom, dynamic range, input-output linearity and
a minimum the possibility of transportation damage, should the product ever need to be shipped again. in
the unlikely event damage has occurred, notify your dealer immediately and request the name ot the carrier
so that a written claim to cover shipping damage can be initiated. .
THE RIGHT TO ANY CLAIM AGAINST A PUBLIC CARRIER CAN BE FORFEIT ED IF THE CARRIER IS
NOT NOTIFIED PROMPTLY IN WRITING AND IF THE SHIPPING CARTON AND PACKING MATERIALS
ARE NOT AVAILABLE FOR INSPECTION. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS
BEEN SETTLED. '
INSTALLING THE GTP—4OO
For use in professional installations, the GTPv400 may be mounted in a standard 19-inch rack using the
optional RM-a rack mount adaptors available through ADCOM dealers.
CONNECTING THE GTP-400
The performance of the GTP-400 depends on the quality of the interconnection of both the Tuner/Preamplifier
and its associated equipment All the output signal connections should be made only with high-quality, low-loss
audio cables. LEFT and RIGHT inputs and outputs are dearly labeled.
Whenever connections to or from the GTP~400 are being made, be certain all associated components are
E and AMI. It does not matter which wire goes to which of the two screws. By swinging the ferrite loop out
and away from the rear panel of the GTP-400, you can “orient" the antenna for best reception of desired
stations with minimum noise. In some very noisy locations. it may be necessary for best reception to remove
the antenna from its bracket and position it away inom the chassis oi the GTP-400. The length at the wires
