(here after we will call it " ) .
·
·
·
·
·
·
·
The AMC model XCDi was designed to meet professional quality performance
standard and to provide superior value.
Selected grade components are utilized throughout the circuit design with special
emphasis on components within the audio path to assure stable, consistent
performance.
Premium transport and servo drive system assures constant data retrieval and
unsurpassed tracking performance,
Unique linear active LPF (Low Pass Filter) prevents interference from ultrasonic
noise commonly found in other CD playback systems.
Advanced power supply design incorporates separate windings for the digital,
analog and servo circuits to prevent interference and preserve sonic performance.
EIA calibrated audio outputs ensure proper match with preamplifiers and receivers.
Full-function infrared (IR) System Remote Control (for system including XCDi
Compact Disc Player and X7i Stereo Receiver) with direct track access.

(APPLIES TO TUNERAND RECEIVERS ONLY)
An outdoor antenna should be located away from power lines.
(APPLIES TO TUNERAND RECEIVERS ONLY)
If an outside antenna is connected to the receiver, 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/NFPANo.
70-1984, 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 requirements for the grounding
electrode. See Figure.
a) Use No. 10 AWG (5.3 mm ) copper, No. 8 AWG (8.4 mm )
aluminum, No. 17 AWG (1.0 mm ) copper-clad steel or
bronze wire, or larger, as a ground wire.
b) Secure antenna lead-in and ground wires to house with
stand-off insulators spaced from 4-6 feet (1.22-1.83 m)
apart.
c) Mount antenna discharge unit as close as possible to where
lead-in enters house.
d) Use jumper wire not smaller than No.6 AWG (13.3 mm )
copper, or the equivalent, when a separate antenna-
grounding electrode is used. See NEC Section 810-21(j).
