SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics
or by special notes on the parts list. Use only replacement parts that have critical characteristics
recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are
acceptably insulated from the supply circuit before returning the unit to the customer.
Use the following checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position
and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.)
to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the
unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE
LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE
ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper
wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure
the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic
cabinet part on the unit. When testing 3 wire products, the resistance measured to the product
enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed
input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and
infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard,
and the unit must be repaired and rechecked before it is returned to the customer.

PRODUCT DESCRIPTION
The 3•2•1 Series II Home Entertainment System is the replacement for the 3•2•1 and 3•2•1GS
Series I Home Entertainment Systems. It uses the same system concept of a console with a
dedicated bass module with TrueSpace
arrays.
The console will play video DVDs, DVD-R and DVD+R discs, audio CDs, Video CDs, CD-R and
CD-RWs, and MP3 CDs. MP3 disc tracks must be burned in a single closed session. The MP3
disc format must be ISO9660 and each file must have an “.mp3” extension and have no other
periods in the filename.
The bass module electronics house some signal processing, power supplies and amplification
for the console. The console and bass module are not compatible with the 3•2•1 Series I console and bass module. They cannot be used to replace the other Series components. The
speaker arrays are the same as currently used on the 3•2•1 and 3•2•1GS systems. The system
includes an enhanced universal type IR remote control similar to that used on the 3•2•1GS
Series I system. The remote is non-repairable.
The 3•2•1 Series II uses standard 3•2•1 arrays with a cloth grille. The arrays are graphite in
color. The 3•2•1GS Series II systems use the GemstoneTM arrays in both graphite and silver.
The array cable color matches the array color. The console for both 321 and 321GS systems is
graphite with a silver front bezel. The bass module is graphite, as is the IR remote control.

GLOSSARY OF TERMS
Aspect Ratio - The shape of the rectangular picture in a TV set. It is the width of the picture relative
to the height. Our standard TV picture, is 4 units wide by 3 units high, or 4:3 in aspect ratio. There
are currently two standard TV aspect ratios in the U.S., 4:3 and 16:9.
Chapter - In DVD-Video, a division of a title. Technically called part of a title (PTT).
Component Video - A video signal split into three parts, luminance and two color signals (marked
as YPbPr). It provides the highest resolution video, but cannot be processed by all television sets.
Composite Video - A single video signal that contains luminance, color and synchronization infor-
mation. NTSC and PAL are examples of composite video systems.
®
Dolby Digital
Dolby Digital is a perceptual coding system for audio, developed by Dolby Laboratories and is
accepted as an international standard. Dolby Digital is the most common means of encoding audio
for DVD-Video and is the mandatory audio compression system for 525/60 (NTSC) discs.
DTS - A type of multi-channel surround sound format used on some CDs and DVDs.
DVD - An acronym that is most commonly known to mean Digital Video Disc or Digital Versatile
Disc. The audio/video/data storage system based on 12 and 8 cm optical discs.
- Also known as AC-3, a type of multi-channel surround sound format used on discs.
DVD Video - A standard for storing and reproducing audio and video on DVD-ROM discs, based on
MPEG video, Dolby Digital and MPEG audio, and other proprietary data formats.
Letterbox - The projected aspect ratio of feature films is often 16:9 rather than the 4:3 aspect ratio
of most TVs. Therefore, it is becoming common practice to transfer films to video with black borders at the top and bottom of the picture. The film becomes a “letterbox” within the video.
MPEG - A type of data compression used for audio or video storage on disc.
MP3 - MPEG Layer 3 audio. This is a compressed audio format that allows you to record many
hours of music on a single CD.
NTSC - An acronym for National Television System Committe; the organization that developed both
the American Black & White and Color television systems.
PAL - An acronym for Phase Alternate Line. This is one of several composite video systems.
The PAL format is used extensively in Western Europe.
PCM - An uncompressed, digitally coded representation of an analog signal. This is the form of the
digital audio signal used for both CD and laserdisc. It is a serial data stream that is coded for transmission or recording. PCM is also used for many other types of serial data communications.
S-Video - A video interface standard that carries separate luminance and chrominance signals,
usually on a four-pin mini-DIN connector. Also called Y/C. The quality of S-video is significantly
better than composite video since it does not require a comb filter to separate the signals. Most
high-end televisions have S-video inputs.
Title - Numbered elements of the DVD contents, which may include more than one movie alone.
Track - Individual selections recorded on an audio tape or disc.
