Read this section before setting up or operating your new music system
The Techwood DD81 music system is a “state-of-the-art” digital home theater music system. It is equipped
with built-in, Dolby Digital Surround Sound, and is ready for the addition of digital audio/video components
such as DVD, DSS (digital satellite) and HDTV (high definition TV). This section describes some of the
features and Important things you need to know before proceeding with set-up or operation.
The DD81 is equipped with three built-in music sources that can be enjoyed by simply pressing one of the
corresponding function buttons on the front panel or remote control after initial set-up has been completed.
Tuner Plays AM and FM Stereo radio broadcasts
CD Plays music CD’s
Tape Plays and records cassette tapes
You can also connect optional audio/video components to the DD81 and create a true “Home Theater”
experience in your home. This allows the audio sound from the video components to play through the
DD81 music system. You can connect up to three of the following video components:
TV/AUX Television (regular or HDTV), Cable or Satellite Boxes
DVD Digital video disc player
VCR Video cassette recorder/player
To enjoy “Home Theater” surround sound, the Techwood DD81 is equipped with three different types of
Dolby Surround Sound plus, two simulated surround modes. The type of surround sound used to create
your “Home Theater” experience will depend on the video component being played, the type of audio
connection (analog or digital) made to the rear of the DD81 jack panel and the source material being
played. To enjoy true Dolby Surround Sound, the source material must be recorded or broadcast in either
Dolby Pro Logic or Dolby Digital Surround Sound. Source material recorded or
broadcast in stereo, such as radio broadcasts, CD’s, cassette tapes or TV programs can be played using
the Hall or Theater Simulated surround sound modes.
Surround Sound Modes
1) Hall (simulated)
2) Theater (simulated)
3) Dolby 3 Stereo
4) Dolby Pro Logic
5) Dolby Digital (Digital connection and Dolby Digital source required)
The first four types of surround sound will operate when using an analog, stereo audio signal from the tuner,
CD, cassette, TV, VCR, cable or satellite box.
The fifth type, Dolby Digital, will
only
operate when a digital component such as a DVD player, Digital Cable
Box, Digital Satellite (DSS) or HDTV is connected to one of the three digital audio inputs on the rear of the
DD81
and
when a program or disc encoded in Dolby Digital Surround Sound is played.
IMPORTANT: Dolby Digital Surround Sound will not operate with an analog audio signal from the
tuner, CD, cassette, standard TV, VCR or cable box.
Since the DD81 is ready for the addition of digital audio/video components such as a DVD player, High
Definition TV (HDTV) or Digital Cable or Satellite Box, there are digital audio input jacks on the rear of
the unit. Digital audio inputs are included for the
AUX/TV
and
DVD
functions. This allows you to connect
up to two digital audio/video components – one to the AUX/TV function and another to the DVD function.
