INTRODUCTION
Yamaha developed the YHT-21 A/V Home Theater
package to turn your home into a theater. In addition
to enhancing the sound of a video source, like your TV
or VCR, the YHT-21 also superbly reproduces audio
sources, such as a CD player or a cassette deck.
This Quick-Connect Guide will help you get started.
Study the speaker system plan (below), and then use
the interconnect diagrams (on the following pages) to
connect the receiver and speakers to your system.
For the video portion, you will need a hi-fi stereo VCR or
laser disc player and a television or monitor. Refer to the
Yamaha R-V703 Owner’s Manual, as well as those that
came with your other components, for complete instruc-
tions and cautions. Be sure to turn off all power while
making connections.
Save this Quick-Connect Guide for future reference.
NOTE: Label the end of each speaker wire (i.e., left rear, right
front, etc.) before connecting them to the A/V receiver. For wire
runs over 30 feet, use larger 18- or 16-gauge speaker wire.
• Velcro (for secure fastening of NS-AC2A on TV)
• Toggle bolts, molly anchor screws, or sheet metal
screws (for securing NS-A76A speakers to walls)
NOTE: If you are unsure of how to securely and safely fasten
speakers to a wall, please contact a reliable source about the best
type of hanger for your particular wall's construction. Secure
installation is the purchaser's responsibility.

CONNECTING A 5.1-CHANNEL DECODER
If you own a 5.1-channel decoder (or a unit which
incorporates a 5.1-channel decoder), you can connect
its discrete outputs to the R-V703 as shown below.
• To hear playback of a stereo or mono audio source
or one encoded with Dolby Pro Logic Surround*,
connect the unit (e.g., DVD player) to the DVD/LD
(or TV/DBS) AUDIO SIGNAL input terminals.
• The discrete signals feeding to the R-V703 cannot be
recorded by a tape deck, MD recorder, or VCR. To
record programs from a source (e.g., laserdisc
player), connect the source unit to the DVD/LD (or
TV/DBS) AUDIO SIGNAL input terminals.
• If your audio system does not include a subwoofer
(i.e., SUBWOOFER input terminals are not used), set
signal routing on the 5.1-Channel Decoder so that
the LFE channel feeds both LEFT and RIGHT MAIN
output terminals. For details, refer to the owner's
manual for your 5.1-Channel Decoder unit.
