Information to User
Alteration or modifications carried out without appropriate authorization may invalidate the user's right to
operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interfer-
ence in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instructions, may cause harmful interference to radio commu-
nications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turn-
ing the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
­ Reorient or relocate the receiving antenna.
­ Increase the separation between the equipment and receiver.
­ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
­ Consult the dealer or an experienced radio/TV technician for help.
If the socket outlets on the associated
equipment are not suitable for the plug
supplied with the product the plug must be
removed and appropriate one fitted.
The cut-off plug must be disposed of as an
electrical shock hazard could exist if
connected to a socket outlet.
WARNING: TO PREVENT FIRE OR SHOCK
HAZARD, DO NOT EXPOSE THIS APPLIANCE TO RAIN
OR MOISTURE.
Maintenance of External Surfaces
· Use a polishing cloth or dry cloth to wipe off dust
and dirt.
· When the surfaces are dirty, wipe with a soft
cloth dipped in some neutral cleanser diluted five
or six times with water, and wrung out well, and
then wipe again with a dry cloth. Do not use
furniture wax or cleaners.
· Never use thinners, benzine, insecticide sprays
or other chemicals on or near this unit, since
these will corrode the surfaces.
Power cord CAUTION
Handle the power cord by the plug. Do not pull out
the plug by tugging the cord and never touch the
power cord when your hands are wet as this could
cause a short circuit or electric shock. Do not place
the unit, a piece of furniture, etc., on the power cord,
or pinch the cord. Never make a knot in the cord or tie
it with other cords. The power cords should be routed
such that they are not likely to be stepped on. A
damaged power cord can cause a fire or give you an
electrical shock. Check the power cord once in a
while. When you find it damaged, ask your nearest
PIONEER authorized service center or your dealer for
a replacement.

1 Hooking Up Your DVD Player & TV
In order to use Dolby Digital/DTS soundtracks which are at the heart of home theater you need to hook up your
DVD player with digital audio connections. You can do this by either a coaxial or an optical connection, you don't
need to do both. The quality of these two types of connections is the same but since some digital components
only have one type of digital terminal you need to figure out which yours has and hook it up to the appropriate
terminal on the receiver. In order to do this you will need the proper cable. For coaxial connections you can use a
regular RCA stereo cord or the specially-made coaxial cords, they have the same type of plugs. For optical
connections you will need a special optical cord which you can buy at your local stereo store. Also hook up the
video connection of your DVD player, the analog audio (for recording the audio on DVDs, use regular RCA stereo
cords), and your TV (it's easiest to use a regular composite RCA video cords) as shown below. It is important
that you hook up your TV (or monitor) in order to see a video image as well as the on screen displays (OSDs)
shown by this receiver (for more on p.16-17). We also recommend hooking up your all your digital components
to analog audio jacks. For this you can use regular RCA stereo cords.
Coaxial Digital Connection
If your DVD player has a coaxial terminal (not a PCM-only output) for the audio out hook it up using this terminal.
Follow the diagram below. This is the best scenario, as you will be able to follow the default settings of this
receiver and won't need to assign the digital inputs.
Optical Digital Connection
If your DVD player has an optical terminal (not a PCM-only output) for the audio out you can hook it up using this
following the diagram below. You will need to assign the digital input (tell the receiver which input you put your
DVD digital audio into). See page 5 for this.

2 Speaker Connections
Home theater is designed to be setup with five, or seven speakers (front left & right; center; surround left &
right; and, optimally, surround back left & right) and a subwoofer but you can use this receiver with fewer
speakers. Hook up the speakers you have to the A speaker terminals on the back of the receiver. If you only
have two speakers hook them up as "FRONT." If you have three hook up the single speaker as "CENTER." Follow
the diagram on p.19 in order to hook up all your speakers. A center speaker is very important for watching films
because the dialog comes from the center speaker in digital soundtracks. If you do not have a CENTER
speaker you must tell the receiver the CENTER channel is OFF or when you listen to digital soundtracks
you won't hear any dialog. Use the instructions on page 32-33 in order to do this.
Follow the diagram below to hook up an additional amplifier in order to use surround back speakers. These
speakers are important to hear all the sound channels on new, eight channel home theater DVDs. The diagram
below also explains how to hook up a subwoofer which provides realistic bass sounds.
Make sure you connect the speaker on the right to the right terminal and the speaker on the left to the left
terminal. Also make sure the positive and negative (+/­) terminals on the amplifier match those on the speakers.
