How to Use This Manual

This manual is for the VSX-D938TX/D908TX/D908TX-G Audio/Video Multi-Channel Receiver.
This manual is divided into two main sections which will tell you how to setup and use the unit :

PREPARATION

First carry out the tasks below in this “Before You Start” section to prepare the remote control, then connect
the receiver to your other components as described in “Connecting Your Equipment” (p.8). Take special care to
connect your digital equipment like DVDs and LDs players properly to be able to take advantage of the receiver’s
surround sound systems.
To learn about a specific button, control, or indicator, see “Displays and Controls” starting on p.18.

SET UP

Performing the tasks in “Surround Sound Set Up” (p.27) is essential to get proper surround sound.

OPERATION

To play some music or soundtrack refer to “Basic Playback” on p.38. “Using the Tuner” (p.50) explains how to
use the radio of this unit. Doing the operations in “Remote Control of Other Components” (p.54) is highly
recommended so you can use this unit’s remote control for all your components. “Using Other Functions”
(p.66) explains the other possibilities of the receiver.

AA drycell batteries

(("AA" IEC LR6) × 2)

3

CAUTION!

Incorrect use of batteries may result in such hazards as leakage and bursting. Observe the following
precautions.

• Never use new and old batteries together.

• Insert the plus and minus sides of the batteries properly according to the marks in the battery case.

• Batteries with the same shape may have different voltages. Do not use different batteries together.

Operating other PIONEER
components

Connecting an optional control cord allows you to
operate other PIONEER components simply by
pointing the receiver’s remote control at the remote
sensor on the front panel of the receiver. The
receiver then sends the remote control signals to the
other devices via the CONTROL OUT terminal.

• You can also control PIONEER
components (and those made by other
manufactures) by pointing the receiver’s
remote control directly at the respective
component. This type of operation does
not require control cords. All you have to
do is recall the appropriate preset code
(see P.79 (VSX-D938TX), P.83 (VSX­D908TX/D908TX-G)).

• If you use a remote control hooked up via
the CONTROL IN jack with a control cord,
you will not be able to use this unit’s
remote control.

Operating range of remote
control unit

The area in which you can use the remote control to
operate the VSX-D938TX/D908TX/D908TX-G is fairly
large. To use, point the remote control toward the
remote sensor on the front panel of this unit while
within the range shown below.

Remote control may not function properly if:

• There are obstacles between the remote
control and the remote sensor.

• Direct sunlight or fluorescent light is
shining onto the remote sensor.

• The receiver located near a device
emitting infrared rays.

• Operated simultaneously with another
remote control which uses infrared rays.

Connecting Your Equipment

Audio Components

To begin set up, connect your audio components to the jacks as shown below. These are all analog connections
and your analog audio components (turntable, cassette deck) use these jacks. Remember that for components
you want to record with you need to hook up four plugs (a set of stereo ins and a set of stereo outs), but for
components that only play (like a turntable) you only need to hook up one set of stereo plugs (two plugs). To use
DTS surround sound features you must hook up your digital components to the digital inputs but it is also a good
idea to hook up your digital components to analog audio jacks. If you want to record to/from digital components
(like an MD) to/from analog components, you must hook up your digital equipment with these analog
connections. See p.10-11 for more on digital connections.
When connecting your equipment, always make sure the power is turned off and the power cord is
disconnected from the wall outlet.

NOTE

• Only the VSX-D938TX has a 2 RF IN jack.

• The arrows indicate the direction of the audio signal.

Connecting Your Equipment

Video Components

Connect your video components to the jacks as shown below. Regarding digital video components (like a DVD),
you must use the analog connections pictured on this page for the video signal but in order to use Dolby Digital
you should hook up their audio to a digital input (see the next page). It is also a good idea to hook up your digital
components with analog audio connections as well (see the previous page). To cover all possible laser discs a
DVD/LD player or LD player requires an analog connection (as shown here) and two digital connections (see the
next page).
When connecting your equipment always make sure the power is turned off and the power cord is
disconnected from the wall outlet.

Japanese designation “S2” on the VSX­D938TX/D908TX/D908TX-G but they are
simply S-video jacks.
However, if you use S-video cords for your
video hook ups you must also hook up your
TV with S-video connections. Conversely, if
you use regular composite video cords for
video hook ups, you should use them for
your TV as well.

Connecting Your Equipment

Digital Connections

In order to use Dolby Digital/DTS soundtracks and MPEG audio, you need to make digital audio connections. You
can do this by either coaxial or optical connections (you do not 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, it is a
matter of matching like with like (for example, the coaxial out from the component to coaxial in on the receiver).
The VSX-D938TX/D908TX/D908TX-G has two coaxial and two optical inputs for a total of four digital inputs. For
the VSX-D938TX, a DVD/LD player or LD player should be connected to a digital jack and the special AC-3 RF
jack (if the LD has one) as well as a pair of analog jacks (see the previous page). Connect your digital
components as shown below. There is one digital out jack which is marked PCM/
only) OUT. If you connect this to the optical input on a digital recorder (currently these include MD, DAT and CD­R) you can make direct digital recordings with this unit.
When connecting your equipment, always make sure the power is turned off and the power cord is
disconnected from the wall outlet.

Connecting Your Equipment

Speakers

A full complement of six speakers is shown here but, naturally, everyone’s home set up will vary. Simply
connect the speakers you have in the manner described below. The VSX-D938TX/D908TX/D908TX-G will work
with just two stereo speakers (called “front” speakers in the diagram) but the receiver is designed to be used
with at least three speakers.
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 receiver match those on the speakers.
When connecting your equipment, always make sure the power is turned off and the power cord is
disconnected from the wall outlet.

The VSX-D938TX/D908TX/D908TX-G has two speaker systems, A & B. A is the main system supporting
the full complement of surround sound speakers. If you switch on both A & B speaker systems, only
front speakers and the sub-woofer will be audible. No sound will come from the center or surround
speakers but multi channel sources will be down-mixed to the active speakers so no sound will be lost.
Similarly, if you choose just the B system, you will only hear the front speakers connected to the B
system and multi channel sources will be down-mixed to these two speakers.

Connecting Your Equipment

Speaker placement

If you have a multiple speaker arrangement the placement of the speakers is extremely important. To achieve
the best possible surround sound, install your speakers as shown below. Make sure all speakers are installed
securely to prevent accidents and improve sound quality. Be sure to consult your speaker manuals for the best
placement of the speakers. Some speakers are designed to be floor-standing but others benefit greatly from
speakers stands which raise them off the floor.

Front

Left

Surround

Left

• Install the left and right front speakers at equal distances from the TV.

• When installing speakers near the TV, we recommend using magnetically shielded speakers to
prevent possible interference such as distortion in the color of the TV screen. If you do not have
magnetically shielded speakers and notice discoloration of the TV screen, place the speakers farther
away from the TV.

• Install the center speaker above or below the TV so that the sound of the center channel is localized
at the TV screen.

CAUTION:

When installing the center speaker on top of the TV, be sure to secure it with tape or some other
suitable means. Otherwise, the speaker may fall from the TV due to external shocks such as
earthquakes, and it may lead to endangering those nearby or damaging the speaker.

• If possible, install the surround speakers slightly above ear level.

• It may be difficult to obtain a cohesive surround effect if the surround speakers are installed farther
away from the listening position than the front and center speakers.

Connecting Additional Amplifiers

Although the VSX-D938TX/D908TX/D908TX-G has more than sufficient power for any home use, it is possible to
add additional amplifiers to your system. If you want to use separate amplifiers to power your speakers, make
the connections shown below.
When connecting your equipment always make sure the power is turned off and the power cord is
disconnected from the wall outlet for all the eqiuipment.

Surround Sound Set Up

On Screen Display

There are a number of possible ways to hook up the receiver to your video components like a DVD player and
hook up to your receiver to your TV, but some of them will not allow you to use the on-screen display of this
unit. To avoid this one simply needs to follow two rules.
1 Always use the same type of video cords to hook up your video components to the receiver as you use to

hook up the receiver and your TV. For example, if you use composite video cords to hook up your DVD and
the receiver, use composite video cords to hook up the receiver to your TV. If you use S video cords to hook
up your DVD and the receiver, use S video cords to hook up the receiver to your TV.

2 Always make sure your TV is set to the appropriate input channel on your TV (for example, video 1). Your TV

may have a number of input channels and if you do not select the proper one you will not be able to use this
receiver’s on-screen display. If you are unsure how to choose an input channel for your TV, refer to the
manual which came with your TV.

You might, for example, use both composite and S video cords to hook up your video component with this
receiver and then use composite video cords to hook up this receiver to your TV. This arrangement would still
NOT let you see the on screen displays from this receiver on your TV. The best idea is just to use one type of
video cord for all your video component and TV hook ups.

Switching video system between PAL and NTSC

This receiver is able to use two types of video systems for its OSD (on screen display) and you need to set the
receiver to the type of video system you have, either PAL or NTSC. If you do not match the system on the
receiver with your home system no OSD will appear on your TV. People with multi-system TVs, don’t need to
worry about changing the setting. If necessary, follow the instructions below to switch the type of video
system.

wSTANDBY/ON

LOUDNESS

VSX-D938TX

Put the receiver in STANDBY mode.

2

While holding down the LOUDNESS button press the
STANDBY/ON button. The video system type, either
”PAL“ on ”NTSC,“ appears in the display. It will be
shown for about seven seconds and then the receiver
reverts to normal operating mode.

Be careful to press the LOUDNESS button and NOT the DIRECT
button, which will accidentally clear all your speaker settings (see
warning p.29-30).

Setting Up for Surround Sound

Surround Sound Set Up

To ensure the best possible surround sound, be sure to complete the following set up operations. This is
particularly important when using the DTS,

2 (Dolby) Surround sound and MPEG (VSX-D938TX only) modes.

You only need to make these settings once (unless you change the placement of your current speaker system
or add new speakers, etc.). These set up operations use your TV to display the settings and choices so be sure
your TV and receiver are properly hooked up.
