INTRODUCTION
Thank you for purchasing this Arcam product.
The Xeta 2 is a sophisticated Home Cinema Dolby Pro Logic processor which offers superb sound
and picture quahty. It must be used with an integrated amphfier or a power ampHfier to drive the
front left and right speakers.
The Xeta 2 is a httle more compHcated to cormect up than an ordinary amphfier. Please read these
instructions carefully and refer to the relevant diagrams on the following pages. Inside the front cover
are diagrams of the Xeta 2's front and rear panels. Each input/output socket, function button and
indicator is clearly numbered. The numbers correspond with those given in the instructions.
For ease of use, the Xeta 2 is suppHed with the CR40 infra-red remote control handset. Many
functions are only available via the remote control.
The Xeta 2 uses On Screen Graphics (OSG) which are displayed on your TV screen via the
composite video MONITOR OUT ® connection, to show which functions have been selected and
which system adjustments have been set.
If your TV does not have a composite video or SCv^RT input it is not possible to view the On Screen
Graphics in nomial use, but it is stiU possible to use the Xeta 2 by following the BASIC SET UP
procedure on page 8 and figure 6.
SYSTEM CONFIGURATION
You may choose from one of three basic connection configurations when using the Xeta 2. These
are discussed below and illustrated in figures 1-3.
1. BASIC CONFIGURATION WITHOUT COMPOSITE VIDEO (see figure 1)
The On Screen Graphics are not visible in nomial use.The A/V source’s video signal is connected
directly to the TV either on composite video or by the remodulated (RF)connection. Dolby
decoding and processing is possible only with the A/V sources connected to the Xeta 2.

Figure 1
2. USING THE XETA 2 AS AN INPUT EXTENDER FOR AN SOURCES (see figure 2)
Figure 2 shows the suggested wiring for use with a power ampHfier (e.g. an Arcam Delta 290P,
Xeta 290P) Delta 290 integrated amphfiers up to serial number 9934 or any other integrated
amphfier without a spare tape monitor facihty.
Dolby decoding and processing is possible only on the audio from the A/V sources which are
connected to the Xeta 2. The video sources are routed through the Xeta 2 and the composite
video MONITOR OUT connection ® is made to the TV to enable the On Screen Graphics
to be seen.
You should also set the AV READY switch to AV READY (see your Delta 290 handbook for
details). Tbis bypasses the Delta 290's volume control when the PROCESSOR/ TAPE 2 input
is selected to allow the Xeta 2 to control the volume level of the system.
IMPORTANT NOTE: If you wish to optimise the signal path when hstening to audio only
sources you can switch the Delta 290 to the required input and release its PROCESSOR /
TAPE 2 switch. If you change the Delta 290 input via the remote handset the Xeta 2 wiU
automatically change to the AUX input. However unless you switch off the Xeta 2, or put it into
standby, it may also continue to respond to the VOLUME commands from the remote handset
which are directed at the Delta 290.
Under these conditions the volume control of the Xeta 2 can be inadvertendy set very high,
leading to very high sound levels when the Xeta 2 is switched back into the system. To minimise
this possibility you can continuously display the current volume setting of the Xeta 2 on your TV
screen by pushing the DISPLAY button on the remote handset. Additionally the Xeta 2 will
default to a factory set volume level of approximately one-third (22dB below the maximum)
when switching away from its AUX input to any video input, if the current setting is higher than
this default setting.
Figure 2
3. TAPE LOOP CONNECTION (see figure 3)
This allows Dolby Pro Logic decoding and processing of aU the sources cormected to both the
amphfier and the Xeta 2.
This is the suggested configuration if you are using an Arcam A/V Delta 290 (serial no. 9935
onwards) These units are recognisable by the PROCESSOR/ TAPE 2 button on the front panel
and a switch on the rear panel marked AV R^ADY/NORMAL. The tape out cormections of
your stereo amphfier are connected to the AUX input of the Xeta 2. This allows sources
connected to the stereo amplifier to be processed if required. The main front out connections of
the Xeta 2 are coimected to the tape in of the stereo amphfier in order to hear the left and right
front signals. The PROCESSOR/TAPE 2 button on the Delta 290 must be pushed in to enable
the signals to be processed via the Xeta 2.

MAINS SUPPLY CONNECTIONS
INSTALLATION
® Check that your mains supply voltage agrees with the voltage setting indicated on the rear panel
of the unit.
■ If your mains supply voltage is different, consult your Arcam dealer.
MAINS SAFETY
■ This product is normally supphed with a moulded mains plug already fitted to the lead. If for
any reason the plug needs to be removed, it must be disposed of immediately and securely, as it is a potential shock hazard when inserted into a mains socket.
■ If the plug is removed then the remaining lead must be wired as follows:
The blue wire must be connected to the terminal which is coloured blue or marked with the
letter N.
The brown wire must be connected to the terminal which is coloured brown or marked with
the letter L.
The green and yellow wire must be cormected to the terminal which is coloured green and yellow, or marked with the letter E or the safety earth symbol.
■ When replacing the fuse in the supphed moulded mains plug, the integral fuse holder/cover
must always be refitted. Use a 5 amp fuse (UK models only).
■ Warning: This apparatus must be earthed.
® Insert the lEC fine socket of the mains lead fuUy into the power inlet on the rear panel.
Connect the other end to your mains supply.
NOTE: Always switch the Xeta 2 on and off using the front panel POWER switch. When you are
installing the system you are advised to disconnect or turn down the volume level on your subwoofer
(if using one) before switching the mains supply to the Xeta 2 on at the wall socket. This will avoid
any unwanted cficks or thumps through your subwoofer.
The rear surround loudspeakers should ideally be placed behind the listening position or, if this is not
possible, then to either side. The object of the rear speakers is to produce a difiiise, room filling sound.
Locate the rear loudspeakers away firom you and above your head so that they do not fire directly into
your ears. The addition of a subwoofer to enhance the bass end of your system should also be
considered. The location of a subwoofer is less critical but should foUow the manufacturer's
recommendations.
LOUDSPEAKER CONNECTIONS (See figure 4)
The Xeta 2 only contains surround and centre ampHfiers. Your firont left and right speakers should
be cormected to your stereo integrated or power ampHfier.
■ Cormect the red (positive) cable temiinations of your speaker leads to the red temunals on the
Xeta 2 and the other cable terminations to the black terminals. If your speaker cables have
appropriate bare ends, the positive conductors can usually be identified by a ridge or coloured
marking. Ensure that no stray strands are allowed to touch another cable or the amplifier's casing. This can cause a short circuit and damage your ampHfier! The loudspeaker
terminals are marked as follows:
®,® SURROUND - Cormect your two rear surround speakers here. As the surround channel is
mono it does not matter which one is connected to left or to right.
®,® CENTRE - Cormect your centre speaker(s) here. In some systems, particirlarly where a large
screen TV is used (around 37" or larger), you may wish to use two centre speakers - one above
and one below the TV. Ensure the centre speakers(s) are magnetically shielded, or the pictures
on the TV tube coirld become pemianendy discoloured. Alternatively the two pairs of sockets
can be used to bi-wire one centre speaker if it has separate terminals for the bass and treble
drivers.
LOCATING YOUR LOUDSPEAKERS
A true Home Cinema set up confomiing to Dolby Surround requirements will need five loudspeakers
in order to recreate the surround sound experience: a firont pair, rear pair and a centre channel
loudspeaker.
If you have good quality stereo loudspeakers then you will probably wish to use these as the main
firont loudspeakers. They should be positioned roughly equidistant to, and either side of your TV and
typically 8-10 feet (2.4 - 3m) apart. The centre loudspeaker must be located close to your TV screen
so that the picture and centre sound come firom the same location. In a Home Cinema set up, the
centre speaker is very important, as much of the sound comes firom this source. Its sound balance
should be as similar as possible to the main stereo speakers.

CONNECTING YOUR SOURCE COMPONENTS
COMPOSITE VIDEO CONNECTIONS (See figure 5)
■ Audio inputs: Up to five different audio sources can be connected to the Xeta 2. Four inputs
are available for simultaneous audio and video, and one for audio only. AU inputs have the
same basic sensitivity and may be used witli equipment other than that labelled, if you need to
do so.
■ Video mputs: Up to four different video sources can be comiected to the Xeta 2 - VCR, Laser
Disc (LD), Satellite (SAT) and Auxihary (AUX). Tliis allows you to select the TV picture and
sound together and is particularly useful if your TV has only one video input.
LINE LEVEL AUDIO CONNECTIONS
■ Using a suitable pair of interconnect cables to connect each component, insert the red phono
plugs into the sockets labelled 'R' and the other plugs into the sockets labelled 'L', except for
the CENTRE and SUB OUT which require only one lead.
® SURROUND OUT - Provides two identical mono outputs for an external power ampUfier
or amphfiers for the rear channel speakers, if required.
(D SUB OUT - If you have an active (amphfied) subwoofer, connect it to this
output.
®MAIN FRONT OUT - Connect to the left & right fine inputs of an integrated amphfier, e.g.
'tape in', or to the inputs of a stereo power-amplifier. You must make a connection from these
sockets to another amphfier in order to hear the front left and right signals.
In order to display the On Screen Graphics menus used in setting up and cahbratir^ the unit
you must make a cormection from the composite (base band) video MONITOR OUTPUT
@ of the Xeta 2 to your TVs composite video input. If your TV does not have a composite
video input see page 8 for a BASIC SET UP method without the use of On Screen
Graphics. Note that a remodulated (R.F.) output is not available on the Xeta 2.
You wiU need a number of 75 ohm composite video cables terminated with phono plugs
to comiect your A/V equipment to the composite video inputs and outputs of the Xeta 2.
® AUX - This is a fine level input which can be connected to the audio outputs of an additional
A/V source unit. When the Xeta 2 is connected in an ampfifier’s tape loop then the AUX
input should be connected to the TAPE OUT connections of the main amphfier.
0 VCR IN - Comiect this input to your video cassette recorders (VCR's) audio output.
® VCR OUT - Connect this output to your video cassette recorder's (VCR’s) audio input.
® SAT - Connect this input to your SateUite TV decoder's audio output.
® LD - This input is compatible with Laser Disc (LD), Compact Disc Interactive (CD-I) or a
VIDEO CD player. Connect this input to the player's audio output.
■ TAPE CONNECTIONS - Use these sockets only if you have connected the Xeta 2 into the
tape loop of your main amphfier. If not, you should leave your tape deck connected to your
main amphfier.
