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.

Manufactured under license from Dolby Laboratories Licensing Corporation. Additionally licensed under one or more of the following patents: U.S. 3,632,886, 3,959,590; Canadian numbers 1,004,603 and 1,037,877. "Dolby", Pro Logic and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation.

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.

If the tape or processor loop of your amphfier has been used up by the connections to the Xeta 2, then your cassette deck should be cormected to the TAPE IN © and TAPE OUT ® of the Xeta 2. The monitoring of the tape deck, provided it is a 3 head model, is carried out by use of the TAPE button on the Xeta 2.

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.

Figure 4

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.

OUT). If you are not using the TAPE IN for your cassette deck it may be used for another line level source such as a CD player.

® TAPE OUT - Connect this output to your cassette deck’s input (usually labelled RECOPJD

or IN).

Figure 5

® LD - Connect this input to your LASERDISC'S video output. This input is also compatible

with CD-I or a Video CD player.

® SAT - Connect this input to your satelhte TV decoder's composite video output.

® VCR OUT - Connect this output to your VCR's video input.

@ VCR IN - Connect this input to your VCR's video output.

® AUX - This input can be used for the video output of a camcorder, or a second VCR.

Note : Any of the above inputs can also be used to accept the video output of a TV tuner,

such as the Arcam Delta 150.

® MONITOR OUTPUT - Connect this output to your TV’s composite video input. Most

TVs only have SCART sockets; others use a phono socket or BNC connector. You will need a suitable lead or use an adaptor to make this connection. If in doubt consult your dealer. Advice on SCART pin connections is given on page 11 of this handbook.

■ Note that the MONITOR OUTPUT and VCR OUT on the Xeta 2 remain active even in standby mode, to enable unattended recordings to be made on your VCR.

FRONT PANEL FUNCTIONS

FRONT PANEL CONTROLS

(These functions are also controllable via the remote control handset.)

® INPUT INDICATORS - indicate which input is currendy selected.

® MODE INDICATORS - Indicate the current operating mode of the Xeta 2 as selected by

the mode switches.

Pro Logic. The indicator above the selected switch will glow green.

@ POWER SWITCH - Switches the Xeta 2 frill on or to standby mode. In standby mode you

can make unattended VCR recordings from an AV source onto your VCR.

■ The Xeta 2 cannot be switched on via the remote control after being manually turned off".

FRONT PANEL DISPLAYS

@ P^MOTE - This is the window for the infiia-red remote control receiver. It is not a push

button! Ensure it is not obscured or conmiands from the remote control handset will not be received.

® FUNCTION INDICATORS - Indicate that the named functions have been selected via

the remote control (see page(s) 9, 10 for more details). The CAL (calibration) frght flashes in SET UP MODE and hghts in normal use when centre speaker is off.

® TAPE MONITOR INDICATOR - indicates that the TAPE MONITOR is selected when

illuminated.

If the POWER LED flashes amber during normal use and the speaker outputs are lost, 'SPEAKER PROTECTION ACTIVE' appears on the TV screen. It may be due to the amplifier overheating. Check tiiat the amplifier is properly ventilated. The unit should reset within 2-3 minutes after it has cooled down.

It may also be caused by an output overload. This may be due to using the Xeta 2 at high volumes into low impedance loudspeakers or if there is a short circuit on the loudspeaker(s) or speaker cables (see FAULT FINDING GUIDE on page(s) 12,13 for more details).

If the fault is due to an overload of some sort the unit will not reset unless you first disconnect the mains supply by removing the mains lead or switching the power off at the wall socket. If the cause of the problem is not removed before restoring the power again the protection circuitry within the Xeta 2 will reactivate on power up. If the POWER LED continues to flash amber after carrying out the checks in the FAULT FINDING GUIDE, switch the unit off and contact your Arcam dealer for help,

SWITCHING ON AND SET UP

So you've wired everything up, what next?

First check all connections again to make sure there are no loose wires or plugs in wrong sockets, check your speakers for any shorts between terminals and turn the volume control down on your main stereo amplifier. Sv^dtch your TV on and select the relevant A/V input on the TV (i.e. the

one connected to the Xeta 2). Svdtch on the amplifier that you are using to drive your front left

and right speakers.

Switch the Xeta 2 POWER on via the front panel button. Select the source that you want to hsten to via the Xeta 2's input selectors and ensure that the source is playing.

With a video comiection from the monitor output of the Xeta 2, your TV should display "Arcam Xeta 2 POWER ON" for about 6 seconds if the correct video input has been selected on your TV. Increase the volmne level of the Xeta 2 and you should hear sound from the selected source coming from your loudspeakers. Dependent on the set up you are using you may need manually to adjust the volume control on your main amplifier in order to hear sound from the left and right channels.

If this is not the case, try other inputs and/or recheck your system connections. The FAULT FINDING GUIDE on page(s) 12, 13 will also help you. Once your system is working it is important to balance it for your components and the room environment.

SET UP MODE : SYSTEM BALANCING

No two A/V systems are alike; levels need to be equalised for the loudspeakers you have, and each source optimised for best performance. SET UP MODE allows you to adjust and to store these settings. If the amplifier was installed by your dealer this should have been done as part of the installation process. The stored settings can be recalled by pressing the red RESTORE button on the remote control handset.

If you have a TV with a composite video input follow the set up instructions that follow. Otherwise follow the instructions for BASIC SET UP on page 8.

If your dealer has not installed the unit or you wish to modify the stored settings then select the SET UP MODE by pressing RESTORE followed quickly by + in the mode section of the remote

control handset (the + key also has a small red square printed above it to help you remember the key). This wUl get you into SET UP MODE.

The cahbration LED on the fi-ont of the Xeta 2 wUl flash slowly and your TV screen should show a menu screen something like this:

CENTRE SPEAKER (not available in stereo mode) - Do as above, selecting from the following:

Normal - For a standard centre channel loudspeaker. Phantom - For no centre loudspeaker. This mode may be of benefit if your left and right

loudspeakers are of very high quality and you prefer a simple system without a centre speaker. Wideband - For larger centre loudspeakers capable of working down to low frequencies (usually 50Hz or below).

NOTE: In DOLBY 3 STEREO mode you do not get the Phantom option.

N.B. When selecting centre speaker after previously selecting Stereo mode, the display will remind you of 'NO CENTRE MODE' at the bottom of your TV screen. This also applies on Test Tone.

TEST TONE (not available in Stereo mode) - Selecting TEST TONE will produce a sequential burst (approx. 2-3 seconds) of noise through your speakers starting with left, centre, right and then rear. You should adjust the CENTRE and REAR volumes via the remote control until you are happy that all loudspeakers sound equally loud at your Hstening position. Unless you are using a power amplifier or an A/V Delta 290 in A/V mode to drive the front left and right speakers, you wiU have to adjust the volume level of the main ampHfier in order to hear the test tone through these speakers. This may mean setting the volume to halfway or more on its rotation. This is an ideal test for making sure all your speakers are connected properly. Pressing "+" on the remote advances the sequence immediately. Pressing on the remote wiU make the sequence go backwards. The noise sequence will stop when you press DOWN to move another menu line.

SET UP MODE - Page 1

Using the remote control handset push the UP or DOWN keys REMOTE CONTROL

MODE: - Use the - or + keys to select the sound mode in which you normally wish the unit to

operate for the selected source. Choose between the following options:

Dolby Pro Logic - For füll surround sound decoding including rear channel loudspeakers. Dolby 3 Stereo - Enhanced stereo mode using centre, left and right loudspeakers and no rear

loudspeakers.

Stereo - For stereo hi-fi use.

repeatedly to select the required line on your TV screen. This will

be highlighted on selection. Use the - or + keys to adjust the option

shown on the righthand side of your TV screen.

In Dolby 3 Stereo Mode - The display reminds you 'NO SURROUND MODE' and you get no test tone in the rear speakers.

IIP TRIM - Sets the input sensitivity of the Xeta 2 to optimise the performance of the surround decoding circuits (Not applicable to the TAPE input).

The TV screen will look like this:

The picture shows two peak reading bargraph level meters and an adjustable 'trim volume' setting below.

The available range is between -16dB and OdB in IdB steps.

Play back a recording from the source you have selected. Aim to peak just into the white bars above the arrow during the loudest parts of music or fihn. The exact setting is not critical. You should repeat this process for each source that you have. AH input trim settings are remembered by the Xeta 2, so that when switching between different inputs such as SAT, Laser Disc, VCR etc. they all phy at the same volume (assuming that's how you've set them, of course). Note that with

some low output sources it may not be possible to hit the peak area on the meter; this will not adversely afreet the performance. Because the input trim meters are more sensitive to mid or low frequency sound, you should try to set these levels with soundtracks which have good mid and low frequency content. In the unlikely event that you are unable to trim dovm the input sufficiendy from a particular source to avoid the white bars, then you may need to reduce the output level of

this source by some external means.

You can set the MODE (i.e. DOLBY PRO LOGIC etc.) for each input of the Xeta 2, except

TAPE, at this stage. Select the required input source (e.g. SAT) and then push the remote

control’s UP button three times. Now set the required MODE for that input. If required, the

HALL and CINEMA EQ settings can also be saved for the individual inputs at this stage by

selecting them via the remote control.

DELAY TIME- Surround information is delayed to the rear channels for psychoacoustic reasons.

The range is adjustable between 15 and 30 milliseconds (ms), and is commonly set at 20ms for most

installations. The optimum delay time does depend on the Hstening position. Use the charts below

and opposite to determine the delay time for your room's size and seating position. For example,

when the distance from the front speakers to the Hstening position is 3 metres and the distance from

the rear speakers to the Hstening position is 1 metre, the optimum delay time will be 20 ms.

SET UP MODE - Page 2

Now press DOWN on the remote control to get to the second page of the SET UP menu.

AMPLIFIER: You are given four choices for the main (front left/right) ampHfier:

OTHER - Any integrated ampHfier or preamplifier POWER AMP- Any power ampHfier STD D290 - Arcam Delta 290 ampHfier, s/no. less than 9935 A/V D290 - Arcam Delta 290 ampHfier, s/no. 9935 onwards.

If your ampHfier is listed above then select that one. If not choose OTHER unless your ampHfier is remote controUable and uses RC-5 remote control codes. In this case select STD D290.

CONNECTION:

You may choose between TAPE LOOP or LINE I/P (POWER AMP if AMPLIFIER is set to POWER AMP).

Pressing the UP and DOWN buttons will change the mode e.g. Dolby Pro Logic etc. and the front panel indicators will change accordingly.

Select the CONNECTION that you intend to use in your system.

The choices you make above determine how the Xeta 2 responds to commands from the Xeta 2 remote control handset. For more information see the section marked Amplifier/Connection

Choices on page 10. POWER UP VOLUME (not available ifPOWER AMP has been selected) - Use the "+" and

buttons, not VOLUME UP/DOWN, to set this volume level. Provided you are Ustening to a source at the time you will be able to hear the level changing as you make adjustments. Note it is not possible to set this level to ftdl volume. The Xeta 2 will reset to this preset level if it is switched off and on again. This is to avoid accidental high volume levels on switch on.

EXIT AND SAVE - When everything has been set to your satisfaction press the DOWN key to

highlight this line. Press "+" to exit and ’SAVED’ will flash up on the display.

The Xeta 2 has now been set to your personal settings. By pressing RESTORE on the remote control you can recall these settings, overriding adjustments made during nomial use.

Further system tuning will be required if you have a subwoofer. You will need to adjust its level control and tune the crossover frequency to integrate smoothly with your main loudspeakers. Try a variety of source materials to help you make these adjustments until you are happy with the sound. The subwoofer instmctions may also provide advice on system balancing. Do not be concerned if the level ac^ustment on the sub-woofer needs to be set near maximum to achieve the right balance.

If you now press the FUNC button again the 'CAL' indicator will flicker and you are able to trim the input levels (see INPUT TRIM on page 6).

The MUTE indicator will Hght if the input level is too high. You should set the INPUT TRIM to cause the MUTE indicator to light occasionally. This is best done on music or a soundtrack with a high bass content.

Pressing FUNC again EXITS AND SAVES the BASIC SET UP menu.

ALTERNATIVE METHOD

It is possible to view the on screen graphics on a TV without a composite video input provided

you have a video recorder (VCR) with a composite video input.

Connect the MONITOR OUT of the Xeta 2 to the composite video input of yom VCR. Switch your VCR to this input (see your VCR handbook) and your TV to the charmel which you use to view your VCR. Now by pressing RESTORE quickly followed by '+' on the Xeta 2 remote control you should be able to view the frill SET UP MENU (see page 6).

After completing the set up for all inputs you should discormect the lead from the MONITOR

OUT of the Xeta 2 and connect it to the VCR OUT of the Xeta 2 . You should now have a

connection betwen VCR OUT of the Xeta 2 and the 'Video In' input of your video recorder. This will enable you to record other video sources, satellite, laserdisc, etc. The On Screen Graphics win no longer be visible.

BASIC SET UP MODE

If your TV does not have a composite video input you can do a basic set up of the Xeta 2 in one of two ways, depending on your other equipment.

To set up the Xeta 2 without being able to view the On Screen Graphics follow the instructions below. For an alternative set up method which enables you to view the On Screen Graphics in set up mode only refer to the next section,

To enter the BASIC SET UP mode press the FUNC button followed quickly by the ’+' button on the remote control. The CAL indicator will flash to indicate you are in SET UP MODE.

You will hear in noise through the speakers in sequence as you are in the TEST TONE cycle. The noise will sequence in the following order left, centre, right, rear and can be heard for about 2-3 seconds on each one. If you want to step through the sequence quicker than this then use the '+’ or buttons.

You shoiild adjust the rear and centre volimie via the remote so that all the loudspeakers are equally loud from your hstening position.

ALTERNATIVE METHOD, and figure 6.

REMOTE CONTROL COMMANDS

Most functions on the remote control are straightforward and obvious to use. The On Screen Graphics win confirm their actions on your TV screen.

The functions described below will allow you to optimise the way you use your system. Letters in the left hand colunm refer to the remote control drawing on the inside front cover of this handbook.

® INPUT SELECTORS: These select the required input on the Xeta 2. They may also select

inputs on the main ampHfier if it uses compatible control codes based on the Philips RC-5 standard.

® POWER: Switches the amplifier on or off firom standby. The POWER LED glows amber

if the Xeta 2 is put into 'standby' via the remote. If it is switched off manually the LED glows red. When the Xeta 2 is in standby mode " XETA 2" is displayed on the TV screen to remind you that the TV is stiU on.

■ The Xeta 2 cannot be switched on via the remote if it has been switched off with the POWER button

if your TV does not have a composite video input and enables you to set some parameters without On Screen Graphics.

® AUTOBALANCE: With AUTOBALANCE switched on, active circuitry ensures that the

surround decoder receives equal levels of left and right signal. This is most important for proper surround decoding. With videotapes the left and right channels may be mismatched,

or may vary along the tape, therefore we recommend that AUTOBALANCE be used with

video tape sources.

■ STEREO is real stereo. For optimal hi-fi sound quality the Dolby Surround processing circuits are actually bypassed by relays when the Xeta 2 is swatched to stereo. This prevents the stereo signal being affected by unnecessary circuits and retains maximum fidelity. Use STEREO for your regular hi-fi sources or for non surround encoded video material.

The + and - buttons have no function during normal operation and are used only in SET

UP MODE.

surround encoded sources. It can be useful for recordings of five perfomiances where the added ambience firom the rear channels can increase your involvement in the performance. The FIALL LED on the firont panel will indicate when this is on. You can trim the amount of HALL effect by use of the REAR +/- level buttons®.

®,® BALANCE: In SET UP MODE this function is used for manual balancing of the input

signal to optimise the surround decoding for some sources. In normal use the BALANCE affects the left/right speaker balance.

■ To set the input balance you must be in SET UP MODE. Make sure that you are in Dolby Pro Logic or Dolby 3 Stereo mode and switch AUTOBALANCE off. Find a surround encoded source with plenty of speech present. Switch the centre charmel off via the remote

(the Cafibration LED will fight). The speech should almost disappear; if not, alter the balance to the left or right by using <BAL and BAL>. Find the position that gives the minimum speech output or "dialogue null" in the centre channel. The input balance is now optimised and you can switch the centre speaker back on for use.

■ The input balance control operates in IdB steps which are indicated on the On Screen Graphics. Equal levels are indicated by "L=R".

Switching AUTOBALANCE off bypasses the active circuitry for AUTOBALANCE. Signal

balancing (if required) must then be done using the BALANCE buttons on the remote

control during set up. Note that AUTOBALANCE cannot fiiUy compensate for a maximum

left or right balance setting made in normal use.

® CINEMA: Switching on Cinema EQ (Equalisation) reduces the treble output of the centre

channel. Cinema EQ can improve films recorded with excessive treble and sibilance. The

front panel CINEMA EQ LED will fight when this mode is on.

® MODE keys: The UP and DOWN buttons will cycle the Xeta 2 through the three primary

operating modes as shown below:

■ DOLBY PRO LOGIC feeds sound information through the rear speakers and the firont speakers (L, R & C). Use this mode for surround encoded sources. Video tapes and discs

with surround encoding can be identified by looking for the Dolby Surround logo.

■ DOLBY 3 STEPÆO feeds sound information through the firont speakers (L, R & C), but not the rear speakers. You should use either this mode or stereo mode for non surround encoded video sources. Stereo mixes vary so that it is worth trying this and stereo mode to see which one you prefer. If your system has no rear loudspeakers, use this mode for surround encoded material.

@ CENTER +/-: Trims the level of the centre speaker.

® CENTRE OFF: Switches the centre channel off or on. Useful for setting the dialogue null

during manual input balancing. See BALANCE and AUTOBALANCE above for more details. Switching the centre channel off is also useful for Karaoke and for nulling out unwanted sports conunentators.

® DISPLAY: Pressing this switch once switches on the volume level indicator to give you an

idea of the current volume setting. This indicator is less bright than other graphics in order to be less intmsive when watching the TV . Pressing DISPLAY a second time switches off the On Screen Graphics. Pressing the button a third time will switch the On Screen Graphics back on and the screen will display status information of all functions for your information. This infomiation is displayed for about 6 seconds, and you can hold the button down to keep the status infomiation displayed for longer. After this the normal On Screen Graphics mode is then active. If you go into SET UP MODE with the display off, the display will come back on in order to view the OSG. It remains active when you come out of set up.

AMPLIFIER MODES (selected on screen in SET UP MODE)

® REAR +/-: Trims the level of the rear surround speakers.

Note: Not all films are encoded fiar surround identically. It is usefiil to trim the rear or firont levels shghtly for some recordings.

® REAR OFF: Switches the rear channel off or on. Usefid to demonstrate the effectiveness of

the surround effect.

® RESTORE: Restores your amplifier to the condition saved in the set up mode. This is very

useful if the centre and rear levels have been adjusted after set up, as it restores them to the saved values. The operating mode and any functions such as Cinema EQ that were saved during set up are also restored.

Note: To enter the SET UP MODE press RESTORE quickly followed by'+' (mode), see SET

UP MODE selection on page 6 for more details.

MONITOR in and out. Dependent on how you have set up the Xeta 2, you may need to use the SHIFT button simultaneously with the VOLUME, MUTE, POWER or INPUT selector buttons to control functions on the Xeta 2. It can also be used to control these functions on the Arcam Delta Black Box 500 outboard digital to analogue converter unit.

OTHER/ POWER AMP

STD D290, LINE

STD D290,

TAPE

Only the 4 video input buttons i.e. LD, SAT, VCR and AUX affect the Xeta 2. The other 4 input buttons have no effect. V^en the L & R outputs of the Xeta 2 are connected to the line input of an integrated amplifier, selecting any non-video input on the remote (e.g. CD) will mute the Xeta 2's outputs. When connected to a power ampHfier, all non video input commands cause the Xeta 2 to switch to "AUX".

To adjust the volume on the Xeta 2 you must hold down the SHIFT button

and press the appropriate button. Use the input selection buttons on the remote control to select the required Delta 290 input. Pressing an A/V source input button e.g. SAT will also change the Delta 290 input selector as below:

SAT = PHONO/AUX LD = AV VCR = TAPE 1 TAPE = TAPE 2

The AUX button has no effect. The On Screen Graphics (OSG) show which input on the Delta 290 has been selected. Pressing volume up or down without using the SHIFT key affects the Delta 290 volume control. SHIFT AUX switches the Xeta 2 to the AUX input.

As above but there are no OSG for Delta 290 input selections.

® MUTE: Mutes and un-mutes the sound firom aU channels. The word ‘MUTE’ will be

displayed in the top left hand comer of the TV screen when MUTE is activated.

® VOLUME: This operates the master volume control for the Xeta 2. It may also control the

volume of some amplifiers which use the same remote control codes. Note that a VOLUME command will automatically un-mute the Xeta 2 if MUTE is on.

If you hold either VOLUME button down, the volume will vary in steps of about 3dB. For a finer adjustment press and quickly release the button. The volume scale on the OSG does not have the same resolution as the actual volume control and so the pointer on the OSG may not move every time.

AMPLIFIER/CONNECTION CHOICES

The Xeta 2 uses the Philips RC-5 remote control protocol. It responds to commands firom the remote control handset in different ways depending on the wiring cormection (TAPE LOOP or LINE) and the type of amplifier you have chosen firom the on screen set up menu. The handset is the same as used in the Arcam Xeta One integrated

KPJ amplifier. This has 8 inputs so some of the buttons may not function in the way you might at first expect. The anomoUes are set out opposite.

A/V D290, LINE

You must use SHIFT simultaneously with the input buttons to change Xeta 2 inputs. Use the input selection buttons without SHIFT to select inputs on the Delta 290. If AUX on the Delta 290 is selected the OSG displays input, i.e. 'AUX' followed by 'D', to show that it is the Delta 290's AUX input you have selected.

If you select AUX on the Xeta 2 the OSG will display AUX followed by 'X' to indicate it is AUX on the Xeta 2 you have selected.

A/V D290, Just press the required input button and the Xeta 2 or Delta 290 will do the rest. TAPE Selecting an input on the Delta 290 with the remote control will automatically

switch the Xeta 2 to AUX input in order to fisten to the selected source and process the signal as required.

The A/V input cannot be selected on the Delta 290 via the remote handset, without also changing the Xeta 2 input setting. This is because the RC-5 code for LD and A/V are the same. The Xeta 2 switches to the LD input when you press LD and the Delta 290 switches to the A/V input. To hsten to a source through the Delta 290's A/V input you will then have to select AUX on the Xeta 2, as it will not do this automatically.

GENERAL ADVICE WHEN USING THE XETA 2

USING AN OUTBOARD DAC

Turn your TV volume down or mute its internal speaker, otherwise it will upset the balance of surround sound created by the Xeta 2.

When positioning your front and centre speakers aim to get them all at the same height. Ensure that the centre loudspeaker is magnetically shielded. Check with your dealer if in doubt.

Don't underestimate the importance of the centre speaker. Much of the soundtrack of a film is

dialogue, which is normally routed through the centre charmel loudspeaker. A poorly designed centre speaker will result in compressed dynamics, distortion and loss of detail. Speakers used for

left, right and centre charmels should be of a similar tonal balance or come from the same

manufacturer.

For video recording, the signal path is maintained provided the Xeta 2 is connected to a Hve mains supply. The On Screen Graphics do NOT appear on the VCR video output.

On some pre-recorded video material the On Screen Graphics may appear in a sHghtly different position from normal. This is due to the non-standard characteristics of the video signals used by certain suppHers of pre-recorded tapes eg. Macrovision ™. Changing over from PAL to NTSC video sources will also cause this to occur for a few seconds until the Xeta 2 recognises and adapts to the new signal format.

Chcking noises from inside the unit are quite normal during use. These are caused by muting relays operating momentarily when switching modes or inputs on the amphfier.

The digital output from a Laser Disc player (which is normaUy an optical connection) may be fed into an external digital to analogue (DAC), e.g. an Arcam Black Box 50 or 500, for improved sound

quahty.

CABLES

Cables can make or break a system. The quahty of interconnects (audio, video and digital) and speaker cables you use will be a limiting factor on the performance of your hi-fi/home cinema system. The better the cable the better the sound. Cables from the AudioQuest range are ideal partners for the Xeta 2. As a rule of thumb plan to invest around 10% -15% of the value of your equipment in cables.

SOURCES OF SURROUND ENCODED MATERIAL

The majority of films on video, laserdiscs and broadcast TV have surround sound - look for the Dolby Surround logo.

Surround material requires a stereo source which can be any of the following:

An FM radio tuner - some plays are recorded in Dolby Surround A stereo TV or TV tuner (NICAM) A hi-fi stereo or NICAM video recorder A laserdisc player A stereo sateUite receiver or cable system Dolby Surround encoded video games

UPGRADE PATHS AVAILABLE WITH THE XETA 2

The Xeta 2 can be used with an Arcam Delta 290P power amphfier to drive the front left and right

speakers. For even better results you can bi-amplify the front speakers using 2 x Delta 290Ps, whilst a third Delta 290P could be added to bi-amp the centre speaker. The Xeta 290P, a version of the

Delta 290P which is an exact match for the Xeta 2's graphics, is available to order from your dealer.

CONNECTING THE XETA 2 TO EXTERNAL POWER AMPLIFIERS

The Xeta 2 can be used as the control unit with external power amplifiers being employed for higher output power or for improving the sound quahty. Connect your additional power amplifier(s) to the appropriate sockets as described below.

amphfier or amphfiers for the rear channel speakers if required.

® SUB OUT - Provides a mono output for an active (powered) sub woofer. If used with a

separate power amphfier and subwoofer loudspeaker then a proper bass crossover filter should

be used.

® MAIN FRONT OUT - connect the power amplifier(s) which will be driving your front pair

of speakers to these sockets.

The Xeta 2 is compatible with aU of these.

SCART PIN CONNECTIONS

European video equipment frequently features SCART type connectors for audio and video connections. SCART tc( phono leads are easily obtainable for intercoimection. The information below is provided if you need to make up your own connections.

FAULT FINDING SECTION

INITIAL ADVICE

Please ensure that you have read the instructions and are operating the equipment accordingly.

Check aU cables to your speakers and other components for any loose or incorrect connections.

Ensure that the rest of the components making up your system are operating correctly. A fault can

occur in another component or connecting lead that might appear to be a Xeta 2 problem.

Make use of the status infomration on the On Screen Graphics by switching the Display on via the remote handset. The infomration will tell you what modes the Xeta 2 is set to.

If any problems stiU persist you may find the following suggestions usefid.

If you still have problems after carrying out the checks Hsted then contact your Arcam dealer or use our helpHne number shown on the inside firont cover between 9am and 5pm BST.

THINGS TO CHECK:

ADVICE:

SYMPTOM:

ADVICE:

SOUND FROM CENTRE AND REARS ONLY

• Is the amplifier driving the front speakers switched on and the correct input selected?

• Is the volume on this amplifier turned up?

SOUND NOT COMING OUT OF REAR SPEAKERS

• Is Dolby Pro Logic selected? The relevant LED should glow green.

• Are the rear speakers cormected properly?

• Have rear speakers been switched on (via the remote)?

• Are you replaying Dolby Surround encoded material?

• Has the rear volume been turned up?

• Is your source operating in stereo mode?

Even on Dolby Surround encoded material, sound does not come out

of the rear speakers all of the time; the amount of rear level also varies

from film to film.

SOUND COMING OUT OF REAR SPEAKERS WHEN

MATERIAL IS NOT DOLBY SURROUND ENCODED

There is nothing to check here. Sometimes on normal broadcasts phase differences in the recordings can confuse the surround steering

circuitry allowing certain signals to be heard from the rear speaken.

You can of course switch off the rear speakers using the remote

control handset, or switch the Xeta 2 to stereo mode.

SYMPTOM:

THINGS TO CHECK:

ADVICE:

NO SOUND FROM ONE LOUDSPEAKER

• See points fisted above.

• Is the balance control set to centre position?

• Is the input balance set to L=R (via the remote)? For the centre charmel: ensure phantom mode has not been selected

in SET UP MODE.

For the centre or rear channel: ensure these are not switched off via the remote. Also try adjusting the channel volume.

To check a source component, swap the phono leads over (L -with R) at the source equipment only. If the fault changes over to the other channel, then the fault is in the source component.

SYMPTOM:

THINGS TO CHECK:

NOTE:

UNABLE TO MONITOR VIDEO FROM THE XETA 2 ON YOUR TV

• Is your TV s-witched to the correct AV input?

• Have you connected the TV correctly to the video MONITOR OUT socket on the Xeta 2?

• Have you selected the right video input via the source selector?

• Is the Xeta 2 properly switched on?.

If you can monitor the video signal but cannot display On Screen Graphics then press DISPLAY on the remote to switch them back on.

XETA 2 DOES NOT RESPOND TO REMOTE CONTROL

COMMANDS

• The Xeta 2 may be set up to work using the SHIFT button simultaneously with another button to prevent a 'clash' with the remote control codes of other hi-fi units.

Try holding down SHIFT whilst pressing the remote control buttons.

• Check that the unit is set up correctly (see AMPLIFIER & CONNECTION instructions in SET UP MODE page(s) 7, 8).

• Check that the Xeta 2 is switched on and the POWER LED is green.

• Check the remote receiver is not obscured.

• Check the batteries in the remote control are in the correct way round or try replacing them with new ones.

XETA 2 REMOTE HANDSET OPERATES ANOTHER HI-

FI UNIT’S VOLUME, MUTE AND SOURCE SELECTION

AS WELL AS THOSE OF THE XETA 2

Change AMPLIFIER type in the SET UP menu to STD 290 (see page 7). You will now have to hold down the SHIFT button whilst pressing

the VOLUME, MUTE or INPUT selectors to afect the Xeta 2 only.

The problem is caused by both units responding to the standard RC-5 remote control signals used. By holding down the SHIFT button an

alternative code is used for the Xeta 2.

SYMPTOM:

THINGS TO CHECK:

SYMPTOM:

THINGS TO CHECK:

NOTE:

HIGH LEVELS OF DISTORTION AND CROSSTALK

• Check that the INPUT TRIM has been set correctly (See page 6 for more details).

It is possible to overload the audio inputs of the Xeta 2 if the input signal is 3 volts rms or greater. As a point of reference CD players have maximum output level of about 2 volts rms so you are unlikely to encounter this problem. However this could happen if you are using a preamphfier to drive the Xeta 2 and have connected the 'Preamp Outputs' to the Xeta 2 instead of the 'Tape Out'.

"SPEAKER PROTECTION ACTIVE" DISPLAYED ON TV

& THE POWER LED FLASHING AMBER

• Check that the Xeta 2 is well ventilated as the protection may have been activated due to overheating. The unit wfil reset after 2-3 minutes when it has cooled dovm sufficiently.

The problem may also be caused by an output overload. This may be due to using the Xeta 2 at high volumes into low impedance loudspeaken or if there is a short circuit on the loudspeaker(s) or speaker cables.

If you have been using the Xeta 2 at high volmnes then you may have to reduce the volume to prevent reoccurence of the problem. You should also have your cable and loudspeakers checked out by a competent person before recormection to the system again.

If the fault is due to an overload of any sort the unit will not reset unless you first disconnect the mains supply by removing the mains lead or switching the power off at the wall socket. If the cause of the problem is not removed before restoring the power again the protection circuitry within the Xeta 2 will reactivate.
