3 This Handbook covers 4 different models, as follows: An integrated amplifier A power amplifier The DAVE (Digital Audio Video Enter tainment) amplifier The MARC (Multi Area Remote Control) amplifier SAFETY There are 19 safety items, set out on page 25 of this Handbook. For your own safety, and to ensure that your amplifier works properly, we strongly recommend that you read them. SOUND CUTS OUT FOR NO APPARENT REASON If the temperature of the internal heatsinks rises above a safe level, then a thermal cut out inside the amplifier will operate. The POWER INDICATOR on the front panel will turn orange and the protection system will temporarily remove the power to the speakers. The system will reset itself as the heatsinks cool down. When playing a heavily recorded CD it is possible to drive the A22 at full po wer despite the fact that the volume is not at maximum. This is because of the high output voltage from a CD player. AMPLIFIER DOESNT SWITCH BACK ON All amplifiers have a 'protection mechanism' which will be activated if you switch the unit on again immediately after turning it off. The mechanism may stop it being turned back on. If the mechanism activates, wait 30 seconds, then tr y again. For ease of use, this handbook has been divided into 4 sections. Integrated amplifier Power amplifier DAVE (Digital Audio Video Enter tainment) amplifier MARC (Multi Area Remote Control) amplifier Each of the sections has a shor t introduction to the product, followed by an 'User Guide' which is primarily for users who have had their system installed by their dealer or supplier. Following the 'User Guide' is a section describing 'Advanced Features' (depending on the complexity of the product). Finally for customers wishing to set up their own system, a section called 'Setting Up'.

A microprocessor is at the hear t of the amplifier. It performs several impor tant functions. It switches the amplifier on or off from standby mode and mutes the two sets of speakers individually as well as the pre-amp output. It is also responsible for the remote bus and infra red remote input. Parameters can be selected, and displayed, on the built in graphic display enabling easy set up of the amplifier and simple source selection. In addition, the amplifier uses LED markers to indicate the primar y source which is in use. In addition to a full suite of audio line level inputs, there is also a high quality optional MM/MC phono stage.To protect your amplifier, the microprocessor monitors the heatsink temperature and RF content of the speaker outputs. In the event of the amplifier being over driven, it can activate the automatic speaker protection circuits and it can repor t fault conditions to the main display. dn POWER Switches the unit on and off. The unit can also be switched into standby by use of the remote control handset. do POWER INDICATOR This will initially glow amber. After a few seconds, it will glow green. When the indicator glows amber, the speakers are disconnected and an internal protection circuit is activated. The power indicator will turn red if the unit has been put into standby mode by use of the remote control. Under cer tain conditions the power indicator may flash and a fault condition will be shown on the display dp . If this happens y ou should unplug the mains lead of the unit and leave the unit for a few minutes before re-connecting. If the fault condition persists unplug and contact your Arcam dealer. dk SP1 Selects or de-selects the main (upper) pair of speakers. Push the b utton in to select. dl SP2 Selects or de-selects the secondar y (lower) pair of speakers. Push the button in to select. Impor tant note: If both switches are turned off the amplifier will appear not to work, as all speakers will be switched off! cr VOLUME Adjusts the volume level of the loudspeakers, pre-amp out and headphones. The volume can also be controlled with the Remote Control Handset. As the volume knob is not motorized the knob will not move when adjusted remotely. If you spin the knob quickly it will not change the volume. This is to prevent accidentally setting the volume too high. NOTE ON VOLUME CONTROL SETTINGS It is impor tant to realise that the position of the volume control is not an accur ate indication of the power delivered to your loudspeakers. The amplifier will often deliver its full power long before the volume control reaches its maximum position par ticularly when listening to heavily recorded compact discs. Ho wever the amplifier also has to be capable of giving full power output from much lower level sources, such as tuners and cassette decks. Using these sources, the volume control setting may be much higher before distor tion (audible overload) sets in. BALANCE Press CONTR OL cq ,turn the volume knob to the desired balance, then press CONTROL again to fix the balance you have selected. cq CONTROL This button cycles (or steps) through the functions that can be controlled by the volume knob. This can be either volume (the default setting) or balance. If you have a DAVE or MARC, there are several other functions. Refer to those sections of this handbook. cs ENTER TAINMENT (SOURCE) SELECTORS These buttons select the source (i.e. Radio (TUNER), Compact Disc (CD) etc. you wish to listen to. dq REMOTE RECEIVER The remote receiv er is behind the FMJ badge. Make sure the remote receiver is not covered or signals from the Remote Control Handset will not be received. dm HEADPHONES SOCKET Accepts headphones rated between 8 ohms and 2k ohms fitted with a 1/4 stereo jack plug. If you wish to listen on headphones only, use SPl and SP2 (if necessar y) to mute the speak ers. The headphone socket is always active. Integrated amplifier - User Guide 4 Circled numbers in the text, e.g. 7 , refer to the numbers on the pictures. If your integrated amplifier HAS NOT been installed for you, you should read the section entitled Setting up before using the User Guide. cn co cp cq dk ct dl dm dn cs cr do dp dq PHONO/AUX MODE CONF RM RECORD CONTROL CD TUNER AV DVD VCR PROCESSOR2 TAPE 1 SP1 SP2PHONES A22 INTEGRATED AMPLIFIER POWER Vol olum e C CD INTRODUCTION IN USE 5 Integrated amp - Using the Remote Control Dont forget to fit the two AAA batteries supplied and ensure they are inser ted correctly into the back of the remote control before using it. The Remote Control sends a message to an infrared receiver which is located behind the FMJ badge on the front of the amplifier. Do not place anything in front of the badge or the Remote Control may not work. VOLUME AND (MUTE) Press + to increase volume or – to decrease the output volume of the amplifier. Press to mute the speaker connections and preamp outputs. Both tape outputs and the headphone socket remain active. Mute is disabled either by pressing again, or by adjusting the volume. CD CONTROLS These offer basic controls of Arcam CD players, such as the FMJ CD23. DAVE REMOTE CONTROL If you have a DAVE amplifier, you will have the the CR9000 Remote Control as shown in the DAVE amplifier section of this handbook. That Remote Control allows you to operate the integrated amplifier plus some basic functions of an Arcam or Philips based CD player or Tuner. TUNER These buttons are used to control tuner functions. Note that the FM/DAB lights indicate into which mode you are switching the remote control. The lights only illuminate for five seconds to conser ve batter y power. If neither light is illuminated this does not mean that the remote control is not working! SOURCE SELECTION BUTTONS These operate in the same way as the source selectors on the front panel of your integrated amplifier. DISP Cycles through the settings Bright, Off and Dim. Turning the display Off generally gives a slight improvement in sound quality. SP1 AND SP2 These buttons allow you to select and deselect the main(SP1) and secondar y (SP2) sets of speakers attached to your amplifier (see page 4). POWER/STANDBY Toggles the amplifi er between standby mode and full power mode. The power indicator light next to the power button on the front panel is red if the amplifier is in standby, amber while the amplifier is powering up (this only takes a few seconds) and green when the amplifier is powered up. If you have an integrated amplifier or MARC amplifier, you will have a Remote Control similar to the one shown below. This CR-389 Remote Control gives access to all functions available on the front panel of FMJ amplifiers. It also has controls to operate Arcam CD players, AM/FM tuners andDAB tuners. The Remote Control transmits Philips RC-5 type codes. OTHER AMPLIFIER FUNCTIONS Note that greyed-out buttons on the remote control diagram are of use with other Arcam amplifiers.

21 20 The following modes will be available: Stereo, Dolby Digital, DoIby Pro Logic, Dolby 3 Channel, DTS, Digital Stereo. Note: Some modes may be disabled dependant on the actual input signal. Modes can be selected by use of the front panel MODE button or the MODE buttons on the remote handset. The modes that are selectable are dependant on the actual source material being played. These are shown below: PCM DIGITAL INPUT(CD SIGNAL): Digital stereo, Dolby Pro Logic Digital, DoIby 3 Channel (if no rears are selected). DOLBY 2 CHANNEL: Dolby Digital Stereo, Dolby Digital Pro Logic, Dolby Digital 3 channel (if no rear speakers are selected) DOLBY MULTI CHANNEL : Dolby Digital stereo mx (mix down), Dolby Digital XXX eg 3/2/.1 DTS 2 CHANNEL: DTS Digital Stereo DTS MULTI CHANNEL : DTS Digital Stereo Mx, DTS Digital XXX ANALOGUE: Stereo analogue, Dolby Pro Logic - analogue, Dolby 3 Channel (if no rear speakers are selected). Source material, par ticularly DVDs, will var y from disc to disc in the number of surround channels encoded. Frequently, you may find only stereo has been encoded, par ticularly on older movies. Below are some of the more commonly available formats. If you wish to listen to a source that is not a 2 channel stereo source you MUST change the mode to a stereo mode in order to hear all of the sound correctly on the headphones. For example if you are listening to a DVD player in 5.1 channel mode you would have to set the mode to Dolby Digital Stereo mixdown when listening on headphones. If you dont you will not be able to hear any of the main dialogue signals on your headphones because this is a centre channel signal. Adequate ventilation MUST be provided for the DAVE amplifier, and it is strongly recommended that it is not stacked with other products, par ticularly additional power amplification. The DAVE surround decoding circuitr y requires a temperature controlled environment in which to function correctly. If the internal temperature of the unit reaches a cer tain point, a cooling fan will begin operating to cool the circuitr y. You may hear this as a ver y quiet whirring sound coming from the amplifier. This is normal. If the temperature continues to rise the amplifier may shut itself down to allow it to cool. If this happens the unit will switch into standby mode and Fault Condition Protection will be shown on the display. When the unit has cooled down sufficiently the unit will automatically switch out of standby again. In addition, fan cooling is also provided for the two main output channels. This cooling is only activated above a cer tain temperature, and when there is a signal present, so any fan noise will be masked as far as possible, by the loudspeaker output. It is only possible to record from an analogue source. You cannot record from any digital source. If you wish to record from a CD player connected to one of the digital inputs you will have to make a connection from the analogue outputs of the CD player directly to your recorder or to the analogue CD inputs of the Alpha 10. In the latter case you can then record the CD signal by pressing the front panel RECORD button followed by the CD input button. To record from a laser disc player connected to the AV analogue inputs of the amplifier first press the RECORD selector followed by the AV button. This will route the audio signals of the Laser Disc to the VCR Audio Record Out sockets and the video signal to the composite or S Video VCR OUT socket (S Video, Composite video). Note: you may not be able to record the video signal if it contains Macrovision copy prohibit signals. The amplifier will automatically switch to the best source signal when an input is selected if DECODE mode has been set to 'AUTO'. For example if you have a CD player connected to the digital input and also an analogue connection to the CD inputs the unit will default to the digital signal when CD is selected. To force the unit to the analogue input press and hold the CD button until Analogue is sho wn on the OSD or front panel display. This will take about 4-5 seconds. If you press the CD button again it will reselect the CD digital input signal.

This Remote Control Handset can be programmed to send messages to other devices in your home enter tainment system. The Remote Control therefore has a universal numbering system to cross reference a button to a function. This is required as the words printed on the Remote Control and the programmed functions may not be the same. Refer to the CR 9000 Operating Manual for full instructions. The adjacent diagram will help you to acccess the functions of other equipment using the universal reference numbers in the Operating Manual supplied.
