For your own safety, and to ensure that your amp

3、lifier 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 prot

4、ection 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 power despite the fact that the volume is not at maximum. This is because of the high output voltage fro

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 try again. For ease of

6、use, this handbook has been divided into 4 sections. Integrated amplifier Power amplifier DAVE (Digital Audio Video Entertainment) amplifier MARC (Multi Area Remote Control) amplifier Each of the sections has a short introduction to the product, followed by an User Guide which is primarily for users

7、 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).

It performs several important functions. It switches the amplifi

10、er 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 sim

11、ple source selection. In addition, the amplifier uses LED markers to indicate the primary 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 temper

12、ature 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 report 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 t

13、he 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

14、 mode by use of the remote control. Under certain conditions the power indicator may flash and a fault condition will be shown on the displaydp. If this happens you should unplug the mains lead of the unit and leave the unit for a few minutes before re-connecting. If the fault condition persists unp

Push the button in to select. dl SP2 Selects or de-selects the secondary (lower) pair of speakers. Push the button in to select. Important note: If both switches are turned off the amplifier will appea

16、r 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

17、 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 important to realise that the position of the volume control is not an accurate indication of the power delivered to your loudspeakers. The amplifier will o

18、ften deliver its full power long before the volume control reaches its maximum position particularly when listening to heavily recorded compact discs. However the amplifier also has to be capable of giving full power output from much lower level sources, such as tuners and cassette decks. Using thes

19、e sources, the volume control setting may be much higher before distortion (audible overload) sets in. BALANCE Press CONTROL 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

20、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 ENTERTAINMENT (SOURCE) SELECTORS These buttons select the source (i.e. Radio (TUNER), Comp

21、act Disc (CD) etc. you wish to listen to. dq REMOTE RECEIVER The remote receiver 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

22、 a 1/4” stereo jack plug. If you wish to listen on headphones only, use SPl and SP2 (if necessary) to mute the speakers.The headphone socket is always active.

24、ed amp - Using the Remote Control Dont forget to fit the two AAAbatteries supplied and ensure they are inserted 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 FMJbadge on the front of the amplifier

25、. 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 i

26、s 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.Tha

27、t 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 onl

28、y illuminate for five seconds to conserve battery 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

29、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 secondary (SP2) sets of speakers attached to your amplifier (see page 4). POWER/STANDBY Toggles the amplifi er betwe

30、en 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

31、 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 R

32、C-5 type codes. OTHER AMPLIFIER FUNCTIONS Note that greyed-out buttons on the remote control diagram are of use with other Arcam amplifiers. 76 cp TAPE RECORDING Note:The integrated amplifier must be fully powered up in order to record. Both sets of tape sockets are identical in sensitivity and suit

33、able for use with almost any type of recorder (cassette, hi-fi VCR, reel to reel, DAT, etc.) The entertainment source selected (i.e. Radio (TUNER), Compact Disc (CD) etc. will automatically be the signal you record (and is sent to both the VCR and PROCESSOR RECORD output sockets) unless you select a

34、nother source. To select another source, press RECORD.The display will first show RECORD SOURCE. Select an alternative input by pressing the appropriate button, (i.e. Radio (TUNER), Compact Disc (CD) etc.Your selected choice will show in the display.The display will indicate the selected recording o

35、ption for a few seconds and then revert back to showing the volume bar graph. Press RECORD twice to go back to RECORD SOURCE. If you are using the TAPE 1 sockets in processor mode.The signal selected will not go to both the VCR and PROCESSOR RECORD output sockets but go to the VCR/TAPE 2 instead.Thi

36、s RECORD button can also be used as a second zone selector, sending (a source signal at line level) to a second amplifier operating in another room in the house. TAPE TO TAPE COPYING (DUBBING) The integrated amplifier allows two way tape dubbing from TAPE 2 to TAPE 1 but NOT TAPE 1 to TAPE 2. For ex

37、ample, to copy from a cassette recorder connected to the VCR/TAPE 2 sockets to a cassette recorder connected to TAPE 1, first use the RECORD selector cpon the integrated amplifier to select RECORD :VCR.This routes the TAPE 2 signal to TAPE ls output.Then set the tape recorder connected to TAPE 1 soc

38、kets into its record mode and the other to playback mode to enable the transfer to take place. If you wish to monitor the transfer while it is taking place select TAPE using the TAPE1/PROCESSOR button ct. cn,co MODE & CONFlRM These buttons are only for use with optional modules such as the DAVE or M

39、ARC amplifiers. They have no function on their own in normal use on the basic integrated amplifier although MODE can be used to select processor mode, as described below. ct PROCESSOR/TAPE 1 This is tape loop to monitor a recording made on a 3 head cassette deck. It can also be used to connect to an

40、 external surround decoder such as the Arcam Xeta 2. Selecting this input overrides the other source selectors cs. To play back or to monitor the recording from a cassette deck attached to the PROCESSOR/TAPE 1 input press the processor button ct.TAPE is shown on the display. For use with an external

41、 processor the A22 can be put into processor mode by first selecting PROC and then whilst holding in the MODE button cnpress the PROC button ctagain.The display will now show PRO in place of TAPE. If the processor you are using is an Arcam Xeta 2 then press the PROC button again while holding in the

42、 MODE button so that PRO2 is displayed. The volume level of the integrated amplifier will now be fixed so that you can use the volume control of the external processor as a master volume control. Using the volume or mute buttons on the remote handset or the front panel control knob will have no effe

43、ct whilst in processor mode.The unit will return to processor mode whenever ctis pressed. Once in PRO2 mode the AV,TAPE 1,VCR and DVD buttons on the CR235 remote control will have no effect. This is because the Xeta 2 will also respond to these Remote Control codes and switch to the wrong input. If

44、you want to change the input back for use as a normal tape input hold the MODE button in and press the PROCESSOR button until TAPE appears on the display. CAUTION: Do not set the integrated amplifier in processor mode if you have a cassette deck or other line level source attached to the PROCESSOR/T

45、APE 1 input.This is because selecting processor mode input will send a fixed volume signal straight into the power amplifier which could damage your loudspeakers. NOTE: If you are using the integrated amplifier with an external processor, via the PROCESSOR/TAPE 1 loop you must set the vol- ume of th

46、e integrated amplifier so that you can see at least one segment of the volume level bar graph before switching to the PROCESSOR input. If you fail to do this you will not hear any sound from the speakers attached to the integrated amplifier.To obtain a sound again, reselect another input eg CD and t

47、urn the volume up slightly. Then reselect the PROCESSOR input. CAUTION Your amplifier generates heat in use. It is therefore most important to ensure adequate ventilation and not to obstruct the ventilation slots on the top of the unit as this could cause overheating. WRONG PLUG ? If the plug suppli

48、ed with the amplifier does not fit your power supply, see the section entitled Safety Guidelines for changing a plug, or contact your dealer to obtain a suitable power cord. Check that your mains supply voltage agrees with the voltage setting indicated on the rear panel of the amplifier at 1. If you

49、r mains supply voltage is different, consult your Arcam dealer or Arcam Customer Support on 01223 203203. PLUGGING IN Push the plug (IEC line socket) of the cable supplied with the amplifier, into the socket 2(POWER INLET) in the back of the amplifier. Make sure it is pushed in firmly. Push the plug on other end of the cable into your power supply socket. Your amplifier is fitted with loudspeaker terminals, to BFA, (British Federation of Audio) standard specification. The terminal will accept spade terminals, bare wires or a BFA plug. BFA plugs are available from your Arcam d
