Placing The Unit

 Place the ampliﬁer on a level, ﬁrm surface, avoiding

direct sunlight and sources of heat or damp.

 Do not place the PA720, PA240 or PA410 on top of a

power ampliﬁer or other source of heat.

 Do not place the ampliﬁer in an enclosed space such

as a bookcase or closed cabinet unless there is good provision for ventilation. The PA720, PA240 and PA410 are designed to run warm during normal operation.

 Do not place any other component or item on top

of the ampliﬁer as this may obstruct airﬂow around the heat-sink, causing the ampliﬁer to run hot. (The unit placed on top of the ampliﬁer would become hot, too).

 Do not place your record deck on top of this

unit. Record decks are very sensitive to the noise generated by mains power supplies which will be heard as a background ‘hum’ if the record deck is too close.

 The normal function of the unit may be disturbed by

strong electromagnetic interference. If this occurs, simply reset the unit with the power button, or move the unit to another location.

Interconnect Cables

We recommend the use of high-quality screened cables that are designed for the particular application. Other cables will have diﬀerent impedance characteristics that will degrade the performance of your system (for example, do not use cabling intended for video use to carry audio signals). All cables should be kept as short as is practically possible.

It is good practice when connecting your equipment to make sure that the mains power-supply cabling is kept as far away as possible from your audio cables. Failure to do so may result in unwanted noise in the audio signals.

EN-6

Power

The ampliﬁer is supplied with a moulded mains plug already ﬁtted to the lead. Check that the plug supplied ﬁts your supply – should you require a new mains lead, please contact your Arcam dealer.

If your mains supply voltage or mains plug is diﬀerent, please contact your Arcam dealer immediately.

Push the IEC plug end of the power cable into the power socket on the back of the ampliﬁer, making sure that it is pushed in ﬁrmly. Plug the other end of the cable into your mains socket and switch the socket on.

Operation

Switching On

The POWER button switches the unit on and oﬀ. The status indicator LED indicates the state of the ampliﬁer: it changes from red to orange then white if mains power is connected and the unit is switched on.

Pressing the STBY button while the unit is powered on, will place the PA720, PA240 or PA410 into standby mode. Press the STBY button again to bring the unit out of standby.

Automatic Standby

In order to comply with international regulations for consumer products, this unit is designed to enter standby mode if no user interaction and no audio input signal are detected for an extended period of time (default is 20 minutes). The unit can be brought out of standby by pressing the STBY button on the front panel, the trigger input or RS232 or ethernet command (if enabled, see “Network and RS322 in Standby” for more information)

The standby time out can be adjusted using either RS232 or IP control commands. Please refer to the PA720 / PA240 / PA410 RS232/IP control document, available for download from www.arcam.co.uk.

Alternatively pressing and holding the MUTE button will toggle the standby time out between OFF and 20 minutes.

The LED will ﬂash to indicate the setting change, red for OFF, green for 20 minutes.

Note: if the standby time-out is set to OFF, the automatic standby feature will be disabled.

Network and RS322 in Standby

In low power standby mode the network and RS322 functionality is disabled.

To enable network and RS232 in standby, send a control or status request command to the unit whilst it is powered on.

This will enable whichever control method was used when the unit is in standby.

Note: To indicate the unit is not in lowest power standby mode the LED will ﬂash brieﬂy when entering standby mode.

Note: Enabling network or RS232 control will increase standby power consumption. To restore the unit to the default low power standby consumption press and hold the STBY button for more than 3 seconds or restore the unit to factory defaults.

Muting the Output

The speaker outputs of the PA720, PA240 or PA410 can be silenced by pressing the MUTE button on either the front panel or by sending the relevent command via either the RS232 or network connection.

If the unit is muted, front panel power indicator will change to orange.

To cancel the mute, press the MUTE button again or send the relevent command via either the RS232 or network connection.

Mode switches

The various mode switches located on the rear of the PA720 and PA240 ampliﬁers allow you to conﬁgure your power ampliﬁer to your speciﬁc equipment setup. See “Connecting Sources and Loudspeakers” on page EN-13 for more information.

INPUT (PA720 and PA240 only)

This switch selects between the XLR and RCA phono inputs of the ampliﬁer. Select which ever connection method you are using to connect your preamp.

GAIN(PA240 only)

This switch allows the gain to be changed from standard Arcam gain of 31dB (which matches all Arcam ampliﬁers and receivers) to 26dB. This allows ﬂexibility to connect multiple PA240 ampliﬁers in diﬀerent modes to multiple speakers.

In normal set-ups this switch should be left at 31dB.

MODE (PA240 only)

This switch selects between the diﬀerent ampliﬁcation modes of the PA240.

STEREO (ST)

This is the standard stereo ampliﬁcation mode using two separate preamp inputs driving two separate speaker outputs.

DUAL MONO (DM)

This mode allows two separate speakers to be driven from a single preamp input.

Alternatively the two drivers of a single speaker can be bi-amped from a single PA240.

EN-12

BRIDGED MONO (BRIDGE)

This mode uses both channels of the PA240 to drive a single speaker. This the ultimate in high power, high ﬁdelity ampliﬁcation.

Notes On Making Speaker Connections

 Do not make any connections to any ampliﬁer while it is switched on. We recommend

that your ampliﬁer is completely disconnected from the mains supply before starting.

 Before switching your ampliﬁer on for the ﬁrst time after connecting to speakers, please

check all connections thoroughly. Ensure that bare wires or cables are not touching each other or the ampliﬁer’s chassis (which could cause short circuits), and that you have connected positive (+) to positive and negative (–) to negative. Be sure to check the wiring for both the ampliﬁer and the speaker.

 After making connections: switch the ampliﬁer on then gradually increase the volume

to the required listening level.

 If you are unsure as to how your system should be connected, please contact your

Arcam dealer who will be happy to help you.

Troubleshooting

Problem Check the following

No sound  The PA720 / PA240 / PA410 power ampliﬁer is correctly plugged in and

switched on.  Your audio/video source (e.g. pre ampliﬁer) is correctly connected.  The PA720 / PA240 / PA410 is not in protection mode, as described in

the next section.  The PA720, PA240 and PA410 is not muted.

Sound cuts-out unexpectedly The PA720 / PA240 / PA410 may enter a protection mode, depending on

the fault being detected. The front panel LED will indicate the fault type, according to the list below.

 FLASHING WHITE: The internal temperature of the unit reached an

unsafe level. Allow the PA720 / PA240 / PA410 to cool oﬀ.  FLASHING RED: The PA720 / PA240 / PA410 ampliﬁer detected a

speaker short circuit. Should this happen, please inspect all the

speaker cables to make sure none of them are shorted together. This

fault is very common when bare wires are being used to make speaker

connections.  FLASHING ORANGE: PA720 and PA240 only. The ampliﬁer detected a

DC oﬀset.

Following any of the faults described above, the ampliﬁer will turn itself oﬀ and power to the speakers will be removed. To continue using the PA720 / PA240 / PA410, the fault must be removed and the unit must be turned OFF then back ON.

Vue d’ensemble

Les amplicateurs Arcam PA720, PA240 and PA410

Les ampliﬁcateurs Arcam PA720, PA240 and PA410 oﬀrent une qualité sonore de premier ordre pour une reproduction optimale de votre musique.

Ces ampliﬁcateurs, fruits de nombreuses années d’expérience d’Arcam en conception d’éléments d’ampliﬁcation, utilisent les meilleurs composants et les meilleures pratiques d’ingénierie pour produire des ampliﬁcateurs qui oﬀriront de nombreuses années de plaisir musical et une opération ﬁable.

Avec une alimentation toroïdale, un châssis à amortissement acoustique, une technologie de classe G (PA240 et PA720), des étages de sortie à transistors parallèles (PA240) et des niveaux de distorsion et de bruit exceptionnellement bas, ces ampliﬁcateurs PA720, PA240 and PA410 sont tous capables de reproduire la musique avec toute son autorité et ses détails originaux. Soyez assuré que vous entendrez la musique comme l’artiste l’a prévu.

Les ampliﬁcateurs PA720, PA240 and PA410 sont conçus pour produire un niveau de performance qui donnera vie à la musique.

Placement de l’unité

 Posez l’ampliﬁcateur sur une surface plane et ferme,

en évitant les rayons directs du soleil et les sources de chaleur ou d’humidité.

 Ne le placez pas le PA720, PA240 or PA410 sur un

ampliﬁcateur ou une autre source de chaleur.

 Ne placez pas l’ampliﬁcateur dans un endroit fermé

comme une bibliothèque ou un meuble fermé à moins qu’il n’y ait une bonne circulation d’air. Le PA720, PA240 and PA410 est conçu pour produire de la chaleur lors de son fonctionnement normal.

 Ne placez aucun autre composant ou article sur le

dessus de l’ampliﬁcateur, car cela pourrait obstruer la circulation d’air autour du dissipateur thermique et provoquer un échauﬀement de l’ampliﬁcateur. (L’appareil placé sur le dessus de l’ampliﬁcateur deviendrait également chaud).

PA720

 Ne placez pas votre platine tourne-disques sur

cet appareil. Les platines tourne-disques sont très sensibles au bruit généré par l’alimentation secteur qui sera entendu comme un « bourdonnement » de fond si le tourne-disque est trop proche.

 L’opération normale de l’appareil peut être perturbée

par de fortes interférences électromagnétiques. Si cela se produit, réinitialisez simplement l’appareil à l’aide du bouton d’alimentation ou déplacez-le à un autre endroit.

Câbles de raccordement

Nous recommandons l’utilisation de câbles blindés de haute qualité, conçus pour l’application particulière. D’autres câbles auront des caractéristiques d’impédance diﬀérentes qui réduiront les performances de votre système (par exemple, n’utilisez pas de câbles destinés à la vidéo pour transporter des signaux audio). Tous les câbles doivent être aussi courts que possible.

Il est recommandé, lors du branchement de votre équipement, de veiller à ce que le câblage de l’alimentation secteur soit aussi éloigné que possible de vos câbles audio. Le défaut à suivre ces règles peut entraîner des bruits indésirables dans les signaux audio.

POWER AMPLIFIER

POWER

STANDBYMUTE

Alimentation

L’ampliﬁcateur est livré avec une ﬁche secteur moulée déjà montée sur le câble. Vériﬁez que la ﬁche fournie correspond à votre type d’alimentation – si vous avez besoin d’un nouveau câble secteur, veuillez contacter votre revendeur Arcam.

Si la tension d’alimentation de la prise secteur ou la ﬁche de votre appareil ne conviennent pas, veuillez contacter immédiatement votre revendeur Arcam.

Enfoncez l’extrémité de la ﬁche CEI du câble d’alimentation dans la prise de courant située à l’arrière de l’ampliﬁcateur, en vous assurant qu’elle est bien enfoncée. Branchez l’autre extrémité du câble dans votre prise secteur et mettez l’interrupteur à la position EN MARCHE.
