5. Installation

5.1 Placement

Place the Audiolab 9000A on a stable, level surface away from direct sunlight, heat sources, and excessive moisture. Ensure there is adequate space around the unit for ventilation.

5.2 Connexion des enceintes

1. Ensure the 9000A is powered off and unplugged from the mains.
2. Connect your loudspeakers to the speaker terminals on the rear panel (refer to Figure 4.3). Ensure correct polarity: red (+) to red (+) and black (-) to black (-).
3. Tighten the binding posts securely, but do not overtighten.

5.3 Connexion des sources audio

Le 9000A offre diverses options d'entrée :

• Analog Inputs (AUX1, AUX2, AUX3): Use RCA cables to connect analog sources like CD players, tuners, or tape decks.
• Entrée XLR symétrique : For high-quality analog sources with XLR outputs.
• Entrée phono (MM) : Connect your turntable directly to this input. Ensure your turntable has a Moving Magnet (MM) cartridge.
• Digital Inputs (COAX1, COAX2, OPT1, OPT2): Connect digital sources such as CD transports, media streamers, or TVs using coaxial or optical cables.
• PC USB (USB B): Connect your computer for high-resolution audio playback.
• Bluetooth : Attach the supplied antennas to the rear panel for optimal Bluetooth signal reception.

5.4 Connexion d'alimentation

Once all audio connections are made, connect the supplied power cord to the IEC inlet on the rear panel and then to a suitable mains power outlet.

6. Mode d'emploi

6.1 Mise sous/hors tension

Press the power button on the front panel or the remote control to switch the unit on or off. The display will illuminate upon power-on.

6.2 Sélection des sources

Use the "SELECT" rotary control on the front panel or the source buttons on the remote control to cycle through the available input sources (AUX1, AUX2, AUX3, XLR, Phono, COAX1, COAX2, OPT1, OPT2, PC USB, Bluetooth).

6.3 Contrôle du volume

Adjust the listening volume using the "VOL" rotary control on the front panel or the Volume Up/Down buttons on the remote control.

Modes de fonctionnement 6.4

The 9000A offers three distinct operating modes, selectable via the menu:

• Integrated Mode: This is the default mode, where the pre-amplificateur et puissance amplifier stages are combined. Use this for connecting digital and analog sources directly to the 9000A and driving a pair of speakers.
• Pre-Power Mode: This mode disconnects the pre-amplificateur et puissance amplifier stages. The 9000A can then be used solely as a power amplifier (e.g., connected to an AV processor) or to insert external signal processing between the pre-out and power-in connections.
• Pre Only Mode: In this mode, the 9000A functions solely as a pre-amplifier, outputting the processed signal via its pre-amplifier outputs to an external power amplifier.

6.5 Filtres numériques

For digital inputs, the 9000A provides user-selectable digital filters to optimize the response to suit the source file and partnering equipment. Access these options through the unit's menu system.

6.6 Connectivité Bluetooth

1. Ensure the Bluetooth antennas are connected to the rear panel.
2. Select "Bluetooth" as the input source on the 9000A.
3. Sur votre appareil mobile (smartphone, tablette, ordinateur portable), activez le Bluetooth et recherchez les appareils disponibles.
4. Select "Audiolab 9000A" from the list to pair. Once paired, audio from your device will stream wirelessly to the amplifier.
5. The 9000A supports aptX HD, AAC, and LDAC protocols for high-quality wireless audio.

6.7 Sortie casque

Connect your headphones to the 6.35mm (1/4 inch) headphone jack on the front panel. Connecting headphones will automatically mute the main speaker outputs.

7. Entretien

• Nettoyage: Use a soft, dry, lint-free cloth to clean the unit. Do not use abrasive cleaners, waxes, or solvents.
• Ventilation: Vérifiez régulièrement que les ouvertures de ventilation sont dégagées de poussière et de débris.
• Relations: Ensure all cables are securely connected. Loose connections can affect sound quality.
• Stockage: Si vous devez entreposer l'appareil pendant une période prolongée, débranchez-le de l'alimentation électrique et rangez-le dans un endroit frais et sec.
