• Headphone Output: A 6.35mm (1/4 inch) jack for connecting headphones.

Operating Modes

The Audiolab 6000A offers three primary operating modes, selectable via the MODE knob:

• Integrated Mode: This is the standard mode where the 6000A functions as a complete integrated amplifier, handling both pre-amplification and power amplification.
• Pre-Power Mode: In this mode, the pre-amplifier section is bypassed, allowing the 6000A to act solely as a power amplifier. This is useful when connecting an external pre-amplifier or an AV receiver's pre-outs.
• Pre-Amplifier Mode: The 6000A functions as a standalone pre-amplifier, sending its output to an external power amplifier. The internal power amplifier section is disengaged.

Ensure the correct mode is selected for your system configuration. Accidental changes to the mode knob can render the amplifier non-functional until the correct mode is re-selected.

DAC Filters

The integrated ESS 9018K2M DAC offers selectable digital filters to fine-tune the sound to your preference or the characteristics of the audio source. These filters can typically be accessed through the unit's menu system (using the SEL or MODE knob to navigate and select).

• Fast Filter: Often provides a more detailed and precise soundstage, suitable for well-recorded music.
• Slow Filter: Can help to tame harshness or boosted high frequencies in certain recordings, offering a smoother sound.
• Phase Filter: May be used to adjust phase characteristics, potentially improving the overall smoothness and naturalness of the sound, particularly with older recordings.

Experiment with these filters to find the setting that best complements your music and listening environment.

Remote Control

The Audiolab 6000A comes with a remote control for convenient operation. The remote allows control over input selection, volume adjustment, mute, and other menu functions. Familiarize yourself with the remote's layout for optimal use. Note that some buttons on the remote may be designed for other Audiolab products and may not have a function with the 6000A.

Maintenance

To ensure the longevity and optimal performance of your Audiolab 6000A, follow these maintenance guidelines:

• Cleaning: Dust the unit regularly with a soft, dry, lint-free cloth. For stubborn marks, lightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals or abrasive materials, which can damage the finish.
