About the Audiolab 6000A

Eric A.

A solid integrated amplifier for stereo listening

Audiolab has been making audio components since the early 1980s, and the company's legacy of value and versatility can be seen in the 6000A integrated amp. It delivers a clean 50 watts per channel at 8 ohms, and it's 4-ohm stable, so it can drive a wide range of speakers. There's a high-current toroidal power transformer inside that offers super-clean sound, and a built-in premium ESS Sabre DAC that reveals important musical detail when you listen to digital sources.

Product Research


Discrete Class AB Amplification: The Audiolab 6000A's discrete Class AB power amp stage delivers 50W x 2Ch into 8 ohms or 75W x 2Ch into 4 ohms, with a maximum current delivery of 9 Amps into difficult loads. The output stage of the discrete power amp circuits uses a CFB (Complementary Feedback) topology, ensuring superior linearity and excellent thermal stability, as the idle current is kept independent of the temperature of the output transistors. A substantial 200VA toroidal transformer, followed by 4x15000uF reservoir capacity (60000uF in total), helps the amp to maintain firm control of the music and enabling excellent dynamic range.

Simple Preamp Circuitry: Much effort has gone into the physical layout of the 6000A's circuitry, protecting the sensitive preamp section from noise interference. The preamp section is kept as simple as possible to maintain signal purity, with line input signals passing to a precision analog volume stage. The volume range is from -78dB to +8dB in steps of 2dB and 1dB (step resolution increases with volume position).

Operation Modes: Although the 6000A is an integrated amplifier, it can also function as a separate preamp or power amplifier.

  • Integrated Mode: In Integrated Mode, the preamplifier section and power amplifier are connected and both active. The unit's preouts are still operational in this mode, so a second power amplifier can be connected for bi-amplification or a powered subwoofer can be added to your speaker system.
  • Pre-Power Mode: In Pre-Power Mode, the preamplifier section is internally disconnected from the power amplifier. The 6000A can then be used as a stand alone power amplifier in an AV setup. This mode can also be used if additional signal processing is required; connecting the preouts to an external signal processor and then take the output from the processor to the 6000A's Power Amp Input.
  • Pre Mode: In Pre Mode, all signals to and from the power amplifier of the 6000A are disconnected. In this mode the 6000A functions only as a stand-alone preamplifier, so it can be connected to a stereo power amplifier or two mono-block amplifiers.

High-Quality DAC w/ Filters: The Audiolab 6000A's digital circuitry delivers the level of quality one might expect of a high-performance standalone DAC. The 6000A utilizes an ES9018 Sabre32 Reference chip DAC to perform D/A conversion, featuring ESS Technology's 32-bit HyperStream architecture and Time Domain Jitter Eliminator to deliver ultra-low noise and high dynamic range. The DAC in the 6000A has a choice of 3 digital filters.

  • Fast: Standard flat response with fast frequency roll off above Fs/2 (half the sampling frequency).
  • Slow: Starts rolling off at a lower frequency than the Fast filter, but has a more gentle rate of attenuation.
  • Phase: Has a gentle attenuation slop similar to the Slow filter, but with minimum phase characteristics. It can be liked to an analog filter applied in the digital domain.

Bluetooth Audio Streaming w/ aptX: The Audiolab 6000A offers built-in Bluetooth with support for wireless audio streaming (A2DP). You'll be able to wirelessly stream stored music, music apps, and other audio content on your Bluetooth-enabled smartphone, tablet, laptop or computer to the 6000A integrated amplifier. In addition to supporting Bluetooth's standard SBC code, the 6000A integrated amp also supports Qualcomm aptX for "CD-quality" (44.1kHz/16-bit) sound from compatible source devices - such as Android smartphones and tablets, as well a Mac computers and laptops. You can pair multiple Bluetooth source devices with the integrated amplifier, but only one device can be connected and used at a time.

  • There is an external Bluetooth antenna included in the box that must be connected on the back of the integrated amplifier to use Bluetooth.
  • The unit offers no Bluetooth control; you'll continue to control music playback from your Bluetooth source device.
  • The unit does not display Bluetooth information; you'll continue to use your Bluetooth source device for song/artist/album information.

Optical & Coaxial Digital Inputs: The Audiolab 6000A is outfitted with two optical (toslink) and two coaxial (RCA) digital inputs for connection of a CD player, Blu-ray, media streamer, and/or TV. The digital inputs supports 2ch PCM audio up to 24-bit/192kHz.

Note: The digital inputs do not support Dolby Digital, DTS, or other multichannel audio formats.

Analog Inputs: The Audiolab 6000A is equipped with a total of five analog stereo RCA inputs. There is a power amp input, three line-level inputs, and one phono (MM) input.

  • Power Amp Input: The Power Amp input bypasses the 6000A's preamp section and allows you to use the 6000A as only a power amp.
  • Line-Level Inputs: The three line-level RCA input allow you to connect up to three analog audio source devices - such as a CD player, tape deck, and/or network audio player.
  • Phono (MM) Input: The phono (MM) input lets you directly connect a turntable with a moving magnet cartridge without an external phono preamp.

Binding Post Speaker Terminals: The Audiolab 6000A is outfitted with a set of binding post terminals that will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana plugs (single or dual). You can connect a pair of 8 ohm or 4 ohm loudspeakers.

Stereo RCA Preouts: The stereo RCA preouts can be used to connect an external power amplifier, powered subwoofer, or signal processor. The stereo RCA preouts are full-range.

Dedicated Headphone Amp: The Audiolab 6000A features a dedicated headphone amp and is outfitted with a front-panel 1/4" headphone jack on the front-panel. When a set of headphones is connected the audio from the integrated amplifier's loudspeaker terminals is turned off. The dedicated headphone amp can support headphones with an impedance of 20 to 600 ohm.

OLED Screen: The front-panel OLED screen indicates source, volume, and menu information. The OLED screen does not support song/artist/album information.

IR Remote: The included IR remote control provides wireless operation of the A6000A integrated amplifier, as well as other Audiolab components - such as CD transports and network audio streamers (sold separately).

Note: No batteries are included for the remote. The remote takes two "AAA" batteries.

USB Update: The rear-panel USB port can only be used for service and firmware update purposes.

Note: The USB port does not support any type of media playback or charging.

12V Trigger In/Out: The 6000A features a 12V trigger output and 12V trigger input. Each input consists of a 3.5mm minijack. The 12V trigger output can be used to control and synchronize the Power On/Off of another component with a 12V trigger input with the Audiolabs 6000A. The 12V trigger input can be used to control and synchronize the Power On/Off of the 6000A integrated amplifier with another component that features a 12V trigger output.

Auto Standby: The 6000A integrated amplifier will automatically enter standby mode after 20 minutes or 1 hour of no audio signal and control inactivity.

Detachable AC Power Cord: The Audiolab 6000A comes with a detachable 6.5' IEC 2-prong AC power cord.

can you hardwire a iphone thru the aux ?
john  Oct 18, 2023

Greetings John. Thank you for your question. If the phone has a headphone output, it would be 3.5mm. Then with a 3.5mm to RCA conversion cable you would run that into the Audiolab's RCA input in the back.
hogan  Oct 18, 2023 (Staff)
bass. How do you control the bass/treble (remote control)? (can you)? Thanks
stephen  Oct 08, 2023
1 answer
Bass and Treble controls are not adjustable on the Audiolab 6000A, Stevie. You do have a selectable DAC filter with three modes than can adjust your digital sources to your liking. If you prefer to adjust your EQ with a front panel control, consider the LEAK Stereo 130 in the link below as it has a wonderful sound quality and front panel EQ knobs.

Can the "power in" inputs be used as HT bypass?
noel  Jul 25, 2021
1 answer
The preamp inputs labeled Power are the ones used when this is in the home theater bypass mode or what they call the Pre-Power Mode.
jason  Jul 31, 2021 (Staff)
Is there any way to connect a powered sub-woofer?
frederick j.  May 25, 2021
1 answer
The preamp outputs can work with a powered subwoofer that has a low pass filter built in. We have advisors that can be reached by calling 1-800-324-9695 who can help recommend a powered subwoofer to use with it.
jason  Jun 08, 2021 (Staff)
In Crutchfield's search function, this amp is flagged as having a "Pre-Out / Main-In Loop". Is this accurate? Looking at the amp's back panel, I see a pre-amp out, but no main-in loop.
tim  Jan 02, 2023
1 answer
It is correct that this offers a pre-out/main-in loop. The "Pre-out" can be connected to an outboard signal processor. The output of the signal processor can then be connected to the power amp input (labeled "Power" on the back of the unit).
zachary  Jan 02, 2023 (Staff)
can i play my iphone thru the aux input on the audiolab 6000a?
john  Nov 17, 2022
1 answer
Yes. If your iPhone is 7 or newer, you'll need a Lightning to 3.5mm adapter as well as a 3.5mm to RCA cable. Our advisors are happy to help with picking these items. Feel free to reach out via online chat or phone at 1-800-324-9695.

6000A vs 6000A Play? Is wifi and Playfi the only difference between these two amps?
dennis  May 31, 2022
1 answer
That is correct. The 6000A Play is the same amplifier with the addition of Wi-Fi music streaming through DTS Play-Fi.
zachary  Jun 01, 2022 (Staff)
Does the 12v trigger input switch both the power and the source to a designated input?
nh1234  Dec 26, 2021
1 answer
I believe the trigger cable only affects power on /off. You can control the 6000a and the 6000CDT with one remote. You can switch inputs via the remote as well.
steve  Dec 28, 2021
Pardon my ignorance. I bought some banana plug cables but they dont fit. They only go half way. Any special banana plugs for the Audiolab? Thank you.
dennis  Oct 20, 2021
2 answers
I imagine you have this figured out by now, but for anyone else -- I was totally befuddled as to how in the world the banana plugs could fit until I searched YouTube and found this video showing how to insert them sideways through the hole in the post, as you would insert bare wire, and then tighten down. The YouTuber goes by Vintage Stereo and the title is "How to connect speaker cables to amplifier with banana plugs."
barbara  Jan 06, 2022
I don???t recall having to buy special banana plugs for my Audiolab 6000A. I use QED speaker cables and they work great. Suggest you return and try another set.

AC, 110-120V, 50-60Hz, 330W
marco  Jun 23, 2021
It is not and. The gear we sell is meant for use within the U.S. and will work on our 120V power grid.

Does it have option to change bass/ treble?
siddharth  Dec 02, 2020

robert  Dec 11, 2020
6000A does not have the option of tone controls for bass/treble.
camilo  Dec 11, 2020
It does not. It sounds amazing just the way it is but I understand that with some speakers you might want to change bass/treble settings.
