Our take on the AudioSource AD1002

The AudioSource AD1002 stereo power amp makes a great choice for powering speakers in your multi-room sound system. This versatile amp's dual line-level inputs let you enjoy sound from one main music source plus and additional "local" audio source, switching automatically between the two.

Multi-room audio power

The AudioSource AD1002 stereo power amp makes a great choice for powering speakers in your multi-room sound system. This versatile amp's dual line-level inputs let you enjoy sound from one main music source plus and additional "local" audio source, switching automatically between the two.

Say you have a network audio player, such as a Sonos CONNECT as your primary source feeding the AD1002's main input. Any time you fire up the Sonos player, your AD1002 turns itself on and sends the music to your speakers. Then, if you connect another music source like a CD player or portable music player to the secondary local "Interrupt" input, the amp will switch to that source whenever it senses an incoming music signal. When a CD stops playing, the AD1002 will automatically switch back to the Sonos. There's no need to manually switch inputs.

Bridged mono mode for more power

The AD1002 can power one or two pairs of speakers. Use it in stereo mode, or add a second amp and bridge them for a more powerful dual-mono setup. This amp's low-profile design makes it easy to place in a room where space is tight. Place it on a shelf or stand, or rack mount one or multiple units with the included hardware.

With loop output and 12-volt trigger input and output, the AD1002 provides the power and flexibility to support a wide range of multi-room system configurations.

Product Highlights:

  • 50 watts x 2 into 8 ohms or 75 watts into 4 ohms
  • 160 watts when bridged into a single 8-ohm load
  • high-efficiency switching amplifier design
  • front-panel volume and balance controls
  • A/B speaker switching
  • rear-panel bass and treble controls (± 12dB @ 100 Hz and 10,000 Hz)

Crutchfield Customer Review (What's this?)

Now I bought four of these amplifiers and are running one speaker on each amplifier bridged mode so far I've been pretty happy it sounds awesome but on the small end . all 4 amplifiers start to warm up you will get a small hump at high volume on mute. But not noticeable when you are listening to music or watching movies in theater mode .now I've only had them for a short time . so far pretty happy will return to do another review in the future. I'll let you know if I still continue to be happy

Pros: If you've got two large front speakers and two large rear speakers and still have your full surround sound and you hook your surround sound to your stereo and run amps off the stereo into your 4 main speakers this made it so I did not need to run a sub all four large speakers go low enough in hertz that you do not need to run the sub this is on the basis that you have 4 large speakers and definitely a lot of power for little money

Cons: Once again I was mentioning the small hung that you get when the amps warm up at a higher volume on mute. that's when you will hear this hump otherwise listening to music or theater mode you will not notice it. Especially at low volume two medium volume you will not hear it three quarter volume you will start to hear the hum but now I preset the amps volume at one setting and the main volume on my stereo receiver interface controls the main volume. Remember you will only hear this on mute

Crutchfield Customer Review (What's this?)

This was the perfect choice for me. I was using a very "warm" amp in a cabinet to drive music from Alexa and wanted the amp to shut down when Alexa was quiet. I used a smart plug but my old amp powered up in "standby", not "on". The AD1002 is a perfect solution (almost). It shuts down when Alexa is silent and automatically comes on when Alexa wants to talk or play music. Why "almost" perfect? When the AD1002 powers up from standby, there is a slight delay and Alexa loses a couple of her words while waking up the AD1002, but hardly noticeable. Another huge plus is how cool The AD1002 runs, even when working. This unit has plenty of power and a great sound for driving my ceiling speakers.



Good Bang for the Bucks

Cheap power, pretty clean for digital, Bass n Treble adjust on back nice feature since I can't use my Yamaha R-S700 tone adjustments in a Zone 2 setup. Two amps Bridged Mono 160 WattsGood Bang for the driving an inexpensive pair of BIC RtR Eviction 15 speakers in living room and Bose enviromental at pool side. Would've gave a 5 if Bass n Treble was on front panel. Great setup with power for parties, but I favor my Jolida tube, PAS 3 and Klipsh referance in Den when not having parties.

Pros: inexpensive, Great power, Bass n Treble feature very useful.

Cons: Really none.

The AD*002 line (AD1002, AD2002, AD3002) all appear to be digital amplifiers. That is the difference of this model from the AMP100VS. You can also tell because this unit is physically thinner and lighter than the AMP100VS. [ Davin  Feb 25, 2018 ]

I'm afraid AudioSource does not specify the AD1002's amplifier class. However they describe this model as a "high-efficiency switching amplifier design"; which indicates a closer similarity to class D than class A, B or AB. For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Hope that helps! [ Larry  Aug 22, 2017 ]  Staff
I'm sorry, I don't have that information so I can't answer your question. [ John  Aug 22, 2017 ]
its has switches that provide a path to (A) and a path to (B) therefore A and B [ Anthony  Aug 21, 2017 ]
I can't answer your Bose or Chromecast question. The case alone is 6" deep. From the tip of the binding posts to the tip of the knobs is a little less than 7.75". [ Brent  Apr 24, 2017 ]
Hey Paul, yes, AS-AD1002 works with any audio. The biggest question would be what will your source be ?? I would have to check mine at home to be sure of "inclusive" button depth. I use the Main input and 12V trigger coming from my receiver and output to a 2 channel speakers in stereo. [ Christopher  Apr 24, 2017 ]
