Our take on the AudioSource AD5012

One of the most important steps of planning your multi-room music system is choosing the right amplification. AudioSource's AD5012 is a great option for large homes. It's a high-current, multi-zone amp that powers up to six pairs of speakers simultaneously. It's flexible too. Play the same source through all six zones, or have a different source play in each of your rooms.

Amplify your whole-house music system

One of the most important steps of planning your multi-room music system is choosing the right amplification. AudioSource's AD5012 is a great option for large homes. It's a high-current, multi-zone amp that powers up to six pairs of speakers simultaneously. It's flexible too. Play the same source through all six zones, or have a different source play in each of your rooms.

Drive your speakers with authority

AudioSource equipped the '5012 with plenty of horsepower for your speakers. It delivers 50 watts per channel into eight ohms, and a robust 75 watts per channel into four ohms. Need even more juice to drive your heavy-duty outdoor or floor-standing speakers? Bridge two channels together and get a mighty 125 watts per channel into eight ohms.

Versatile inputs...

The AD5012 offers two pairs of RCA inputs, as well as one optical digital input. These are handy for playing multiple sources in your various listening rooms at the same time.

Say you have a Sonos CONNECT hooked up to input 1 and you're listening to Paul Simon's Graceland on Spotify®. You can have one, two, or even all six zones play Graceland. Let's say you also have a CD player hooked up to input 2. Four zones can jam to Paul Simon, while the other two play an Eagles CD. 

Each zone also has a dedicated pair of RCA inputs for playing a "local" source in that room only.

...and outputs

 Want to expand your multi-room system? Use the RCA outputs to feed audio signals to an additional amp of your choice.

Multiple power-on options

The '5012 can be turned on manually, or automatically when it detects a source. It's also 12-volt trigger compatible, so you can have it turn on when another piece of equipment is fired up.

Precise volume control for each zone

Each zone of the AD5012 has individual volume control for the left and right channels, giving you precise control over your system. If you have a big room that needs more volume to get to your preferred listening level, you won't blast the other zones when you turn up your preamp. Rear-mounted bass and treble controls provide tone adjustments.

Awesome Audiosource AD 512

J from Austin, TX on 10/8/2018

Crutchfield Customer Review (What's this?)

Crutchfield staff recommended this amp (x2) to drive a pre wired whole house audio system(22 speakers). The assisted with a few set-up questions. Amp is powerful and drives Revel ceiling speakers with awesome sound. Paired with Sonos connect units (×6) for zoned streaming and listening. Overall great purchase and customer service.

Pros: Power, configuration of zones and BUS options. Sounds great and reasonably priced.

Cons: Rack mounting, unit is very heavy

Total Lack of Operating Instructions

Crutchfield Customer Review (What's this?)

I bought an AudioSource AD5012 to channel music from our family room AVR to existing Russound controlled ceiling speakers in 3 other rooms. This $999.99 unit comes with just a 4 page manual that explains almost nothing. I plugged the AVR into the new amp's "Sub 1" inputs with output to the existing 4 x 18 ga wiring to the house's 3 zones. The AD5012's 7 blue lights (master; 6 zones) all turned on, indicating no shorts. No sound came from the speakers. I went back & forth from amp to Russound controls, trying to understand the problem. The AD5012 user manual is useless, & the AudioSource website offers no tech support. I called Crutchfield. Their tech told me I needed to turn the "channel gain controls" on the AD5012 to max, to allow the Russound controls in the rooms to operate properly. I turned up the AD5012's gain controls on, & the ceiling speakers in the other rooms worked great. I thanked the Crutchfield tech for explaining what the manufacturer didn't describe. Everything fixed...until... The next day, 1 of the zones had high static & the AD5012's "Zone 1" blue light blinked red. I called Crutchfield. The tech told me to switch zone 1 & zone 2 wiring, to learn whether the short was the AD5012 or the Russound. I did this & powered up. The master switch on the AD5012 turned red. More calls to Crutchfield. The AD5012 went back to Crutchfield. A replacement AD5012 is on its way. Lots of hours spent so far. Crutchfield was great help.

Pros: Yet to find out if AD5012 works. Crutchfield tech support has been great.

Cons: Four page manual completely lacks instruction. AudioSource website doesn't provide tech support.

A great value for a solid amplifier.

Crutchfield Customer Review (What's this?)

I purchased the AD5012 to power 4 in ceiling speakers in my kitchen and 2 patio speakers. I really liked the bridging option available on this amp. The unit is very versatile with 2 bus inputs and line inputs for each of the 12 channels. The remote allows the option of controlling the volume on each of the 2 bus inputs. I bought a Sonos connect to control the volume and input selection for the kitchen speakers and plan to do the same for the patio speakers to allow for more control over each of these zones. So far I am quite impressed. The unit has plenty of power and sounds good. It also seems to run pretty cool.

Pros: good control versatile good value

Cons: pretty heavy all controls are on the back of the unit

Amazing piece of equipment.

Crutchfield Customer Review (What's this?)

This thing is AWESOME!! i wasnt sure if it was going to work with my stereo- but it does. It's powering my speakers throughout my house. It has an awesome feature that it really doesnt tell you in the initial specs online- It's able to sense a signal from your stereo- and it turns on and off by itself- so you never have to touch it again. Plenty of power- - awesome product!

AudioSource AD Series: AudioSource AD series digital amplifiers are designed for home and commercial audio distribution systems where high quality sound, flexibility, and reliability are essential. The AD series offers high efficiency and exclusive features that will make their installation and use easy and convenient.

12-Channel Power Amplifier: The AudioSource AD5012 is a 12-channel amplifier that is designed for distributed audio applications. The amplifier can be configured for Stereo (4-ohm minimum) or Bridged (8-ohm minimum) output.

  • Stereo (8-ohm): 50 watts x 12 channel @ 20-20kHz with <0.2 THD+N
  • Stereo (4-ohm): 75 watts x 12 channel @ 20-20kHz with <0.2 THD+N
  • Bridged Mono (8-ohm): 125 watts x 6 channel @ 1kHz with <0.2 THD+N

6 Zones: The AD5012 can distribute audio to 6 Zones. You can configure the amplifier to play the same source input (Bus 1/Bus 2) in each Zone, group source inputs (Bus 1/Bus 2) in specific Zones, or have different sources (Line In 1-12) playing in each Zone. Each Zone can consist of one pair of stereo speaker, two speakers in mono, or one Bridged-mono speaker. Each Zone also has independent level control.

Bus Line Inputs & Outputs: The AD5012 has two "common" or Bus inputs that receive audio signals from standard line-level audio sources and sends them to any or all channels and zone. The two pair of Bus line outputs are direct feed-through to allow the Bus inputs to be fed to other amplifiers.

  • Bus Level Controls: Each Bus has its own independent level adjustment. This allows the output level of each Bus to be adjusted to make up for different source levels, or to group two different source's volume levels. The Bus Level Control can be operated from the rear-panel or remote control in 1dB increments.
  • Bus Bass & Treble Controls: Bass (100Hz) & Treble (10kHz) can be adjusted (from -12 to +12B) independently for Bus 1 and Bus 2.

Optical Digital Input: The AudioSource AD5012 also features an optical (toslink) digital input that is assigned to Bus 1. This digital input only support 2ch PCM (not compatible with Dolby Digital or DTS).

Individual Channel Input: In addition to the Bus line inputs & Optical digital input, the AD5012 offers a dedicated input for each of the twelve output channels, so you can have a discrete source playing through each connected speaker.

Phoenix-Style Speaker Outputs: The AD5012 uses high-quality Phoenix-style connectors for each speaker output (1-12). The Phoenix-style connectors can accept 14-18 gauge speaker wire. There are two sets of Phoenix-style connectors in each Zone (1-6), so you can connect two speakers in stereo, two speakers in mono, or one speaker in Bridged-mono in each Zone.

  • Source Selection: Each output channel (1-12) is capable of delivering source audio from on of 3 inputs - Bus 1, Bus 2, or Line In. You can choose to play the same source or different sources from each output channel.
  • Gain Control: Each output channel (1-12) has its own independent level adjustment. This allows the output level of each speaker to be perfectly matched to its area. It can also be used to limit the maximum audio level in a certain area.

IR Remote: The included IR remote provides wireless operation of the power amplifier. Remote functions consists of Power On/Off, Bus 1 Volume Up/Down, Bus 2 Volume Up/Down, and Mute.

Trigger Input/Output: The AD5012 is outfitted with a trigger input and output, each consisting of a 3.5mm minijack terminal. The 3.5mm trigger input will accept a 3-30V AC/DC output from another electronic component device to turn the amplifier On from Standby mode. The A508 also provides a 3.5mm trigger output (12V/500mA) to turn on and off another electronic component device.

Detachable AC Power Cord: The AD5012 comes with a detachable 6' AC power cord which will need to be plugged into an AC wall outlet, surge protector, or power conditioner.

Mounting Options: The AudioSource AD5012 power amplifier features four heav-duty feet and can simply be placed on top of a flat surface; like a table-top, shelf, or stand. You can also remove the four feet and rack-mount the amplifier using the included rack-mount ears and screws.
