These amps made my in-ceiling speakers sound a LOT better than a bunch of cheap little amps I was using before. The only tricky part was wiring the speaker wires into their proprietary connectors and making sure there was no excess exposed wire sticking out (as the connectors for positive and negative are within millimeters of one another - which causes a lot of static if there's any exposed wire) as well as making sure that the wires for each channel were connected properly (they DO NOT wire up like normal amps, so pay very close attention to where the positive and negative wires need to go for each pair of speakers). But other than that I couldn't be happier with my purchase. I also have a Dayton Audio subwoofer amp and it has performed like a champ over the last several months. Highly recommended! Review: For then price a great amp for multi-room audio, couple of caveats - When I moved into my house four rooms and the outside were professionally wired for audio, but they didn’t leave the amp… for the next 10 years I settled for a single zone inexpensive 100watt amp and distribution switch since it wasn’t a priority. This sounded fine at low volume, but was ineffective for the outdoor speakers. I decided to up my game so I could have some decent tunes while in the pool. So far I’m very impressed with this amp. I have wall volume controls in each room, but the ability to control the max volume for each speaker has allowed me to insure my kids can’t crank the volume inside excessively loud ( I capped these are at 35%) and pump up the max to the outside speakers (gain is at ~75%). The setup is very easy and the instructions very clear. For the price I think this is a great choice. I almost splurged on the more expensive model with the built in AirPlay, but I appreciate the physical switches on this one. The auto turn on (trigger) and turn off work great. There is almost no lag when the audio source starts feeding signal. I’m using an AirPort Express using AirPlay, and that has a mini phono (stereo headphone) to RCA feeding it. Here are my CONS in order of importance (no show stoppers): In bridge mode, it does mix the channels to mono, but you can’t control the left and right speakers independently for the bridged channel/zone. Only the left gain is used and it controls the max volume for each speaker in the pair. I didn’t have this level of control before so it isn’t a show stopper, but since the one of the exterior speaker is close to a seating area and the other isn’t (pointing to the pool) independent control would have been nice. BTW, I used bridge for to power boost and because stereo didn’t make sense with the speakers outside. The gain control for each speaker is very small and is on the rear. It can make tweaking things more inconvenient. Also, it necessitates having some sort of volume control either at the speaker or at the audio source, because you won’t be using these to control volume day-to-day. The amp has a slight hum when running. This doesn’t bother me because the amp is mounted somewhere without people regularly near, but if you were in the same room it could be annoying. This isn’t really a con, but be aware this is fairly large and fairly heavy. If you are putting it on a shelf, make sure you have room for the speaker wires and the power connections. This probably adds another 1.5 inches to its depth, and I’d recommend at least 2 inches so you’re not squishing everything. ## Features - Stable Class-AB design delivers superior audiophile sound quality and performance - Independent and bus inputs enable unparalleled flexibility - Bridgeable channel outputs provide additional power when needed - Independent channel gain controls allow the output of each speaker to be perfectly matched - Multi-stage protection circuitry for reliability and easy troubleshooting of audio system ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003DKVZHQ | | Best Sellers Rank | #189,470 in Electronics ( See Top 100 in Electronics ) #412 in Audio/Video Receivers & Amplifiers #1,087 in Audio Component Amplifiers | | Brand Name | Dayton Audio | | Customer Reviews | 4.2 out of 5 stars 142 Reviews | | Item Dimensions | 16.7 x 14.25 x 4 inches | | Item Weight | 15.52 kg | | Item dimensions L x W x H | 16.7 x 14.25 x 4 inches | | Manufacturer | Dayton Audio | | Material Type | Metal, Plastic | | Maximum Output Power | 80 watts | | Maximum Supply Voltage | 230 volts_of_alternating_current | | Minimum Supply Voltage | 120 volts_of_alternating_current | | Model | MA1240A | | Mounting Type | Surface Mount | | Number of Channels | 12 | | Number of Items | 1 | | Output Power | 40 watts | | Package Type Name | Box | | Part Number | MA1240A | | Specification Met | FCC | | UPC | 844632081095 | | Unit Count | 1 Count | | Voltage | 12 volts | ## Product Details - **Item dimensions L x W x H:** 16.7 x 14.25 x 4 inches - **Manufacturer:** Dayton Audio - **Maximum Supply Voltage:** 230 Volts (AC) - **Minimum Supply Voltage:** 120 Volts (AC) - **Voltage:** 12 Volts ## Images ![Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - Image 1](https://m.media-amazon.com/images/I/51TNRA9rsgL.jpg) ![Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - Image 2](https://m.media-amazon.com/images/I/51W2xDySayL.jpg) ![Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - Image 3](https://m.media-amazon.com/images/I/41FwRQepG9L.jpg) ![Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - Image 4](https://m.media-amazon.com/images/I/71p6cVChCLL.jpg) ![Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - Image 5](https://m.media-amazon.com/images/I/61NGwkhw0tL.jpg) ## Questions & Answers **Q: can I select more than one zone at a time also do I need separate volume controls at each zone** A: This is actually one of two parts, think of this as the power for each zone. The zone and source audio controls should be run through separate multi audio controller. For a better understanding the latest is the Nuvo line by Legrand. build several houses and restaurants running amazing audio on this multi channel amp. Clients love it so far. Just watch out for the eco friendly auto shutoff. If there is no audio signal it shuts down goes red on the amps, It comes back on when audio signal is turned up/on and does take a 5-19 second warm up to bring sound up, then you get blue-lights and all is good. **Q: Can I connect another amplifier to this one to power one more room? I believe the term is daisy chaining.** A: I did not do it that way. Instead I used Sonos products with 3 of these amps to power about 40 speakers, two separate Pioneer amps, TV's, FM radio, laptop computer, and a Bose CD player. It worked out great for me. Before I bought the amps I contacted customer service at Dayton. They were really knowledgeable and helpful. I suggest doing that with any specific question. These are great amps and I highly recommend them. **Q: Will this drive 16 speakers @ 8 ohms? Forgive my ignorance but I am confused if 12 channels means 24 speakers (12 pairs) or just 12 speakers (6 pairs** A: 12 channels = 12 speakers. Two channels per zone, there are six zones. Don't let the 40 watts fool you, it is more than enough power for ceiling/wall speakers to get loud. **Q: can I power 5 different rooms each with its own volume controller?** A: Yes. However the position on the rear of the unit and their small size makes them better suited for initial trim and adjustments rather than constant altering. I controlled 6 rooms with mine and the volume was always handled from the smartphone that was AirPlaying to that room. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic amp for multi-room music setups! *by H***N on November 30, 2020* I bought two of these for my 12 zone / 24 speaker whole house audio system and I'm thrilled with the build quality (these things weigh 35+ pounds *each* and are built like small tanks!) as well as the sound quality.

I set up 6 zones downstairs that were pre-wired before the house was completed. I wired directly to the speakers, not using a volume control in each zone. I bought 12 Alexa Dots and 6 3.5mm to RCA converters. Then I attached 6 of the dots to the RCA inputs for each zone on the amp and put each of them on mute. I also placed a an Alexa dot in each zone. Then I named each dot carefully. The dot in the Kitchen is named "Kitchen Dot" and the dot in the closet for that zone is named "Kitchen Speakers" This allowed me to tell any dot, anywhere in the home, "Alexa, play music on the Kitchen Speakers" and the dot in the closet streams the music to the speakers. You can also tell Alexa to "Lower the volume on Kitchen Speakers", so I avoided having to install or purchase volume controls in each zone. I am going to buy another unit for the upstairs zones now. Alexa also has Groups, you you can group multiple Zones together and say "Alexa, play music Downstairs" and it streams to several zones. I also have a group I call "upstairs intercom" so, I can stream "Reveille" in the morning to get the kids to head downstairs for breakfast. Update: I added the second amp for the upstairs zones and everything is working as planned. I have 24 Alexa dots running the two amps and the kids love that they have control over every room in the house and what music is playing on the ceiling speakers. I made a few groups, Like "Master Bedroom" group, that plays in Master bath, office and bedroom, in Alexa to allow multiple zones to play the same music as well. Also made a "Main" group that plays on all the common area speakers. Update: Alexa now allows me to make a dot a member of more than one group, so the office is now part of "All Downstairs Speakers" group, but not part of the "Downstairs" group (which is just the common areas). ## Frequently Bought Together - Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier - WiiM Pro AirPlay 2 Receiver, Google Cast Audio, WiFi Multiroom Streamer, Compatible with Alexa, Siri and Google Assistant, Stream Hi-Res Audio from Spotify, Amazon Music, Tidal and More - WiiM Mini AirPlay 2 Wireless Audio Streamer, Multiroom Stereo, Preamplifier, Works with Alexa and Siri Voice Assistants, Stream Hi-Res Audio from Spotify, Amazon Music and More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/688286491-dayton-audio-ma1240a-multi-zone-12-channel-amplifier](https://www.desertcart.hk/products/688286491-dayton-audio-ma1240a-multi-zone-12-channel-amplifier) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-09-05*
