Product Details

Dayton Audio DA30 2 x 15W Class D Bridgeable Mini Amplifier

Dayton Audio's DA30 is the ideal amplifier for commercial audio installations such as classrooms or offices, where a small, low wattage power amp is required. This palm-sized Class D amplifier sits inconspicuously on a desktop, and can also be installed on walls or under cabinets by using the included brackets. Perfect for powering ancillary zones in large setups, or mounted on or near a video projector!

The DA30 delivers 15 watts per channel in stereo mode and 30 watts when bridged mono. Two stereo audio inputs increase versatility: dual RCA or a single 3.5 mm TRS jack. Separate treble and bass controls allow the sound to be tailored to the room. The DA30's auto-on feature increases energy efficiency. An all-metal chassis and the selection of high-spec internal components ensure reliable operation and a long service life.

Specifications: • Power output: 2 x 15W RMS into 4 ohms, 1 x 30W into 8 ohms • Efficiency: 92% • Total harmonic distortion: 0.015% 20-20,000 Hz • Bass/treble turnover: 100 Hz/10,000 Hz • Input impedance: 100k ohms • Auto-on sensitivity: <0.8V • Stand-by current consumption: 0.6 mA • Power supply: 24 VDC, 2000 mA • Dimensions (H x W x D): 1-5/8" x 4-7/16" x 5-1/2".

Dayton Audio DA30 2 x 15W Class D Bridgeable Mini Amplifier
Dayton Audio DA30 2 x 15W Class D Bridgeable Mini Amplifier is rated 4.6 out of 5 by 10.
Rated 4 out of 5 by from Nice little ampI'm using this to drive a couple of speakers for my desktop PC and as a makeshift speakerphone amp. Works pretty well for what I need. Wish the LEDs were a little less bright and that both the RCA and 3.5mm could be used at the same time. If the 3.5mm wire is plugged in the RCA jacks are disabled. Other than that all is well. Time will tell on durability.

Rated 4 out of 5 by from Switch from stereo to bridgeSwitch from stereo to mono bridge was installed backwards. When on stereo it's mono and bridge it's stereo.

Rated 4 out of 5 by from Perfect for the priceWe used this on a package we sold. It is a nice small unit yet powerful enough to run 2 speakers in a video conference room. The upper end of volume does seem to distort. maybe the power supply is not large enough.But in our case it did fine.

Rated 5 out of 5 by from Perfect ReplacementI bult a Heathkit AA-14 back in the 1960s. When the left channel went out this summer I thought it was time for a replacement, after 40-some years - imagine that! Saw Dayton Audio's DA-30 and was a bit skeptical - the speakers are in the family room and serve all sorts of decks and the TV. But skeptical I am no more! I know it's not handy to access the bass, treble and balance controls, but it's set so it sounds excellent and I shouldn't have to tweak these with the screwdriver. It runs the old Electro-Voice inefficient speakers with plenty of bass, good treble and the power response is smooth and could blow you out of the family room. Thanks for such a great product.

Rated 5 out of 5 by from Dyaton Audio DA 30 AmplifierUsed it to power a subwoofer in my motorhome, work great!

Rated 5 out of 5 by from Solid amp, great valueI wanted a small amp to use for an outdoor speaker system. I have two Polk outdoor speakers and a subwoofer that is not powered. I had a very tiny 2 watt amp that wasn't quite beefy enough and clipped pretty easily, so I purchased the DA30 to replace it. Very clean sound, and is perfect for what I needed. Not a lot of features and inputs, but I don't really need much. Tone controls are recessed and need changing with a small screwdriver, but that isn't a big deal as I run it flat and can tweak levels with my tablet if need be. So far so good.

Dayton Audio DA30 2 x 15W Class D Bridgeable Mini Amplifier

Is the power rating RMS or peak? Is the THD rating at rated output? THD rating at 1000Hz or 20-20K?

Asked by: Tin Ears
How refreshing to see an amplifier that is conservatively rated!You can estimate an amplifier's power simply by knowing its supply voltage.Non-bridged: Veff = Vsupply / 3Bridged: Veff = 2 * Vsupply / 3Prms = Veff * Veff / R(The Veff constant is based on Sqrt(2)/2 = .35, but in practice, there are always some voltage drops in the output transistors, so 1/3 is a better approximation.)For this amp, Vsupply = 24V so:Non-bridged: Veff = 24V / 3 = 8V8 ohms: 8V * 8V / 8 ohms = 8W4 ohms: 8V * 8V / 4 ohms = 16WBridged: Veff = 2 * 24V / 3 = 16V8 ohms: 16V * 16V / 8 ohms = 32W(4 ohms: 16V * 16V / 4 ohms = 64W)(This amp is not rated for bridged operation into a 4 ohm load, so the bridged 4 ohm case does not apply. In bridged operation, each channel "sees" half of the load impedance, so a 4 ohm speaker would look like 2 ohms to each channel, overloading this amp.)The numbers calculated above are just a bit higher than the actual ratings, because the Veff calculation is just an approximation without knowledge of fine circuit details. If you see an amp that is rated significantly higher than the above calculation, you can be fairly certain that they are playing games with the specs.To get a complete picture of an amp's power capability, you also need to know how much current it can supply, and for how long, and how much heat it can dissipate. However, for many music-related purposes, the voltage-base calculation above gives a useful upper bound.

Powering 4 speakers

I'm thinking about doing an in wall setup in my garage powered by this amp. Question is, will it be okay to run 2 sets of in walls with final load of 4 ohms to each channel of this amp?
Asked by: paragv
From a purely technical point of view, yes. This amp is rated to drive a 4 ohm/channel load. The only question would be what you expect to get from this setup.At 15 watts per channel into 4 ohms, this is not exactly a powerhouse. Assuming 2-8 ohm speakers/ch for a 4 ohm load, you'll get only 7 1/2 watts per unit; 7 1/2 w MAX. That's not much. And if you want it loud, that's not nearly enough. You need to supply more information about your expectations and what you'll be driving with it.

Could you describe the main amp(s) IC? Efficiency and THD resemble Class T.

Asked by: TechTJe
This amp uses class D topology with a TDA8932T at its heart.

Is the tone control accomplished in the analog domain?

Looking for detail on the EQ functions. Also, is the amplifier wired with one channel flipped in polarity to avoid "pumping"?
Asked by: chmedly
Take a look at the price, the size and the intended purpose, then ask your questions again. As to eq, I'm thinking linear taper potentiometer.

Can this amp be used strictly in mono mode for a single monitor speaker?

I would like to upgrade the stage monitor speaker system in our church. The features of the Dayton DA-30 stereo amp seem suited for our needs (tone control and price). However, our available audio input signal is mono, not stereo. Can this amp. be connected in mono mode? If so, how is this accomplished and what parts are required?
Asked by: sdlony
You would have to adapt your signal cable to a 3.5mm male plug. Use a male plug, NEVER use a "Y" adapter on inputs; only outputs. BAD THINGS CAN HAPPEN IF YOU GET THIS WRONG.Having said that, I would question whether or not this is a good choice for your purpose. In a small, traditional church needing only a little vocal help, maybe. In anything else, ie. larger, needing instrument monitoring, Charismatic or other church engaging in lots of praise music, choral, instrumental presentations, 30 watts won't do anything but distort. In those applications I would recomend buying a power amp to match the rating of the monitor.This would have worked fine in the Presbyterian church in which I was raised, but they still don't have a pa. Too smallHope this helps.

Will this amp work and have usable output with 12VDC?

Asked by: Ajbastro
The specs call for a 24vdc power supply, so it's highly unlikely. Even if one could get any output from 12vdc, the probability of catastropic damage from under-powering should convince you not to try it.
