Description

Dayton Audio's SA1000 mono subwoofer amplifier provides nearly a kilowatt of clean, solid power to your home theater or music playback system. The amp's convenient freestanding or rack-mountable configurations make it an ideal partner for high-performance subwoofer speaker systems. Key Features Dayton Audio's SA1000 mono subwoofer amplifier provides nearly a kilowatt of clean, solid power to your home theater or music playback system. The amp's convenient freestanding or rack-mountable configurations make it an ideal partner for high-performance subwoofer speaker systems. Based on a state-of-the-art Class-G circuit topology the SA1000 combines the proven high power, high fidelity characteristics of a Class-AB amplifier with a patented tracking down converter power supply to achieve an operating efficiency up to 86%. You get the efficiency of a Class-D amplifier without compromising audio quality and reliability. The Class-AB output stage provides the clean and low-distortion sound that audiophiles demand, without any of the instability problems that plague other high-efficiency amplifier designs. The Dayton Audio SA1000 is a freestanding, high-power subwoofer amplifier designed for the DIYer, installer, and systems integrator. This unique monaural audio device delivers the raw power of a pro-sound amp, but with the features and flexibility of a dedicated subwoofer amplifier. It can be configured for stacking with other audio components, and includes removable ears for mounting in standard audio racks (2RU). The SA1000's patented tracking down-converter power supply ensures headroom for instantaneous power needs and the amp stays cool, thanks to its high-efficiency design. Key Specs: Class-G Innovation SA1000 subwoofer amplifier uses a patented Class-G topology that continuously tracks the input signal to modulate, or control, the voltage available to the output stage. This "tracking" capability delivers the exact amount of power based on demand instead of constantly keeping it in reserve, so the output stage only draws the amount of power that is required at any given time. Less energy is wasted as heat, and more power is available for the subwoofer driver. In addition, advanced soft clip circuitry provides cleaner transient peaks while protecting your driver from over-excursion. With its enhanced thermal management, the SPA1000 is an upgrade over previous models—making it a nearly bulletproof amplifier choice for today's demanding HT audio and music playback applications. Feature Packed The amp's switchable subsonic filter removes subsonic information from the signal, which tightens the low end response of some subwoofer systems. A switchable bass boost enhances LF performance while leaving the parametric EQ function available to address room modes, like cutting an excessively loud room resonance. The high-pass outputs provide a user the option to feed the signal back into their other audio components or a distributed audio system. Manual, automatic on/off or triggered 12V input modes allow easy integration into automated systems. The stealthy pop-out knobs on the front panel make adjustments easy, while minimizing the risk of accidental disturbance. The SA1000's subdued brushed black aluminum faceplate allows the amp to blend cosmetically with any type of audio gear. Accommodates RCA line-level inputs, includes insulated binding posts for the speaker outputs, and accepts a 12V trigger via a 3.5 mm mini-jack.

    • Nice amp
Sound is so subjective. If we all heard the same then there would only be a handful of speakers for sale. I am somewhere between and every day person and an audiophile, probably more like and audio enthusiast. I enjoy crystal clarity of sound and imaging. I am a 2 speaker stereo person, surround sound is fine, but I would rather have 2 great speakers instead of 6 or 8 ‘average’ surround sound speakers. I had a plate amp on the back of a subwoofer I built. It was an NHT1259 in a sealed box. I was powered by a 250 watt plate amp built in to the sub enclosure. I had it for years and liked it. After a night of running this plate amp at very high volume it got too hot and burned some components. One of the things I never liked about the plate amp was that the controls were on the back of the sub. It was a pain to adjust while listening and had to go by memory of which knob did what function. I got this SA1000 amp to replace it and am very happy. The amp is a very heavy unit, as it has a nice heavy transformer (always a big plus). I enjoy the front mounted controls as I can see what knob I am adjusting (as opposed to a plate amp on the back of a subwoofer). I ran the amp all night and it did not get hot to the touch. It did get slightly warm. I has more punch than my older 250 watt plate amp and it is more clean sounding. My only complaints: The soft clip circuitry is useless as when it clips it is just as bad as any clipping amp and the blue power button, it is too bright. The amp does not have any audible hum when in use. ... show more

    • Amazing, Heavy Duty, quality unquestionable
Absolutely amazing. Use to power two buttKicker LFE for DCS World . Forget about the butkicker amp. Garbage compared to this monster. Heavy as heck but . Heavy = quality. Outstanding must have if your powering high end tactile subs

    • Great sounding, very rugged and powerful and flexible sub amp, but has turn on thump
This thing is built like a tank and provides very high fidelity bottom end, and a lot of power. The parametric EQ is an excellent feature, as is the multiple turn-on options, with either auto-sense, 12v trigger, or manual. It would be a solid 5 stars if it weren't for that nasty power on thump. They really should've designed a delay relay or another means to prevent this, especially at this price point. But I'm keeping it for the fidelity, The Dayton Class AB/Class G Sub Amps really sound excellent. I have some of their plate amps too. ... show more

    • Clean sound, big power
This powers my Stereo Integrity SQL-15 D4 wired to 8 ohm. The sound is incredible. Plays down to around 10hz and hits that chest thump range throughout my house.

    • The sound is very clean and blends in great with my 200w mono blocks
This is what my system needed. With my two home made sub enclosures. Now they get all the power to drive them. The sound is very clean and blends in great with my 200w mono blocks. Set at 80hz to 100hz with a little over half gain was it and done. It's good they give so ways to control the output. Well, for those who really need it. Otherwise keeping it simple works the best for most. This amp is not complicated unless your trying to do to much with it. The "less is more" formula works just fine. Look I'm listening to it right now and it sounds great with very little set up. The only thing to complain about is the LED light could of had a dimmer installed. But a easy fix was with a small drop of nail polish from wife. Now it's not so bright anymore. Overall I am real happy and believe it to be a very good amp. ... show more

    • Great value
I use this amplifier to drive an 18 inch Cervin Vega XL 18S in an infinite baffle mounting. The sound is great and the power is plenty. The adjustments for frequency, phase and EQ work well. However, I would prefer larger knobs, especially for the gain potentiometer.

    • Does Not Produce Rated Power
The Good: Adjustable crossover and the parametric EQ functions The Bad: NOT 1000W RMS I have two 12" Kicker L7 subs with dual 2ohm voice coils in a custom 4.2 cubic foot enclosure (2.1 per sub) for home use. I was running the subs at 4ohms per channel on an old Pioneer 2X50RMS amp for a total of 100W. Sounded fine, but I had to take it easy on the amp as it ran hot due to being wired at 4ohms instead of the rated 8ohms. I figured it was time for an upgrade, so I purchased the Dayton Audio SA1000. 1000 watts should be a big upgrade right? Wrong!!! When I first hooked it up I wired all four coils in series for a total of 8 ohms. In this configuration the SA1000 should put out about 500W RMS. I turned it on, turned it up... and it was pathetic. Sounded like maybe 50 watts. I thought maybe I had flipped the polarity of a coil or something... nope. Everything was connected correctly. Turn everything to the right and watch the clip indicator stay lit most of the time... no power, no ommph, no boom. The 12's connected to the surround sound receiver were louder than the dedicated subs. So I rewired the subs using only one coil per sub in series for a total of 4 ohms. The amp should produce 1000 wats RMS in this configuration, more power than the two coils combined would be (275 watts RMS per coil). That would be a lot of power, and in theory it should be twice as loud as the old pioneer. But this amp doesn't make 1000 watts. I spent a few hours switching back and forth between the two amps. Playing the same tracks, test tones, and frequency sweeps. The clipping indicator on the SA1000 starts flashing at about the same listening volume as the Pioneer would start to audibly clip. The SA1000 starts audibly clipping at just a tad over where the Pioneer would play before clipping. So, maybe 300 watts RMS??? Disappointing. I have not hooked up the oscilloscope or clamped the amp to see what kind of power it is really making. But there is no way it is making 1000Watts. I should have gone with some low line pro audio equipment rated in the 1500-2000W range. Would have got more power per dollar. I do like the adjustable crossover and the parametric EQ functions. Allows me to put more of the available power on lower frequencies. The amp runs cool, even with the clipping indicator blinking with the beat the amp never gets hot. But the rated power is just not there. ... show more
