Can I connect the speaker outputs from my receiver to this amp, and if so will the volume change as the receiver changes?
A shopper
on Nov 10, 2017
BEST ANSWER: NO! You cannot connect this amplifiers inputs to your speaker outputs. You will damage this and your amp. Your receiver should have a line out. You will need to check with your receiver users manual to see if volume changes will effect the line out or how to make that happen.

Speaker outputs on your receiver are “speaker level” and amplified. If your receiver has “line level” RCA outputs, use those. If not, and you must use speaker level signal you’ll need a speaker to line level adapter to reduce the voltage level. I’ve had very good results using a PAC SNI-31 in several different applications.

Not a good idea. Speaker outputs are designed for an 8ohm load, very different from the input. Might kind of work but not well. You might have a line output or an output for a recorder on your receiver. That would work but may not have volume control.

Yes you can but the speaker out is already amplified so the signal will get clipped probably as you bump up the volume on this amp. This is meant for connecting the pre-outs from your receiver (if it has one) or the sub pre-out. hope this helps

1 subs and 4 speakers is the desired load for a 200w unity, running 2 subs and 8-10 speakers is an ask for the 200w. However, if you are going to do it a single 450w unity would be better or daisy chaining 2 200w unity using RCA with 1 sub and 4 speakers off each amp. To each there own, but in short the single 200w might be able to do the job but, more amplification is better especially if you have a large distance between the amp and speakers.

Could I use two of these, linked through the line-out, to power a pair of bi-amped speakers? I figure without a crossover, they would be sending the same signal to each of the speakers (L and R, Hi and Lo).
Bruce J
on Feb 25, 2018
BEST ANSWER: You technically can, but you shouldn't. Without a proper crossover before the amps the full range signal you send to the speaker will make the woofer sound very muddy and will most likely blow-up the tweeter. Using the bi-amp setting on your speakers will bypass the internal crossover.

- Dave L Staff on Sep 27, 2018
The short answer is that it depends. The long answer is that any amplifier can drive multiple speakers, but you have to watch the impedance load the amplifier sees. Lower impedance results in more power, but also more heat. If the amplifier isn't designed to run lower than rated impedance, it'll damage the amplifier eventually. The way you wire speakers also affects impedance, so you can take several 8 ohm speakers and still end up with an 8 ohm load - but if you connect those same speakers in a different way, you could end up with a 4 ohm load, or 2 ohm, or even 16 ohm or higher. If you are going to try and do this, you'll want to research connecting speakers in series and parallel, and how that changes the impedance of the group of speakers.

There are two sets of speaker posts, so two can be directly connected, though the amplifier is quite stable and capable of handling several speakers on its two channels in stereo, bridged mono, or even as two separate channels when wired appropriately with impedance matched. You can also use the linked impedance matching speaker selector if you are looking to use in a multi-room setup or don't want to try and match the impedances to the amplifier with multiple speakers and would also like easy volume control.

Brian S
on Jun 6, 2019
BEST ANSWER: We do not recommend. Bridged mode is only stable to 8Ω. If you try youwill need to use 16Ω speakers. These do not have a fan so you will want to closely monitor so you do not overheat. Let us know how it works.

A simple x-over (inductor in series with the woofer, capacitors in series with the main speakers) would ensure that total impedance always remains above 8 ohms at bass frequencies (where most of the power draw happens).
The biggest problem with tri-mode configurations is matching the sensitivity of the subwoofer with that of the main speakers, as there's no real way to adjust the output of the subwoofer in relation to the main speakers.

No. It doesn't have the extra connections for the bridged part. It's either a 2 channel amp, or a 1 channel amp - not both. The tri-mode thing started with car audio, but leads to all kinds of messy problems, especially for the crossover that you inevitably want for the subwoofer that's using the bridge setup. It's far better to simply run 2 amps - one stereo, and one bridged.

It’s not clear what your trying to do. Are you using the amp to add additional powered channels to an A/V receiver to set up an Atmos surround system or are these discrete speakers.
As far as driving subwoofers you need a purpose designed amp for low frequencies not a full range amp. Normally these are powered subwoofers or a special amp supplied with a LFE signal from the A/V receiver.

This is a question for someone familiar with the Sycamore system. The 450W amp is rated for 4-8 ohms so you have to be concerned with overdriving or under driving the amp with regard to the resistive load when you use more than 2 speakers. The amp only has connections for 2 speakers.

That depends on the power requirements of those speakers and how loud you want them to play. But you can't simply connect four speakers in parallel to each channel because that would present a 2 ohm (or less) load to the amp and possibly cause it to cook itself to death. The amp is rated for a minimum of 4 ohms so, if your speakers are 8 ohms each, you could get two amps and drive two pairs with each one. If your speakers are less than 8 ohms (6 ohms is common), then you'd need an amp for each pair (although the 100 watt version would probably be sufficient). I'm only driving a single pair of Dolby Atmos speakers with mine (because my receiver has 11 channels of processing but only 9 channels of amplification).

If you connect 2 of the speakers in series, then connect 2 of those series pairs in parallel, the amp will see the same impedance as a single speaker.
Repeat the same for the other 4 speakers to the other "side" of the amplifier output.
For in-ceiling use, 100W/channel should be plenty powerful.
Repeat the same for the other 4 speakers to the other "side" of the amplifier output.
For in-ceiling use, 100W/channel should be plenty powerful.
You can drive 4 - 8 ohm speakers and still maintain an 8 ohm impedance if you connect the speakers in the following manner: 2 sets of 2 speakers, connect each set in series, then connect the sets in parallel. The final resistance of the combination will still be 8 ohms. To simplify the setup, split the output of the amplifier in two, then use it to drive two speakers in series - ( SERIES = right positive amp -> speaker 1 positive -> speaker 1 negative -> speaker 2 positive -> speaker 2 negative -> right negative amp ). Honestly though, I would just buy a second amp.... running speakers in series creates quite a lot of feedback and can significantly increase the amount distortion.

Hey Roger H,
Roger J here. Even though the best venting orientation is obviously horizontal, my personal experience is this amp doesn't get very warm at all, even with fairly high volume levels for an extended period of time, so I personally wouldn't worry too much about mounting it vertically on the wall. However, I don't think I'd be comfortable mounting it in a way that would block the vents. I hope that helps.

BEST ANSWER: Yes, you can. Since most receivers put out the same sounds to both subwoofer outlets, I currently use this amp in bridge mode, and then split the output off to both subs. You get more power to each speaker that way.

Yes the preamp and amp outputs are both active at the same time so you can add additional amplifiers and have them on the same zone. Note that the volume control only changes the amplified output so when you turn the volume up and down with the keypad or serial port it won't change the volume of the external amp

Thanks Randal... that is very relevant information! Essentially, I would have to set the external amp to the volume level I would most likely want the speakers to be at as I would not be able to adjust it from the keypad. Are their any possibilities to have the volume control from the keypads change the volume levels of external amps?
Page 3 of the user manual states the system's volume controls do in fact control the RCA preamp outputs.
On my current muti-zone amp i leaved the volume on the powered amp at max volume and adjust the volume using the preamp. Is that not the case with this unit?

- New User U on Apr 6, 2018
Yes. The user manual shows a diagram on page 10 where a sub-woofer is connected to the pre-amp outputs and speakers are connected to the speaker output of the same zone, so both will work together.

Yes I know not bridged. The AV reciever has two powered subwoofer outputs. Would it be better to get an amp for each sub? Haven’t gotten any of the components for the build yet. I would like to have 1 av reciever and two in wall subs.
I am always a fan of more power. You can always turn it down. I'd get 2 x 200W amps, bridge them mono, and adjust the volume to the appropriate level. Bigger amps turned down will run cooler with less distortion, and you are more likely to blow up a speaker by underpowering than overpowering.
Don’t you mean less likely.
Can you split the trigger output from the Av to trigger each one of the 200w Amps
So 1 av reviver with two sub outs. Each out goes to a separate amp then each amp is bridged to power 1 sub each.

I do mean more likely. If you underpower you run a greater risk of clipping the amp which can do immediate damage to speakers vs. overpowering. Speaker will handle excess power for a while, you will hear the over extension and have time to turn down the amp to avoid damage.
The Unity amps have trigger in and out so you can daisy the trigger out of your AVR.
Yes, take the 2 LFE outs from your AVR to the 2 amps.

The trigger is not necessary. You can set the amp to the Auto setting. The amp will power on when it receives signal from the AVR. It will return to Standby when there is no signal present for more than 5 minutes.
The trigger allow the amp to power on and off with the AVR.

If you buy a single RCA to double - yes. It has plenty of power to move the subs. I have a rack with four of these in the media closet and as long as you have good ventilation (I’m using 140mm computer fans) to keep them cool, you will be surprised what they can do...

If these specs are correct, I can power four(4) 8 ohm speakers off the two channels on the Unity 200-watt amp (4 ohm load), at 62.5 watts per speaker - which is 12.5 more watts per speaker than getting two(2) Unity 100-watt amps to power the same four speakers (50 watts @ 8 ohm load) while saving space in my rack - with the only draw back being the higher THD and perhaps higher heat from running the amp at 4 ohms? Am I thinking correctly?

If you run an amp at high power, especially if you run it for a long periods, you will certainly damage the amp long term... More power = more heat = more signal degradation / damage. In most instances, you are better off running two amps at a lower power for longer than a single amp at full power. Of course, this totally depends upon the volume that you wish to derive from the setup. If you're only going to operate at 10 percent power, no issues. However, if you're running at 90 - 100 percent, because you want lots of volume, you're probably better off running two amps at 50 percent.

Yes, it is a 2 channel amp and you can use it for 2 subwoofers. But typically with subwoofers, you can bridge the channels (switch at the back of the amp) and wire the 2 subs in parallel so both get the same signals at 8 ohms.

It’s my understanding that when you bridge the amp, it is 225 Watts in a single 8 ohm load and not 4 ohm. All of my speakers are 8 ohm so I’ve only had good results with this amp. I have actually purchased 14 of these amps that I use in my whole whole audio system with two of the 6 Zone each distribution, class d digital amps. I`n rooms with 6 ceiling speakers and 4 wall speakers and 2 SVS PBUltra 16 1500 watt rms or 5,800 watt peak each of the two subwoofers, I use the amps connected normally to the speakers. In rooms that will only fit two ceiling speakers, like two of my bathrooms and the laundry room, I use two of these amps and bridge each one to one speaker to get the most bang for my buck from those two ceiling speakers. The pair then gets a full 450 Watts as ass kickin’ class d, digital amp power. I really have enjoyed these amps and I would highly recommend them. I’m not exactly sure what your set up is or how you’re planning use them but for my situation, they are cool as can be! I guarantee that my whole home audio system puts 99% of the thumpin’ night clubs to shame. My two home theaters deliver more bang and better sound than any commercial movie theater that I’ve ever been to. I can re-watch movies that I’ve seen multiple times in the past because it’s like a whole new experience now. Unless I’ve watched it with this set up that I have now, I just consider it a brand new movie.

What it sounds like your question is, is, "Do the line outs from the amp still pass-thru signal when the amp is off?"
I would suspect the answer is yet as it's probably just a Y-connect from the line-in to the line-out (and to the amp itself as the other end of the Y).

One failed after 3 years
I have two separate systems each using one of these units (200W) in bridge mode to drive an in-wall subwoofer. One unit stopped powering on after about 3 years. No power, no lamps, etc. I confirmed no shorts, speaker cabling around 8 ohms, and swapping the two units confirms that the one unit just died.
Unfortunately past the warranty and past the extra year of warranty from my AMEX. Not sure whether to replace it with another or look for something else.

I've been using this power amp for about 3 weeks now. So far very pleased. Used it as a power amp for additional 2 ceiling speakers connected to an Anthem preamp using its 12 trigger function. Everything works perfectly and the sound quality and power delivery are as good as I expected for an amp of this type and price. We'll see how reliable this amp is over time.

Great amp for the price!
I'm enjoying this amp! I have this plugged in with RCA cables from a Pre-out on my Yamaha receiver to power some outdoor speakers. The speakers are the Monoprice Burial Sub and some of the larger Monoprice outdoor speakers Product # 13614 and Product # 31035. I don't have a trigger out from my receiver and just rely on the auto turn on. It takes about 5 seconds after I start playing music for the amp to wake up and start working, but it works well and the music sounds pretty decent! I'm thinking about buying another full set of speakers and another amp but it would probably be overkill for my deck of around 1800 sq ft. I've seen reviews complaining about a hum or loud thud when it turns off, but haven't experienced any of that. Works well!
