This has sub output. Is there a high frequency cutoff - and if yes, is it adjustable? Also, for speaker amp, is there a low frequency cutoff to match?

Fixed in both cases, I believe. The manual is downloadable from nadelectronics dot com with details.

The speaker out will be filtered below 80Hz, and it is fixed, that's what I got from NAD support...

Thanks for your question. One of the amazing shopping tools that the internet provides is the ability go to the manufacturer's site and download the full user's manual. We've never had this opportunity in the past and it is an amazing way to study everything about about a piece prior to purchase. This is a fantastic sounding amp. World Wide Stereo is 35 years old and a very proud NAD dealer.

Yes Andrew this sub will play down to 30hz with a fair amount of output,it will also play below that frequency, however you should not expect a high db level below that as it has a small driver by subwoofer standards and based on that you should have a reasonable expectation of its limitations based on that... This is a very good sub FOR ITS SIZE... I hope this helps in your decision.. Any more questions don't be afraid to ask.. Happy new yr!

I have a powered sub that accepts speaker-level input, and it works great attached it to the "B" output (I am only using the "A" output for my main speakers).

there are no "universal" settings for amps, it depends on the amp, the headunit and the subs being powered.

Yes. It's a 4 channel amp so you will have to bridge 2 of them. If you are running subs on another amp the cut out issues could be from lack of power from your battery/alt. Try adding a compacitor..

At 600ohm The ZxR has 5.4v (rms) the ZxR line outs have 2V RMS for maximum range. I could get more info if you need. This is some info I've found, might give you an idea. I will be feeding the analog line outs into the Emotiva UPA-700 amplifier. As I understand it, the ZxR line outs have 2V RMS for maximum range. The UPA-700 has 870 mV RMS for maximum volume. I don't want to either overdrive the amplifier or blow my ears out by accidently using maximum volume. Can I use the Speaker Level settings to change the maximum line out voltage? Setting each of the speakers (except the subwoofer which is separate) to -7.3db should do the trick. If that is correct, then 100% volume would match 100% speaker volume. This would be, of course, independent of minor tweaks for room adjustment or of equalization. Am on the right page here or do I need to add a preamp into the picture? -I would imagine that should do the trick, if you wanted you could try putting some resisters in the connections to dampen the output, though I'm not incredibly sure what impedance you would need and what effect it may have on the frequency response, you would want some high quality ones... in my case I just have my computer volume set to 50% and adjust volume via my amp, I know why you need yours the other way round but the concept is pretty much the same, I wouldn't expect you would need the full 0-100% range so I don't think you could ever have it set too high for a long enough amount of time to damage the pre-amps in your UPA-700, just set the amp to a high enough value that you can get a good range in your pc volume while not too high that you pick up interference or loose the ability to go really quiet, and there's usually a point in any sound card that they loose quality after a certain volume (hitting the DAC's clip if you will).

What's the frequency response of the mains? You will likely see the need to adjust the sub's high end slightly above the low end of the mains, using a cable into the l/r input jacks. Or you could use the crossovers in the receiver, set the speakers to small, crossover wherever you think the low end drops off on the mains... usually 10 hz above the listed specs. Then connect the sub the the lfe input, that bypasses the crossover in the sub.

There is an input to bypass the amp called "speaker level input" but that would really take away the nice part of this speaker. I would try to get a line level output from the mixer if possible and use the subs power

If your amp has a 2 ohm output impedance, it will drive 4 ohm speakers, but you won't be able to attain full dynamic range. I believe this sub comes in a 2 ohm version, just buy that one instead. Or buy 2 4 ohm subs and wire in parallel.

With that speaker the amp has to be stable at 1 ohm I ended up changing the sub to the 4 ohm one because of the dual voice coil it has actual 2 ohm. The amp I bought was only stable at 2. Just depends on what you like truly.

The specs for this amp indicate 40 watts of power for each channel....so I believe it would be within your speakers' parameter.

I did some brief reading about how to match amps and speakers, and my understanding is that the amp's power rating should be less than that of the speakers--around half the peak rated wattage. But as well as power you have to make sure the impedance of the speakers matches the output impedance range of the amp. If you're running two 8 ohm speakers in parallel on each channel, that's actually 4 ohms, so check those numbers. We use this Grace BTAR122 in conjunction with two 80 watt Polk Atrium 4 speakers and it sounds fantastic.

Never turn it up to 100%, it will be boomy and heat the amp up. I would think these things have smart protection circuitry (besides their fuse) in them to prevent catastrophic failure. Just adjust it starting mid way ~50% and go higher until you find that sweet spot and only you know what kind of sound you are looking for. Remember to adjust the frequency to take some of the boom out of it too. You should have one sweet sounding sub when done correctly.

The FBQ3102 has a subwoofer output on the back. You can either attach that to a powered sub woofer or another amplifier. If you don't have that, then you will need to adjust the parametric EQ on the left. Pick a freq around 500 and turn up the gain

There is not a "high level" output on the unit. There is a "high level" input for older receivers that do not have a dedicated subwoofer output on them.

The picture is showing the same sub, but different aspect. There is only one "sub woofer speaker." Your amp will generally have one output for a single subwoofer.

This is a bit like asking "how do you cook?" There us no one best way to hook up a sub... you need to divide the frequency of the signal into the frequency range your speaker responds to. There are many ways to do this... a crossover network can split the input (your music) into "sub" and "everything else" before the amplifiers and use separate amps for the subs and everything else... but thus is only one solution. Tell us what equipment you are trying to use and perhaps you will get a more useful response.
