Connect subwoofer etc to nad 3020I stereo amplifier
Cannot find instructions now, had them for years.
I have connected my variable sound out from tv to the tuner in on my amp, tried the gold plated phono but nearly blew the satelllite speakers on trial !!?!!
So into the tuner I have gone...
I want to connect a sub to it, so I have tried various routes taking these arc connectors/plugs out using the pre out to plug the sub in, does work, but then I am looping back from pre in in to aux inputs to get sound through satelites!
Must be a simpler and more sensible way, to it and to use the power of phono!!!
Want to get this right before I get a really good sub, and or get a 5.1 amp, don't really want to ditch the nad 3020I

You can use a 2 x male RCA to RCA female adaptor lead(what you need to ask for) like this one
use it to jumper your pre-out/main in connection on the rear, and connect an RCA lead to the Female socket on the adaptor lead. That will get you going. You can get them most places that sell electronic bits and peices. I am happy to answer any questionsa you may have
a 6ya expert can help you resolve that issue over the phone in a minute or two.

You'll need some type of amplifier to drive the speakers. The Samsung TVs mostly have a line out and a headphone out, but that wont drive speakers unless they are powered speakers like PC speakers or a powered sound bar. (Like the Pioneer SP-SB23W soundbar/subwoofer) If you have some of these get a mini 1/8" stereo plug to RCA plug adapter from BestBuy or similar. If you have PC type speakers, You'll need a 1/8" mini stereo patch cord to go from the line out to the speaker input. (Set the audio out on the TV to variable so you can control the volume with the TV volume.)
AVR-E400 has an RCA subwoofer output. This is a line level signal that must be connected to an ACTIVE subwoffer (has its own power amplifier) Also the source must contain subwoffer signal (5.1, 7.1, 9.1 surround sound etc) You will not get subwoffer signal from a stereo source such as audio CD, non-dolby type TV etc. Cheers, Don.
I have looked at an image of NAD rear and it has RCA type jacks. I would plug it into the AUX sockets. Now to if it will work. Plug some stereo headphones into the iMac socket. If you can hear sound then the cable you intend to buy will transfer the sound you hear to the amp. If you want to record from the amp to your computer you will need another a different input on your computer and that would need to be connected to tape 1/2 out. Any 3.5mm socket to RCA will do, they are not expensive plenty of cheap ones on Amazon and E-Bay (image shown). You will need two if you do want to record as well.
To setup the Bose 901's so that all of your connected equipment's sound (cable/dvd/games/stereo/etc) comes out of the 901's. If you already have a receiver with front left and right pre-outs, I would add an amplifier. (other option is a pre-amp) Use the amplifier to create the loop the 901's need w/ their EQ and it will also add a cleaner sound and added power. That's how you can really make the Bose 901's sound amazing.
this subwoofer has a built in crossover variable from 50hz to 150hz which means
that any signal you feed it the sub it will ignore anything but bass anyway. As for the
connection it is made quite difficult if you don't already have an amplifier
powering your other speakers, usually home cinema amplifiers have a low level
pre out for subwoofers, for which you would just need a phono to phono cable. However if
it doesn't and you have any type of amplifier with at least 2 separate left and
right speakers you can connect the wires from these into the subwoofer and it
will output the bass from these 2 channels. Another
option is to use a mono to stereo (2 to 1) phono cable where the 2 connectors
at one end connect to a tape or record output on your amplifier and the single
phono at the other connects to the subwoofer, the same would go if you have a
red & white phono (RCA) output on your TV you could also use this to power
the sub, in the worst case scenario you could use a single to single phono or
rca cable to connect one of the output channels (left or right) on your TV to
the subwoofer however this would mean that the subwoofer would only output bass
from either the left or right channel.
A home theater system usually consists of a dolby digital stereo amplifier and 5 to 7 speakers.
Turn your stereo on and select the source that delivers video to the TV (DVD, VHS, Game, etc.). The video may be connected directly from the device to the TV, but the audio should connect to the stereo system (DVD, VHS, or other input). This way, the source audio is sent to the stereo and it provides the big sound to match the picture. Otherwise, you'd have to connect the source audio to the TV and let it's comparably tiny amplifier and speakers provide sound - that comes up short.
When playing a DVD, select the DVD input on the TV *and* the DVD input on the stereo. If you do not connect the audio to the DVD input on the stereo system, you'll have to connect to the TV, otherwise nothing will be heard.
You clearly understand that you need to use a variable line out to control the subwoofer volume via the TV. As the setup seems reasonable, I'm wondering if the subwoofer is getting a signal, but that it is at line-level and not internally amplified by the subwoofer speaker. Generally, if the subwoofer must be plugged into an AC socket in the wall, it has an internal amplifier and can be fed line-level audio. If it is "passive", it has no amplifier, and it must receive an amplified signal (over speaker wire) from an amplifier (or integrated receiver). TV's don't generally have connections to send out an amplified signal.
If the subwoofer is indeed amplified, then this is obviously not the problem, but it's the first thing to verify given the information provided.
