Can i hook up a power amp to my Nad 7155 receiver and how


If the Nad has pre-amp out sockets that are currently connected to the power amp in the receiver. Then you can sever those link and put the pre-amp out into your Aragon inputs.
Otherwise I don't see how you can connect the amp.

NAD C740 Chanel B Speakers not working The speaker output A is working properly, then the output B is completely silent. I install differents speakers and even the same speakers. no sound from the B...


possibly the causes are: 1. defective channel B power amp board. But try operating first with the built in tuner, if it's ok the RCA cable from your other sources(DVD player, etc...) might have broken internal conductor.
2. if it has the speaker switch(A, B, A+B) try toggling it, might also just loose contacts.
if the trouble is #1, leave everything to your trusted qualified technician, he knows what to do, unless you want to tweak/repair it by yourself...hope this helps ;-)

Definitive Technology Mythos STS SuperTower loudspeaker are a good match for a NAD M3 integrated amplifier?


Hello,
For the most part, it depends on the power output of the amp and the requirement of the speakers. Its a good idea to have at least 10% more power at your amp than what your speakers require.Find out what those values are if you don't already know and that will give you a better idea

No signal from sub connected to NAD T760 in test mode.


Try using front pre out to the sub from the receiver. the crossover is in the sub anyway. If this works change your settings on the receiver and test again. If sub is still inop, could be an internal issue with the sub amp. Does your sub amp have an on/auto/off switch or light? check that as well. Hope this helps, if you need further assistance, send a reply and I'll help some more

My NAD T753 goes into protection mode as soon as I turn it on.


The unit grounding screws have come loose. All the ground screws should be tightened.

Using NAD t743 with Panasonic DMP-BD55


The reciever you have has 5.1 inputs at the backof it.The only way to get Dolby True HD and DTS HD is to run the 7.1 analog out from the bd55 to the nad. You'll have to leave the 2 rear surround open on the bd55 leaving the remaining 6 connected to the nad. The digital coax and the optical will not transmit the hd data, only the analog out will. Run a hdmi right to your HD tv for picture bypassing your amp. this will workfine and you'll have the audio you want. You,ll have to change the input settings for dvd in your amp to 5.1 to recieve the audio.

Can I connect a power amp to this unit?


If your 2100ES has a selectable INPUT AND OUTPUT and if you're intending to send all signal to the power amp, i.e. not bi-wiring or using the 2100ES to run mid-range or treble then you simply send Left & Right audio (White & Red cable) from a 2100ES output, probably AUX OUT ( it doesn't really matter apart from Phono on some units) straight to the power amp on AUX IN.
We should be just dealing with audio here, so connect the NAD audio output to CD or DVD IN. Select CD or DVD IN on 2100ES input switch and switch output to AUX OUT (whatever you decided goes to the power amp) on the 2100ES. Turn power amp to AUX IN and it will now get an audio signal from the 2100ES for amplification.
Speakers connect to the power amp as a normal amp, so pos and neg etc. The 2100ES now only acts as a signal feed, the power amp does all the work.

So, summary - switch on the NAD, press play - video goes separately and audio goes to the 2100ES. Turn 2100ES to INPUT for NAD. Turn 2100ES to OUTPUT allocated for power amp. Turn INPUT on power amp to allocation for 2100ES.

Turn it up!
