Bi-amp or Bridged Mono?

Hi sounds great,
U are right. I have never seen line outs on power amps but i guess i learn new things everyday. Thanks for pointing it out. Are these pics of models for asia or for the EU? If i remember correctly the back panel of my nad pre was not exactly the same as the one in the picture.
The variable pre out(preout 2) on the 162 matches the output of the fixed (pre out 1) when turned to the maximum position. Basically so u can use non identical power amps.
My suggestion to look at a dedicated stereo pre like the 162 is firstly to improve the sound as compared to an AVR as the pre and secondly to have the convenience of having 2 pre outs.
Silentsound now u have all the options available to experiment!!!!!!!!

Hello Dinyaar,

First of all thanks for being considarate,before posting it I was bit hesitant to point out thinking where I might offened you ! but then I thought its my duty to point out certain things as we both are trying to help,so did it.

the Amp is Asian ! as for the Pre, I tried to look it up yaar but they've not specified whether its the asian are what,So I dunno !

And with respect to your comment on keeping the 2nd pre-out volume full, how does it works with main volume ? Am not very sure, coz the very reason of providing an volume control is to control independently from the main, atleast this is my understanding.

please shed some light on this !

Regards

Hi Soundsgreat/Dinyaar,

Thanks for your valuable suggestions and taking time to do so.

Soundsgreat,

My Nad 2400 THX power amp back panel looks like the one you've attached. But the rca jacks you've highlighted labelled as 'LAB'. What does this mean? I'm not sure whether these are preout jacks. Let me know.

Dinyaar,

The main reason I prefer the avr over a stereo pre-amp is, I'm using this setup for movies also. This way I don't have to switch the wires when I switch from movie to music vice versa.

About the preout volume knob, when its at maximum level, its as if there is no difference between the two pre-ins. Thats what I understood.

Hi Soundsgreat,
Why would i get offended buddy? U have pointed out something that i had overlooked and did not know. In fact i am grateful for u correcting me.

Ill explain what i understand it as soundsgreat. I had this pre for a year but never used the variable pre out. Suppose i am using the pre with say one amp which is 100 wpc and the other is 120 wpc. I would connect the 100 watter to the fixed pre out and the 120 to the variable and then while i set the master volume at whatever level would raise the variable volume to match the output/sound pressure level of the other stereo amp.

Once again if i am wrong please do not hesitate to correct me as otherwise our dear friend silentsound might end up blowing something!!!!!!!hahaha

Regards

Dinyaar., you are right ,
The pre 1 and variable pre 2 can be connected to different power at the same time and both the pre outs will be controlled by the main volume control. And if you want the volume to match the other power you can adjust the variable volume control on pre2 . I have used NAD C 160 to my Rotel Power 980 and 960 for bi amping.

HI soundofmusic and dinyaar,

Thanks for bringing clarity on this issue !

The main reason why I this doubt in the first place was,I have seen many high-end P.A booster amps with the 2nd pre out where its volume is controlled by the volume control thats it has and its not related to the main volume in any way ! thts why I had this doubt !

anyway lets not deviate from the main disscussion which is to help our friend !

As with your query regarding the lab input. the pic I've attached is the asian version which had line out as dinyaar was mentioning the Asian and Europe Version, your's might be europe version ( oh god why they do this ! ) so I checked this out, infact I just got a NAd 2100 from a friend which has same lab input.
after checking out and trying diff things I came to conclusion that this might be a premitive type of balanced inputs that we find in todays date ! so they are not lineouts !

Now we are left with very few or nill options for Bi-Amping !
Am just trying figureout a way around this issue please wait(any how you are waitng for the 2nd nad to arrive )

Hi

IMO its not possible to Biamp using a AVR receiver , even if he uses a Y separater , the quality is compromised. the best possible way is to bridge the 2400 into Mono and use one amp for each speakers.
