    Default Question about Carver Amp and Integra Receiver

    Hello,
    I ended up buying a Carver TFM-45 to power my Polk LsiM705s and hooked it up to my Integra receiver (DTR 6.8). However, I still have to crank up the volume on the receiver to hear it a decent level (not even close to ear bleeding volume).

    The receiver goes from -81db and I'm at -15. Is this right? Do I need to adjust a setting on the receiver?

    This is my first time ever using an external amp so I am very new to this all. Thank you in advance for your replies.

    No idea but someone will ask anyways..

    How do you have the receiver and amp hooked up? Pre-Outs or line outs on the receiver? Is there settings on the back of the amp that your using?

    I can see from pics that theres a button near the left side that says "Push in for mono Bridged" Is that pushed in? You don't want that active if your using 2 channels (2 speakers).

    Unplug the amp before messing with that button though.

    I'm sure it is a setting issue within the receiver.

    I am using Pre-Outs. On the back of the amp the MONO button is turned off.

    Ok well as long as you have the speaker wire removed from the same channels on the receiver end and you have the mode on stereo it should be pumping loud. Just don't keep it cranked on the receiver while you mess with the settings cause when you get it straightened out its gona blast you with serious volume! haha.

    Are you hooking the amp up to the Front Left and Right out or using the Zone 2 outs?

    I looked in your manual and it said something about having to set what controls the volume if your using zone 2 nothing really about what settings to make using just pre-outs. Only other thing I seen was settings to make for using bi-amping but your not doing that.

    Only other thing was in the beginning they mention that theres no digital to analog transfer on this receiver.. meaning if you have HDMI in it will not convert that and send sound out the analog channels. No idea if that's related or not?

    Have you tried just playing different sources like the Radio atleast?

    Heres another stupid question.. Do you have the receiver set to the right ohms for the speakers if that matters since he's using a sep amp and is the amp rated for the ohms of the speakers? Meaning the amp will work with 8ohm speakers and your speakers are 8 ohms?

    No idea of the speakers your using.

    Oh and the speakers are set to large or small on the receiver? Crossover settings?

    No idea as its been years since I've ran a separate amp for my fronts and then I was just playing around with it.

    Well, this is interesting (maybe it is). My receiver says +7db but the needles on the amp are reading the db for each channel is between -40 and -30.

    I think your worried that the numbers do not match up Correct?

    Those numbers are for the power section of the AVR disregard them I have a Denon 3805 that I'm running a TFM25 through I routinely have it at +25 or more by the numbers in the receiver it means nothing just keep an eye on the meters and don't worry about what your receiver says.

    Ok, Thank you.

    I changed out the cables that were connecting the amp and the receiver and that made a difference.

    You are getting the 705s? You are going to love them. I have them in the Cherry finish. Not only do they look gorgeous they sound fantastic.

    Thank you for your help. I think by changing out the RCA cables it did the trick.

    That may very well be and I do not doubt that but wires well never get the numbers to match like if you were just using the amp section in the receiver.

    That's awesome. I really liked how the Lsi15's sounded but pushing 4ohms seemed a bit crazy to me. Also, me and my husband think these look a lot better than the 15s.

    Do you recommend any certain type of cable to connect the amp and the receiver?

    buy better cables than either one posted. You have top grade speakers so do not skimp. Better inexpensive cables can be found at Blue Jeans cable or signal cable and we get a small discount at signal cable just tell Frank you belong to club Polk.

    well both of those work yes
