Help with an Akai AM-U3

Hi first post,sorry if its a bit of a ramble.
I have a large collection of flac files stored on a pc,the software used for playback is kodi.
The present set-up line is out from a m-audio sound card to a pair of Nad 302s,
I have connected the amps so that all audio inputs go into what I call the master amp the second amp I call the slave.From a tape out on the master,the audio is fed into a tape in one the slave and when the Tape 1 Monitor switch is depressed the amps are linked with manually set volume controls
the audio is then sent to a pair of bi-wired B&W speakers.
The problem I have is though I have set the pc's and the software volume to 100% the amps acceptable volumn output is 50%,but if I play a cd at that level its bloody loud.
The Nads are pre remote control so there have been times when Ive nearly blown my windows out by forgetting to trim the settings.
To get over this I picked up the Akai to use as a pre-amp/volumn control from the soundcard,to confirm the amp is working I connected a cd player and speakers to check everything is ok which it is,what I cannot work out is :I have connected the soundcard to the Akai repeated the test which works,but I cannot send a signal out from the amplifier using the tape loops.
I have tried online searching for a user manual with no joy and Im confused if output is possible or if Im just pressing the wrong sequence of buttons.
Any help please.

If you connect a line level source (CD, tuner, sound card etc) to the Tuner or Aux input it will be routed directly to the Tape 1 record out sockets when you select that input. You won't be able to control the volume with the Akai though as record out sockets come before the volume control; the Akai will just act as an input selector. For variable volume output you really need an amplifier with Pre Out sockets.

Re: Help with an Akai AM-U3

Point taken,but I cannot route the output from the tape loops,using a temporary setup of pc and cd source to speakers.I can get sound via tuner and aux input but I cannot get sound by plugging source into tape in then feeding the Nads with tape/record out,Iam very unfamiliar with this Akai,I am comfortable with analogue but this amp claims in an early 1980s fashion to be a "computer controlled amplifier",and Im sure I could get audio out from the loops by activating the tape monitor or passthrough if I could work it out.
Ive re read and thought about your comment and yes Ive got it to the extent that Ive just looked at the CD and MD players,Marantz CD5400,Pioneer MJ-D707 and noticed that the levels are set on 50%.I could trim them to match the PCs output.
I had never thought about that,but even so I still would like to sort out the issue with the Akai's output.
Thank you very much for taking the time out to reply.

Re: Help with an Akai AM-U3

If you plug a line source into Tape 1 and press the Tape 1 button to select it as the source, you should get output from the Tape 2 record out sockets? This is to allow dubbing from Tape 1 (playback deck) to Tape 2 (recording deck).

FWIW as this is designed to be used as a tape loop, the Tape 1 playback sockets are not routed to the Tape 1 record out sockets as this would cause a feedback loop.

Re: Help with an Akai AM-U3

Yes I've followed your instructions and it works,and as you have explained the Akai is just an input selector,though I can benefit from that as I have more audio players than ports on the Nad and Im routing their sound through a Yamaha DSP-AX640SE,and messing with the settings on the remote after a few drinks is not a good idea.
Thank you again for your time.
